Chapter 2: Pro Tools System Configurations
There are two types of Pro Tools systems: TDM (Time Division Multiplexing) and LE. These re­fer to both the Pro Tools software and its associ­ated hardware, as follows:
• TDM = Pro Tools TDM software for Pro Tools|HD-series, Pro Tools|24 MIX-series, or Pro Tools|24 hardware.
• LE = Pro Tools LE software for Digi 002, Digi 002 Rack, Digi 001, Mbox, or Toolbox hardware.

Pro Tools TDM Systems

Pro Tools TDM systems are available in the fol­lowing configurations. Each system requires at least one Digidesign audio interface (sold sepa­rately). TDM systems can be expanded by add­ing Digidesign 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.

TDM System Playback, Recording and Voice Limits

The following table lists the audio playback, recording, and voiceable track limits of each type of Pro Tools TDM 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-series systems can open sessions with up to 256 audio tracks (and Pro Tools|24 MIX-series or Pro Tools|24 systems can open sessions with up to 128 audio tracks), but any audio tracks beyond that system’s voiceable track limit will be automatically set to Voice Off.
Pro Tools|HD-series systems provide up to 128 Auxiliary tracks (Auxiliary Inputs); Pro Tools|24 MIX­series and Pro Tools|24 systems provide up to 64 Auxiliary Inputs. All TDM-equipped Pro Tools sys­tems also provide a total of 64 internal mix busses, and up to 5 inserts and 5 sends per track (depend­ing on the DSP capacity of your system).
In addition, Pro Tools TDM systems support up to 256 MIDI channels (Pro Tools 6.x) or up to 128 MIDI channels (Pro Tools 5.1 to 5.3.x).

Pro Tools LE System Capabilities

Table 5 lists the playback, recording, and input and output capabilities of each Pro Tools LE system. All Pro Tools LE systems support up to 32 or 24 audio tracks, as noted in Table 5. (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 TDM 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 (Pro Tools
6.x), or will not open (Pro Tools 5.3.3 or lower). Additionally, with 5.3.3 or lower, if you save the ses­sion, the tracks beyond the voiceable track limit will be deleted from the session data.
All Pro Tools LE series systems provide up to 128 Auxiliary tracks (Auxiliary Inputs), a total of 16 in­ternal mix busses, and up to 5 inserts and 5 sends per track (depending on your computer’s processing capacity). In addition, Pro Tools LE systems support up to 256 MIDI channels (Pro Tools 6.x) or up to 128 MIDI channels (Pro Tools 5.1 to 5.3.x).

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

The Digidesign Audio Engine

DAE (or Digidesign Audio Engine) is Digide­sign’s real-time operating system for digital re­cording systems. When you install Pro Tools, DAE is automatically installed on your system.
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.
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.
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, mix automation, and MIDI functionality required by Pro Tools and other products from Digidesign and its Develop­ment Partners.
The DAE Playback Buffer Size determines the amount of memory allocated within DAE to manage disk buffers, which affects system per­formance. For more information, see “DAE Play­back Buffer Size” on page 42. The DAE Playback Buffer Size can be changed in the Playback En­gine dialog, discussed below.
Chapter 3: Pro Tools Concepts 11

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 TDM can also use host processing to run RTAS plug-ins for ef­fects processing. Performance is determined by your system and its Playback Engine settings.

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

The Playback Engine dialog lets you set a hard­ware buffer size and allocate a percentage of CPU resources for these tasks. For more informa­tion, see “Configuring Pro Tools System Set­tings” on page 39.
Playback Engine dialog for Pro Tools TDM system
The Playback Engine dialog is also where you se­lect the number of voices and voiceable tracks for your system and its sessions. Voice count choices in the dialog are based on how much DSP processing you want to allocate for voicing. For more information, see “Configuring Pro Tools System Settings” on page 39.
Pro Tools session file icon, Pro Tools 6.x
Pro Tools session file icon, Pro Tools 5.3 or lower
A session file is the document that Pro Tools cre- ates when you start a new project. The session file contains maps of all elements associated with a project, including audio files, MIDI data, and all your edit and mix information. You can make changes to a session and save those changes in a new session file. This lets you cre­ate multiple versions of a project or back up your editing and mixing work.
See also “System Resources” on page 16.
Pro Tools Reference Guide12

Audio File

When you record audio into a Pro Tools session, audio files are created.
Audio file icon, Pro Tools 6.x
Audio file icon, Pro Tools 5.3 or lower
Audio files for each session are stored in a folder named “Audio Files.” Audio files are listed in Pro Tools’ Audio Regions List and can appear in a track. A section of an audio file can be defined as a region. See “Regions (or Loops)” on page 13.

Tracks

Pro Tools tracks are where audio, MIDI, and au­tomation data are recorded and edited.
Audio and MIDI tracks 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.
Audio tracks can be mono, stereo, or any sup­ported multichannel format (depending on your type of Pro Tools system). When creating a new audio track, you can choose from a list of formats supported by your system.

Regions (or Loops)

Audio region
A region (or loop) is a piece of audio or MIDI data that may have associated automation data. A re­gion could be a loop, a guitar riff, a verse of a song, a sound effect, a piece of dialog, or an en­tire sound file. In Pro Tools, regions are created from audio or MIDI files, and can be arranged in audio and MIDI track playlists.
Audio tracks in the Edit window
MIDI track in the Edit window
Chapter 3: Pro Tools Concepts 13

Playlist

Playlist Selector pop-up menu
A playlist is a group 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 files to read 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 created to modify the length, fade-in, fade-out, and effects applied.
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 edit playlists for a track. This lets you assemble different versions of performances or edits on a single audio or MIDI track and choose between them with a pop-up menu on the track.
Each track 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 192 I/O audio interface (Figure 1) provides up to 16 channels of input and output to a Pro Tools|HD system. An 888|24 I/O audio interface provides eight channels of analog in­put and output to a Pro Tools TDM system.
Pro Tools Reference Guide14
The second use of the term channel refers to a mixer strip in the Pro Tools Mix window. The term channel strip refers to the mixer strip of any track (audio or MIDI track, Auxiliary Input, or Master Fader) in a session.
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.
Figure 2. Channel strip in the Mix window

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.)
Signal Routing Example
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.
Stereo
Inserts
Sends
Outputs to Stereo Bus path
plug-in
Input from Stereo Bus path
Output to Stereo Output path
The term channel also describes a separate aspect of MIDI operation. See “MIDI Con­cepts” on page 19.
Audio Tracks
Submixing to an Auxiliary Input
Chapter 3: Pro Tools Concepts 15
Auxiliary Input
Signal routing options include the following:
Track Input and Output (Track 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/or hardware inserts.
Sends Sends route audio to internal busses to send to other tracks in Pro Tools, or to hardware outputs.
Plug-In and Hardware Inserts Software plug-ins and hardware inserts process the audio on their associated track. 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 Pro Tools lets you define a group of multi­ple inputs, outputs, or busses that have a single name and (channel) format. These groups com­prise the lists of available routing choices in track I/O Selectors and other menus. Paths can be very useful for assigning stereo and multi­channel I/O routing or sub-paths within a path. See Chapter 7, “I/O Setup” for more informa­tion.

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 (such as H/W Buffer Size and CPU Usage) that affect its capacity for processing, playback, and record­ing. See “Configuring Pro Tools System Set­tings” on page 39.
Pro Tools allows for session items (such as
tracks and inserts) to be manually made inac­tive, to free up DSP resources. Inactive elements are viewable, editable, and retained within the session. See “Active and Inactive Items” on page 17.
All Pro Tools TDM systems, as well as LE sys-
tems (Pro Tools 6.x only), 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 “Voiceable Tracks and Track Priority” on page 96.
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-series and MIX-series only.)
Pro Tools Reference Guide16

Active and Inactive Items

Pro Tools lets you set certain items (such as tracks and inserts) as 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 tracks, Auxiliary Inputs, and Master
Faders
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 will automatically make items inactive if there are insufficient or un­available resources.
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 18).
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 18).
Tracks For TDM systems (Pro Tools 5.1 and higher) and LE systems (Pro Tools 6.x), when a track is made inactive, its voices become avail­able for another track. Mono inactive tracks free up one voice, and stereo and multichannel tracks free up one voice per channel. Addition­ally, when an audio track, Auxiliary Input, or Master Fader 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.
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:
Chapter 3: Pro Tools Concepts 17
Display of Inactive Items
Automatically 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 darkens.
Active Inactive plug-in
Inactive track
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, creating a session on a Pro Tools|24 MIX-series system, then opening it in on a Pro Tools|HD-series 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.
Active and inactive items and tracks
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.
Pro Tools Reference Guide18
To toggle an item active or inactive:
Control-Start-click (Windows) or Command-
Control-click (Macintosh) the item.
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 Macintosh). Side-chain in­puts support direct active and inactive switch­ing, but do not follow switching all or all se­lected.

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, 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; and, 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

MIDI Terms

The following are some basic MIDI terms:
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 Mackie HUI, that uses a MIDI connection to send control messages to a software program, but is not generally used to record MIDI infor­mation.
MIDI Sound Source Any MIDI instrument capa­ble of playing back MIDI-triggered sound. Sound sources receive MIDI from their MIDI IN ports.
MIDI signal flow
Not all devices will have all three MIDI ports (IN, OUT and THRU).
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-timbral). Each channel represents a discreet instrument sound; for in­stance, 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.
Multi-Timbral The capability of playing several different instrument sounds (such as piano, bass, and drums) simultaneously on separate channels. This makes it possible for a single MIDI sound source 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.
Chapter 3: Pro Tools Concepts 19
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.
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.
System Exclusive Data MIDI data commonly used for sending and retrieving patch parameter information for storage purposes.

Common Misconceptions about MIDI

MIDI is not audio. The messages that travel down a MIDI cable translate to specific instruc­tions. For instance, when you strike a key on your MIDI keyboard it sends a message to its MIDI OUT port telling another device (if con­nected and set to the same MIDI channel) to play that particular note.
Signal paths for MIDI instruments
However, to actually hear that second device (sound source) you’ll need to connect its audio outputs to a sound system. Your MIDI instru­ments have two signal paths, one for audio and another for MIDI.
MIDI does not allow you to use your devices be­yond their capabilities. Particular instruments have their own sound generation, polyphony, and multi-timbral limitations.
Pro Tools Reference Guide20

Chapter 4: Pro Tools Windows

Pro Tools provides two complementary ways of viewing a session: the Mix window and the Edit window. Pro Tools also allows you to control the transport and transport-related functions from the Transport window.
Depending on which version of Pro Tools you have, the Mix window and Edit window will ap­pear differently.
Pro Tools 6.x
For more information on the main elements of the Mix window and Edit window, see the page references provided in Figure 3 on page 22, and Figure 4 on page 23.
Pro Tools 5.3.x and 5.1.x
For more information on the main elements of the Mix window and Edit window, see the page references provided in Figure 5 on page 24, and Figure 6 on page 25.

The Mix Window

In the Mix window, tracks appear as mixer strips (or channel strips), with controls for inserts, sends, input and output assignments, volume, panning, record enable, automation mode, and solo/mute. The following section explains each of these track controls.
To display the Pro Tools input/output controls, inserts, sends, and comments, select Display > Mix Window Shows > All. You can choose to display all of these items, or some of them.
To toggle between the Mix and Edit win­dows: On Windows, press Control+Equals (=); On Macintosh, press Com­mand+Equals (=).

The Edit Window

The Edit window provides a timeline display of audio, as well as MIDI data and mixer automa­tion for recording, editing and arranging tracks. As in the Mix window, each track has controls for record enable, solo, mute and automation mode.
Systems with Pro Tools AVoption|XL installed also provide a timeline display of the movie track.
To display the input/output controls, inserts, sends, and comments in the Edit window, select Display > Edit Window Shows > All. You can choose to display all of these items, or some of them.

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 TDM 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 TDM systems, turn on your Pro Tools au-
dio interfaces. Wait at least fifteen seconds for your system hardware to initialize.
6 Turn on your computer.
Shut down your Pro Tools system in this order:
1 Quit Pro Tools and any other running applica-
tions.
2 Turn off or lower the volume of all output de-
vices in your system.
3 Turn off your computer.
4 For TDM systems, turn off audio interfaces.
5 For TDM 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
Pro Tools allows you to adjust the performance of your system by changing system settings that affect its capacity for processing, playback, and recording.
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.
7 Launch Pro Tools or any third-party audio or
MIDI applications.
Chapter 6: Sessions 39

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 Setups > Playback Engine.
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.

CPU Usage Limit

The CPU Usage Limit controls the percentage of CPU resources allocated to Pro Tools host pro­cessing tasks.
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.
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.
With Pro Tools 6.x, 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-processor computers. (The 99 percent setting dedicates one entire processor to Pro Tools.)
With Pro Tools 5.3.3 and lower, the maximum CPU Usage Limit is 85 percent.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
To change the CPU Usage Limit:
1 Choose Setups > 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.

Number of Voices

(TDM Systems Only)
On TDM 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.
Depending on the current sample rate and the number of TDM cards in your system, you will have different choices for voice count. For voice limits on different HD systems, see “TDM Sys­tem Playback, Recording and Voice Limits” on page 7.
Pro Tools Reference Guide40
To change the number of voices and DSP to allocate for voicing:
1 Choose Setups > Playback Engine.
Playback Engine dialog (Pro Tools 6.x)
Playback Engine dialog (Pro Tools 5.1.3)
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 (Pro Tools 5.3 and higher), or by clicking a value under Play­back Engine (Pro Tools 5.1.3).
• Select higher voice numbers when your Digidesign 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 Digidesign cards are in an expansion chas­sis, or when you are using other PCI cards along with Digidesign cards.
• Select minimum voice numbers if you are using high-bandwidth PCI cards (such as video capture cards) along with your Digidesign 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.
3 Click OK.

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.)
The Sample Rate setting can affect the number of available voices on TDM sys­tems.
To change the default Sample Rate (Pro Tools
5.3.x and higher):
1 Choose Setups > 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 46.)
In Pro Tools 5.1.x and lower, you can change the Sample Rate in the Session Setup window or the Hardware Setup window. Re­fer to the installation documentation in­cluded with your version of Pro Tools.
Chapter 6: Sessions 41

DAE Playback Buffer Size

The DAE Playback Buffer Size determines the amount of memory DAE uses to manage disk buffers, which affects system performance.
Lower DAE Playback Buffer Size settings can
improve playback and recording initiation speed. However, a lower setting can make it dif­ficult for slower hard drives to play or record tracks reliably.
Higher DAE Playback Buffer Size settings can
allow for a higher density of edits in a session. However, a higher setting can cause a time lag to occur before playback or recording begins. It can also cause a time lag to occur when you are ed­iting during playback.
To change the DAE Playback Buffer Size (Pro Tools 5.1.3):
1 Launch DAE. If Pro Tools is already running,
switch to the DAE application.
2 Choose File > Set Playback Buffer Size.
To change the DAE Playback Buffer Size (Pro Tools 5.3 and higher):
1 Choose Setups > Playback Engine.
Playback Engine dialog (Pro Tools 6.x)
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.
DAE Playback Buffer Size dialog (Pro Tools 5.1.3)
3 Select a buffer size.
4 Click OK.
5 Quit Pro Tools if it is running, or quit the DAE
application. The new buffer setting will take ef­fect when you launch Pro Tools again.

System Memory Allocation

(Pro Tools 6.x for TDM Systems 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.
To minimize system memor y allocation:
1 Choose Setups > Playback Engine.
Pro Tools Reference Guide42
2 Select the “Minimize System Memory Alloca-
tion” option.
3 Click OK.
4 On Windows systems, restart your computer.

On Mac OS X systems, enter your password when prompted, then restart your computer.
Configuring Pro Tools Hardware Settings
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 HD interfaces (with one or more MIX-series in­terfaces attached).
To configure a Pro Tools MIX-series, Pro Tools|24, or Pro Tools LE system, refer to the
Getting Started Guide that came with
that system.
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.
Hardware Setup dialog for 192 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.
Configuring Pro Tools|HD Hardware
On TDM systems, you configure Hardware set­tings for each audio interface connected to your system. For example, Pro Tools|HD-series sys­tems can have 192 I/O, 192 Digital I/O, or 96 I/O audio interfaces connected to HD Core and HD Process cards in the system. Those audio interfaces 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.”
Hardware Setup dialog for 192 I/O (Analog In page)

Chapter 6: Sessions 43
3 Click the Main tab.
4 From the Clock Source pop-up menu, select
the appropriate clock source for the system. In most 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 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.

connected to the HD-series audio interfaces in your system. Before you can configure a Legacy I/O, it must first be initialized in Hardware Setup (See “Initializing MIX-Series Peripherals (on an HD System)” on page 45.)
13 Click OK.
Pro Tools Reference Guide44
Initializing MIX-Series Peripherals (on an HD System)
9 Repeat the above steps for each additional
Legacy I/O.
Before you can configure a Legacy I/O, it must first be initialized in Hardware Setup.
To initialize a Legacy I/O on an HD system:
1 Start up your Pro Tools system. See “Starting
Up or Shutting Down Your System” on page 39.
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 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.
For more information on Hardware Setup controls for each Legacy audio interface, re­fer to the guide that came with the inter­face.
Configuring I/O Setup
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 sig- nal paths. For more information on paths, path labeling, and path mapping, see Chapter 7, “I/O Setup.”
The I/O Setup dialog also provides important audition, meter, and surround settings. For more information, see Chapter 7, “I/O Setup.”
7 From the Interface pop-up menu, select the
type of Legacy I/O you connected.
8 Set the External Clock Output on the HD in-
terface to 256x, which is the required clock speed for Legacy I/Os.
After you select an audio interface, the Main page updates with controls that can be config­ured. Refer to the guide for your audio interface for details on each control.
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).
Chapter 6: Sessions 45
To select multiple output por ts for a Pro Tools output channel pair:
1 Choose Setups > Hardware Setup.
2 From the Peripherals list, select an interface.
3 Click the Main tab.
4 Select an output port pair from an Output
pop-up menu.
5 Start-click (Windows) or Control-click (Macin-
tosh) the same pop-up menu a second time to choose an additional output port pair.
The output name updates with a plus sign (“+”) before it to indicate that multiple output ports are selected. In the pop-up menu, each physical port pair assigned to that Pro Tools output pair is indicated by a check mark.

Creating a New Session

The first step in beginning a Pro Tools project is creating a new session. When you do this, Pro Tools automatically creates a new folder named for your session. Within this folder is the session file and two subfolders (an Audio Files folder, and a Fade Files folder).
The Audio Files folder contains all audio re­corded or converted during the session. The Fade Files folder contains any crossfaded audio data generated by 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.
Typical session folder
Hardware Setup dialog for 192 I/O (Main page)
6 Repeat the above steps to select additional
output destinations. The only limit to output choices is the number of outputs available in your system.
Pro Tools output pairs can also be routed to multiple audio interface outputs in the I/O Setup dialog. For more information, see “Routing Hardware I/O to Pro Tools I/O” on page 69.

When choosing a bit depth or sample rate for your session, consider the disk space your selec­tion will require. 24-bit audio files occupy about 50 percent more disk space than 16-bit audio files. 192 kHz audio files occupy about four times the space as 44.1 kHz audio files.
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 with TDM sys­tems, see Appendix B, “TDM Mixing and DSP Usage.”)
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.
Chapter 6: Sessions 47

Opening a Session

When you open a session, Pro Tools looks in the session folder for audio and fade files linked to the session.
To open an existing session:
1 Choose File > Open Session.
2 Locate the session you want to open and click
Open.

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.
Opening a session with unavailable resources
Open Session dialog

Opening a Session that Contains Unavailable Files

(Pro Tools 6.x Only)
With Pro Tools 6.x, the DigiBase feature will prompt you if files are located but reside on Transfer volumes (such as CD-ROMs), or if any required files cannot be found. See “Locating Audio Files” on page 129, or the DigiBase Guide for more details.
Pro Tools Reference Guide48
The dialog contains a summary of the missing session components. To save a text file contain­ing a more detailed report, along with the result­ing action, click Yes.
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.
With Pro Tools TDM systems only:
Any tracks beyond the maximum number of
available voices on the current system are made inactive.
With Pro Tools LE 6.x only:
Any tracks beyond the maximum number of
available voices on the current system are set to voice off.
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.
With Pro Tools LE 5.3.x and lower only:
Any tracks beyond the maximum number of
available voices on the current system are re­moved from the session. If the session is saved, the removed tracks are lost.

Saving a Session

You should save regularly while working on your session to ensure that your work is pre­served on your hard drive.
Speeding up Saves by Reducing the Disk Cache Size
(Mac OS 9 Only)
To speed up session saves and Bounce to Disk re­cording, it is recommended that you reduce the Cache Size for your Macintosh to 512K (in the Control Panel > Memory dialog).

Saving the Session File

The Save Session command saves the changes you have made to your session and writes them over the previously saved version of the session file. The Save Session command cannot be un­done.
To save a session:
Choose File > Save Session.
To revert to the last saved version of a session:
Choose File > Revert to Saved.

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 Session As command. Because the Save Session 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.
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 Session 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 Session As.
2 Enter a new name for your session.
3 Click Save.
The renamed session file is saved in the session folder along with the original session. 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.
Chapter 6: Sessions 49

Saving a Copy of the Session

To save a copy of the current session along with its audio files and fade files, you can use the Save Session Copy In command. In addition, you can specify a session file format, audio file format, bit depth, and sample rate for the session copy.
Save Session Copy In dialog
Unlike the Save Session As command, Save Ses­sion 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 Session Copy In saves 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.
Dither and Noise Shaping with Save Session Copy In
Bit Rate 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
Session Format
You can save the session copy in the following formats, depending on your platform:
Windows:
• Pro Tools Session (*.pts); supports Pro Tools
5.1 and higher
• Pro Tools 5.0 Session (*.pt5)
• Pro Tools 4 24-Bit Session (*.p24)
• Pro Tools 4 16-Bit Session (*.pt4)
Macintosh:
• Latest; 5.1 or higher
• 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.
Using the Save Session Copy In command is the only way to change the sample rate of a session.
When you Save Session Copy In with a lower bit rate, Dither (and Noise Shaping) may be applied. See the following table:
Pro Tools Reference Guide50
Session Parameters
Audio File Type
The higher the quality of sample rate conver­sion you choose, the longer Pro Tools will take to process the audio file.
You can save the session to reference BWF (.WAV) or AIFF audio files. On the Macintosh, you can also save the session to reference SD II audio files (at sample rates up to 48 kHz).
SD II sessions are not supported with Pro Tools for Windows, or with sample rates higher than 48 kHz. You cannot set the session audio file type to SD II on the Macintosh if Enforce Mac/PC Compatibil­ity is selected, or if the sample rate of the destination session is greater 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.
Sample Rate
You can save the new session at sample rates of
44.1 kHz or 48 kHz (on Mbox, Digi 001 and MIX-series systems) and at sample rates up to 96 kHz (on Digi 002, Digi 002 Rack and HD-se­ries systems with a 96 I/O) or up to 192 kHz (on HD-series 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.
Enforce Mac/PC Compatibility
This setting forces Windows or Macintosh ver­sions of Pro Tools to create sessions and audio files that are usable on both platforms. For more information, see “Creating Macintosh and PC Compatible Sessions” on page 132.
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 Macintosh from SD II format to AIFF or BWF (.WAV) format with Enforce Mac/PC Compatibility selected.
Chapter 6: Sessions 51
Don’t Copy Fade Files
When this option is selected, Fade Files are not copied to the new session Fade Files folder. When the session is launched, the Find Files di­alog will prompt you to locate Fade Files. You can either locate the existing fades using the find file dialog, or Skip All to let Pro Tools recre­ate the fades from the session document.
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 point to the copied set­tings files.
Root Plug-In Settings Folder
3 Set the Audio File Type to AIFF, BWF (.WAV),
or SD II. If the audio files need to be compatible with either Windows or Macintosh, select AIFF or BWF (.WAV).
4 Set the Sample Rate and Bit Depth for the ses-
sion.
5 Select “Enforce Mac/PC Compatibility” if you
want to create session and audio files that can be used in either Windows or Macintosh versions of Pro Tools. See “Creating Macintosh and PC Compatible Sessions” on page 132 for more in­formation.
6 Select the Items to Copy to the new session.
7 Click Save.
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 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 (QuickTime video files or AVoption or AVoption XL video files) are copied to the new location, and session references are updated to point to the copied movie files.
To save a session copy in a new location:
1 Choose File > Save Session Copy In.
2 In the Save Session Copy dialog, choose a des-
tination and enter a name for the new session file.

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.
To create a custom session template in Windows:
1 Create a session and arrange its elements as
you want them to appear in the template. You can also define elements such as signal routings, insert and send configurations, track views, Ruler settings, and Preference settings.
2 Choose File > Save Session As.
3 Name the session and click Save.
Pro Tools Reference Guide52
4 Close the session.
5 Locate the session file that you just saved.
6 Right-click the file and choose Properties.
7 Under Attributes, deselect Archive and select
Read Only.
Making a session a Read Only file (Windows)

Creating Macintosh Templates

On the Macintosh, 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 Macintosh:
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.
2 Choose File > Save Session 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 > General Information.
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 and select the Archive option, make your modifications, then change it back to a Read Only file.
Saving a session as a Stationery Pad (Macintosh)
8 Select the Stationery Pad option to save the
file as a template, then close the information window.
Chapter 6: Sessions 53
To use this template, double-click it or open it with the Open Session command if you are al­ready running Pro Tools. You can create several custom templates for studio setups that you fre­quently use.
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.

Closing a Session

Because Pro Tools allows you to 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 Session or Save Session As command before closing the current 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 quit Pro Tools on the Macintosh:
Choose Pro Tools > Quit Pro Tools
(Pro Tools 6.x) or File > Quit (Pro Tools 5.3.x and lower).

Sharing Sessions Between Pro Tools TDM Systems and Pro Tools LE Systems

Opening a TDM session in Pro Tools LE

When opening a TDM session in Pro Tools LE, the following rules apply:
•With Pro Tools LE 6.x (all systems) or Pro Tools 5.3.1 and higher (Windows):
• Any tracks beyond the first 32, as well any inactive tracks, are set to voice off.
• Multichannel surround tracks are removed from the session.
• Any assignments to busses beyond 16 are made inactive.
• Unavailable input and output paths are made inactive.
• TDM plug-ins with RTAS equivalents are re­tained; those without equivalents are made inactive.
•With Pro Tools LE 5.3.x and lower (Macin­tosh) or Pro Tools LE 5.1.x and lower (Win­dows):
• Any tracks beyond the first 24, as well any inactive tracks, are removed from the ses­sion.
• Multichannel surround tracks are removed from the session.
• Any assignments to busses beyond 16 are made inactive.
• Unavailable input and output paths are made inactive.
• TDM plug-ins with RTAS equivalents are re­tained; those without equivalents are made inactive.

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
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.
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.
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.
Chapter 6: Sessions 55
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.
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.
Edit Window Default Length This option allows you to set a default length for the Edit window in hours, minutes, seconds, and frames. 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. There is a 13 hour maximum limit for the length of a Pro Tools session.
Edit Window Color Coding
Edit Window Color Coding determines how col­ors are assigned to the waveform display in the Edit window.
None Turns off color assignment to the wave­form display of tracks in the Edit window.
Tracks and MIDI Channels Assigns a color to the waveform display of each track in the Edit win­dow according to its voice number and MIDI channel assignment.
Tracks and MIDI Devices Assigns a color to the waveform display of each track in the Edit win­dow according to its voice number and MIDI de­vice type.
Groups Assigns a color to the waveform display of each track in the Edit window according to its group ID. If groups are suspended using the Sus­pend Groups command, all waveforms will be displayed in black.
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 this option is se­lected, track meters display the last peak level for three seconds.
Infinite Peak Hold When this option is selected, track meters display the last peak level until you click them to clear them.
No Peak Hold When this option is selected, track meters do not hold the peak level.
Zoom Toggle Track Height Sets the default track height when the Zoom Toggle function is used to zoom in on a selection.
Pro Tools Reference Guide56
Operation Preferences
Timeline Insertion Follows Playback This option causes the screen’s play cursor to update its loca­tion to the point where playback stops.
Edit Insertion Follows Scrub/Shuttle When se­lected, the edit cursor automatically locates to the point where scrubbing stops.
Support Background Record Applications (Pro Tools 6.0.x and Lower Only) Allows other
audio recording applications to run in the back­ground concurrently with Pro Tools. Files re­corded in the background can be imported into Pro Tools, and then trimmed and viewed while recording continues. (In Pro Tools 6.1, audio re­cording in the background is always supported.)
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.
Audio During Fast Forward/Rewind When se­lected, audio is audible during fast-forward or re­wind.
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. In Pro Tools 6.0 and lower, this option was located in the Compatibility page (see “Compat­ibility Preferences” on page 64).
Limit Pull Ups to NTSC/PAL Film Standards This option, which is selected by default, filters the list of available Pull Up rates that appears in the Session Setup window.
Latch Record Enable Buttons When this option is deselected, it prevents multiple audio tracks from being record-enabled. Record-enabling an audio track takes any other audio track out of record-enabled mode.
Latch Solo Buttons When this option is dese­lected, it prevents multiple tracks from being so­loed. Soloing a track will un-solo any other track that is soloed.
Link Mix and Edit Group Enables When this op­tion is selected, it links enabling and disabling of Mix and Edit groups. For example, enabling Group A in the Edit Window automatically en­ables Group A in the Mix window.
Use F11 Key for Wait for Note When this option is selected, pressing the F11 Function key puts MIDI recording in Wait for Note mode.
Automatically Copy Files on Import When this option is selected, Pro Tools copies all imported audio files to the current session’s Audio Files folder, regardless of whether they need to be converted to the current session’s file type, bit depth or sample rate.
Chapter 6: Sessions 57
Numeric Keypad Mode
Numeric Keypad Mode determines how the nu­meric keypad functions. You can always use the numeric keypad to select and enter values in the Event Edit Area, Location Indicators, and Trans­port fields.
Classic Emulates the way Pro Tools worked in versions lower than 5.0. With the Numeric Key­pad Mode set to Classic, you can play up to two tracks of audio in Shuttle Lock mode. Press the Start key (Windows) or Control (Macintosh), followed by 0–9 for different play speeds. Press Plus (+) or Minus (–) to reverse direction. Recall Memory Locations by typing the Memory Loca­tion number, followed by period (.).
Transport Allows you to set a number of record and play functions, and also operate the Trans­port from the numeric keypad. With the Nu­meric Keypad Mode set to Transport, you can play up to two tracks of audio in Shuttle Lock mode. Press the Start key (Windows) or Control (Macintosh), followed by 0–9 for different play speeds. Press Plus (+) or Minus (–) to reverse di­rection. Recall Memory Locations by typing pe­riod (.), the Memory Location number, and pe­riod (.) again.
Shuttle (TDM Only) (Selects a type of shuttling different from that of Shuttle Lock mode. With the Numeric Keypad Mode set to Shuttle, play­back is triggered by pressing and holding the keys on the numeric keypad—playback stops once the keys are released. Various 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.
AutoSave
This preference determines how the AutoSave feature functions.
Enable Session File Auto Backup When this op­tion is selected, Pro Tools automatically saves backups of your Pro Tools session file while you work. Use the Keep and Backup Every fields to specify the total number of incremental backups that are kept and how often the session is saved.
Online Options
Record Online at Time Code (or ADAT) Lock When this option is selected, online re-
cording begins as soon as Pro Tools receives and locks to time code or ADAT sync.
Record Online at Insertion/Selection When this option is 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.
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.
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.
Machine Control
These preferences determine how a connected transport responds to Pro Tools.
Pro Tools Reference Guide58
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.
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.
Ignore Track Arming Sets Pro Tools to ignore in­coming track arming (record enable) com­mands. This is useful if you are using a master controller to arm tracks on other machines, but you don’t want to arm tracks in Pro Tools.
Auto Regions 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 (the default) 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.
Calibration Reference Level Sets a default cali­bration reference level in dB when Pro Tools is in Calibration mode.
Remote Mode (9-pin Deck Emulation)
(TDM Systems Only)
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.
Delay After Play Command Sets an offset (in frames) to compensate for lockup time of exter­nal machines.
Chapter 6: Sessions 59
Editing Preferences
Recall Original Track Selections When this op­tion is selected, Memory Locations that recall a selection also recall the track in which the selec­tion was made.
Auto-Name Memory Locations When Playing When this option is selected, Pro Tools
gives new memory locations default names based on their time location in the session. The time units currently chosen in the Display menu determine the units for the names.
Auto-Name Separated Regions When this option is selected, Pro Tools automatically names newly separated regions by appending a number to the region’s name.
Region List Selection Follows Track Selection When this option is selected, selecting
a region in a track also selects it in the Regions List.
Track Selection Follows Regions List Selection When this option is selected, selecting
a region in the Regions List causes Pro Tools to highlight that region’s occurrence in a track.
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.
Default Fade Settings
Fade In Selects the default envelope shape for
fade-ins.
Crossfade Selects the default envelope shape for crossfades.
Fade Out Selects the default envelope shape for fade-outs.
Conversion Quality Selects the 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.
“Matching Start Time” Takes List
When you Control-click (Windows) or Com­mand-click (Macintosh) 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:
Take Region Names That Match Track Names When this option is selected, only re-
gions that share the same root name with the track and playlist appear in the Takes List pop­up menu.
Pro Tools Reference Guide60
Take Region Lengths That Match When this op­tion is 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 this option is selected, editing a re-
gion with the Separate Region command also af­fects all other related takes with the same User Time Stamp. This option helps you compare dif­ferent sections from a group of related takes.
QuickPunch Crossfade Length Specifies a default length for crossfades created by QuickPunch re­cording. Crossfades occur before the punch in and after the punch out.
Automation Preferences
Levels Of Undo 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 6.1 supports up to 32 Levels of Undo. Pro Tools 6.0 and lower support up to 16 Levels of Undo.
Faders Move During Playback When this option is selected, on-screen faders move if automation has been written for them. When this option is deselected, on-screen faders do not move, but automation still functions. Deselecting this op­tion can help speed up screen redraws and pro­cessing.
Smooth and Thin Data After Pass When this op­tion is selected, Pro Tools automatically smooths and then applies the specified amount of thinning to the automation data created in an automation pass. (See “Thinning Automa­tion” on page 447.)
Write Switches To Touch After Pass (TDM Sys­tems Only) When this option is selected, after an automation pass in Auto Write mode, Pro Tools automatically switches to Auto Touch mode. On TDM systems, you can choose to stay in Auto Write mode by deselecting this option.
Write Switches to Touch After Pass does not affect Trim mode. In Trim mode, tracks do not automatically change from Trim/Auto Write to Trim/Auto Touch after an auto­mation pass.
Chapter 6: Sessions 61
Mutes Follow Groups When this option is se­lected, muting a track that belongs to a Mix group mutes all members of the group. When this option is deselected, tracks are muted indi­vidually. You can also mute individual group members by Right-clicking (Windows) or Con­trol-clicking (Macintosh) their Mute buttons.
Solos Follow Groups When this option is se­lected, soloing a track that belongs to a Mix group solos all members of the group. When this option is deselected, tracks are soloed indi­vidually. You can also solo individual group members by Right-clicking (Windows) or Con­trol-clicking (Macintosh) their Solo buttons.
Send Mutes Follow Groups When this option is selected, muting a Send on a track that belongs to a Mix group mutes the corresponding Send (A–E) on all members of the group. When this option is deselected, Sends are muted individu­ally. You can also mute individual group mem­bers by Right-clicking (Windows) or Control­clicking (Macintosh) their Solo buttons.
Send Levels Follow Groups When this option is selected, adjusting the level of a Send on a track that belongs to a Mix group adjusts the level of the corresponding Send (A–E) on all members of the group.

Chapter 7: I/O Setup

The I/O Setup dialog provides tools to label, for­mat, and map Pro Tools input, output, insert, bus, and SampleCell signal paths for each ses­sion. (SampleCell paths are available only on Pro Tools|24 MIX-series systems on Mac OS 9 with TDM-equipped SampleCell II cards.)
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 67). The I/O Setup dialog lets you define and name paths according to the needs of each project.
On HD-series systems, 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 system or a Pro Tools TDM system
• On TDM systems, whether it is an HD-series, MIX-series, or Pro Tools|24 system
• On TDM systems, the number and types of audio interfaces
• On TDM systems, the mixer plug-in currently installed
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 76).
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 an HD-se­ries or MIX-series system).
The I/O Setup dialog also lets you save and im­port I/O Settings files.
Chapter 7: I/O Setup 65
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.
Track Input Selectors
The signal routing choices available in a session are defined in the I/O Setup dialog.

Main Paths and Sub-Paths

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

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
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 68).
The default Stereo settings file is available on all Pro Tools systems, and provides stereo main paths, each with its own mono sub-paths.
Multichannel settings files are available for Pro Tools HD-series and MIX-series systems. These settings provide specialized path defini­tions for surround mixing. See “Configuring Pro Tools for Multichannel Sessions” on page 490.
Default Path Names
Default names for input, output, and insert paths are based on the type of system (LE sys­tems) or type and number of interfaces (TDM systems) you are using.

Stems and Stem Mixes

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 398.

To configure I/O routing in I/O Setup:
1 Choose Setups > I/O Setup.
2 Click the Input or Output tab to display the
corresponding path type.
3 Click the Input or Output Selector for the first
interface channel pair, located below the first audio interface icon.
4 From the pop-up menu, select a physical port

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 more information, see “Routing a Pro Tools Output Pair to Multiple Destinations” on page 45.
To route a Pro Tools output channel pair to multiple audio interface output ports:
1 Choose Setups > I/O Setup.
2 Click the Output tab.
3 Click the Output Selector for an interface
channel pair, just below an audio interface icon.
4 From the pop-up menu, select a physical port
pair (such as Analog 1–2) to route to the corre­sponding Pro Tools channel pair (such as A 1–2) in the Path Name column on the left.
5 Start-click (Windows) or Control-click (Macin-
tosh) the same Output Selector and select an ad­ditional output pair from the same pop-up menu.
The output name updates with a plus sign (“+”) before it to indicate that multiple output ports are selected. In the pop-up menu, each physical port pair assigned to that Pro Tools output pair is indicated by a check mark.
6 Repeat the above steps to select additional
output destinations.
7 Click OK.
The only limit to output choices is the number of outputs available in your system.
0utput path assignments cannot overlap. See “Valid Paths and Requirements” on page 75 for details.

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.
Path Options by Type
Path Type Path Options (Attributes)
Input Names, formats, and source

Creating a Default Main or Sub-Path
You can set an I/O Setup path type to its default path configuration at any time.
To restore default paths and pathnames:
1 Choose Setups > I/O Setup.
2 Click the Input, Output, Insert, Bus, or
SampleCell tab to display the corresponding path type. (SampleCell paths are available only on Pro Tools|24 MIX-series systems on Mac OS 9 with TDM-equipped SampleCell II cards.)
3 Click Default.
Pro Tools creates all possible stereo main paths. Mono sub-paths are also auto-created for every stereo main path. These default path names ap­pear in a session’s track Input and Output Selec­tors.

are any overlapping or identically named paths, you will be instructed to correct them before the I/O Setup dialog will close. For more informa­tion, see “Initializing I/O Setup” on page 75.
Multichannel paths and mixing are ex­plained in Chapter 31, “Pro Tools Setup for Surround.”
Selecting and Arranging Paths
Individual and multiple paths can be selected in the I/O Setup dialog Path Name column. Se­lected paths and sub-paths can be moved higher or lower in the Path Name column to change their menu order in track Input, Output, Insert, and Bus Selectors. Paths can also be deleted. Sub-paths follow their main paths when they are moved in the I/O Setup dialog.
To select a main path or sub-path:
Click the path name.

tosh) any path name.
When all paths are selected, Alt-clicking (Win­dows) or Option-clicking (Macintosh) any path name, deselects all path names.
To rearrange paths:
Drag one or more path names up or down.
Resetting Mix Busses (TDM Only)
Pro Tools 5.1.3 and higher supports up to 64 mix busses for TDM systems. However, when you open a session created with Pro Tools 5.0.1 or lower, only 32 busses are initially available.
To make 64 busses available in sessions created with Pro Tools 5.0.1 or lower:
1 Open the I/O Setup dialog.
2 Click the Bus tab in the upper left.

Resetting 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 71.
• Resets selected path names to matching or corresponding paths in the current I/O Setup configuration. For example, if you change modes on Digi 001, or replace an audio inter­face on a Pro Tools HD-series or MIX-series 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 73.
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 (TDM systems), or I/O mode selection (Digi 001 only).
3 Click Default.
Changing Interface Names
Audio interface names can be customized in the I/O Setup dialog (Pro Tools TDM systems and Pro Tools 6.1 on LE). On TDM systems only, the I/O Setup dialog then bases default Input and Output path names on the custom names.
To rename an audio interface in the I/O Setup dialog:
1 Double-click the label above an interface.
2 Enter a new interface name.
3 Press Enter (Windows) or Return (Macintosh).

Chapter 7: I/O Setup 73

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.
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 (Macin-
tosh) 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, bus, or SampleCell channels in the Grid. (SampleCell paths are available only on Pro Tools|24 MIX-se­ries systems on Mac OS 9 with TDM-equipped SampleCell II cards.)
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 74.
Channel Mapping and Surround Mixer
(Pro Tools HD-Series and MIX-Series Systems 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 80).
To map channels:
1 Select a main or sub-path.
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
Pro Tools Reference Guide74
Customized Output paths for a 5.1 mix
Remapping Channels
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.
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.
Valid Paths and Requirements
While configuring the I/O Setup window, 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 and SampleCell paths, however, can be routed to multiple tracks.) (SampleCell paths are available only on Pro Tools|24 MIX-series systems on Mac OS 9 with TDM-equipped SampleCell II cards.)
Chapter 7: I/O Setup 75

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 window. 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.
Toggling All or All Selected
The Alt (Windows) and Option (Macintosh) modifiers apply the path toggle to all tracks. The Alt+Shift (Windows) and Option+Shift (Macin­tosh) 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.
Toggling Multiple Paths
If a track has only one main output assignment, you can Control-start-click (Windows) or Com­mand-Control-click (Macintosh) the track’s Output 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–E) has multiple output assignments and one of those is toggled, then all of the out­put assignments for that Send (A–E) will be tog­gled.
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 (Macin­tosh) the track’s Input, Output, Insert, or Send Selector.
Inactive track path assignments are listed in ital­ics and are unhighlighted.

Hardware Setup and Session Transfer

Sessions created in Pro Tools 5.1 or higher store the type and order of audio 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.
Systems of equivalent I/O capability are remapped directly. For example, a session tracked to a Pro Tools HD-series 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 inter-
Chapter 7: I/O Setup 77
face (a 16-channel 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 76 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.
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 71.

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-series and MIX-series systems). See “Factory I/O Settings Files” on page 80 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 79 for more information.
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 80.
Pro Tools Reference Guide78
Importing and Exporting I/O Settings Files
You can export and import I/O Setup configura­tions as I/O Settings files. This lets you save set­tings for different projects, import settings for reconfiguring I/O Setup, and manage path defi­nitions and signal routing setups.

To export and save an I/O Setup configuration:
1 Click Export Settings.
2 Name and save the settings file.
To start sessions with a blank or empty I/O Setup dialog, you can create and export an I/O Settings file in which all definitions have been deleted.
Importing I/O Settings
I/O Settings can be imported before you open a session, or you can import settings into a session that is already open (see “Default I/O Settings at First Launch” on page 78).
When you import I/O Settings in an existing ses­sion, you can choose to delete any unused path definitions before importing the new paths, or leave unused path definitions intact and add the new paths to the current I/O Setup configura­tion.
• Click Yes to remove any unused paths and add the imported paths to the current I/O Setup configuration. Any I/O assignments and automation data associated with the unused paths are also deleted.
• Click No to add the imported paths to the current I/O Setup configuration.
If the import results in overlapping paths, the new paths will appear in the I/O Setup dialog as Inactive. (See “Active and Inactive Paths” on page 76.)
After importing I/O Settings, you can then reas­sign path routing definitions in the I/O Setup di­alog by remapping, renaming, and deleting paths. (See “Creating and Editing Paths” on page 71.)
Last Used I/O Settings
If any changes are made to the I/O Setup dialog during a session, these changes are saved to the Last Used settings file when the I/O Setup dialog is closed (by clicking OK).
Changes to I/O Setup are saved along with the current session. User Presets files will not con­tain recent changes unless you export an up­dated settings file.
The Last Used settings are available as a choice when creating or opening sessions, in addition to the factory presets described below.
To import I/O Settings:
1 Click Import Settings in the I/O Setup dialog.
2 Select an I/O settings file in the Import Set-
tings dialog and click Import.
3 A dialog appears asking whether you want to
delete existing paths. Do one of the following:
Chapter 7: I/O Setup 79
Factory I/O Settings Files
Pro Tools provides I/O Settings files for Stereo and Surround mixing. These files provide ge­neric main and sub-path definitions for either mixing format.
Stereo Mix Settings File
The Stereo Mix preset consists of all possible ste­reo and mono paths for your session.
Using the “Stereo Mix” preset has the same effect as clicking Default for every individ­ual tab in I/O Settings. See “Creating and Editing Paths” on page 71 for details.
Specifically, the Stereo Mix preset will create the maximum number paths of each type, as deter­mined by the available system’s I/O Setup and hardware configuration.
To convert a session so that it emulates Direct Outs mode, use the Auto Assign Ascending Out­puts feature, as follows:
To auto assign track outputs for Direct Out:
1 Make sure that all tracks you want to assign
are visible (hidden tracks will not be affected).
2 Select the tracks you want to assign by Shift-
clicking their track names.
3 Control-Alt-click (Windows) or Command-
Option-click (Macintosh) the Output Selector of the leftmost track and assign it to the sub-path for Output #1. All visible tracks will be auto-as­signed to unique mono sub-path outputs in as­cending order.

I/O Setup Options

Surround Mix Settings File (TDM Systems Only)
The Surround Mix provides additional, sur­round-specific Output and Bus presets. See “Sur­round Mix Settings Files” on page 491 for more information.
About Direct Outputs Mode
Direct Outputs mode, as found in older versions of Pro Tools, has been replaced by the default mono sub-paths available through all valid I/O in the I/O Setup dialog.
The Default switch creates main Output paths with appropriate mono sub-paths. These sub­paths provide discrete monophonic routing.
When a session is opened that was saved in Di­rect Outputs mode, Pro Tools maps all the out­put assignments to equivalent mono sub-paths (as available). See “Hardware Setup and Session Transfer” on page 77 for more information on remapping.
Pro Tools Reference Guide80
Pro Tools systems have additional I/O Setup fea­tures. These include default signal routing for metering and auditioning, and default track lay­out for multichannel mix formats.

Meter Path Selector

(ProControl Only)
The Meter Path Selector determines the path displayed across the ProControl Output meters. See the latest ProControl documentation for more details.

Audition Path

The Audition path is the output path through which files and regions are previewed (listened to) in the Regions List.
Using the Default Audition Path
When you audition a file or region in the Re­gions List, Pro Tools routes the audio output through the Audition path. Pro Tools assigns a default Audition path to the first available main Output path of the corresponding format. You can also select a different Audition Path in the I/O Setup dialog.
On TDM systems with more than one audio interface, you can only select the first audio interface as an audition path.
To audition regions in the Regions List:
Alt-click (Windows) or Option-click (Macin-
tosh) the region in the list.
Auditioning Discrete Signals in Multichannel Items
In the Audio Regions List, multichannel regions are auditioned through the current Audition path. Signals can be auditioned “in-place,” or through all outputs, as described below.
Audition In-Place
Configuring Audition Paths
You can specify the monitoring outputs for Re­gions List auditioning using the Audition paths menu.
Audition Path Main Menu The main menu con­sists of all path format choices available on the current system (Mono and Stereo on all systems, LCR and greater on HD-series and MIX-series systems).
Audition Path Submenus Each path format choice has a submenu listing Output paths of that given format. (The mono submenu lists Output paths of any format.)
To configure Audition paths:
Select a path from the Audition path menu or
submenus.
When auditioning a mono component of a mul­tichannel region, that mono component will by default be auditioned in-place. That is, it will play from the corresponding speaker channel of its parent multichannel region.
To audition in-place:
1 In the Regions List, make sure the stereo or
multichannel region is in expanded view (show­ing .L, .R, and other component channels).
2 Alt-click (Windows) or Option-click (Macin-
tosh) the region for the channel you want to au­dition.
Audition to All Outputs
Mono regions can be routed equally to all out­puts of the parent region’s Audition path.
To audition through all channels of the main audition path:
Shift-Alt-click (Windows) or Shift-Option-
click (Macintosh) on the signal in the Regions List.
Selecting an Audition path
Chapter 7: I/O Setup 81

Default Path Order

(TDM Systems Only)
The Default Path Order Selector lets you select the default track layout you want Pro Tools to follow when creating and mapping 5.1-format main or sub-paths in the I/O Setup dialog.
This setting does not affect existing path defini­tions or metering—it only specifies channel mapping in new 5.1-format paths.
To choose a Default Path Order:
Select the channel mapping from the Default
Path Order menu.
Default Path Order Selector
For more information about multichannel mix­ing, see Chapter 31, “Pro Tools Setup for Sur­round.”

Default Output Path

You can specify the default Output path assign­ment for new tracks, in each available format.
To specify a default Output in the I/O Setup window:
Select a format and Output path from the De-
fault Output Selector.

Chapter 8: Tracks

This chapter covers basic track management tasks such as creating and deleting tracks, as­signing voices and output channels, and group­ing tracks.

Track Types

In a Pro Tools session, you can have several dif­ferent types of tracks. These can include audio tracks, Auxiliary Input tracks, MIDI tracks, Mas­ter Fader tracks, and QuickTime Movie tracks. AVoption|XL Movie tracks are supported on Pro Tools 5.3.3 and higher (Windows), Pro Tools 6.1 (Mac OS X), and 5.1.x (Mac OS 9)
QuickTime Movie track features are de­scribed in Chapter 36, “Working with QuickTime Movies.”
Audio Tracks, Auxiliary Input Tracks, and Master Fader Tracks
Pro Tools provides mono, stereo, and greater­than-stereo multichannel format audio tracks, Auxiliary Inputs, and Master Faders.
Audio Tracks
Audio tracks contain arrangements of recorded (or imported) audio files. Audio tracks can be mono, stereo, or multichannel format (multi­channel tracks are supported on Pro Tools HD­series and MIX-series systems only).
Auxiliary Input Tracks
Auxiliary Input tracks can be used as effects sends, destinations for submixes, as a bounce destination, as inputs to monitor or process au­dio (such as audio from MIDI sources), and for many other audio routing tasks.
Master Fader Tracks
Master Fader tracks control the overall level of the audio tracks that are routed to the session’s main output paths. For example, you could have 24 tracks in a session with channels 1–8 routed to Analog Output 1–2, channels 9–16 to Analog Output 3–4, and channels 17–24 to An­alog Output 5–6. You could then create three master faders, one to control each of these out­put pairs.
Master Fader tracks have additional uses (such as controlling submix levels). For more informa­tion, see “Master Faders” on page 392
Chapter 8: Tracks 83
MIDI Tracks
MIDI tracks store MIDI note, instrument, and controller data. You cannot select a track format when you create a MIDI track, because audio does not pass through it.
Track Formats
Mono Tracks
A mono audio track, Auxiliary Input, or Master Fader track controls volume, and, in some cases, panning, for a single channel of audio. A mono track uses a single voice.
Stereo Tracks
A stereo audio track, Auxiliary Input, or Master Fader track is a single channel strip that plays two channels of audio as a stereo pair. Stereo tracks use two voices.
Multichannel Tracks (Pro Tools HD-Series and MIX-Series Systems Only)
A multichannel track is a single channel strip that plays multiple channels of audio (from 3–8 channels at a time). This allows Pro Tools to support multichannel mixing formats including LCRS, 5.1, 6.1, and others.
For more information on surround mixing with Pro Tools, see the following chapters:
• Chapter 31, “Pro Tools Setup for Surround”
• Chapter 32, “Multichannel Tracks and Signal Routing”
• Chapter 33, “Surround Panning and Mixing”
Audio Track Channel Strips
Each audio track has its own set of controls for volume, pan, output window, record enable, au­tomation mode, solo, mute, and voice assign­ment. Audio tracks also have a Comments View to enter and display comments.
With slight variations, audio track channel strips in the Mix window look like the tracks shown in the following figures.
Audio tracks can be added to a session with the New Track command.

For details on Input and Output Selectors, see “Assigning Inputs and Outputs to Tracks” on page 92.

Volume/Peak/Channel Delay Indicator

The Volume indicator on an audio track has three display modes: Volume, Peak, and Chan­nel Delay.
To toggle the Volume indicator display:
Control-click (Windows) or Command-click
(Macintosh) the indicator to toggle it between the following modes:
Volume Indicator Shows the current volume, or input level of a track as set by the track Volume fader.
Peak Indicator Functions as a headroom indica­tor based on the last peak playback level. To re­set the peak counter, click anywhere in the
meter. Values range from –(no signal) to 0 dB.
Channel Delay Indicator Shows the total delay, in samples, incurred on the track from the use of any TDM plug-ins on that channel.
The Pan slider controls the balance of a track be­tween the assigned output pair. It only appears if you are using stereo tracks or mono tracks routed to a stereo output.
The Pan slider on a MIDI track is effective only if you are controlling a sound module that sup­ports MIDI panning.

Volume Fader

The Volume fader controls the volume of a track when it is in playback, and the monitor level of the track when it is in record. You can link the record and monitor levels by enabling the Oper­ation Preference for “Link Record and Play Fad­ers.”
The volume fader on a MIDI track is effective only if you are controlling a sound module that supports MIDI volume.

Track Level Meter

On audio tracks, level meters indicate the level of the signal being recorded or played back from the hard drive. Green indicates nominal levels; Yellow indicates pre-clipping (–6 dB below full scale); and Red indicates clipping. When a track is record-enabled, these meters indicate record levels.
On MIDI tracks, the level meter shows the MIDI velocity of the most recent MIDI event.
Chapter 8: Tracks 87
Pre- and Post-Fader Metering
You can globally set audio track level meters to indicate pre-or post-fader levels by selecting or de-selecting Operations > Pre-Fader Metering. When pre-fader metering is selected, the level meters show levels independent of fader posi­tion. With post-fader metering, the level meters respond to fader position.
Peak Hold
If clipping occurs, the topmost LED will stay lit (red). In addition, Pro Tools meters provide a peak hold feature with three options: 3 Second Peak Hold, Infinite Peak Hold, or No Peak Hold.
To enable Wide Meters View:
Command-Option-Control-click the track
level meters in either the Mix window or the Edit window.
To choose a peak hold setting:
Choose Setups > Preferences, click Display,
and select a Peak Hold option.
You can clear a meter’s clipping or peak hold in­dicator.
To clear a meter:
