Pro Tools|HD Systems

Pro Tools|HD systems are available in the con­figurations shown on page 6. Each system re­quires at least one Digidesign audio interface (sold separately). Pro Tools|HD systems can be expanded by adding Pro Tools|HD system cards to increase track count, add to the amount of possible plug-in and mixer processing, and con­nect additional audio interfaces.
Pro Tools system performance depends on factors such as computer processor speed, amount of system memory, and hard drive performance. Contact your Digidesign dealer or visit Digidesign’s Web site for the latest system requirements and compatibil­ity information.

Pro Tools|HD System Playback, Recording and Voice Limits

The following table lists the audio playback, recording, and voiceable track limits of each type of Pro Tools|HD system. Playback and recording voices refer to the number of unique simultaneous playback and record tracks on your system. Total voiceable tracks refers to the maximum number of audio tracks that can share the available voices on your system. (Mono tracks take up one voice. Ste­reo and multichannel tracks take up one voice per channel.) Voice limits are dependent on the ses­sion sample rate and the number of DSP chips dedicated to the system’s Playback Engine. Pro Tools|HD systems can open sessions with up to 256 audio tracks, but any audio tracks beyond that system’s voiceable track limit will be automatically set to Voice Off.

Pro Tools LE System Capabilities

Table 5 lists the playback, recording, and input and output capabilities of each Pro Tools LE system. Mono tracks of simultaneous playback refers to the number of unique simultaneous playback and record tracks on your system. Total voiceable tracks refers to the maximum number of audio tracks that can share the available voices on your system. (Mono tracks take up a single audio track, while stereo tracks take up two tracks.) If you open a Pro Tools session created on a Pro Tools|HD system containing more than the number of tracks supported on the LE-based system, audio tracks beyond the LE system’s voiceable track limit will be automatically set to inactive.

Chapter 3: Pro Tools Concepts

This chapter explains the principles and con­cepts that form the foundation of Pro Tools op­eration and functionality.

Hard Disk Audio Recording

Tape-based recording is a linear medium—you need to rewind or fast forward a tape to hear a particular spot in a recording. To rearrange or re­peat material in a linear system, you need to re­record it, or cut and splice it.
Hard disk recording is a nonlinear (or random ac­cess) medium—you can go immediately to any spot in a recording without having to rewind or fast forward.
Nonlinear systems have several advantages. You can easily rearrange or repeat parts of a record­ing by making the hard disk read parts of the re­cording in a different order and/or multiple times. In addition, this re-arrangement is non- destructive, meaning that the original recorded material is not altered.
Pro Tools is a nonlinear recording system that lets you rearrange and mix recorded material nondestructively.

The Digidesign Audio Engine

DAE (or Digidesign Audio Engine) is Digi­design’s real-time operating system for digital audio recording, playback, and processing. When you install Pro Tools, DAE is automati­cally installed on your system.
In the same way that a computer’s operating system provides the foundation for programs that run on the computer, DAE provides the foundation for much of the hard disk recording, digital signal processing, and mix automation required by Pro Tools and other products from Digidesign and its Development Partners.
The DAE Playback Buffer Size determines the amount of memory DAE allocates to manage disk buffers.
For information on configuring the DAE Playback Buffer Size, see “DAE Playback Buffer Size” on page 45.
The DAE Playback Buffer Size can be changed in the Playback Engine dialog (see “Playback En­gine Dialog” on page 14).
Chapter 3: Pro Tools Concepts 13

Playback Engine Dialog

Pro Tools takes advantage of your computer’s host processor for certain tasks and optional host-based DSP processing.
Pro Tools LE uses host (CPU) processing to pro­vide audio track recording, playback, mixing, and effects processing. Pro Tools HD can also use host processing to run RTAS plug-ins for ef­fects processing. Performance is determined by your system and its Playback Engine settings.
The Playback Engine dialog lets you set a hard­ware buffer size and allocate a percentage of CPU resources for these tasks.

Pro Tools Sessions

When you start a project in Pro Tools, you create a session. Some basic elements of sessions are ex­plained in this section.

Session File

A session file is the document that Pro Tools cre- ates when you choose File > New Session and configure a new session. Pro Tools can open only one session file at a time. The session file is named with a .ptf (Pro Tools file) extension. Ses­sion files contain maps of all elements associ­ated with a project, including audio files, MIDI data, and all your edit and mix information. It is important to realize that a Pro Tools session file does not contain any media files (audio or video). Instead, it references audio, video, MIDI, and other files. You can make changes to a ses­sion and save those changes in a new session file. This lets you create multiple versions of a session or back up your editing and mixing work.
Playback Engine dialog for Pro Tools HD
On Pro Tools|HD systems, you can select the number of voices and voiceable tracks for your system and its sessions. Voice count choices are based on how much DSP processing you want to allocate for voicing.
For more information, see “Configuring Pro Tools System Settings (in the Playback Engine)” on page 41. See also “System Re­sources” on page 18.
On Pro Tools|HD systems, the Playback Engine dialog is also where you assign dedicated DSP re­sources for Delay Compensation.
Pro Tools Reference Guide14
Pro Tools HD, Pro Tools LE, and Pro Tools M­Powered have different session file icons.
Pro Tools HD
Session file icons
Although there are different session file icons, the session files may be opened by all three ap­plications (with certain restrictions). See “Open­ing a Session” on page 51.
Pro Tools LE
Pro Tools M-Powered
When a session is transferred to a different Pro Tools system, its session file icon will change to the icon type of the destination system.

Tracks

Pro Tools tracks are where audio, MIDI, and au­tomation data are recorded and edited. Pro Tools tracks also provide audio channels for routing internal busses, and physical inputs and outputs for audio and MIDI.
Pro Tools provides seven types of tracks: audio tracks, Auxiliary Inputs, Master Faders, VCA Masters, MIDI tracks, Instruments tracks, and video tracks.
Audio track in the Edit window (stereo track shown)
Video tracks support both QuickTime movies and Avid video, but an individual video track can play back only one of these types of video at a time.
Audio, Auxiliary Input, Master Fader, VCA Mas­ter (Pro Tools HD only), and Instrument tracks can be mono, stereo, or multichannel (Pro Tools HD only). When creating a new track, you can choose from a list of formats sup­ported by your system.

Audio File

When you record audio into a Pro Tools session, audio files are created.
Audio file icon
MIDI track in the Edit window
Audio, MIDI, and Instrument track data can be edited into regions or repeated in different loca­tions to create loops, re-arrange sections or en­tire songs, or to assemble tracks using material from multiple takes.
Auxiliary Input tracks can route internal audio busses or physical inputs to internal busses or physical outputs. Auxiliary Inputs are typically used for audio effects busses, audio throughput, and submixing.
Master Fader tracks provide controls for physical audio output channels, including the volume level of your mix, panning, and plug-in inserts.
VCA Masters (Pro Tools HD only) provide con­trol of tracks in a Mix Group that has been as­signed to the VCA Master.
Audio files for each session are stored in a folder named “Audio Files.” Audio files are listed in the Pro Tools Region List and can appear in an au­dio track. A section of an audio file can be de­fined as a region. See “Regions” on page 15.

Regions

Audio region
A region is a segment of audio or MIDI data. A re- gion could be a drum loop, a guitar riff, a verse of a song, a recording take, a sound effect, some dialog, or an entire sound file. A region can also have associated automation data. In Pro Tools, regions are created from audio or MIDI files, and can be arranged in audio and MIDI track play­lists. Regions can also be grouped and looped.
Chapter 3: Pro Tools Concepts 15

Playlist

A playlist can be made up of a single region or many separate regions. It can be made up of similar elements, such as regions from several different takes of a solo, or dissimilar elements, such as several sound effects.
You can create any number of alternate edit playlists for a track. This lets you assemble dif­ferent versions of performances or edits on a sin­gle track and choose between them from a pop­up menu on the track.
Playlist selector pop-up menu
A playlist is a sequence of regions arranged on an audio or MIDI track. Tracks have edit playlists and automation playlists.
On audio tracks, an edit playlist tells the hard disk which audio regions to play in what order. For example, you can use the same audio region to access the same piece of audio multiple times at different locations and not use additional disk space. Different versions of the same original au­dio can be used in different places and have dif­ferent effects applied. On MIDI and Instrument tracks, edit playlists can store multiple MIDI se­quences (or performances) on a track.

Each track also has a single set of automation playlists, for volume, pan, mute, and each auto­mation-enabled control for the insert and send assignments on that track.

Channel

The term channel is used to describe several re­lated components of a Pro Tools system. The first example of channel refers to a physical in­put or output of your Pro Tools system.
For example, a 96 I/O audio interface (Figure 1) provides up to 16 channels of input and output to a Pro Tools|HD system, while an Mbox 2 au­dio interface provides up to four inputs and two outputs
Figure 1. Back view of 96 I/O, with eight analog inputs, eight analog outputs, and eight digital input/output channels (using a lightpipe)
Pro Tools Reference Guide16
The second use of the term channel refers to a channel strip in the Pro Tools Mix window. Each track in a Pro Tools session has a corre­sponding channel strip in the Mix window.
Audio and MIDI channel strips have similar controls, but those controls have slightly differ­ent effects. For example, audio and Auxiliary In­put channel strip faders control the output gain to the mix bus for that channel, while MIDI channel strip faders send MIDI volume data (MIDI controller 7) to the MIDI instrument. In­strument track channel strips combine a MIDI track and Auxiliary Input into a single channel strip.

Signal Routing

Pro Tools provides software-based mixing and signal routing controls. The Mix window is where these controls are located. (Some of these controls can also be accessed from the Edit win­dow.)
A common signal routing task is to submix mul­tiple tracks to a single channel strip (such as an Auxiliary Input or a Master Fader) for shared processing and level control. The following ex­ample shows three audio tracks submixed to a stereo Auxiliary Input.

Outputs to stereo bus path

The term channel also describes a separate aspect of MIDI operation. See “MIDI Con­cepts” on page 20.

Chapter 3: Pro Tools Concepts 17

Signal Routing Options
Signal routing options include the following:
Track Input and Output (I/O) Controls The most basic type of signal routing is track input and output. A track needs to have an assigned input path to record audio, and an assigned output path in order to be audible through a hardware output. Signals can also be routed to or from other tracks in Pro Tools (or hardware inputs and outputs) using internal busses.
Auxiliary Inputs and Master Faders Auxiliary In­puts are tracks that can be used as returns, sub­mixers, and bus masters. Master Faders are used as bus and output master level controls. Both Auxiliary Inputs and Master Faders can have plug-in and hardware inserts.
Instrument Tracks Instrument tracks let you route sound from a plug-in instrument to out­puts, sends and busses, or other inserts.
Sends Sends route audio from tracks to hard­ware outputs, or to internal busses that are in turn routed to other tracks within Pro Tools. Master Faders and VCA Masters do not have sends.
Plug-in and Hardware Inserts Plug-in processing occurs completely within the Pro Tools system. Hardware inserts utilize audio interface inputs and outputs, for traditional insert routing to and from external effects and other devices.
Paths Paths are any routing option in Pro Tools, including internal or external inputs, outputs, busses, and inserts. Pro Tools lets you name these paths, and these path names appear in the Audio Input and Output Path selectors and other menus. See Chapter 7, “I/O Setup” for more information.
Mixing Formats Sessions can include combina­tions of mono, stereo, and multichannel format tracks, busses, inputs, outputs, and inserts. (Multichannel formats are supported on Pro Tools|HD systems only.)

System Resources

Track count, plug-in processing, signal path and routing options, and voice availability are ulti­mately limited by the combined resources avail­able from the host computer, and from your Pro Tools hardware.
Pro Tools provides several ways to manage and conserve resources to maximize the perfor­mance of your system. As you begin working with Pro Tools sessions and tracks, you can take advantage of the following features to extend the effectiveness of your available DSP and other resources:
Pro Tools lets you adjust the performance of
your system by changing system settings that af­fect its capacity for processing, playback, and re­cording. See “Configuring Pro Tools System Settings (in the Playback Engine)” on page 41.
In order to free up needed DSP resources,
Pro Tools allows for certain items (such as tracks and inserts) to be manually made inactive. Inac­tive elements are viewable, editable, and re­tained within the session. See “Active and Inactive Items” on page 19.
All Pro Tools systems provide flexible voice
options for audio tracks, to help maximize use of available voices in your system. For more in­formation on voice management and options, see “Voice Borrowing” on page 115.
Pro Tools Reference Guide18

Active and Inactive Items

Pro Tools lets you make certain items (such as tracks and inserts) inactive, in order to free up DSP resources and mixer connections.
Items in Pro Tools that can be made inactive (or active) include the following:
• Audio, Auxiliary Input, Master Fader, VCA Master, and Instrument tracks
• Track Inputs and Outputs
• Sends
• Side-chain inputs
• Plug-ins
• Hardware inserts
• Paths (session-wide)
MIDI tracks cannot be made inactive.
In addition to manually setting Active and Inac­tive modes, Pro Tools automatically makes items inactive if there are insufficient or un­available resources.
Tracks When a track is made inactive, its voices become available for another track. Mono inac­tive tracks free up one voice; stereo and multi­channel tracks free up one voice per channel. Additionally, when an audio, Auxiliary Input, Instrument, or Master Fader track is made inac­tive, its plug-ins, inserts, sends, and I/O assign­ments become inactive, and the associated DSP used is freed up for use elsewhere in the session.
Display of Inactive Items
When items are inactive, their names appear in italics, and their background becomes dark grey. When a track is inactive, the entire channel strip is grayed out.
Active Inactive plug-in
When active, items are fully engaged and opera­tional.
When inactive, items are silent and off, although most associated controls can still be adjusted. Different inactive items affect available system resources in specific ways, as follows:
Plug-ins When a plug-in is inactive on a track, its DSP is made available for other plug-ins and processing. Plug-in assignments can be made in­active manually, or automatically (see “Auto­matic and Manual Inactive Mode” on page 20).
Paths and Path Assignments When a path or path assignment is inactive, its mixer resources are made available for other signal routing pur­poses in the session. Paths and assignments can be made inactive manually, or automatically (see “Automatic and Manual Inactive Mode” on page 20).
Inactive track
Active and inactive items and tracks
Chapter 3: Pro Tools Concepts 19
Automatic and Manual Inactive Mode
Active and Inactive modes are powerful options for session transfer and system resource man­agement. Pro Tools provides automatic and manual Inactive mode switching. You can man­ually make items inactive (or active) to selec­tively manage system resources while editing and mixing.
You can apply Active or Inactive modes to all or all selected tracks using standard Pro Tools mod­ifiers (Alt and Alt+Shift in Windows, Option and Option+Shift on the Mac).
Side-chain inputs support direct active and inac­tive switching, but do not follow switching all or all selected side-chain inputs.
Automatically Inactive Items
When opening a session, it is possible that not all signal paths, plug-ins, or audio interfaces used in the session will be available as defined on the current system. When opening a session, sufficient voices may also be unavailable if the session was created on a different Pro Tools sys­tem type (for example, opening a session cre­ated on a Pro Tools HD system on a Pro Tools LE system).
Whenever this occurs, the session will open as it was last saved. All items that are unavailable, or cannot be loaded due to insufficient resources, are made inactive.
Manual Inactive Switching
You can manually apply Active or Inactive modes to manage system resources. By making an item inactive, its associated resources are made available elsewhere in the session.
The following are basic instructions for manu­ally making items inactive. Throughout the Pro Tools Reference Guide, instructions are pro­vided whenever an item can be made inactive.

MIDI Concepts

MIDI (Musical Instrument Digital Interface) is a communication protocol for musical instru­ments. This industry standard enables connec­tions between a variety of devices from different manufacturers. Examples of MIDI-compatible equipment include synthesizers, sound mod­ules, drum machines, patch bays, effects proces­sors, MIDI interfaces, MIDI control surfaces, and sequencers.
MIDI devices are equipped with 5-pin DIN con­nectors, labeled as either IN, OUT, or THRU. The MIDI OUT port transmits messages. The MIDI IN port receives messages. The MIDI THRU ech­oes whatever is received from the IN port. MIDI devices are connected with MIDI cables that are available at most music stores.
echoed from IN
To toggle an item active or inactive:
Control-Start-click (Windows) or Command-
Control-click (Mac) the item.
Pro Tools Reference Guide20
MIDI signal flow
Not all devices will have all three MIDI ports (IN, OUT, and THRU).
The MIDI protocol provides 16-channels of MIDI per port. A single MIDI cable can transmit a separate set of messages for each of the 16 channels. These 16 channels correspond to sep­arate MIDI devices or to multiple channels within a single device (if the device is multi-tim- bral). Each channel can control a different in­strument sound. For example, bass on channel 1, piano on channel 2, and drums on channel 10. Similar to a multitrack tape re­corder, a MIDI sequencer can record complex ar­rangements—even using a single multi-timbral keyboard.

MIDI Terms

The following are some basic MIDI terms:
MIDI Instrument A hardware MIDI device or soft­ware plug-in (such as a virtual synth or instru­ment plug-in). In this guide, “instrument” usu­ally refers to soft synths and plug-in instruments.
MIDI Interface Hardware that lets computers connect to and communicate with MIDI de­vices.
MIDI Device Any keyboard, sound module, ef­fects device, or other equipment that can send or receive MIDI information.
MIDI Controller Any MIDI device that transmits MIDI performance data. These include key­boards, MIDI guitar controllers, MIDI wind in­struments, and others. Controllers transmit MIDI from their MIDI OUT ports.
MIDI Control Surface Any device (such as the Digidesign Command|8), which uses a MIDI connection to send control messages to a soft­ware program, but is not generally used to record MIDI information.
MIDI Tone Generator (MIDI Sound Source) Any MIDI device capable of playing back MIDI-trig­gered sound. Sound sources receive MIDI from their MIDI IN ports.
Multi-Timbral The ability of one MIDI device to play several different instrument sounds (such as piano, bass, and drums) simultaneously on separate MIDI channels. This makes it possible for a single multi-timbral MIDI instrument to play back entire arrangements.
MIDI Channel Up to 16 channels of MIDI perfor­mance data can be transmitted on a single MIDI cable. The channel number separates the differ­ent messages so your sound sources can receive the right ones.
Program Change Event A MIDI command that tells a sound source which of its sounds (or sound patches) to use. The MIDI protocol lets you choose from a range of 128 patches.
Bank Select Message Many devices have more than 128 patches, which are arranged in banks. The Bank Select Message is a MIDI command that specifies the bank of patches from which to choose.
Local Control A controller setting found on most MIDI keyboards that lets them play their own sound source. Disabling “local control” ensures that a device’s internal sound source is only played by external MIDI messages (such as those sent from Pro Tools when MIDI in Pro Tools is routed to the MIDI keyboard). When using Pro Tools, “local control” should usually be dis­abled. When “local control” is off, your key­board still transmits data to its MIDI OUT port.
Continuous Controller Events MIDI instructions that allow real-time changes to notes that are currently sounding. These include pitch bend, modulation, volume, pan, and many others.
Chapter 3: Pro Tools Concepts 21
System Exclusive Data MIDI data commonly used for sending and retrieving patch parameter information for storage purposes.
To actually hear an external MIDI instrument, you need to connect its audio outputs to a mix­ing console or connect it to one of the audio in­puts of your Pro Tools audio interface.

Common MIDI Misconceptions

MIDI is not audio, and by itself makes no sound. MIDI is control information only. It is like the piano roll for a player piano; it provides control information for what note to play when, for how long, and at what volume. For example, when you strike a key on a MIDI keyboard, it sends a message to a MIDI instrument or tone generator to play that particular note at that particular velocity. This could be its internal tone generator, an external MIDI instrument, or an instrument plug-in, which can be contained completely within Pro Tools. In order to create or play a MIDI recording, you must have a MIDI instrument. Audio from your instrument can be sent to an external mixer or monitored through your Pro Tools audio interface.
If you are using an external MIDI instrument, it must be connected to MIDI ports that are recog­nized by your computer. These ports can be on a Pro Tools interface that has MIDI ports (such as MIDI I/O, Mbox 2, or a Digidesign-qualified M­Audio interface) or some other MIDI interface.
Just as each Pro Tools system has unique hard­ware features, each MIDI device has its own fea­tures (and limitations) as to the number of voices and instruments it can play at one time. Consult the device’s documentation for infor­mation on its capabilities.
When using MIDI with instrument plug-ins in Pro Tools, virtual MIDI nodes. These nodes act like virtual MIDI ports and provide software MIDI connections between Pro Tools and other MIDI software, such as instrument plug-ins. For example, when you insert Propellerhead’s Rea­son as a ReWire client on a track, its various MIDI inputs to Reason become available to Pro Tools MIDI and Instrument track MIDI out­puts.

Chapter 6: Sessions

This chapter covers the basics of starting a project in Pro Tools, including how to set up and save a Pro Tools session.

Starting Up or Shutting Down Your System

To ensure that the components of your Pro Tools system communicate properly with each other, you need to start them in a particu­lar order.
Start up your Pro Tools system in this order:
1 For Pro Tools|HD systems with an expansion
chassis, turn on the chassis.
2 Turn on any external hard drives. Wait ap-
proximately ten seconds for them to spin up to speed.
3 Turn on any MIDI interfaces, MIDI devices, or
synchronization peripherals.
4 Lower the volume of all output devices in
your system.
5 For Pro Tools|HD systems, turn on your
Pro Tools audio interfaces. Wait at least fifteen seconds for your system hardware to initialize.
6 Turn on your computer.
7 Launch Pro Tools or any third-party audio or
MIDI applications.
Shut down your Pro Tools system in this order:
1 Quit Pro Tools and any other running applica-
tions.
• To quit Pro Tools, choose File > Exit (Win­dows) or Pro Tools > Quit (Mac)
2 Turn off or lower the volume of all output de-
vices in your system.
3 Turn off your computer.
4 For Pro Tools|HD systems, turn off audio inter-
faces.
5 For Pro Tools|HD systems with an expansion
chassis, turn off the chassis.
6 Turn off any MIDI interfaces, MIDI devices, or
synchronization peripherals.
7 Turn off any external hard drives.
Configuring Pro Tools System Settings (in the Playback Engine)
Pro Tools allows you to adjust the performance of your system by changing system settings that affect its capacity for processing, playback, and recording.
These system settings are changed in the Play­back Engine Dialog (Setup > Playback Engine).
Chapter 6: Sessions 41
In most cases, the default settings for your sys­tem provide optimum performance, but you may want to adjust them to accommodate large or processing-intensive Pro Tools sessions.

Hardware Buffer Size

The Hardware Buffer Size (H/W Buffer Size) con­trols the size of the hardware cache used to han­dle host-based tasks such as Real-Time Audio­Suite (RTAS) plug-in processing.
Lower Hardware Buffer Size settings reduce
monitoring latency, and are useful when you are recording live input.
Higher Hardware Buffer Size settings allow for
more audio processing and effects, and are use­ful when you are mixing and using more RTAS plug-ins.
In addition to causing slower screen re­sponse and monitoring latency, higher Hardware Buffer Size settings can affect the accuracy of plug-in automation, mute data, and timing for MIDI tracks.
To change the Hardware Buffer Size:
1 Choose Setup > Playback Engine.
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
bination with the CPU Usage Limit setting, the RTAS Processors setting lets you control the way RTAS processing and other Pro Tools tasks are carried out by the system.
For example:
• For sessions with large numbers of RTAS plug­ins you can allocate 2 or more processors to RTAS and set a high CPU Usage Limit.
• In sessions with few RTAS plug-ins, you can al­locate fewer processors to RTAS and set a low CPU Usage Limit to leave more CPU resources available for automation accuracy, screen re­sponse, or video.
• Increase or decrease these settings to accom­modate TDM/RTAS plug-in conversion. TDM/RTAS conversion can be desirable dur­ing recording, depending on the latencies, voicing needs, and record-monitoring capa­bilities of TDM and RTAS plug-ins.
• Depending on the importance of video and overall screen response, and on the density of automation being employed, different combi­nations of RTAS Processing and CPU Usage Limit settings may achieve the best results. For example, to improve screen response in a medium-sized session using a moderate num­ber of RTAS plug-ins, try reducing the number of RTAS processors but keep the CPU Usage Limit set to the maximum (99%) on a single processor system.

RTAS Processors

The RTAS Processors setting determines the number of processors in your computer allo­cated for RTAS (real-time plug-ins) plug-in pro­cessing.
With computers that have multiple processors, or that feature multi-core processing or hyper­threading, this setting lets you enable multi-pro­cessor support for RTAS processes. Used in com-
Pro Tools Reference Guide42
The System Usage window shows the combined amount of RTAS processing occurring on all en­abled processors with a single indicator, regard­less of how many CPUs are in the system. If the System Usage Window shows that you are at the limit of available resources, increase the number of RTAS processors and/or the CPU Usage Limit setting. (For more information, see “System Us­age” on page 59.)
To set the number of RTAS Processors:
1 Choose Setup > Playback Engine.
Playback Engine dialog
2 From the RTAS Processing pop-up menu, se-
lect the number of available processors you want to allocate. The number of processors available varies depending on how many pro­cessors are available on your computer:
• Choose 1 Processor to limit RTAS process­ing to one CPU in the system.
• Choose 2 Processors to enable load balanc­ing across two available processors.
• On systems running four or more proces­sors, choose the desired number of RTAS processors as needed.
Higher CPU Usage Limit settings allocate
more processing power to Pro Tools, and are useful for playing back large sessions or using more real-time plug-ins.
The maximum CPU Usage Limit is 85 percent for single-processor computers (except for Digi 002, which has a limit of 99 percent), and 99 percent for multi-process computers. (The 99 percent setting dedicates one entire processor to Pro Tools.
On multi-processor computers, the maximum CPU Usage Limit is reduced when you use all your processors (as selected in the RTAS Process­ing pop-up menu). For example, on dual-proces­sors, the limit will be 90%. On four-processor computers, the limit will be 95%.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
To change the CPU Usage Limit:
1 Choose Setup > Playback Engine.
2 From the CPU Usage Limit pop-up menu, se-
lect the percentage of CPU processing you want to allocate to Pro Tools.
3 Click OK.

CPU Usage Limit

The CPU Usage Limit controls the percentage of CPU resources allocated to Pro Tools host pro­cessing tasks. Used in combination with the RTAS Processors setting, the CPU Usage Limit setting lets you control the way Pro Tools tasks are carried out by the system.
Lower CPU Usage Limit settings limit the ef-
fect of Pro Tools processing on other CPU-inten­sive tasks, such as screen redraws, and are useful when you are experiencing slow system re­sponse, or when running other applications at the same time as Pro Tools.
3 Click OK.

Number of Voices

(Pro Tools HD Only)
On Pro Tools|HD systems, the Number of Voices setting lets you control the number of available voices and how those voices are allocated to DSPs in your system. For example, the default number of voices on a Pro Tools|HD 1 system is 48 voices, using one DSP (at sample rates of
44.1 kHz or 48 kHz).
Changing the number of voices affects DSP usage, the total number of voiceable tracks, and overall system performance.
Chapter 6: Sessions 43
Depending on the current sample rate and the number of Pro Tools|HD cards in your system, you will have different choices for voice count. For voice limits on different Pro Tools|HD sys­tems, see “Pro Tools|HD System Playback, Re­cording and Voice Limits” on page 7.

Default Sample Rate

The Sample Rate setting appears as the default sample rate when you create a new session. (This setting is available only when there is no session open.)
To change the number of voices and DSP to allocate for voicing:
1 Choose Setup > Playback Engine.
Playback Engine dialog
2 Select the number of voices and DSPs to allo-
cate for voicing by selecting a value from the Number of Voices pop-up menu.
• Select higher voice numbers when your Pro Tools|HD cards are the only PCI cards in your computer, or when you are using an expansion chassis to run higher track counts.
• Select medium voice numbers when your Pro Tools|HD cards are in an expansion chassis, or when you are using other PCI cards along with Pro Tools|HD cards.
• Select minimum voice numbers if you are using high-bandwidth PCI cards (such as video capture cards) along with your Pro Tools|HD cards. In addition, to free up DSP for plug-ins and processing, select the minimum number of voices and DSPs needed to play back the current session.
With Pro Tools HD, the Sample Rate set­ting can affect the number of available voices.
To change the default Sample Rate:
1 Choose Setup > Playback Engine.
2 Select the sample rate from the Sample Rate
pop-up menu.
3 Click OK.
You can change the sample rate when cre­ating a new Pro Tools session by selecting a different sample rate in the New Session di­alog. (
See “Creating a New Session” on
page 49.)

Delay Compensation Engine

(Pro Tools HD Only)
The Delay Compensation Engine lets you man­age DSP delays in the Pro Tools mixer.
There are three settings in the Playback Engine dialog for dedicating DSP resources for Delay Compensation:
None Allocates no DSP resources for Delay Com­pensation.
Short Allocates minimal DSP resources for Delay Compensation for each channel. This is the most efficient setting for Pro Tools|HD Accel systems.
3 Click OK.
Pro Tools Reference Guide44
Long Allocates maximum DSP resources for De­lay Compensation for each channel. Long Delay Compensation uses the SRAM contained on DSPs needed by DSP-intensive plug-ins.
To configure the Delay Compensation Engine:
1 Choose Setup > Playback Engine.
2 From the Delay Compensation Engine pop-up
menu, select a Delay compensation setting.
3 Click OK.
The Delay Compensation setting is saved as a session and system preference.
For more information, see “Delay Compen­sation” on page 553.

DAE Playback Buffer Size

The DAE Playback Buffer Size determines the amount of memory DAE allocates for disk buff­ers. The optimum DAE Playback Buffer Size for most disk operations is Level 2.
DAE Playback Buffer Size settings lower than
Level 2 may improve playback and recording initiation speed, but may make it difficult to play or record tracks reliably with sessions con­taining a large number of tracks or a high den­sity of edits, or running on slower or heavily fragmented hard drives.
DAE Playback Buffer Size settings higher than
Level 2 will allow for a higher density of edits in a session or a higher track count when using slower hard drives. However, a higher setting can also cause a time lag to occur when starting playback or recording, and result in a longer au­dible time lag while editing during playback.
Using a larger DAE Playback Buffer Size leaves less system memory for other tasks. The default setting of Level 2 is recom­mended unless you are encountering -9073 (“Disk too slow or fragmented”) errors.
To change the DAE Playback Buffer Size:
1 Choose Setup > Playback Engine.
Playback Engine dialog
2 From the DAE Playback Buffer pop-up menu,
select a buffer size. Memory requirements for each setting are shown at the bottom of the Playback Engine dialog.
3 Click OK.
4 If Pro Tools needs more system memory for
the DAE Playback Buffer, it will prompt you to restart your computer.

System Memory Allocation

(Pro Tools HD Only)
When you start your computer, Pro Tools auto­matically reserves a portion of system memory for the DAE Playback Buffer. This reserved mem­ory is unavailable to other applications, even if Pro Tools is not running.
You can set Pro Tools to reserve only the mini­mum amount of required memory, so that sys­tem memory is available to other applications.
Chapter 6: Sessions 45
To minimize system memory allocation:
1 Choose Setup > Playback Engine.
2 Select the “Minimize System Memory Alloca-
tion” option.
3 Click OK.
4 Do one of the following:
• On Windows systems, restart your com­puter.
– or –
• On Mac systems, enter your password when prompted, then restart your com­puter.
Configuring Pro Tools Hardware Settings
96 I/O can have additional interfaces attached (including older Digidesign audio interfaces, or Legacy I/Os, such as the 888|24 I/O, 882|20 I/O or 1622 I/O). For more information, see Chapter 2, “Pro Tools System Configurations.”
Configuring Hardware Setup
The Main page of the Hardware Setup dialog is where you define which physical inputs and outputs on your audio interface are routed to available inputs and outputs in Pro Tools.
Pro Tools allows you to configure the signal routing, digital I/O format, default sample rate, clock source, and other hardware-based settings depending on your system configuration.
The following section outlines the configura­tion of a Pro Tools|HD system with one or more Pro Tools|HD interfaces (with one or more Leg­acy interfaces attached).
To configure a Pro Tools LE system, refer to the
Getting Started Guide that came with
that system.
Configuring Pro Tools|HD Hardware
On Pro Tools|HD systems, you configure Hard­ware settings for each audio interface connected to your system. For example, Pro Tools|HD sys­tems can have 192 I/O, 192 Digital I/O, 96 I/O, or 96i I/O audio interfaces connected to HD Core and HD Accel or HD Process cards in the system. The 192 I/O, 192 Digital I/O, and
Hardware Setup dialog for 96 I/O (Main page)
Additional pages are available to configure other controls for each audio interface (such as setting operating levels). For details, refer to the Getting Started Guide for your system, or to the guide for your audio interface.
You can identify audio interface connec­tions at any time by selecting the interface name in the Peripherals list, then clicking Identify. All the LEDs on the interface front panel will illuminate.
To configure audio interfaces on a Pro Tools|HD system:
1 Choose Setup > Hardware.

audio interface connected to the first card in your system. This will be the interface at the top of the list.
3 Click the Main tab.
Pro Tools Reference Guide46
4 From the Clock Source pop-up menu, select
the appropriate clock source for the system. In many cases, you will use Internal. The other choices are for resolving Pro Tools to external clock sources. Depending on your audio inter­face, Clock Source options can include: AES/EBU [Encl], S/PDIF, Optical [Encl], AES/EBU 1–8, TDIF, ADAT, and Word Clock (optional Word Clock rates are available when operating at higher sample rates).
5 From the Ext. Clock Output pop-up menu, se-
lect the appropriate clock output to send to de­vices attached to your audio interface.
6 Select which digital I/O port on your audio in-
terface enclosure is active under Digital Format. Choices include: AES/EBU, S/PDIF, and Optical (S/PDIF). Selecting Optical (S/PDIF) resets the Optical I/O port (which is, by default, eight channels of ADAT I/O) to two channels of S/PDIF Optical I/O.
7 For S/PDIF compatibility with Tascam DA-30
DAT recorders select the Tascam option under S/PDIF Format.
8 For the 96 I/O, click the Meters pop-up menu
and select whether to meter the input or output signal.
9 From the Input and Output pop-up menus, se-
lect the physical ports (such as Analog 1–2 or Optical 1–2), that will be routed to the corre­sponding Pro Tools input and output channels (such as Ch 1–2 or Ch 3–4), listed on the left side of the Main page.
Inputs and outputs of similar format are differ­entiated in the input and output channel pop­up menus. For example, the AES/EBU inputs and outputs in the 192 I/O enclosure are listed as AES/EBU [Encl], while the AES/EBU inputs and outputs on the factory-installed Digital I/O card are listed (in pairs) as AES/EBU 1–2, AES/EBU 3–4, AES/EBU 5–6, and AES/EBU 7–8.
For 192 I/Os equipped with the optional Digital I/O Card, the additional AES/EBU I/O ports on the optional card are listed as AES/EBU 9–10, AES/EBU 11–12, AES/EBU 13–14, and AES/EBU 15–16.
10 Click other tabs (such as Analog In and Ana-
log Out) for additional configuration options specific to the audio interface. These include:
• On the 96 I/O, configuring the operating levels of analog inputs and outputs (+4 dBu or –10 dBV).
• On the 96i I/O, configuring the operating levels of analog inputs and outputs (+4 dBu or –10 dBV).
• On the 192 I/O analog input, setting the input connector and Soft Limit
• On the 192 I/O, configuring the two sets of trims for analog inputs and outputs.
• On the 192 I/O and 192 Digital I/O, config­uring real-time Sample Rate Conversion for digital inputs.
• On the 192 I/O and 192 I/O Digital, config­uring inputs and outputs on any optional A/D card, D/A card, or Digital I/O cards in­stalled in the unit.

See “Initializing MIX-Series Legacy Peripher­als (on a Pro Tools|HD System)” on page 48.
8 Repeat the above steps for each additional
Legacy I/O.
For information on Hardware Setup controls for each Legacy audio interface, refer to the guide that came with the interface.
Configuring I/O Setup
13 Click OK.
Initializing MIX-Series Legacy Peripherals (on a Pro Tools|HD System)
Before you can configure a Legacy I/O, it must first be initialized in Hardware Setup.
To initialize a Legacy I/O on a Pro Tools|HD system:
1 Start up your Pro Tools system. See “Starting
Up or Shutting Down Your System” on page 41.
2 Make sure to lower the volume of your output
devices. Very loud digital noise may be emitted before the Legacy I/O is initialized.
3 Turn on your Legacy I/O.
4 From the Peripherals list, choose the primary
audio interface (the Pro Tools|HD interface to which your Legacy I/O is connected).
5 In the Main page of the Hardware Setup dia-
log, select the Legacy I/O option under Port Set­tings.
6 In the Peripherals list, “No Interface” is listed
twice, directly below the primary audio inter­face. Click the first “No Interface.” An Interface pop-up menu appears in the Hardware Setup di­alog, listing supported I/O choices.
7 From the Interface pop-up menu, select the
type of Legacy I/O you connected.
The I/O Setup dialog provides a graphical repre­sentation of the signal routing for each con­nected audio interface, with controls to route physical ports on the audio interface to Pro Tools inputs and outputs. These controls mirror the routing controls found in the Hard­ware Setup dialog—changes made to physical routing in one dialog are always reflected in the other.
The I/O Setup dialog lets you label and map Pro Tools input, output, insert, and bus signal paths. The I/O Setup dialog also provides impor­tant audition, meter, and surround settings. For more information, see Chapter 7, “I/O Setup.”
Routing a Pro Tools Output Pair to Multiple Destinations
Pro Tools channel pairs can be routed to multi­ple outputs on an audio interface through the Hardware Setup dialog. For example, if you as­sign both Analog 1–2 and Analog 3–4 interface outputs to Pro Tools Output pair 1–2, when you send a signal to Pro Tools Outputs 1–2, that sig­nal will be routed simultaneously to both pairs of output ports on your audio interface.
This lets you send the same signal (such as a ste­reo pair, a stem mix, or a multichannel mix) to multiple destinations (such as multiple master­ing devices).
The Main page updates with controls that can be configured.
Pro Tools Reference Guide48
To select multiple output ports for a Pro Tools output channel pair:
1 Choose Setup > Hardware.
2 From the Peripherals list, select an interface.

4 Select the bit depth (16 bit or 24 bit) and the
sample rate.
5 Select the I/O Settings to use for the session.
Several pre-configured I/O Settings are included with your system, or you can select a custom I/O Setting that you have created. See Chapter 7, “I/O Setup” for more information.
6 Name the Session.
7 Click Save.
Chapter 6: Sessions 49
Selecting Bit Depth and Sample Rate
Audio Files Folder
When selecting a bit depth or sample rate for your session, consider fidelity, any compatibil­ity issues with others systems, and storage space.
Bit depth and sample rate also have an effect on the amount of mixing power available in a ses­sion. Fewer mixer channels are available with 24-bit sessions and with sessions at higher sam­ple rates. (For more information, see the Pro Tools|HD Getting Started Guide.)
It is not possible to combine different bit depths within a single Pro Tools session; files of differ­ent bit depths must be converted and imported into the session.

Session Files and Folders

When you create a new session, Pro Tools auto­matically creates a new folder named for your session. Within this folder is the session file, a WaveCache.wfm file, and several subfolders (an Audio Files folder, a Fade Files folder, a Region Group folder, and a Session File Backups folder).
The Audio Files folder contains all audio re­corded or converted during the session.
When you record a new audio track, the track is saved as a new audio file to the Audio Files folder. You can also import other audio files into the session, and work with them as well.
For details on allocating audio tracks to different hard drive locations, including shared media volumes, see “Disk Allocation” on page 187.
Fade Files Folder
The Fade Files folder contains any crossfaded au­dio data generated by the session.
Region Groups Folder
The Region Groups folder is the default direc­tory for any region groups that you export from your Pro Tools session.
WaveCache File
The WaveCache.wfm file stores all of the wave­form display data for the session. If you delete the WaveCache.wfm file, Pro Tools will create a new one the next time you open the session.
Typical session folder contents
Session File
The session file is the document that Pro Tools creates when you start a new project. Pro Tools can open only one session file at a time. The ses­sion file is named with a .ptf (Pro Tools file) ex­tension.
Pro Tools Reference Guide50
By storing waveform data in the WaveCache file, sessions are able to open more quickly. The session WaveCache file can be included when­ever a session is transferred to another Pro Tools 7.x system.
Pro Tools also maintains a distinct WaveCache file inside the local Digidesign Databases folder (C:\\Digidesign Databases) which retains wave­form data for all files used on the system. Addi­tional WaveCache files are created on each ex­ternal hard drive attached to your system, and stored in the Digidesign Databases folder on each drive.
Deleting or trashing any of the WaveCache files will not harm the session or your system. Each session will merely need more time to open due to having to recalculate waveform data for asso­ciated audio (and store that data in a new Wave­Cache file).
Session File Backups Folder
The Session File Backups folder contains auto­matically-generated backups of your Pro Tools sessions. These files are created when working on a session and the Operations preference for Enable Session File Auto Backup is enabled. (See “Enable Session File Auto Backup” on page 64.)
To open an existing session:
1 Choose File > Open Session.
2 Locate the session you want to open and click
Open.
Renamed Audio Files Folder
This folder includes file names that have been renamed when you open a session that contains audio file names with incompatible characters, or, in certain situations, save a copy of a session to a Pro Tools version that does not support long file names.
For more information, see “Renamed Audio Files and the Renamed Audio Files Folder” on page 164.

Opening a Session

When you open a session, Pro Tools looks in the session folder for audio and fade files linked to the session.
For more information on opening sessions created on different platforms, Pro Tools systems, or Pro Tools software versions, see Chapter 10, “File and Session Management and Compatibility.”
Open Session dialog

Opening a Session that Contains Unavailable Files

The DigiBase feature will prompt you if files are located but reside on Transfer volumes (such as CD or DVD discs), or if any required files cannot be found. See “Locating Audio Files” on page 163 for more details.

Opening a Session from a Transfer Volume

When opening a session from a Transfer volume (such as a CD or DVD disc), the DigiBase feature will prompt you to save the session on a Perfor­mance volume, and copy and convert any refer­enced media files. See “Locating Audio Files” on page 163 for more details.
Chapter 6: Sessions 51

Opening a Session that Contains Unavailable Resources

Pro Tools prompts you when opening a session that contains unavailable voices, I/O paths, DSP resources, or plug-ins. This is common when transferring sessions to systems with different Digidesign hardware.
The Unavailable Resources dialog provides an initial report of the missing session compo­nents. To save a text (.txt) file containing a more detailed Notes report, along with the resulting action, click Yes. The Notes report will be named with the session name, followed by Notes.txt. You can choose to save this file in your Session folder, or in another location.
The following will occur when opening a ses­sion with unavailable items:
With all Pro Tools Systems:
Inserts assigned to unavailable plug-ins are
made inactive.
Inputs, outputs, and sends that are assigned to
unavailable paths are made inactive.

Opening a Session with Audio File Names that Contain Illegal Characters

Pro Tools 7.x does not support audio file names that contain the following ASCII characters:
/ (Forward Slash)
\ (Backslash)
: (Colon)
* (Asterisk)
? (Question mark)
“ (Quotation marks)
< (Less-than symbol)
> (Greater-than symbol)
| (vertical line or pipe)
Any “high order” ASCII character (created
with a key combination)
When opening sessions that contain audio files with illegal characters, Pro Tools automatically creates a renamed copy of each file (replacing these characters with an underscore “_”). Re­named files are copied to the Renamed Audio Files folder. The original files are left intact in the Audio Files folder.
With Pro Tools HD Only:
Any tracks beyond the maximum number of
available voices on the current system are made inactive.
With Pro Tools LE and M-Powered Only:
Any tracks beyond the maximum number of
available voices on the current system are set to voice off.
Pro Tools Reference Guide52
Before the session opens, you are prompted to save a detailed report of the renamed files and their original file names to a Notes text file. Fol­low the on-screen instructions. By default, the Notes text file is saved to the Session folder.

Opening a Session that Was Saved with +6 dB Fader Gain

All Pro Tools 7.x sessions have a +12 dB fader gain level. However, when saving a Pro Tools
7.x session to a lower version of Pro Tools that supports +6 dB and +12 dB fader gain, the new session can be saved with either a +6 dB or a +12 dB maximum fader gain.
When saving a +12 dB session as a +6 dB ses­sion, Pro Tools alerts you that any automation breakpoints over +6 dB will be lowered to +6 dB. See “Saving a Copy of the Session” on page 54.
In Pro Tools 7.x, when opening a session that was saved with a +6 dB maximum gain level, the session will update to a +12 dB range.

Saving the Session File with a New Name

To save a copy of the current session with a new name or to a different hard drive location, you can use the Save As command. Because the Save As command closes the current session and lets you keep working on the renamed copy, it is useful if you are experimenting and want to save successive versions of the session.

Saving a Session

You should save regularly while working on your session to ensure that your work is pre­served on your hard drive.

Saving the Session File

The Save command saves the changes you have made to your session and writes them over the previously saved version of the session file. The Save command cannot be undone.
To save a session:
Choose File > Save.
Revert to Saved Command
If you have made changes to a session since you last saved it, you can discard the changes and re­vert to its previously saved state.
To revert to the last saved version of a session:
Choose File > Revert to Saved.
By working this way, you can quickly retrace your steps if you want to go back to an earlier version of your session. The Save As command saves a new version of the session file only—not duplicate versions of the audio or fade files.
To save a session with a new name:
1 Choose File > Save As.
2 Enter a new name for your session.
Pro Tools 7.x lets you name files with as many characters as your operating system supports.
3 Click Save.
The renamed session file is saved in the session folder along with the original session (unless you specify a different destination). Any new audio files that you record in your renamed ses­sion will be placed into the same Audio Files folder that was created for your original session.
You can also open up a backup copy of your session, if you have enabled the Operation preference for Auto Backup. This feature lets you specify the total number of incre­mental backups that are kept and how often the session is saved. See “Auto Backup Sec­tion” on page 64.
Chapter 6: Sessions 53

Saving a Copy of the Session

To save a copy of the current session with or without its audio files and fade files, you can use the Save Copy In command. In addition, you can specify a session file format, audio file for­mat, bit depth, and sample rate for the session copy.
For information on sharing sessions be­tween different platforms, Pro Tools sys­tems, or Pro Tools software versions, see Chapter 10, “File and Session Management and Compatibility.”
Using the Save Copy In command is the only way to change the sample rate of a session.
When you save a copy of the session to a lower bit depth, Dither (and Noise Shaping) are ap­plied. See the following table:
Dither and Noise Shaping with Save Copy In
Session Bit Depth Dither
24-bit to 24-bit No No
16-bit to 24-bit No No
24-bit to 16-bit Yes Yes
16-bit to 16-bit No No
Noise Shaping
The Dither setting used for any conversion is the Digidesign Dither plug-in with Noise Shaping enabled.
For more information about using Dither, see “Dither” on page 557.
To save a session copy in a new location:
1 Choose File > Save Copy In.
Save Copy In dialog
Unlike the Save As command, Save Copy In does not close the original session, so subsequent ed­its are made to the original session. Session cop­ies can be used to archive important sessions, or as a means to prepare sessions for transfer to an­other Pro Tools system.
Save Copy In can save only the audio being used in the session. Any audio that was recorded or imported and then later removed from the ses­sion will not be included in the new session copy.
To include audio with the session copy, All Audio Files must be selected in the Items to Copy section.
Pro Tools Reference Guide54
2 In the Save Copy In dialog, choose a destina-
tion and enter a name for the new session file.
3 Choose a session file format for the copied ses-
sion.
4 Set the Audio File Type for the copied session.
If the audio files need to be compatible with ei­ther Windows or Mac, select BWF (.WAV) or AIFF.
5 Set the session Sample Rate and Bit Depth for
the copied session.
6 If applicable, select a Fader Gain level for the
copied session.
7 If applicable, select “Enforce Mac/PC Compat-
ibility” to create session and audio files that can be used on both Windows and Mac Pro Tools systems. See “Saving Copies of Mac Sessions to be Compatible with Windows” on page 168.
8 Select the Items to Copy for the copied ses-
sion.
Session Parameters
Audio File Type
You can save the session to reference BWF (.WAV) or AIFF audio files. On the Mac, you can also save the session to reference SD II audio files (at sample rates up to 48 kHz).
To include audio with the session copy, All Audio Files must be selected.
9 Click Save.
Session Format
You can save the session copy in the following formats, depending on your platform:
Windows:
• Pro Tools Session (.ptf); supports Pro Tools
7.x
• Pro Tools 5.1 -> 6.9 Session (.pts);
• Pro Tools 5.0 Session (.pt5)
• Pro Tools 4 24-Bit Session (.p24)
• Pro Tools 4 16-Bit Session (.pt4)
Mac:
• Latest; supports Pro Tools 7.x
• Pro Tools 5.1 -> 6.9 Session
• Pro Tools 5.0 Session
• Pro Tools 4 24-Bit Session
• Pro Tools 4 16-Bit Session
• Pro Tools 3.2 Session
When saving sessions to versions lower than
5.1, multichannel tracks (including stereo) and multi-mono plug-ins are lost. In this case, make sure to first separate the tracks and plug-ins to individual mono tracks.
SD II sessions are not supported with Pro Tools on Windows, or with sample rates higher than 48 kHz.
Using Mixed File Types
A session can use mixed audio file types. If your original session has mixed file types, they are not converted to a different file type unless you specify that they be converted. However, when using mixed file types, audio performance will be reduced (due to additional file handling re­quired for some file formats).
Bit Depth
You can save the new session at 16-bit or 24-bit depth. If your session is in a different bit depth, audio files are converted to the new session bit depth, and copied to the location you specify.
For information on bouncing to disk and dither, see “Dither and Bounce to Disk” on page 636.
Sample Rate
You can save the new session at sample rates of
44.1 kHz or 48 kHz (on Mbox 2 and Mbox) and at sample rates up to 96 kHz (on Digi 002, Digi 002 Rack and Pro Tools|HD systems with a 96 I/O or 96i I/O) or up to 192 kHz (on Pro Tools|HD systems with a 192 I/O or 192 Digital I/O). If your session is at a different sample rate, audio files are converted to the new session sample rate, and copied to the location you specify.
Chapter 6: Sessions 55
The higher the quality of sample rate conver­sion you choose, the longer Pro Tools will take to process the audio file.
Fader Gain
When saving a Pro Tools 7.x session to a lower version of Pro Tools that supports +6 dB and +12 dB fader gain, you can save the new session with either a +6 dB or a +12 dB maximum fader gain. When saving a +12 dB session as a +6 dB session, Pro Tools alerts you that any automa­tion breakpoints over +6 dB will be lowered to +6 dB.
Enforce Mac/PC Compatibility
When saving a Pro Tools 7.x session to a lower version of Pro Tools, this setting forces Windows or Mac versions of Pro Tools to create sessions and audio files that are usable on both plat­forms.
For more information, see “Saving Copies of Mac Sessions to be Compatible with Win­dows” on page 168.
Items to Copy
All Audio Files
When this option is selected, all audio files are copied to the new location.
This setting is automatically selected if you are changing the bit depth or sample rate of the ses­sion.
All “Non-Native” Audio Files
The name of this option varies depending on the audio file type you select. If you are chang­ing the audio file type of the session, this option ensures that all files in the copied session are converted to the selected file type. Use this op­tion to avoid the reduced performance of a ses­sion with mixed file types.
This option is automatically selected if you are changing bit depth or sample rate, or copying a session on the Mac from SD II format to AIFF or BWF (.WAV) format with Enforce Mac/PC Com­patibility selected.
Don’t Copy Fade Files
When this option is selected, Fade Files are not copied to the new session Fade Files folder.
Pro Tools opens the session with all available media, then shows you how many files are miss­ing (if any) and asks how you want to proceed. You can choose to locate the existing fades, us­ing Manually Find Relink or Automatically Find Relink, or choose to Skip All to let Pro Tools rec­reate the fades from the session document. You can also select Regenerate Missing Fades to ex­clude fade files from the relink process and re­generate them instead.
Session Plug-in Settings Folder
When this option is selected, the session’s Plug­in Settings folder is copied to the new location. The references to these plug-in settings in the session are redirected to the copied settings files.
Root Plug-in Settings Folder
When this option is selected, the contents of the root-level Plug-in Settings Folder are copied into a folder named Place in Root Settings Folder, indi­cating that these files will need to be moved to
Pro Tools Reference Guide56
the root level plug-in settings folder on the des­tination system before you can use them. The references to these settings files in the session are not redirected to point to the copied files.
Movie/Video Files
When this option is selected, session movie files (such as Avid or QuickTime video files) are cop­ied to the new location, and session references are updated to point to the copied movie files.
Preserve Folder Hierarchy (Pro Tools HD Only) When selected, the relative arrangement
of session audio files located across different drives or folders is maintained. The main folder for the session copy will include subfolders for each drive or folder in the original session and the destination subfolders will use the same names as the source drives and folders.
When this option is not selected, the Save Copy In command copies all files of the same type, re­gardless of their location, into a single destina­tion folder.
To create a custom session template in Windows:

Creating Custom Session Templates

You can create custom session documents that are pre-configured to the track setups, mixer set­ups, window arrangements, and zoom level Memory Locations that you use most fre­quently. Doing this will save you the trouble of having to create your studio setup from scratch every time you start a new session.

Creating Windows Templates

In Windows, you can create a session template by making a session file a Read Only document.
Making a session a Read Only file (Windows)
8 Click OK.
To use this template, double-click it or open it with the Open Session command. When you first save the session, Pro Tools will ask you to give the session a new name. Your original ses­sion template will remain unchanged.
To modify the session template, you will need to reopen its Properties, deselect the Read Only op­tion, make your modifications, then change it back to a Read Only file.
Chapter 6: Sessions 57

Creating Mac Templates

On the Mac, you can create a session template by saving a session file as a Stationery Pad docu­ment. Once a session is saved as a Stationery Pad, it acts as a template that you can open and then resave as a normal session.
To create a custom session template on the Mac:
1 Create a session and arrange its elements as
you want them to appear in the template. In ad­dition to track setup, you can also define ele­ments such as signal routings, insert and send configurations, Mix and Edit window views, ruler settings, and Preference settings.
10 Select the Locked option.
11 Close the information window.
To use this template, double-click it or open it with the Open Session command if you are al­ready running Pro Tools.
When you open a session saved as a Stationery Pad, Pro Tools gives you the option of editing the template or starting a new session using the template settings. If you choose New Session, Pro Tools will create a new folder containing a copy of your session template and Audio and Fades folders.
2 Choose File > Save As.
3 Name the session and click Save.
4 Close the session.
5 Locate the session file that you just saved.
6 Click once on the file to select it.
7 Choose File > Get Info.
Saving a session as a Stationery Pad (Mac)
8 If necessary, click the General expand/collapse
triangle to display the General information and options.
9 Select the Stationery Pad option.

Closing a Session

Because Pro Tools lets you work on just one ses­sion at a time, you must close the current ses­sion if you want to work on another. The Close Session command closes your current Pro Tools session but leaves the Pro Tools application open. You can save your work using the Save or Save As command before closing a session.
To close a session:
Choose File > Close Session.

Quitting Pro Tools

Although Pro Tools will warn you before allow­ing you to quit without saving changes, you should generally save your work before quitting.
To exit Pro Tools in Windows:
Choose File > Exit.
To quit Pro Tools on the Mac:
Choose Pro Tools > Quit Pro Tools.
Pro Tools Reference Guide58

System Usage

About Processing Bandwidth
Meters in the System Usage window indicate how much of your system’s processing power is being used in processing audio, and when writ­ing and playing back automation.
Pro Tools HD, LE, and M-Powered have three common meters, showing PCI bus activity, CPU processing activity, and Disk processing activity.
If CPU or PCI Activity are high, a system error may occur. If Disk Activity is high, Pro Tools may miss playback of some of your automation data during particularly dense periods of activ­ity, such as while using the Bounce to Disk com­mand.
To monitor the usage of resources during a Pro Tools session:
Choose Window > System Usage.
For more information, see “Bounce to Disk” on page 638.
System activity meters
System Usage window (Pro Tools LE shown)
With Pro Tools HD, there are addition meters, showing TDM Time Slot usage and DSP usage of each Pro Tools|HD system card.
System activity meters
TDM Time Slot usage
DSP usage
System Usage window (Pro Tools HD shown)
As these meters approach their limits, recording or playback of automation data may be affected.
To reduce processing load, try one of the following:
Reduce the density of automation in places
where it shows the most activity. For details, see “Thinning Automation” on page 604.
Turn off meters in Sends View, if enabled (by
disabling Show Meters in Sends View in the Dis­play Preferences page). For details, see “Individ­ual Send Views and Meters” on page 540.
System Usage Views
(Pro Tools HD Only)
With Pro Tools HD, there are five different Sys­tem Usage Views: Small, Large, Detailed, Gas Gauge, and Activity Only. The Detailed and Gas Gauge formats show the percentage of each DSP chip in use.
To change the System Usage View:
Choose View > System Usage, and one of the
System Usage View formats (such as Small).
For information on using different views to monitor DSP usage, see the Pro Tools|HD Getting Started Guide.
Chapter 6: Sessions 59

Preferences

The Preferences dialog has several tabbed pages in which you can specify your preferred settings for various session parameters. Each new session will use these preferences.

Display Preferences

Recompute Invalid Overviews Prompts Pro Tools to look for missing or corrupted overview data (the data used to create waveform displays) when it opens sessions. If Pro Tools finds that overview data is missing or corrupted, it will re­create one or more overviews for the session. This may take some time if there are many tracks in the session. If you suspect that over­view data for a session has become corrupted, or if you import audio files which have no over­view data into a session, make sure this prefer­ence is enabled for the session, save and close the session, then reopen it. Pro Tools will recre­ate any overviews for the session when it opens.
Track Position Numbers Stay with Hidden Tracks When selected, tracks keep their track
numbers even when hidden. When not se­lected, numbers are only assigned to tracks that are shown. In this case, shown tracks are then numbered sequentially, and hidden tracks are not numbered.
Basics Section
Draw Grids in Edit Window Adds grid lines to the Edit window. Grid line resolution is based on the zoom level of the Edit window.
Draw Waveforms Rectified Displays audio wave­form data in rectified view. In this view, audio waveforms are displayed so that their positive and negative waveform excursions (the portions that fall above and below the center line) are summed together and viewed as a single posi­tive-value signal. This view allows more wave­form detail to be seen in either normal or re­duced track height views. It can be particularly useful when editing volume automation data, since it depicts waveform levels as starting at the bottom of the track.
Pro Tools Reference Guide60
Tool Tips Display Options
Function Configures Tool Tips to show the basic
function of the item.
Details Configures Tool Tips to show the com­plete name of an abbreviated name or item. De­tails view can also show the hidden or abbrevi­ated value of parameters, as well as input and output assignments.
Edit Window Default Length
This preference sets a default length for the Edit window in hours, minutes, seconds, and frames (Pro Tools HD or Pro Tools LE with DV Toolkit 2 only). This is useful if you want to assemble a session of a particular length or leave extra room to expand the Edit window’s work area in your session. The maximum length is 12 hours and 25 seconds at 48 kHz, and proportionally less at higher sampling rates.
“Organize Plug-in Menus By” Options
Meters Section
These option customize how plug-in menus are organized in the Insert selector or Plug-in selec­tor.
Flat List Organizes plug-ins in a single list, in al­phabetical order.
Category Organizes plug-ins by process category (such as EQ, Dynamics, and Delay), with indi­vidual plug-ins listed in the category submenus. Plug-ins that do not fit into a standard category (such as the DigiRack Signal Generator), or third-party plug-ins that have not had a cate­gory designated by their developers, appear in the Other category. Plug-ins can appear in more than one category.
Manufacturer Organizes plug-ins by their manu­facturer (such as Digidesign, Eventide, Line 6, and McDSP), with individual plug-ins listed in the manufacturer submenus. Plug-ins that do not have a Manufacturer defined will appear in the “Other” manufacturer folder.
Most Digidesign-distributed third party plug-ins will be grouped under Digidesign when Manu­facturer view is enabled.
Peak Hold Options
These options determine how long the peak in­dicators on track meters stay lit after a peak is detected.
3 Second Peak Hold When selected, track meters display the last peak level for three seconds.
Infinite Peak Hold When selected, track meters display the last peak level until you click them to clear them.
No Peak Hold When selected, track meters do not hold the peak level.
Clip Indication Options
These options determine how long the clip indi­cators on plug-in, send, and track meters stay lit after a clip is detected.
3 Second Clip Hold When selected, meters dis­play the last clip indication for three seconds.
Infinite Clip Hold When selected, meters display the last clip indications until you click them to clear them.
Category and Manufacturer Organizes plug-ins in two levels of menus. The top menus display plug-ins by process category (such as EQ, Dy­namics, and Delay), with individual plug-ins listed in the category submenus. The bottom menus display plug-ins by manufacturer (such as Digidesign, Eventide, Line 6, or McDSP), with individual plug-ins listed in the manufacturer submenus.
No Clip Hold When selected, meters do not hold the clip indication.
Show Meters in Sends View
When the Sends View is displaying individual send controls, you can select this option to show send level meters. Deselecting this option can help speed up screen redraws and process­ing.

playback speeds are available in both forward and reverse. You can also recall Memory Loca­tions by typing Period (.), the Memory Location number, and Period (.) again.
Video Section
QuickTime Playback Priority Options
Normal This is the default setting for QuickTime
Movie Playback Priority. It gives no extra prior­ity to movie playback over other screen update tasks such as metering, moving faders, and so on. In most cases you should use this setting.
Medium This setting gives QuickTime movie playback a higher priority relative to other Pro Tools screen update tasks. Use this setting if you experience inconsistent QuickTime movie playback with the Normal setting.
Highest This setting gives QuickTime movie playback highest priority. In this mode, Pro Tools disables screen activity and requires you to use the Spacebar to stop playback. Use this setting if you require uninterrupted Quick­Time movie playback.
Avid Video Errors Stop Playback
(Pro Tools HD Only)
When selected, Pro Tools automatically stops playback of audio and video if a single frame of video is dropped.
When not selected, Pro Tools continues play­back of audio even if frames are dropped. In most cases, video playback will recover within a few frames and continue playing audio and video in sync.
Avid Video NTSC Has Setup (NTSC-J)
(Pro Tools HD Only)
This preference lets you adjust the level of NTSC video black output between 7.5 IRE (standard) or 0 IRE. When this option is selected, output level is 0 IRE.
Auto Backup Section
Enable Session File Auto Backup When selected, Pro Tools automatically saves backups of your Pro Tools session file while you work. Backups are saved to in the Session Files Backup folder in your session folder.
Keep specifies the total number of incremental backups that are kept.
Backup Every Specifies how often the session is saved.
Record Section
Latch Record Enable Buttons When selected, multiple audio tracks can be record-enabled. When not selected, multiple audio tracks can­not be record-enabled. Record-enabling an au­dio track takes other audio tracks out of record­enabled mode.
Link Record and Play Faders When selected, Pro Tools does not remember separate fader lev­els for tracks when they are record-enabled, al­lowing you to maintain the same monitoring level for tracks during recording and playback.
Pro Tools Reference Guide64
Audio Track RecordLock This option configures Pro Tools tracks to either emulate a digital dub­ber, or to maintain legacy behavior for track record status.
• When selected, the record-enabled audio tracks remain record-enabled when play­back or recording stops.
• When not selected, record-enabled audio tracks are taken out of record enable when Pro Tools is stopped. This prevents tracks from remaining armed from pass to pass, emulating track record behavior of a digital dubber.
Transport RecordLock This option lets the Trans­port Record (the Record Enable button in the Transport controls) be configured to either em­ulate a digital dubber, or to maintain legacy be­havior for the Transport master Record.
• When selected, the Transport Record re­mains armed when playback or recording stops. This saves having to re-arm the Transport between takes, emulating digital dubber behavior.
• When not selected, the Transport Record disarms when Pro Tools is manually stopped or stops due to a loss of time code. This replicates standard Pro Tools record­ing behavior.
The Transport RecordLock preference is au­tomatically disabled and greyed out when Destructive record mode is enabled.
Disable “Input” When Disarming Track (In “Stop”) For flexibility, TrackInput monitor-
ing can be customized to remain selected re­gardless of track record status, or to automati­cally switch to Auto Input monitoring after a recording pass. This lets you optimize monitor­ing for a typical dubbing workflow (in which you might want tracks to remain in Input Only mode until explicitly switched to Auto Input monitoring) or a typical music tracking work­flow (in which leaving a track in Input Only monitoring mode after recording can result in accidental double-monitoring).
• When selected, taking an audio track out of record enable (any mode) takes it out of In­put Only mode, regardless of the global monitor mode, and switches it to monitor audio from disk only.
• When not selected, audio tracks remain in Input Only monitoring mode until explic­itly switched to Auto Input monitoring.
Mute Record-Armed Tracks While Stopped This setting determines monitor status of record­armed tracks.
• When selected, Pro Tools mutes all record­enabled tracks when the transport is stopped. Input can still be monitored while stopped using the TrackInput Monitor but­ton.
• When not selected, Pro Tools does not mute audio input on record-enabled tracks when the transport is stopped.
Chapter 6: Sessions 65
PEC/Direct Style Input Monitoring (Pro Tools HD Only) This option changes the way the Track-
Input monitoring mode is indicated on-screen (and on supported control surfaces) to emulate “PEC” (playback) and “Direct” (input/bus) indi­cation on some large format consoles.
• When not selected, the TrackInput button shows the letter “I.” The button remains gray to indicate Auto Input mode and lights green to indicate Input Only mode.
• When selected, the TrackInput button re­mains gray and shows the letter “D” to in­dicated Input Only mode (“Direct”); it lights green and shows the letter “P” to in­dicate Auto Input mode (“Pec” or play­back).
Online Options
Record Online at Time Code (or ADAT) Lock When selected, online recording begins as
soon as Pro Tools receives and locks to incom­ing time code.
Record Online at Insertion/Selection When se­lected, online recording begins at the edit cursor location. Recording continues until Pro Tools stops receiving time code. If you make a selec­tion, Pro Tools records online for the length of the selection.
Limit To Sets the maximum allowable recording duration. This can help reduce the time it takes to begin recording by allocating only a portion of your hard drive. The number of minutes spec­ified is allocated for each record-enabled track. You may want to experiment with this number to achieve the recording performance you want.
DestructivePunch File Length
This preference sets the duration of consoli­dated audio files when preparing tracks for De­structivePunch mode. The default value for this setting is 25 minutes.
Misc (Miscellaneous) Section
Auto Region Fade In/Out Length Sets a default length for fade-ins and fade-outs automatically applied to region boundaries. Using automatic fade-ins and fade-outs saves you the trouble of editing to zero-crossings or creating numerous rendered fades in order to eliminate clicks or pops in playback. Autofades are not written to disk. Value range is from 0–10 ms for the Auto Region Fade In/Out Length. A value of zero means that no auto-fading will occur. The Auto Fade value is saved with the session, and is auto­matically applied to all free-standing region boundaries until you change it.
Open Ended Record Allocation
This preference determines how much of your available hard drive space is allocated for record­ing.
Use All Available Space When selected, the drive’s entire available space is allocated. This can sometimes slow down the recording process for hard drives that use certain file systems, in­cluding HFS+ and NTFS.
Pro Tools Reference Guide66
Calibration Reference Level (Pro Tools HD Only)
Sets a default calibration reference level in dB when Pro Tools is in Calibration mode. For au­dio interfaces that have trims (such as the 192 I/O), see the interface’s guide for calibration instructions.
Delay Compensation Time Mode This option lets you choose whether information in the Delay Manager is displayed in milliseconds or sam­ples. This option is only available when Delay Compensation is enabled (Options > Delay Compensation).

Editing Preferences

Regions Section
Includes Take Region Names That Match Track Names When selected, only regions that share
the same root name with the track and playlist appear in the Takes List pop-up menu.
Includes Take Region Lengths That Match When selected, only regions that match the length of the current selection appear in the Takes List pop-up menu.
“Separate Region” Operates On All Related Takes When selected, editing a region with the
Separate Region command also affects all other related takes (recording passes) with the same User Time Stamp. This option helps you com­pare different sections from a group of related takes.
Region List Selection Follows Edit Selection When selected, selecting a region in a
track also selects it in the Region List.
Edit Selection Follows Region List Selection When selected, selecting a region in
the Region List causes Pro Tools to highlight that region’s occurrence in a track.
Auto-Name Separated Regions When selected, Pro Tools automatically names newly separated regions by appending a number to the region’s name. Disabling this option can be useful when importing region groups, REX files, or ACID files, because these file types can contain so many separate regions that it becomes difficult to read the Region List.
“Matching Start Time” Takes List
When you Control-click (Windows) or Com­mand-click (Mac) a region in a track, Pro Tools displays a list of regions whose time stamp matches the current Cursor location. The fol­lowing preferences determine which regions, or takes, appear in this list:
Memory Locations Section
Auto-Name Memory Locations When Playing When selected, Pro Tools gives new
Memory Locations default names based on their time location in the session. The time units cur­rently chosen in the View menu determine the units for the names.
Recall Memory Location at Original Track When selected, Memory Locations that recall a selec­tion also recall the track in which the selection was made.
Fades Section
Crossfade Preview Pre-Roll This option specifies the amount of pre-roll to be added when you are auditioning crossfades in the Fades dialog.
Crossfade Preview Post-Roll This option speci­fies the amount of post-roll to be added when you are auditioning crossfades in the Fades dia­log.
Chapter 6: Sessions 67
QuickPunch/TrackPunch Crossfade Length Spec­ifies a default length for crossfades created by QuickPunch or TrackPunch recordings. Cross­fades occur before the punch in and after the punch out.
Preserve Fades when Editing This option pre­serves fade-ins and fade outs, and converts sep­arated crossfades into corresponding fade-ins and fade-outs.
Default Fade Settings
Fade In Selects the default envelope shape for
fade-ins.

Mixing Preferences

Crossfade Selects the default envelope shape for crossfades.
Fade Out Selects the default envelope shape for fade-outs.
REX/ACID Selects the default envelope shape for fades and crossfades between regions (“slices”) in imported REX and ACID files.
Automatically Create Fades for Imported REX and ACID files
When selected, this option automatically ap­plies fades between regions (“slices”) within im­ported REX and ACID files to minimize clicks or pops during playback. If there is overlap be­tween slices, a crossfade is applied. If there is a gap between slices, a fade out is applied to the end of the first region. (The fade shapes applied to REX/ACID files follow the Default Fade Set­tings for REX/ACID.)
Levels of Undo
This preference sets the maximum number of actions that can be undone with the multiple undo feature. Setting this to a lower number can speed up the performance of slower computers. Pro Tools supports up to 32 Levels of Undo.
Setup Section
Sends Default to –INF When selected, the initial fader level of newly-created sends is set to – (no audible signal level). When not selected, the initial fader level of newly-created sends is set to 0 dB.
Send Pans Default to Follow Main Pan When se­lected, newly created sends have Follow Main Pan turned on, so the Send Pan controls follow the pan controls of the track. When not se­lected, newly created sends have Follow Main Pan turned off.
Link Mix and Edit Group Enables When selected, this option links enabling and disabling of Mix and Edit Groups. For example, enabling Group A in the Mix Window automatically enables Group A in the Edit window.
Use Absolute Pan Linking This option affects be­havior of grouped pan controls.
• When selected, grouped pan controls do not maintain relative offsets when any of the grouped pan controls is adjusted. All grouped pan controls snap to the absolute value of the adjusted control.
Pro Tools Reference Guide68
• When not selected, grouped pan controls maintain relative offsets when any of the linked controls is adjusted.
Default EQ
“Scroll to Track” Banks Controllers When using
a control surface (such as D-Control or Pro­Control) you can select this option to bank con­trol surface faders to a numbered track when us­ing the Track > Scroll to Track command.
This preference lets you choose any installed EQ plug-in as the default, which makes it available for quick assignment, both on-screen and on ICON work surfaces. On-screen, the plug-in ap­pears at the top of the Insert selector pop-up menu. On ICON work surfaces, the plug-in ap­pears first in the list of menu choices on the ro­tary encoders.
Default Dynamics
This preference lets you choose any installed Dynamics plug-in as the default, which makes it available for quick assignment, both on-screen and on ICON work surfaces. On-screen, the plug-in appears at the top of the Insert selector pop-up menu. On ICON work surfaces, the plug-in appears first in the list of menu choices on the rotary encoders.
Controllers
Edit Window Follows Bank Selection If you are using a supported control surface with Pro Tools, this option scrolls the Edit window to display the selected bank of tracks when you switch banks on the control surface, ensuring that the current bank is viewable on-screen.
Mix Window Follows Bank Selection If you are using a supported control surface with Pro Tools, this option scrolls the Mix window to display the selected bank of tracks when you switch banks on the control surface, ensuring that the current bank is viewable on-screen.
Always Fill Channel Strips When Banking If you are using an ICON worksurface, you can select this option to maximize the number of chan­nels displayed when banking. This setting opti­mizes the Bank commands to prevent the dis­play of a small number of channels at the extremes of the surface.
Touch Timeout If you are writing automation in Touch mode and you stop moving a non-touch sensitive fader or encoder, Pro Tools continues to write automation for the Touch Timeout value.
After the Touch Timeout period, writing of au­tomation stops and the automation data returns to its previous automation value at the rate spec­ified in the AutoMatch Time setting.
Automation Section
Smooth and Thin Data After Pass When se­lected, Pro Tools automatically smooths and then applies the specified amount of thinning to the automation data created in an automa­tion pass.
Degree of Thinning Specifies the amount of thin­ning performed on automation data when you using the Thin Automation command, or if you have selected the Smooth and Thin Data After Pass option.
Plug-in Controls Default to Auto-Enabled When selected, all applicable controls of newly added plug-ins are enabled for automation. When not selected, the controls of newly added plug-ins must be manually enabled for automation.
Chapter 6: Sessions 69
Suppress Automation “Write To” Warnings When selected, Pro Tools suppresses the warnings that appear after invoking any of the Write Auto­mation To Start, Selection, End, or Punch com­mands and then stopping the transport.
Latching Behavior for Switch Controls in “Touch” This option determines the behavior of
switch-type controls (such as mute or plug-in bypass) when writing automation in Touch mode.
• When selected, controls in Touch mode will latch in their current state. If an exist­ing breakpoint is encountered, writing of automation stops. If the transport is stopped while writing, the control will AutoMatch to the underlying value.
• When not selected, controls in Touch mode will not latch.
Allow Latch Prime in Stop When selected and any tracks are in Latch mode, any automation­enabled controls on those tracks can be set to new values while the transport is stopped by touching or moving controls, to prepare for the next automation pass.
Coalesce When Removing Slaves from VCA Group (Pro Tools HD Only) This option determines the
behavior when removing slave tracks from a VCA-controlled group.
• When selected, any automation on the VCA Master is automatically coalesced (without confirmation) to its slave tracks when the tracks are removed from the group.
• When not selected, a confirmation dialog lets you choose whether or not to coalesce the VCA Master automation to the slave tracks.
Standard VCA Logic for Group Attributes (Pro Tools HD Only) This option determines
which Mix group attributes may be selected in the Group dialog when the group is assigned to a VCA Master.
• When selected, Main Volume, Mute, Solo, Record Enable, and Input Monitoring con­trols on slave tracks follow the VCA Master only and are not available to be indepen­dently linked. (This emulates the behavior of analog console VCA masters.)
• When deselected, Main Volume, Mute, Solo, Record Enable, and Input Monitoring controls follow the VCA Master, but also re­main available for independent linking with groups.
Include Sends in Trim Mode This option deter­mines the Trim status of Send faders when a track is put in Trim mode.
• When selected, Send faders go into Trim mode along with the Main Volume fader.
• When deselected, the Main Volume fader goes into Trim mode, but the Send fader stays in the corresponding standard Auto­mation mode.
Include Control Changes in Undo Queue This op­tion determines whether certain mixer control changes, such as moving a fader or pan control, are entered into the Undo queue.
• When selected, mixer control changes ap­pear in the Undo queue, and are undone if any prior operation is undone.
• When deselected, mixer control changes will not appear in the undo queue, allow­ing you to undo other types of operations without losing the current mixer settings.
Any set to default operations that affect mixer controls will be entered into the Undo queue.
Pro Tools Reference Guide70
AutoMatch Time If you are writing automation in Touch mode, when you release a fader or con­trol, writing of automation stops and the auto­mation data returns to its previous value. The rate of return to the previous value is the Auto­Match Time.
AutoGlide Time (Pro Tools HD Only) Specifies how quickly Pro Tools transitions (glides) from one automation value to another, when Auto­Glide mode is used.
Amount of Memory to Reserve for Automation Re­cording Allocates memory for automation.
After Write Pass, Switch To (Pro Tools HD Only) Selects the Automation mode that
Pro Tools tracks automatically switch to after an automation pass in Write (or Write Trim) mode. You can choose to switch to Touch or Latch mode, or stay in Write mode by selecting No Change. After an automation pass in Write Trim mode, tracks automatically switch to the Trim version of the specified setting.

AudioSuite Buffer Size sets the size of the mem­ory buffer used for audio processing and pre­viewing with AudioSuite plug-ins. If AudioSuite preview stutters, set the buffer to Mini or Small.
Coalesce Trim Automation Options
(Pro Tools HD Only)
These options determine when Trim automa­tion is committed to the main automation play­list on a track.
After Every Pass Sets Trim automation to coa­lesce when the transport is stopped at the end of each Trim automation pass. No Composite Play­list is indicated.
On Exiting Trim Mode Sets Trim Automation to coalesce on a track when the track is taken out of Trim mode. A Composite Playlist can be viewed before committing Trim moves.
Manually Trim Automation can be coalesced only with the Coalesce Trim Automation com­mand. A Composite Playlist can be viewed be­fore committing Trim moves.
Use AudioSuite Dither When selected, applies a selectable dither plug-in to specific AudioSuite processing tasks (such as Gain and Normalize).
Plug-in Specifies the plug-in used for dither pro­cessing when the Use AudioSuite Dither option is selected.
Bit Depth Lets you select a bit depth for the dith­ered audio (24-bit, 20-bit, 18-bit, or 16-bit).
TC/E (Time Compression/Expansion) Section
TC/E Plug-in Lets you choose the plug-in used
for Time Compression and Expansion when you edit audio with the Time Compression/Expan­sion Trim tool. This Trim tool works by using Time Compression/Expansion to match an au­dio region to the length of another region, a tempo grid, a video scene, or other reference point.
Chapter 6: Sessions 71
Default Settings Specifies the default settings used by the chosen Time Compression/Expan­sion plug-in.
Import Section
Convert Imported “WAV” Files To AES31/Broad­castWave When selected, this option applies to
all newly imported WAV files, making them compliant with the AES31/EBU Broadcast stan­dard.
Automatically Copy Files on Import When se­lected, all audio files that are imported by drag­ging and dropping are copied to the current ses­sion’s Audio Files folder, regardless of whether the files need to be converted to the current ses­sion’s file type, bit depth or sample rate. Addi­tionally, when selected, the Import Session Data dialog defaults to “Copy from Source Media.” The Automatically Copy Files on Import prefer­ence does not affect the Import Audio com­mand.
Sample Rate Conversion Quality Lets you select the default sample rate conversion quality. Sam­ple rate conversion is used in a variety of Pro Tools processes including converting and importing audio files of different formats into a session, and bouncing and saving tracks to a dif­ferent sample rate or bit depth. The higher the quality of sample rate conversion you choose, the longer Pro Tools will take to process the au­dio file.

MIDI Preferences

Basics Section
Play MIDI Notes When Editing When selected, causes MIDI notes to sound when you insert them with the Pencil tool or drag them with any of the Grabber tools.
Use MIDI to Tap Tempo When selected, you can tap a MIDI keyboard to enter a new tempo value into a tempo field.
Display Events as Modified by Real-Time Proper­ties When selected, Pro Tools displays the ef-
fects of Real-Time Properties in both the Edit window and the MIDI Event List.

Pro Tools Reference Guide72
strument tracks are selected, the instrument in the selected track that is closest to the top of the Edit window (or closest to the left edge of the Mix window) will be used.
Pencil Tool Resolution When Drawing Controller Data Sets the default resolution for MIDI con-
troller data created with the Pencil tool. Setting this to a lower resolution helps avoid creating controller data that is unnecessarily dense. The value range is from 1 to 100 milliseconds.
Global MIDI Playback Offset Sets an offset in samples to compensate for MIDI latency. Enter­ing a value here has the same effect as setting an offset with the MIDI Track Offsets command. Offset values can be positive (later) or negative (earlier).

Synchronization Preferences

These preferences determine how a connected transport responds to Pro Tools.
Note Display Options
These options set the reference for middle C as C3, C4, or MIDI note number 60.
Delay for External Devices Options
(Pro Tools HD Only)
These options let you apply Delay Compensa­tion to Pro Tools-generated MIDI Time Code or MIDI Beat Clock. Generally, this delay should be applied when the external MIDI instrument is mixed externally, and should not be applied when the external MIDI instrument is mixed through the Pro Tools mixer.
These options are only available when a Delay Compensation Engine is chosen in the Playback Engine dialog and Delay Compensation is en­abled in Pro Tools.
This option is distinct from the hardware offsets available for hardware inserts (in I/O Setup).
Machine Control Section
Machine Chases Memory Location When se­lected, navigating to a specific location in a ses­sion with a Memory Location causes a con­nected transport to chase to that location.
Machine Follows Edit Insertion/Scrub When se­lected, navigating to a specific location in a ses­sion by moving the selection point or by scrub­bing a track will cause a connected transport to chase to that location.
Machine Cues Intelligently When selected, if you navigate to a cue point that is more than 10 sec­onds from the current location, Pro Tools will command a connected transport to fast wind to the new location at full speed to within 10 sec­onds of the cue point. Cueing will then slow to normal speed until the point is reached. This can significantly speed up tape cueing with cer­tain video transports.
Chapter 6: Sessions 73
Stop at Shuttle Speed Zero Causes Pro Tools to send a Stop command whenever you stop shut­tling. This is useful if you have a machine that requires an explicit stop command to park cor­rectly.
Non-Linear Transport Error Suppression
Punch In Frame Offset Sets an offset (in frames)
to compensate for punch in timing advances or delays.
Punch Out Frame Offset Sets an offset (in frames) to compensate for punch out timing advances or delays.
When Transport = Pro Tools, keeps Pro Tools from sending a Stop command when taken off­line. This prevents Pro Tools from stopping any other 9-pin devices connected to the system.
Delay Before Locking to Time Code Sets the amount of time (in frames) for Pro Tools to wait before attempting to lock to machines that issue servo lock messages. This setting allows time for the servo mechanisms to achieve stable lock.
Remote Mode (9-Pin Deck Emulation) Section
(Pro Tools HD Only)
Ignore Track Arming Sets Pro Tools to ignore in-
coming track arming (record enable) com­mands. This is useful if you are using a master controller to arm tracks on other machines, but you do not want to arm tracks in Pro Tools.
Set Servo Lock Bit at Play (Tamura Support) En­able this option when using a Tamura synchro­nizer to control Pro Tools in Remote mode to minimize lock-up times during recording.
Delay After Play Command Sets the amount of time (in frames) for Pro Tools to wait after re­ceiving a Play command before starting the au­dio engine. This can prevent false starts when locking to synchronizers that are not fully sup­ported by Pro Tools.
Synchronization Section
(Pro Tools HD)
Stable LTC Source When selected, this option
suppresses the normal 1-second wait time before Pro Tools attempts to lock to incoming LTC. En­able this option when locking Pro Tools to a sta­ble time code source (such as a non-linear tape machine or LTC generator) and not a linear tape machine.
Allow Track Arm Commands in Local Mode
Sets Pro Tools to respond to incoming track arm­ing (record enable) commands even when the system is not in Remote Mode. This is useful if you are using a paddle device to control Pro Tools track arming or punching.
Pro Tools Reference Guide74

Chapter 7: I/O Setup

The I/O Setup dialog provides tools to label, for­mat, and map Pro Tools input, output, insert, or bus signal paths for each session.
A signal path is a logical grouping of multiple inputs, outputs or busses that has a single name and (channel) format. In Pro Tools, paths are similar to stems, known to the film and video in­dustries (see “Stems and Stem Mixes” on page 77). The I/O Setup dialog lets you define and name paths according to the needs of each project.
With Pro Tools HD, the I/O Setup dialog pro­vides a graphical representation of the signal routing for each connected audio interface, with controls to route physical ports to Pro Tools in­puts and outputs. These controls mirror the routing controls found in the Hardware Setup dialog—changes made to physical routing in one dialog are always reflected in the other.
Each Pro Tools system can have a different I/O Setup configuration, determined by:
• Whether it is a Pro Tools LE, Pro Tools M-Powered, or Pro Tools|HD system
• On Pro Tools|HD systems, the number and types of audio interfaces
• On Pro Tools|HD systems, the Mixer plug­in currently installed (Stereo or Surround)
Each Pro Tools session retains its path configu­rations as I/O Settings. The I/O Settings saved with the session are loaded automatically when the session is opened. Unavailable items (in­cluding hardware, paths, or required resources) remain in the session as inactive items (see “Ac­tive and Inactive Paths” on page 86).
When you create a new session, you can specify a default I/O Setup configuration, including presets for stereo or multichannel mixing for­mats. Multichannel mixing requires a Pro Tools|HD system.
The I/O Setup dialog also lets you save and im­port I/O Settings files.
Navigating in the I/O Setup Dialog
To resize the I/O Setup dialog:
Drag the lower-right corner of the window ac-
cording to standard convention for your operat­ing system (Windows or Mac).
To scroll up or down in the Disk Allocation dialog:
Press Page Up or Page Down.
To scroll left or right in the I/O Setup dialog:
Press Alt+Page Up/Down (Windows) or Op-
tion+Page Up/Down (Mac).

Paths in Sessions
Paths and I/O Setup
In sessions, audio is routed using the track In­put, Output, Insert, Plug-in, and Send selectors. These selectors let you assign tracks to hardware inputs and outputs, internal busses, and other Pro Tools signal paths.
Paths comprise the lists of available signal rout­ing choices in track Input, Output, Insert and Send selectors.
Input Path selector and paths
The signal routing choices available in a session are defined in the I/O Setup dialog.

Main Paths and Sub-Paths

Paths in the I/O Setup dialog include main paths and sub-paths.
Stereo main path

Output Path selector and paths
Pro Tools Reference Guide76
Main and sub-paths in the I/O Setup Channel Grid
Main Paths
Main paths are logical groupings of inputs, in­serts, busses, or outputs. For example, a master stereo output path could be named Main Out. Path names in a stereo path are often appended with “.L” and “.R” for left and right.
Sub-Paths

Stems and Stem Mixes

A sub-path represents a signal path within a main path. For example, a default stereo output path consists of two mono sub-paths, left and right. Mono tracks and sends can be routed to either mono sub-path of the stereo output path.
It is especially useful to define and name sub-paths for complex mixing setups, such as a 5.1 Surround mix.

Default I/O Settings

A default I/O Settings file is installed automati­cally by Pro Tools, so you have a set of default paths that will get you started, without the need to configure the I/O Setup dialog. You can then customize your I/O Setup configuration at any time, according to the needs of each project (see “The I/O Setup Dialog” on page 78).
Default Settings Files
The default Stereo settings file is available on all Pro Tools systems, and provides stereo main paths, each with its own mono sub-paths.
The use of stems and stem mixes originated in the post production industry as a method to or­ganize and manage elements of a mix by type or content.
For example, a film mix often requires a stem mix for Foley, a stem mix for sound effects, a stem mix for dialog, and another for music. In this scenario, the dialog stem would contain all the dialog elements mixed relative to each other. The dialog stem can then be mixed with the other stems during the final mix of the scene or reel. The final mix is simplified by the ability to control the level of each stem, rather than the multitude of individual tracks that comprise a typical film mix.
In Pro Tools, you can work with main and sub­paths as you would stem mixes. These can be as­signed as needed, including the ability to assign multiple outputs to individual tracks and sends. For more information, see “Multiple Output As­signments” on page 536.
Multichannel settings files are available on Pro Tools|HD systems. These settings provide specialized path definitions for surround mix­ing. See “Configuring Pro Tools for Multichan­nel Sessions” on page 700.
Default Path Names
Default names for input, output, and insert paths are based on the type of system (Pro Tools LE systems) or type and number of interfaces (Pro Tools|HD systems) you are using.
Chapter 7: I/O Setup 77

Input and Output Selectors Select the physical ports on your audio interface to route to Pro Tools inputs and outputs. Ports are select­able in channel pairs. Available ports for each displayed interface are based on Hardware Setup settings; for example, if the AES/EBU inputs and outputs of an interface are enabled in Hardware Setup, they are available for routing in I/O Setup. The functionality provided with the In­put and Output selector is the same as that pro­vided on the Main page of the Hardware Setup dialog.
Path Name Column Shows paths that are avail­able for selection, including the name of each defined path. Path names can be renamed.
Show Original Setup Appears in the I/O Setup di­alog in certain session transfer situations. For details on this feature, see “Show Original Setup and Show Current Setup” on page 88.
Options Provide selectors with pop-up menus to set paths or orders for Controller Meter Path, Audition Paths (Region List previewing), New Track Default Output, and Default Path Order. See “I/O Setup Options” on page 90.

Routing Hardware I/O to Pro Tools I/O

The I/O Setup dialog lets you define which physical ports on your I/O peripheral are routed to available inputs and outputs in Pro Tools. Use the Input and Output selectors in the I/O Setup dialog to serve as a patchbay to route any of the physical inputs or outputs to your Pro Tools mixer.
Expand/Collapse Shows or hides the sub-paths associated with a main path.

5 Repeat the above step for additional channel
pairs.
6 Click OK.
Routing a Pro Tools Output Pair to Multiple Destinations
Pro Tools channel pairs can be routed to multi­ple outputs on an audio interface through the I/O Setup dialog. For example, if you assign both Analog 1–2 and Analog 3–4 interface outputs to Pro Tools Output pair 1–2, when you send a sig­nal to Pro Tools Outputs 1–2, that signal will be routed simultaneously to both pairs of output ports on your audio interface.
This lets you send the same signal (such as a ste­reo pair, a stem mix, or a multichannel mix) to multiple destinations (such as multiple master­ing devices).
Pro Tools outputs pairs can also be routed to multiple audio interface outputs in the Hard­ware Setup dialog. For information, see “Rout­ing a Pro Tools Output Pair to Multiple Destina­tions” on page 48.
To route a Pro Tools output channel pair to multiple audio interface output ports:

Creating and Editing Paths

The I/O Setup dialog lets you create and custom­ize signal path definitions.
Paths can be:
• Renamed, for easier identification after changing or renaming audio interfaces
• Remapped, to or from different sources or destinations
• Deactivated (or reactivated) to manage un­available or unnecessary I/O resources
• Deleted
In addition, you can import and export your I/O Setup configurations as I/O Settings files, as well as set default path parameters.
The following table lists the available path at­tributes for each path type.

Resetting to Default Paths

The Default button in the I/O Setup dialog pro­vides two primary functions:
• Creates new default paths up to the capacity of your system’s available audio interfaces and resources. See “Creating a Default Main or Sub-Path” on page 81.
• Resets selected path names to matching or corresponding paths in the current I/O Setup configuration. For example, if you replace an audio interface on a Pro Tools|HD system, you can use the Default switch to update your I/O Setup definitions with the new hardware configuration.
Interface names can be customized. See “Changing Interface Names” on page 82.
Chapter 7: I/O Setup 83
To reset path names:
Click Default.
If there are matching paths available with the new system configuration, existing paths will be updated to include new audio interfaces (Pro Tools|HD systems).
Resetting Mix Busses
(Pro Tools HD Only)
Pro Tools supports up to 128 mix busses (Pro Tools HD 7.x and Pro Tools TDM 6.9), 64 mix busses (Pro Tools TDM 6.7.x and lower), or 32 busses (Pro Tools 7.x and 5.0.1 and lower). When you open a session created with a lower version of Pro Tools, only the number of busses supported on the lower system are initially available. You can reset the number of available busses to match your system’s capabilities.
To delete a main path or sub-path:
1 In the I/O Setup dialog, select the path you
want to delete.
2 Click Delete Path.
To delete all paths:
1 Alt-click (Windows) or Option-click (Mac) any
path name.
2 Click Delete Path.

Channel Mapping

Once a path has been created and formatted, it can be mapped to specific audio interface, or bus channels in the Grid.
To map channels:
1 Select a main or sub-path.
To make all of your busses available in sessions created with a lower version of Pro Tools:
1 Open the I/O Setup dialog.
2 Click the Bus tab in the upper left.
3 Click Default.
Setting busses to the default setting will re­name all busses to their default name.

Deleting Paths

Path definitions can be deleted from the current session to reflect changes to your hardware setup, or to clean up track selector menus by re­moving unwanted or unnecessary path defini­tions. After deleting a path, any tracks or send assignments to that path are reset to No Output.
Pro Tools Reference Guide84
2 In the row for the selected path, click in the
Grid column under an audio interface and channel. Other channels for the path type, if any, fill to the right.
Mapping channels
For example, when mapping a new stereo path, clicking in the path row under output channel 1 fills both channel 1 and 2 (left to 1, right to 2).
To remap channels in a path, see “Remap­ping Channels” on page 85.
Channel Mapping and Surround Mixer
(Pro Tools HD Only)
When mapping multichannel paths, the left channel (L) is mapped first to the clicked Grid box, and remaining channels fill immediately to the right according to the default path order. Be­cause some multichannel mixing formats use unique track layouts, Pro Tools lets you set the default format in the I/O Setup dialog (see “I/O Setup Options” on page 90).
Customized Output paths for a 5.1 mix
Remapping Channels
Channel Shuffling
Moving a signal from right to left results in a shuffle of other signals after the new destination channel. Moving a signal from left to right shuf­fles any and all signals after the new destination channel and leaves the previous channel empty.
Changing a path’s format erases any cur­rent channel mapping.
Sub-Paths Follow Main Paths
When a main path is remapped, its sub-paths (if any) will remap automatically to maintain con­sistent routing. For example, remapping a stereo path to different hardware outputs results in any of its sub-paths moving with it.

Initializing I/O Setup

To set the current I/O Setup configuration:
Click OK in the I/O Setup dialog.
All paths must be valid before the I/O Setup con­figuration can be applied.
You can move the individual assignments to dif­ferent channels, to reorder the path’s definition (for example, changing a multichannel map to L-R-C-LF-LS-RS).
To remap channels in a path:
Drag the channel to the new location in the
Grid. Other channel assignments will move (shuffle) to accommodate dragged channels.
Chapter 7: I/O Setup 85
Valid Paths and Requirements
While configuring the I/O Setup dialog, certain rules apply for path definition and channel mapping.
Though it is possible to set up invalid mappings in the Channel Grid, Pro Tools will not accept an I/O Setup configuration unless all paths meet the path definition and channel mapping re­quirements, as follows:
Minimum Path Definitions All paths must have a name, be of a specific format, and have a valid I/O mapping.
Overlapping Channels and Valid Paths Channel mapping follows certain rules regarding over­lapping paths.
• There can be no partial or complete over­laps between any two main Output paths, any two Insert paths, or any two main Bus paths.
• A newly-created Output or Bus path must either be completely independent of other maps (not mapped to any other available I/O interface/channels), or it must be a sub­path completely contained within a larger path (for example, an LCR sub-path within a larger 5.1 path).
• Output and Insert paths can overlap in I/O Setup, but only one or the other can be used at any given time in a session. (Inputs, however, can be routed to multiple tracks.)

Active and Inactive Paths

Pro Tools paths can be Active (on) or Inactive (off, or unavailable). You can manually switch paths between Active or Inactive on a track-by­track or session-wide basis. In addition, Pro Tools sets paths to Inactive automatically when I/O is unavailable.
Track Path Assignments Track input, output, and bus path assignments can be switched to In­active using the corresponding selector on the track. This leaves track playlists intact, while dis­connecting that particular track from the output or bus path. Use this to remove a track from a signal path.
Session-Wide Path Assignments Paths can be globally activated or deactivated in the I/O Setup dialog. Use this to turn off a signal path on any and all tracks currently assigned to it. Pro Tools also sets unavailable paths to inac­tive. Paths can be unavailable when hardware or other system resources are unavailable, such as when opening a session saved on a different sys­tem.
Track Path Assignments
(Mix and Edit Windows)
To toggle a track path assignment to be Active or Inactive:
In the Mix or Edit window, Control-Start-click
(Windows) or Command-Control-click (Mac) the track’s Input, Output, Insert, or Send selec­tor.
Inactive track path assignments are listed in ital­ics and are unhighlighted.
Toggling All or All Selected
The Alt (Windows) and Option (Mac) modifiers apply the path toggle to all tracks. The Alt+Shift (Windows) and Option+Shift (Mac) modifiers apply the path toggle to all selected tracks. How­ever, Pro Tools will only apply the change to identical path assignments, if any, in the cur­rent track or tracks. Toggling multiple tracks only affects tracks that have the same path as­signment as the one you are explicitly toggling.
Pro Tools Reference Guide86
Toggling Multiple Paths
3 Set the Active/Inactive control for the path.
If a track has only one main output assignment, you can Control-start-click (Windows) or Com­mand-Control-click (Mac) the track’s Output Path selector to toggle the main output to inac­tive. When there are multiple assignments, the track selector will be displayed for you to specify the input, output, insert, or bus path.
If a Send (A–J) has multiple output assignments and one of those is toggled, then all of the out­put assignments for that Send (A–J) will be tog­gled.
Session-Wide Path Assignments
(I/O Setup Dialog)
Paths can be globally configured for Active or Inactive status in the I/O Setup Dialog.
Display of Active and Inactive Status
Unhighlighted (Italics) Indicates the path is inac-
tive.
Highlighted (Non-Italics) Indicates the path is ac­tive.
Highlighted (Italics) Indicates the path is active, but there are not enough system resources avail­able.

Hardware Setup and Session Transfer

Pro Tools sessions store the type and order of au- dio interfaces connected and active when the session was last saved.
Unavailable I/O
When opening a session, Pro Tools checks to see if the hardware configuration has changed since the session was last saved. If the current hard­ware configuration differs from that saved in the session, paths associated with the unavailable I/O are made inactive.
Remapping
Remapping occurs when a session’s original I/O Setup does not match that of the current system and session paths are remapped to cur­rent hardware.
Chapter 7: I/O Setup 87
Systems of equivalent I/O capability are remapped directly. For example, a session tracked to a Pro Tools|HD system through two 192 I/O audio interfaces would include 32 input paths spread across the two 16-channel inter­faces. The session is taken to a second Pro Tools system that has a 96 I/O audio interface (a 16­channel I/O unit) and a 1622 I/O (with its 16 an­alog inputs) connected to its Legacy Port. When the session is first opened on the second system, Pro Tools will map the 32 input paths to the in­puts of the two interfaces.
When hardware is unavailable to a session being opened, assignments can either be replaced us­ing the remap option, or opened as Inactive. Any tracks left assigned to an unavailable path will not be audible. This can be beneficial, how­ever, when you want to reassign tracks into your system’s mix one at a time.
See “Active and Inactive Paths” on page 86 for more information.
Show Original Setup and Show Current Setup
When a session is opened that contains path definitions for unavailable I/O interfaces, the I/O Setup dialog lists those paths in italics.

I/O Settings Files

I/O Settings can be managed when transferring sessions, and when developing I/O Setup con­figurations over the course of multiple sessions and projects.

Defaults, Settings Files, and Last Used Settings for New Sessions

When creating new sessions, you can set the ses­sion’s I/O Setup configuration using the follow­ing options:
Default I/O Setups The Pro Tools Installer pro­vides factory presets for stereo and surround I/O Setups (surround mixing is only supported on Pro Tools|HD systems). See “Factory I/O Settings Files” on page 90 for more information.
Custom Presets You can store and recall custom presets using the export and import features of the I/O Setup dialog.
Last Used The most recent (or last used) I/O Setup configuration is saved as a Last Used settings file. See “Last Used I/O Settings” on page 89 for more information.
The Show Original Setup button displays the au­dio interfaces used in the original session. This temporary display lets you check the original I/O configuration for reference while configur­ing the session for your system.
Once a session has been opened with unavail­able I/O retained, you can then reassign tracks to available I/O paths.
To redefine the paths, see “Creating and Editing Paths” on page 81.

Default I/O Settings at First Launch
The first time you create a session, you can choose default Stereo Mix or Surround Mix set­tings, depending on your system and installa­tion choices. See “Factory I/O Settings Files” on page 90.
