Chapter 2: Pro Tools Concepts

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

Hard Disk Audio Recording

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.
This differs from tape-based recording, which is a linear medium—where you need to rewind or fast forward to hear a particular spot in a record­ing. To rearrange or repeat material in a linear system, you need to re-record it, or cut and splice it.
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 nonde- structive, meaning that the original recorded ma­terial is not altered.

Pro Tools Nonlinear Editing

Pro Tools is a nonlinear recording editing sys­tem that lets you rearrange and mix recorded material nondestructively. Nonlinear editing simply means that you can cut, copy, paste, move, delete, trim, and otherwise rearrange any audio, MIDI, or video in the Pro Tools Edit win­dow.
Nonlinear editing provides significant advan­tages over dubbing (re-recording), and cutting and splicing magnetic tape. It gives you the greatest possible flexibility for editing and ar­ranging, and it is all nondestructive and “undo­able.” Additionally, with nonlinear editing in Pro Tools, you will never introduce any degrada­tion of audio fidelity as you would with tape.
Chapter 2: Pro Tools Concepts 7

The Digidesign Audio Engine

The Digidesign Audio Engine (DAE) is a real­time operating system for digital audio record­ing, playback, and processing. When you install Pro Tools, DAE is automatically installed on your system.
In the same way that a computer’s operating sys­tem provides the foundation for programs that run on the computer, DAE provides the founda­tion for much of the hard disk recording, digital signal processing, and mix automation required by Pro Tools and other products from Avid and its Development Partners.
The DAE Playback Buffer Size determines the amount of memory DAE allocates to manage disk buffers. The DAE Playback Buffer Size can be changed in the Playback Engine.
For information on configuring the DAE Playback Buffer Size, see “DAE Playback Buffer Size” on page 56.
Pro Tools LE uses host (CPU) processing to pro­vide audio track recording, playback, mixing, and effects processing. Both Pro Tools LE and Pro Tools HD use host processing to run RTAS (Real-Time AudioSuite) plug-ins for effects pro­cessing. Performance is determined by your sys­tem and its Playback Engine settings.
The Playback Engine lets you set a hardware buffer size and allocate a percentage of CPU resources for these tasks.
®
Playback Engine
Pro Tools lets you adjust the performance of your system by changing system settings that affect its capacity for processing, playback, and recording. These system settings are available in the Playback Engine (Setup > Playback Engine).
Pro Tools takes advantage of your computer’s host processor for certain tasks and optional host-based DSP processing.
Pro Tools Reference Guide8
Playback Engine for Pro Tools|HD system
On Pro Tools|HD systems, you can select the number of voices and voiceable tracks for your system and its sessions. Voice count choices are based on how much DSP processing you want to allocate for voicing.
On Pro Tools|HD systems, the Playback Engine is also where you assign dedicated resources for Delay Compensation.
For more information, see “Configuring Pro Tools System Settings” on page 50. See also “System Resources” on page 20.

MIDI

passes input
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, MIDI patch bays, effects processors, MIDI interfaces, MIDI control sur­faces, and MIDI sequencers.
MIDI devices are equipped with 5-pin DIN con­nec tors, label ed as ei ther I N, OUT , or THR U. The MIDI OUT port transmits messages. The MIDI IN port receives messages. The MIDI THRU out­puts whatever is received from the IN port. MIDI devices are connected with MIDI cables that are available at most music stores.
USB and FireWire-compatible MIDI devices send and receive MIDI messages to and from the computer over USB or FireWire.
strument sound. For example, bass on channel 1, piano on channel 2, and drums on channel 10. Similar to a multitrack tape re­corder, a MIDI sequencer can record complex ar­rangements—even using only a single multitim­bral keyboard.

The following are some basic MIDI terms:

MIDI Interface Hardware that lets computers connect to and communicate with MIDI devices (such as the M-Audio MIDISPORT).
MIDI Device Any physical MIDI 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 MIDI keyboards, MIDI guitar controllers, MIDI wind controllers, and others. Controllers transmit MIDI from their MIDI OUT ports.
MIDI signal flow
Not all devices will have all three MIDI ports (IN, OUT, and THRU).
The MIDI protocol provides 16 channels of MIDI per port. A single MIDI cable can transmit a separate set of messages for each of the 16 channels. These 16 channels can correspond to separate MIDI devices or to multiple channels within a single device (if the device is multitim- bral). Each channel can control a different in-
MIDI Control Surface Any device (such as Com­mand|8), which uses a MIDI connection to send control messages to a software program, but is not generally used to record MIDI information.
Multitimbral The ability of one MIDI device to play several different instrument sounds (such as piano, bass, and drums) simultaneously on separate MIDI channels. This makes it possible for a single multitimbral MIDI instrument to play back entire arrangements.
Chapter 2: Pro Tools Concepts 9
MIDI Port A physical MIDI port on a MIDI inter­face or a virtual MIDI port created in software. There are separate ports for MIDI In and Out. Physical MIDI ports connect to external MIDI devices using MIDI cables. Virtual MIDI ports connect software plug-ins and applications (see also “Virtual MIDI Nodes”).
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 correct messages.
Program Change Event A MIDI command that tells a sound source which of its sounds (or sound patches) to use. The MIDI protocol lets you choose from a range of 128 patches.
Bank Select Message Many devices have more than 128 patches, which are arranged in banks. The Bank Select Message is a MIDI command that specifies the bank of patches from which to choose.
Local Control A controller setting found on most MIDI keyboards that lets them play their own sound source. Disabling “local control” ensures that a device’s internal sound source is only played by external MIDI messages (such as those sent from Pro Tools when MIDI in Pro Tools is routed to the MIDI keyboard). When using Pro Tools, “local control” should usually be dis­abled (for example, when using MIDI Thru). 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.
Virtual MIDI Nodes When using MIDI with in­strument plug-ins in Pro Tools, virtual MIDI nodes are created. These nodes act like MIDI ports and provide software MIDI connections between Pro Tools and other MIDI software, such as instrument plug-ins. For example, when you insert Propellerhead’s Reason as a ReWire client on a track, the various MIDI inputs to Reason become available to Pro Tools MIDI and Instrument track MIDI outputs.
Common MIDI Misconceptions
MIDI is not audio, and by itself makes no sound. MIDI is control information only. It is like the piano roll for a player piano; it provides control information for what note to play when, for how long, at what volume, and with what sound (instrument). For example, when you strike a key on a MIDI keyboard, it sends a mes­sage to a MIDI instrument to play that particular note at that particular velocity using the se­lected sound (instrument). This could be its in­ternal tone generator (like a synthesizer or sam­pler), another external MIDI instrument, or an instrument plug-in within Pro Tools. In order to play and hear a MIDI recording, you must have a MIDI instrument. Audio from an external MIDI instrument can be sent to an external mixer or monitored through your Pro Tools au­dio interface (using either an Instrument track or Auxiliary track).
If you are using an external MIDI instrument, it must be connected to MIDI ports that are recog­nized by your computer. These ports can be on a Pro Tools interface that has MIDI ports (such as an Mbox as an M-Audio MIDISPORT).

Pro Tools Reference Guide10
Signal paths for external MIDI instruments
To actually hear an external MIDI instrument, you need to connect its audio outputs to a mix­ing console or connect it to one of the audio in­puts of your Pro Tools audio interface.

Synchronization

When you are working with multiple time­based systems, such as Pro Tools and an external deck, you want both systems to be synchro­nized. Synchronization is where one system out­puts time code or MIDI Beat Clock and another device synchronizes to or follows that time code or MIDI Beat Clock so that they work together according to the same clock source. Pro Tools can be synchronized to other devices (or other devices can be synchronized to Pro Tools) using SMPTE/EBU time code or MIDI Time Code.
Just as each Pro Tools system has unique hard­ware features, each MIDI device has its own fea­tures (and limitations) as to the number of voices and instruments it can play at one time. Refer to the device’s documentation for infor­mation on its capabilities.
MIDI In Pro Tools
Pro Tools provides powerful MIDI sequencing capabilities. You can record, enter, edit, and play back MIDI data on Pro Tools Instrument and MIDI tracks. These actions can be done in the Edit window, the MIDI Editor window, the Score Editor window, and the MIDI Event List.
MIDI data in Pro Tools can be anything from MIDI note data (note number, on/off, velocity) to System Exclusive (Sysex) messages. MIDI data can be recorded or played back from both exter­nal MIDI devices with a MIDI interface (like the M-Audio MIDISPORT or Mbox 2) and other MIDI software (such as instrument plug-ins and ReWire client applications).
For more information on different SMPTE/EBU formats, and other concepts related to time code, refer to the Pro Tools Sync & Surround Concepts Guide.

Surround Sound

Surround sound simply means having one or more speakers with discrete audio signals (chan­nels) placed behind the listener in addition to the typical stereo pair.
There are multiple types of surround formats in use (from three-channel LCR to 7.1, which has eight channels).
The most common surround format is 5.1, which refers to having 5 speakers and a sub­woofer (the “.1”). 5.1 is used in movie theaters and home entertainment systems. Additionally, most DVDs are mixed to 5.1. The standard speaker placement for 5.1 for surround monitor­ing is stereo left and right speakers, and an addi­tional center speaker in front, two more stereo left and right speakers in the rear, and the sub­woofer on the side.

There are different session file icons for each type of Pro Tools system software.
Session file icons

Pro Tools Sessions

When you start a project in Pro Tools, you create a session. Some basic elements of sessions are ex­plained in this section.
Session File
A session file is the document that Pro Tools cre­ates when you choose File > New Session and configure a new session. Pro Tools can open only one session file at a time. The session file is named with a .ptf (Pro Tools file) extension. Ses­sion files contain maps of all elements associ­ated with a project, including audio files, MIDI data, and all your edit and mix information. It is important to realize that a Pro Tools session file does not contain any media files (audio or video). Instead, it references audio, video, MIDI, and other files. You can make changes to a ses­sion and save those changes in a new session file. This lets you create multiple versions of a session or back up your editing and mixing work.
Although there are different session file icons, session files may be opened by the other types of Pro Tools system software (with certain restric­tions). See “Opening a Session” on page 138.
When a session is transferred to a different Pro Tools system, its session file icon changes to the icon type of the destination system.
Tracks
Pro Tools tracks are where audio, MIDI, video, and automation data are recorded and edited. Pro Tools tracks also provide audio channels for routing internal busses, and physical inputs and outputs for audio and MIDI.
Pro Tools Reference Guide12
Pro Tools provides multiple types of tracks: audio, Auxiliary Input, Master Fader, VCA Mas­ter, MIDI, Instrument, and video.
Video tracks support QuickTime movies (all Pro Tools systems) and VC-1 video files (Win­dows Vista only). Additionally, Avid video is supported on Pro Tools HD or Pro Tools LE with DV Toolkit 2 software with an Avid video pe­ripheral. An individual video track can play back only one type of video at a time.
Audio track in the Edit window (stereo track shown)
MIDI track in the Edit window
Video track in Frames view
Audio, MIDI, Instrument, and video track data can be edited into regions or repeated in differ­ent locations to create loops, re-arrange sections or entire songs, or to assemble tracks using ma­terial from multiple takes.
Auxiliary Input tracks can route internal audio busses or physical inputs to internal busses or physical outputs. Auxiliary Inputs are typically used for audio effects busses, audio throughput (monitoring), and submixing.
Master Fader tracks provide controls for physical audio output channels, including the volume level of your mix, panning, and plug-in inserts.
Audio, Auxiliary Input, Master Fader, and In­strument tracks can be mono, stereo, or multi­channel (Pro Tools HD and Pro Tools LE with the Complete Production Toolkit option only). When creating a new track, select from the list of channel formats supported by your system.
Voices
In Pro Tools, voices are unique, discrete audio streams that can be routed to and from Pro Tools audio tracks physical audio outputs and inputs on your Pro Tools audio interfaces. The audio paths to and from Pro Tools software routed to Pro Tools hardware use voices. If you exceed the number of available voices in your system, you have effectively exceeded the avail­able number of audio paths.
Typically, each audio channel for each track in your Pro Tools session uses a single voice. So, for a mono audio track, a single voice is used; for a stereo audio track, two voices are used. When using Punch Recording, two voices are needed for every single audio channel (one for playback and one for recording on punch in and out). In some situations, with Pro Tools|HD systems, more than one voice may be necessary for a sin­gle channel (such as when using host processing on a TDM bus).
VCA Master tracks (Pro Tools HD only) provide control of tracks in a Mix Group that has been assigned to the VCA Master.
Chapter 2: Pro Tools Concepts 13
Voices can be allocated dynamically (with all Pro Tools systems, any available voices are auto­matically assigned as they are needed) or explic- itly (with Pro Tools HD only, you can explicitly assign audio channels to specific available voices to ensure that audio on that channel is al­ways voiced).
Audio files for each session are stored in a folder named “Audio Files.” Audio files are listed in the Pro Tools Region List and can appear in an au­dio track. A section of an audio file can be de­fined as a region. See “Regions” on page 15.
MIDI Files
On Pro Tools|HD systems, the number of avail­able voices is dependent on the amount of ded­icated DSP processing in your system (see “Pro Tools|HD System Playback, Recording and Voice Limits” on page 34).
On Pro Tools LE systems, the full number of available voices for your system may be limited by the host processing power of your computer (see “Pro Tools LE System Capabilities” on page 42).
For more information about voicing in Pro Tools, see “Track Priority and Voice As­signment” on page 206.
Media Files
Pro Tools sessions create, import, export, and reference media files. Media files are audio, MIDI, and video files. Audio and video media files are stored separately from the Pro Tools ses­sion file. MIDI data is stored in the session file.
Audio Files
When you record or enter MIDI into a Pro Tools session, all MIDI data is stored in the Pro Tools session file. You can import and export MIDI files to and from Pro Tools sessions, but MIDI recorded or otherwise created in a Pro Tools session does not automatically create new MIDI files.
Video Files
When you record or import video into a Pro Tools session, all video data is stored as the corresponding video file type (such as Quick­Time). Video files can be created in (or copied to) the Video Files folder in the session folder. However, in most cases, Pro Tools references video files that have been captured by another application, such as Avid Media Composer.
When you record audio into a Pro Tools session, audio files are created.

Pro Tools Reference Guide14
Regions
and MIDI. A region can also have associated au­tomation data. In Pro Tools, regions are created from audio files or MIDI data, and can be ar­ranged in audio and MIDI track playlists. Re­gions can also be grouped (a region of regions) and looped (repeated).
Audio region
MIDI region
Video region (Frames view)
Region group (Mixed audio and MIDI multitrack region group)
A region is a segment of audio, MIDI, or video data. A region could be a drum loop, a guitar riff, a verse of a song, a recording take, a sound ef­fect, some dialog, or an entire sound file. Re­gions are especially useful for arranging audio
Playlist
Playlist selector pop-up menu
A playlist is a sequence of regions arranged on an audio, MIDI, or video track. Tracks have edit playlists and automation playlists.
On audio tracks, an edit playlist tells the hard disk which audio regions to play in what order. For example, you can have separate audio re­gions for a song introduction, the first verse, the first chorus, and so on. You can also use the same audio region to access the same piece of audio multiple times at different locations and not use additional disk space. Different versions of the same original audio can be used in differ­ent places and have different effects applied. On MIDI and Instrument tracks, edit playlists can store multiple MIDI sequences (or perfor­mances) on a track.
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.
Chapter 2: Pro Tools Concepts 15
You can create any number of alternate edit playlists for a track. This lets you assemble differ­ent versions of performances or edits on a single track and choose between them from the Play­lists menu on the track.
Each audio, Auxiliary Input, Instrument, Master Fader, and VCA track also has a single set of au­tomation playlists. Automation playlists can in­clude volume, pan, mute, and each automation­enabled control for the insert and send assign­ments on that track.
MIDI controller data on Instrument and MIDI tracks is always included as part of the track playlist.
Channel
The term channel is used to describe several re­lated components of a Pro Tools system. The first example of channel refers to a physical in­put or output of your Pro Tools system. For ex­ample, a 96 I/O audio interface provides up to 16 channels of audio input and output to a Pro Tools|HD system, while an Mbox 2 audio in­terface provides up to four inputs and two out­puts.
The second use of the term channel refers to a channel strip in the Pro Tools Mix window. Each track in a Pro Tools session has a corre­sponding channel strip in the Mix window.
Audio and MIDI channel strips have similar controls, but those controls have slightly differ­ent effects. For example, audio, Auxiliary Input, and Instrument track 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 se­lected MIDI instrument.
The term ‘MIDI channel’ also describes a separate aspect of MIDI operation. See “MIDI” on page 9.

Signal Routing
Pro Tools provides software-based mixing and signal routing controls for audio and MIDI. These controls are located in the Mix window. Some of these controls can also be accessed from the Edit window.
A common audio signal routing task is to sub­mix multiple tracks to a single channel strip (such as an Auxiliary Input) for shared process­ing and level control. The following example shows two audio tracks submixed to a stereo Auxiliary Input.
Channel strip in the Mix window (audio track)
Submixing to an Auxiliary Input
Chapter 2: Pro Tools Concepts 17
Signal Routing Options
Signal routing options include the following:
Track Input and Output (I/O) Controls The most basic type of signal routing is track input and output. A track needs to have an assigned input path to record audio, and an assigned mapped 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 Input and Master Fader Tracks Auxil­iary Inputs can be used as returns, submixers, and bus masters. Master Fader tracks are used as bus and output master level controls. Both Aux­iliary Input and Master Fader tracks can have plug-in and hardware inserts.
MIDI Tracks MIDI tracks are generally used for routing MIDI from internal or external sources to external MIDI devices. MIDI data can also be routed to plug-ins on Auxiliary Inputs or Instru­ment tracks.
Instrument Tracks Instrument tracks are the pri­mary way to route MIDI to an instrument plug­in and then route the plug-in’s sound to out­puts, sends and busses, or other inserts. Instru­ment tracks can also be used to send MIDI to and monitor audio from external MIDI devices.
Sends Sends route audio from tracks to hard­ware outputs, or to internal busses that are in turn routed to other tracks within Pro Tools. MIDI, Master Fader, and VCA Master tracks do not have sends.
Plug-In and Hardware Inserts Plug-In processing occurs completely within the Pro Tools system. Hardware inserts use audio interface inputs and outputs for traditional insert routing to and from external effects and other devices. MIDI and VCA Master tracks do not have inserts.
Instrument Plug-Ins Instrument plug-ins are dif­ferent from processing plug-ins in that they gen­erate audio rather than process the audio signal from a track’s audio input or from hard disk. Instrument plug-ins are typically played by MIDI.
Paths Paths are any routing option in Pro Tools, including internal or external inputs, outputs, busses, and inserts. Pro Tools lets you name these paths, and these path names appear in the Audio Input and Output Path selectors and other menus. For more information, see Chapter 6, “I/O Setup.”
Mixing Formats Sessions can include combina­tions of mono, stereo, and greater-than-stereo multichannel format tracks, busses, inputs, out­puts, and inserts. Greater-than-stereo multi­channel formats are supported with Pro Tools HD, and Pro Tools LE with the Com­plete Production Toolkit option only.
Grouping and VCA Tracks Tracks can be grouped together for mixing so that their relative mix settings are maintained when changing a mix setting for any track in the group (for example, changing the volume of one track affects the volume of all the other tracks in the group). VCA Master tracks (Pro Tools HD only) control the relative mix settings for all tracks within the selected group.
Pro Tools Reference Guide18

Tick-Based and Sample-Based Time

Pro Tools lets you set any track timebase to either sample-based or tick-based. You can also set the Timeline to be viewed as tick-based or sample-based.
Audio in Pro Tools is sample-based by default. This means that if an audio region is located at a particular sample location, it will not move from that location if the tempo changes in the session—though its Bar|Beat location will change.
MIDI data in Pro Tools is tick-based by default. This means that if a MIDI region is located at a particular Bar|Beat location, it will not move from that Bar|Beat location if the tempo changes in the session—though its sample location will change.
You can select whether a track is sample-based or tick-based when it is created, or change time­bases later.
Sample-Based Audio and MIDI
With a sample-based audio track, all regions in the track have an absolute location on the Time­line. Regions stay fixed to the sample time, re­gardless of where tempo or meter changes occur in a session.
If you make a MIDI track sample-based, all MIDI events in the track have an absolute location on the Timeline. MIDI events stay fixed to sample time, regardless of any tempo or meter changes in a session.
Tick-Based Audio and MIDI
Tick-based audio is fixed to a Bars|Beat location, and moves relative to the sample Timeline when tempo and meter changes occur. However, MIDI events and tick-based audio respond differently to tempo changes with respect to duration. MIDI note events change length when tempo or meter is adjusted, while audio regions do not (unless Elastic Audio is enabled). When Elastic Audio is not enabled on an audio track, meter and tempo changes affect only the start point (or sync point) for each audio region in a tick­based track. If Elastic Audio is enabled on an au­dio track, tempo changes apply Elastic Audio processing, which changes the duration of the audio region.
Elastic Audio
Elastic Audio provides real-time and non-real­time (rendered) Time Compression and Expan­sion (TCE) of audio. Tick-based Elastic Audio tracks actually change the location of samples according to changes in tempo. The audio stretches or compresses to match changes in tempo. Elastic Audio also provides high-quality non-real-time region-based pitch shifting.
Pro Tools Elastic Audio uses exceptionally high­quality transient detection algorithms, beat and tempo analysis, and real-time or rendered TCE processing algorithms. Elastic Audio lets you quickly and easily tempo conform and beat match audio to the session’s Tempo ruler. It also provides an unprecedented degree of control over transient detection and TCE processing on an event-by-event basis.
Chapter 2: Pro Tools Concepts 19
With Elastic Audio, Pro Tools analyzes entire au­dio files for transient “events.” For example, an event can be a drum hit, a sung note, or chord played by a guitar. These detected events can then serve as control points for “warping” the audio. Pro Tools can warp (TCE) audio events automatically, such as when automatically con­forming audio to the session tempo or quantiz­ing audio events, or you can warp audio manu­ally using the standard editing tools with the audio track set to Warp view.
Elastic Audio is useful in several common work­flows: working with loops, correcting perfor­mances, remixing, beat and pitch matching, and sound design and special effects.
In order to free up needed DSP resources,
Pro Tools allows for certain items (such as tracks and inserts) to be manually made inactive. Inac­tive elements are viewable, editable, and re­tained within the session. See “Active and Inactive Items” on page 20.
All Pro Tools systems provide flexible voice
options for audio tracks, to help maximize use of available voices in your system. For more in­formation on voice management and options, see “Voice Borrowing” on page 209.
Active and Inactive Items
Pro Tools lets you make certain items (such as tracks and inserts) inactive, in order to free up DSP resources and mixer connections.

System Resources

Track count, plug-in processing, signal path and routing options, and voice availability are ulti­mately limited by the combined resources avail­able from the host computer and from your Pro Tools hardware.
Pro Tools provides several ways to manage and conserve resources to maximize the perfor­mance of your system. As you begin working with Pro Tools sessions and tracks, you can take advantage of the following features to extend the effectiveness of your available DSP and other resources:
Pro Tools lets you adjust the performance of
your system by changing system settings that af­fect its capacity for processing, playback, and re­cording. See “Configuring Pro Tools System Settings” on page 50.
Items in Pro Tools that can be made inactive include the following:
• Audio, Auxiliary Input, Master Fader, VCA Master, and Instrument tracks
• Track Inputs and Outputs
•Sends
• Side-chain inputs
•Plug-Ins
• Hardware inserts
• Paths (session-wide)
MIDI tracks cannot be made inactive.
Side-chain inputs support direct active and inactive switching, but do not follow switching all or all selected side-chain inputs.
Pro Tools Reference Guide20
In addition to manually setting Active and Inac-
Active Inactive plug-in
Inactive track
tive modes, Pro Tools automatically makes items inactive if there are insufficient or un­available resources.
When active, items are fully engaged and opera­tional.
When inactive, items are silent and off, although most associated controls can still be adjusted. Different inactive items affect available system resources in specific ways, as follows:
Plug-Ins When a plug-in is inactive on a track, its DSP is made available for other plug-ins and pro­cessing. Plug-In assignments can be made inac­tive manually or automatically (see “Automatic and Manual Inactive Mode” on page 22).
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 22).
Display of Inactive Items
When items are inactive, their names appear in italics, and their background becomes dark gray. When a track is inactive, the entire channel strip is grayed out.
Tracks When a track is made inactive, its voices become available for another track. Inactive mono tracks free up one voice; inactive stereo and multichannel tracks free up one voice per channel. Additionally, when an audio, Auxiliary Input, Instrument, or Master Fader track is made inactive, its plug-ins, inserts, sends, and I/O assignments become inactive, and the associ­ated DSP used is freed up for use elsewhere in the session.
Active and inactive plug-ins, sends, and tracks
Chapter 2: Pro Tools Concepts 21
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.

DigiBase

DigiBase is a database management tool for Pro Tools. DigiBase expands upon basic Pro Tools search and import capabilities by pro­viding powerful tools to manage your data both inside and outside of your sessions, on any hard drive connected to the system.
Automatically Inactive Items
When opening a session, it is possible that not all signal paths, plug-ins, or audio interfaces used in the session will be available as defined on the current system. When opening a session, sufficient voices may also be unavailable if the session was created on a different Pro Tools sys­tem type (for example, opening a session created on a Pro Tools HD system on a Pro Tools LE sys­tem).
Whenever this occurs, the session will open as it was last saved. All items that are unavailable, or cannot be loaded due to insufficient resources, are made inactive.
Manual Inactive Switching
You can manually apply Active or Inactive modes to manage system resources. By making an item inactive, its associated resources are made available elsewhere in the session.
A database is a way of organizing data such that it can easily be searched, sorted, managed, and utilized. Your checkbook is an example of a da­tabase file. For every check you write, you enter a new record. That record contains information about the check, such as when you wrote it, to whom you wrote it, and for what amount. This information is written in specific columns, or fields. Everything you need to know (the check’s metadata) is there, even though the check itself is not.
DigiBase browsers let you search, sort, and mange these databases by volume or catalog (DigiBase Pro only). You can use DigiBase browsers not only to organize your Pro Tools sessions and media files (audio, MIDI, and video), but also to audition and import by drag and drop.
For more information about DigiBase, see “DigiBase” on page 247.

Configuring Pro Tools System Settings

Pro Tools lets you adjust the performance of your system by changing system settings that affect its capacity for processing, playback, and recording. These system settings are available in the Playback Engine (Setup > Playback Engine).
Playback Engine for Pro Tools|HD system
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.
Pro Tools Reference Guide50
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) con­trols the size of the buffer used to handle host processing tasks such as processing with Real­Time AudioSuite™ (RTAS) plug-ins.
• Lower Hardware Buffer Size settings are useful for improving latency issues in certain record­ing situations or for improving certain system performance problems:
• On all Pro Tools systems, lower settings re­duce RTAS MIDI-to-audio latency (such as when playing an RTAS virtual instrument live and monitoring the instrument’s out­put). Lower settings can also improve screen response or the accuracy of plug-in and mute automation data.
• On Pro Tools LE systems, lower settings re­duce all input-to-output monitoring la­tency on any record-armed tracks or Auxiliary Input tracks with live inputs.
• On Pro Tools|HD systems, lower settings re­duce monitoring latency that occurs on tracks that have one or more RTAS plug-ins. Lower settings can also improve the accu­racy of MIDI track timing on systems with­out a MIDI interface that supports time stamping. Lower settings also improve MIDI track timing on tracks using MIDI virtual instruments that do not support time stamping.
• Higher Hardware Buffer Size settings are use­ful for sessions that are using more RTAS plug­ins for playback. These settings allow for more audio processing. They can also be useful to reduce errors on machines that require a higher buffer size.
To change the Hardware Buffer Size:
1 Choose Setup > Playback Engine.
2 From the H/W Buffer Size pop-up menu, select
the audio buffer size, in samples.
3 Click OK.
Host Processors
The Host Processors setting determines the number of processors in your computer allo­cated for RTAS (Real-Time AudioSuite) plug-in processing and other host processing tasks.
With computers that have multiple processors, or that feature multi-core processing or hyper­threading, this setting lets you enable multipro­cessor support for host processing tasks. Used in combination with the CPU Usage Limit setting, the Host Processors setting lets you control the way host-processing tasks are handled by the system.
For example:
• For sessions with large numbers of RTAS plug­ins, you can allocate 2 or more processors to RTAS processing and set a high CPU Usage Limit.
• For sessions with few RTAS plug-ins, you can allocate fewer processors to RTAS processing and set a low CPU Usage Limit to leave more CPU resources available for automation accu­racy, screen response, and video.
• Increase these settings to accommodate TDM to RTAS plug-in conversion. Conversely, de­crease these settings if you are only using TDM plug-ins or are converting RTAS plug-ins to TDM. TDM/RTAS conversion can be desir­able during recording, depending on latency, voicing needs, and record-monitoring capa­bilities of the specific TDM and RTAS plug-ins.
Chapter 5: System Setup 51
• Depending on the importance of video and overall screen response, and on the density of automation being employed, try different combinations of Host Processors and CPU Us- age Limit settings to achieve the best results. For example, to improve screen response in a medium-sized session using a moderate num­ber of RTAS plug-ins, try reducing the number of RTAS plug-ins, but keep the CPU Usage Limit set to the maximum (up to 99% on a single processor system).
To set the number of Host Processors:
1 Choose Setup > Playback Engine.
2 From the Host Processors pop-up menu, select
the number of available processors you want to allocate. The number of processors available var­ies depending on how many processors are available on your computer:
• Select 1Processor to limit host processing for Pro Tools to one CPU in the system.
• Choose 2 Processors to enable load balanc­ing across two available processors for Pro Tools host processing tasks.
• On systems running four or more proces­sors, choose the number of processors for Pro Tools host processing tasks.
3 Click OK.
System Usage Window and Host Processing
The System Usage window (Windows > System Usage) displays the combined amount of host
processing occurring on all enabled processors with a single indicator, regardless of how many processors are available in the system. If the Sys­tem Usage Window shows that you are at the limit of available resources, increase the number of Host Processors and adjust the CPU Usage Limit setting. (For more information, see “Sys­tem Usage” on page 68.)
CPU Usage Limit
The CPU Usage Limit setting controls the per­centage of CPU resources allocated to Pro Tools host processing tasks. Used in combination with the Host Processors setting, the CPU Usage Limit setting lets you control the way Pro Tools tasks are carried out by the system.
•Lower CPU Usage Limit settings limit the effect 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 RTAS plug-ins.
The maximum available CPU Usage Limit de­pends on the number of processors in your com­puter and on the number of processors you spec­ify for host processing. This value can range from 85% for single-processor computers (ex­cept for 003, 003 Rack+, 003 Rack, Digi 002, and Digi 002 Rack, which have a limit of 99%), and 99% for multiprocessor computers (which dedi­cate one entire processor to Pro Tools).
On multiprocessor computers, the maximum CPU Usage Limit is reduced when you use all your processors (as selected in the Host Processing pop-up menu). For example, on dual-processors, the limit is 90%. On four-processor computers, the limit is 95%.
Increasing the CPU Usage Limit may slow down screen responses on slower computers.
Pro Tools Reference Guide52
To change the CPU Usage Limit:
1 Choose Setup > Playback Engine.
2 From the CPU Usage Limit pop-up menu, select
the percentage of CPU processing you want to allocate to Pro Tools.
3 Click OK.
Error Suppression Options
Ignore Errors During Playback/Record When en-
abled, Pro Tools continues to play and record even if the host processing requirements exceed the selected CPU Usage Limit. This can result in pops and clicks in the audio, but does not stop the transport.
Host Engine (Error Suppression)
The Host Engine options determine error report­ing during playback and recording. This is espe­cially useful when working with instrument plug-ins.
On Pro Tools|HD systems, there is a single Host Engine option. On Pro Tools LE systems, there are two Host Engine options.
• Enable error suppression only if you are expe­riencing frequent errors that are interrupting your creative workflow. When error suppres­sion is enabled, you can experience a degrada­tion of audio quality. However, this may be acceptable in order to avoid interrupting play­back and recording when working with in­strument plug-ins.
• Disable error suppression when you need to ensure the highest possible audio quality, such as for a final mix.
To enable error suppression:
1 Choose Setup > Playback Engine.
2 Select Ignore Errors During Playback/Record.
3 If available, you can also select Minimize Addi-
tional I/O Latency.
4 Click OK.
Minimize Additional I/O Latency (Pro Tools LE and M-Powered Only) When enabled, any additional
latency due to suppressing errors during play­back and record is minimized to 128 samples. Suppressing errors requires at least 128 samples of additional buffering on some systems. If this option is disabled, the buffer is half the H/W Buf- fer Size, or at least 128 samples (whichever is greater). If you are on an older, slower computer, you may want to disable this option to avoid ad­verse performance.
This option is only available if the Ignore Errors During Playback/Record option is enabled and the Pro Tools system you are using requires ad­ditional buffering for error suppression, as fol­lows:
•Windows:
•Mbox 2 Pro
• All Pro Tools M-Powered systems
•Mac:
• 003, 003 Rack+, and 003 Rack
•Eleven Rack
•Mbox 2
•Mbox 2 Pro
• Mbox 2 Mini
• Mbox 2 Micro
• Digi 002 and 002 Rack
• All Pro Tools M-Powered systems
Chapter 5: System Setup 53
Number of Voices
(Pro Tools HD Only)
On Pro Tools|HD systems, the Number of Voices setting lets you control the number of available voices and how those voices are allocated to DSPs in your system. For example, the default number of voices on a Pro Tools|HD 1 system is 48 voices, using one DSP (at sample rates of
44.1 kHz or 48 kHz).
Changing the number of voices affects DSP usage, the total number of voiceable tracks, and overall system performance.
Depending on the session sample rate and the number of Pro Tools|HD cards in your system, there are different choices for voice count. For voice limits on different Pro Tools|HD systems, see “Pro Tools|HD System Playback, Recording and Voice Limits” on page 34.
To change the Number of Voices and DSP to allocate for voicing:
1 Choose Setup > Playback Engine.
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 as follows:
• Select minimum voice numbers if you are using high-bandwidth PCI or PCIe cards (such as video capture cards) along with your Pro Tools|HD cards. These settings place the lightest processing load on each allocated DSP chip, but generally require more DSP chips be dedicated to voicing and mixing (leaving fewer available for plug-ins).
• Select medium voice numbers when your Pro Tools|HD cards are in an expansion chassis, or when you are using other PCI or PCIe cards along with Pro Tools|HD cards. These settings generally provide an opti­mum balance between number of chips needed for voicing, and the processing load placed on each.
• Select higher voice numbers when your Pro Tools|HD cards are the only PCI or PCIe cards in your computer, or when you are using an expansion chassis to run higher track counts (such as 64 tracks at 96 kHz) and you want more voices per DSP (such as 16 voices per DSP at 96 kHz). These settings use fewer DSP chips for mixing (leaving more available for plug-ins) but place the highest processing load on each.
3 Click OK.
Pro Tools Reference Guide54
Sample Rate (Playback Engine)
(Pro Tools HD Only)
Delay Compensation Engine
(Pro Tools HD Only)
The Sample Rate setting in the Playback Engine determines the default sample rate when you create a new session. This setting is available only when there is no session open. Otherwise, the current session sample rate is displayed, but cannot be changed.
The Sample Rate setting can affect the number of available voices.
You can change the sample rate when creating a new Pro Tools session by selecting a different sample rate in the New Session dialog. (
page 136.)
See “Creating a New Session” on
You can also change the default Sample Rate in the Hardware Setup, as long as no session is open.
To make a copy of a session with a new sample rate, use Save Copy In.
To change the default Sample Rate in the Playback Engine:
1 With no session open, choose Setup > Playback
Engine.
2 Select the sample rate from the Sample Rate
pop-up menu.
3 Click OK.
The Delay Compensation Engine setting deter­mines how much DSP resources are dedicated to Pro Tools Delay Compensation, which manages DSP delays in the Pro Tools mixer.
Within a session, you can choose to enable or disable Delay Compensation (Options > Delay Compensation).
For more information, see “Delay Compen­sation” on page 886.
To configure the Delay Compensation Engine:
1 Choose Setup > Playback Engine.
2 From the Delay Compensation Engine pop-up
menu, select Short, Long, or None.
3 Click OK.
Delay Compensation Settings
There are three settings in the Playback Engine to dedicate DSP resources for Delay Compensa­tion:
None Allocates no DSP resources for Delay Com­pensation.
Short Allocates minimum DSP resources of De­lay Compensation for each channel. This is the most efficient setting. For sessions with only a few plug-ins that do not induce too much DSP­based delay, this setting should be sufficient.
Long Allocates maximum DSP resources for De­lay Compensation for each mixer channel. For sessions with a lot of plug-ins resulting in a large amount of DSP-induced delay, select this setting.
Chapter 5: System Setup 55
DAE Playback Buffer Size
The DAE Playback Buffer Size setting determines the amount of memory DAE allocates for disk buffers. In addition to levels, the DAE Playback Buffer Size shows values in milliseconds, which indicate the amount of audio buffered when the system reads from disk.
The optimum DAE Playback Buffer Size for most disk operations is 1500 msec; Level 2 (Default).
DAE Playback Buffer Size settings lower than 1500 msec; Level 2 (Default) may improve playback and recording initiation speed, as well as preview in context in DigiBase brows­ers. However, a lower setting may make it dif­ficult to play or record tracks reliably with sessions containing a large number of tracks or a high density of edits, or with systems that have slower or heavily-fragmented hard drives.
DAE Playback Buffer Size settings higher than 1500 msec; Level 2 (Default) allow higher track count, higher density of edits in a session, or the use of slower hard drives. However, a higher setting may increase the time lag when starting playback or recording, starting pre­view in context from DigiBase browsers, or cause a longer audible time lag while editing during playback.
Using a larger DAE Playback Buffer Size leaves less system memory for other tasks. The default setting of 1500 msec (Level 2) is recommended unless you are encountering –9073 (“Disk too slow or fragmented”) errors.
To change the DAE Playback Buffer Size:
1 Choose Setup > Playback Engine.
2 From the DAE Playback Buffer pop-up menu, se-
lect 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.
Cache Size
The Cache Size setting determines the amount of memory DAE allocates to pre-buffer audio for playback and looping when using Elastic Audio.
Minimum Reduces the amount of system mem­ory used for disk operations and frees up mem­ory for other system tasks. However, perfor­mance when using Elastic Audio features may decrease.
Normal Is the optimum Cache Size for most ses­sions.
Large Improves performance when using Elastic Audio features, but it also decreases the amount of memory available for other system tasks, such as RTAS processing.
Using a larger Cache Size leaves less system memory for other tasks. The default setting of Normal is recommended unless you are encountering -9500 (“Cache too small”) errors.
To change the Cache Size:
1 Choose Setup > Playback Engine.
2 From the Cache Size pop-up menu, select a
disk cache size.
3 Click OK.
Pro Tools Reference Guide56
System Memory Allocation
(Pro Tools HD Only)
When you start your computer, Pro Tools auto­matically reserves a portion of system memory for the DAE Playback Buffer. This reserved mem­ory is unavailable to other applications, even if Pro Tools is not running.
You can set Pro Tools to reserve only the mini­mum amount of required memory, so that more system memory is available to other applica­tions.
To minimize system memory allocation:
1 Choose Setup > Playback Engine.
2 Select the Minimize System Memory Allocation
option.
3 Click OK.
4 Do one of the following:
• On Mac systems, if prompted, enter your password, then restart your computer.
– or –
• On Windows systems, restart your com­puter.
The optimum Plug-In Streaming Buffer Size for most sessions is 250 ms; Level 2 (Default).
Plug-In Streaming Buffer Size settings lower than 250 ms; Level 2 (Default) reduce the amount of system memory used for sample playback and frees up memory for other sys­tem tasks. However, reliability of sample play­back may decrease.
Plug-In Streaming Buffer Size settings higher than 250 ms; Level 2 (Default) improve the re­liability of sample playback, but they also de­crease the amount of memory available for other system tasks, such as RTAS processing.
Using a larger Plug-In Streaming Buffer Size leaves less system memory for other tasks. The default setting of 250 ms (Level 2) is recommended unless you are experiencing problems with the reliability of streaming playback from disk.
To change the Plug-In Streaming Buffer Size:
1 Choose Setup > Playback Engine.
2 From the Plug-In Streaming Buffer Size pop-up
menu, select a buffer size.
3 Click OK.
Plug-In Streaming Buffer Size
(Structure Plug-In Only)
This setting appears in the Playback Engine only if the Structure sampler instrument plug-in is in­stalled on your system (this applies to Structure LE and Structure Free as well). The Plug-In Stream- ing Buffer Size determines the amount of mem­ory DAE allocates for streaming playback from disk with the Structure plug-in. This setting only affects playback if disk streaming is activated in Structure’s plug-in controls (see the AIR Virtual Instruments Guide for more information).
Optimizing the Plug-In Streaming Buffer Size
(Structure Plug-In Only)
This option appears in the Playback Engine only if the Structure plug-in is installed on your sys­tem. This option is useful when you are playing samples from the same drive that contains audio for the current session. When this option is se­lected, Pro Tools automatically optimizes the size of the Plug-In Streaming Buffer to facilitate disk access from both Pro Tools and Structure. The Plug-In Streaming Buffer Size pop-up menu is unavailable when this option is selected.
Chapter 5: System Setup 57
To set Pro Tools to automatically optimize the Plug-In Streaming Buffer Size:
1 Choose Setup > Playback Engine.
On Pro Tools HD, you can change the default Sample Rate in the Hardware Setup, or in the Playback Engine.
2 Select the Optimize for Streaming Content on
Audio Drives option.
3 Click OK.

Pro Tools Reference Guide58
Internal If you are recording an analog signal di­rectly into Pro Tools, you will usually use the Pro Tools Internal clock source.
External If you are transferring material into Pro Tools from an external digital device, or if you utilize a common house clock signal, you will synchronize Pro Tools to that digital device or common signal.
Depending on your audio interface, external op­tions can include AES/EBU [Encl], S/PDIF, Optical [Encl], AES/EBU 1–8, TDIF, ADAT, and Word Clock. For details, refer to the guide for your audio in­terface.
To select the Clock Source:
1 Choose Setup > Hardware.
2 Choose the clock source from the Clock Source
pop-up menu.
3 Click OK.
Your digital input device must be connected and powered on for Pro Tools to synchro­nize to it. If your input device is not powered on, leave the Clock Source set to Internal.
Configuring Digital Format and Hardware Routing
Configuring Pro Tools|HD Hardware Settings
On Pro Tools|HD systems, you configure Hard­ware settings for each audio interface connected to your system. For example, Pro Tools|HD sys­tems can have HD I/O, HD OMNI, HD MADI, 192 I/O, 192 Digital I/O, 96 I/O, or 96i I/O au­dio interfaces connected to Accel Core or HD Core and HD Accel or HD Process cards in the system. The HD I/O and HD OMNI can have additional interfaces attached. The 192 I/O, 192 Digital I/O, and 96 I/O can also have addi­tional interfaces attached (including older Pro Tools|24 MIX audio interfaces—Legacy I/Os—such as the 888|24 I/O, 882|20 I/O or 1622 I/O). For more information, see Chapter 4, “Pro Tools Systems.”
Configuring Audio Interfaces
The Hardware Setup includes additional settings for configuring the digital format and hardware routing for your system’s audio interfaces.
The following section outlines the configura­tion of a Pro Tools|HD system with one or more Pro Tools|HD interfaces (with one or more Leg­acy interfaces attached).
To configure a Pro Tools LE or M-Powered system, refer to the User Guide
that came
with your system.
HD OMNI, HD I/O, 192 I/O, 192 Digital I/O, 96 I/O, and 96i I/O audio interfaces support six­teen channels of simultaneous I/O and multiple I/O formats (such as analog, AES/EBU, ADAT Optical, S/PDIF, and TDIF). HD MADI supports up to 64 channels of MADI I/O.
The Main page of the Hardware Setup is where you define which physical inputs and outputs on your audio interface are routed to available inputs and outputs in Pro Tools. You can think of this window as a patchbay that allows you to route any of the inputs or outputs on your Pro Tools|HD audio interfaces to channel as­signments in the Pro Tools mixer.

6 Repeat the above steps for each additional au-
dio interface in your setup.
Hardware Setup for HD I/O, Main page
The Main page also provides controls for defin­ing whether Expansion Port or Legacy Port pe­ripherals are active (with 192 I/O, 192 Digital I/O, or 96 I/O primary audio interfaces only).
Additional pages are available to configure other controls for each audio interface (such as setting operating levels).
Identifying Audio Interfaces
If you have multiple audio interfaces of the same type connected to your system, before you make audio connections to them, you should confirm the identity of each interface. This en­sures that you choose the appropriate interface in the Peripherals list when you define its inputs and outputs in the Hardware Setup.
To identify audio interfaces in your system:
1 Choose Setup > Hardware.
2 From the Peripherals list, select an audio inter-
face connected to your system.
Use the Up and Down Arrow keys to scroll though the Peripherals list in the Hardware Setup.
Legacy I/Os must be initialized in the Pe­ripherals list before they can be identified. See “Configuring Legacy I/Os” on page 66.
To configure Pro Tools|HD audio interfaces:
1 Choose Setup > Hardware.
2 From the Peripherals list, select the
Pro Tools|HD audio interface connected to the first card in your system. This will be the inter­face at the top of the list.
3 Click the Main tab.
Press Command+Left or Right Arrow keys (Mac) or Control+Left or Right Arrow keys (Windows) to move though the different pages of the Hardware Setup.
4 From the Clock Source pop-up menu, select
the appropriate clock source for the interface.
In many cases, you will use Internal. The other choices are for resolving Pro Tools to external clock sources. Depending on your audio inter­face, Clock Source options can include: AES/EBU
[Encl], S/PDIF, Optical [Encl], AES/EBU 1–8, TDIF, ADAT, and Word Clock (optional Word Clock
rates are available when operating at higher sample rates).
3 Make sure the Main page is shown.

5 If you want to send clock output to other de-
vices attached to the audio interface, select the appropriate output from the Ext. Clock Output pop-up menu.
If the Legacy I/O Port is enabled (and not the Expansion I/O Port) then the Ext. Clock Output automatically switches to Slave Clock (256x sam­ple rate). To reset the Ext. Clock Output to Word
Clock, change the Port Settings back to Expansion I/O, then select the Legacy I/O in the
Peripherals list, and set it to No Interface in the Interface pop-up menu. (The HD OMNI, HD I/O, HD MADI, and 96i I/O do not support Legacy I/O.)
6 Select which digital I/O port on your audio in-
terface enclosure is active by selecting the corre­sponding option under Digital Format. Depending on the type of interfaces in your sys­tem, choices include AES/EBU, S/PDIF, and Opti- cal (S/PDIF). Selecting Optical (S/PDIF) resets the Optical I/O port (which is, by default, eight channels of ADAT Optical 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 From the Input and Output channel pop-up
menus, select 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, 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 HD 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 HD I/Os equipped with a second 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.

These controls mirror the routing controls found in the Hardware Setup—changes made to physical routing in one is always re­flected in the other.
The I/O Setup lets you label and map Pro Tools input, output, insert, and bus signal paths. The I/O Setup also provides important audition, me­ter, and surround settings. For more informa­tion, see Chapter 6, “I/O Setup.”
Routing a Pro Tools Output Pair to Multiple Destinations
Pro Tools channel pairs can be routed to multi­ple physical outputs on an audio interface through the Hardware Setup.
For example, if you assign Channels 1–2 to both outputs Analog 1–2 and Analog 3–4, when you send a signal to Pro Tools Channels 1–2, that signal will be routed simultaneously to both pairs of output ports on your audio interface.
Chapter 5: System Setup 67
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).

System Usage

Processing Bandwidth
To route a Pro Tools output channel pair to multiple audio interface output ports:
1 Choose Setup > Hardware.
2 From the Peripherals list, select an interface.
3 Click the Main tab.

up menu.
5 Control-click (Mac) or Start-click (Windows)
the same pop-up menu a second time to choose another available Output Port pair.
Only currently unassigned Output Port pairs are available.
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. 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. For more information, see “Routing Hardware I/O to Pro Tools Input and Output Channels” on page 83.
Meters in the System Usage window indicate how much of your system’s processing power is being used in processing audio, and when writ­ing and playing back automation.
Pro Tools HD, LE, and M-Powered have four common system activity meters:
PCI Displays the amount of PCI bus activity.
CPU (RTAS) Displays the amount of CPU pro-
cessing activity for RTAS processing.
CPU (Elastic) Displays the amount of processing activity for Real-Time Elastic Audio processing.
Disk Displays the amount of hard disk process­ing activity.
System Usage window (Pro Tools LE shown)
As these meters approach their limits, host pro­cessing and recording or playback of automa­tion data can be affected. If CPU or PCI Activity are high, a system error may occur. If Disk Activ­ity is high, Pro Tools may miss playback of some automation data during particularly dense peri­ods of activity, such as while using the Bounce to Disk command.
Pro Tools Reference Guide68
Pro Tools HD
System Activity
TDM Voices Allocated
TDM Time Slots Used
DSP Usage
With Pro Tools HD, there are additional meters:
TDM Voices Allocated Displays the total number of TDM voices that can be allocated and the number of voices currently allocated. This in­cludes all voices whether they are allocated ex­plicitly or dynamically, as well as any voices used for routing RTAS processing.
TDM Time Slots Used Displays the total number of TDM Time Slots available and the number of TDM Time Slots currently used.
DSP Usage (HD Core and HD Accel) Displays (in percent) how much of each DSP chip on each Pro Tools|HD card is currently being used for mixer configurations and TDM plug-ins.
To reduce processing load, do one of the following:
Reduce the density of automation in places
where it shows the most activity. For details, see “Thinning Automation” on page 953.
– or –
Turn off meters in Sends view, if enabled (by
deselecting Show Meters in Sends View in the Dis- play Preferences page). For details, see “Individ­ual Send Views and Meters” on page 871.
DSP Caching
(Pro Tools HD Only)
Pro Tools HD maintains a Plug-In and Mixer cache for allocated DSP when closing and open­ing sessions. While this has no effect on the time it takes to open the first session after you launch Pro Tools, it does result in being able to open and close all subsequent Pro Tools sessions much more quickly, especially when using the Revert To Saved command or when opening sim­ilarly configured sessions.
However, when using DSP caching, the System Usage window may not always accurately show the DSP resources your session is currently us­ing. For an accurate display of current DSP us­age, you can either disable DSP caching or purge the DSP cache.
System Usage window (Pro Tools HD 2 Accel shown)
To monitor the usage of resources during a Pro Tools session:

Chapter 6: I/O Setup 71
The I/O Setup provides a graphical representa­tion (cross-point matrix) of the signal routing for physical input and output paths for each con­nected audio interface. Like a virtual patchbay, I/O Setup controls let you route physical inputs and outputs on the audio interface to Pro Tools input and output channels. Some of these con­trols mirror the routing controls found in the Hardware Setup—changes made to physical routing in one is always reflected in the other.
The I/O Setup also provides controls for creating internal mix busses, and for creating and map­ping output busses.
Opening the I/O Setup
The I/O Setup can be opened from the applica­tion window (with a session closed), or from within a session (when a session is open).
To open the I/O Setup:
1 Make sure your audio interfaces are enabled
and configured properly in the Hardware Setup. See “Configuring Pro Tools Hardware Settings” on page 58.
Resizing the I/O Setup Dialog
To resize the I/O Setup dialog, do one of the following:
On Mac, drag the lower-right corner of the
window.
– or –
On Windows, drag any corner of the window.
Navigating in the I/O Setup
To scroll left or right in the I/O Setup:
Press Option+Page Up/Down (Mac) or
Alt+Page Up/Down (Windows).

Pro Tools Signal Paths

A signal path is a logical grouping of multiple in­puts, outputs, or busses that has a single name and (channel) format. The I/O Setup lets you de­fine and name paths according to the configura­tion of your studio and the needs of each proj­ect.
2 Choose Setup > I/O.
Closing the I/O Setup
To close the I/O Setup and save changes:
Click OK.
When you click OK, Pro Tools checks several set­tings for routing validity (to prevent feedback loops). If there are any overlapping or invalid settings, you will be required to correct them be­fore the I/O Setup will close. For more informa­tion, see “Valid Paths and Requirements” on page 93.
To close the I/O Setup without saving changes:
Click Cancel.
Pro Tools Reference Guide72
Main Paths and Sub-Paths
Paths in Pro Tools tracks and I/O Setup include main paths and sub-paths.
Main Paths Main paths are logical groupings of inputs, inserts, busses, or outputs. For example, a master stereo output path will include both its left and right channels.
Sub-Paths A sub-path represents a signal path
Stereo main path
Mono sub-paths
within a main path. For example, a default ste­reo output bus path consists of two mono sub­paths, left and right. Mono tracks and sends can be routed to either mono sub-path of the stereo output bus path.
It is especially useful to define and name sub-paths for complex mixing setups, such as a 5.1 Surround mix.
Paths in Session Tracks
In sessions, audio is routed using the track In­put, Output, Insert, and Send selectors. These se­lectors let you assign tracks to hardware inputs, output busses, 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 (see “As­signing Audio Inputs and Outputs to Tracks” on page 202).
Paths in the I/O Setup
The signal routing path choices available in a session are defined in the I/O Setup. For more information, see “I/O Setup Pages and Controls” on page 74.
Path Configurations and I/O Settings
Each Pro Tools session retains its path configu­rations as I/O Settings.
Each Pro Tools system can have a different path configuration, determined by:
• Whether it is a Pro Tools|HD, Pro Tools LE, or Pro Tools M-Powered system
• On Pro Tools|HD systems, the number and types of audio interfaces
• On Pro Tools|HD systems, and Pro Tools LE systems with Complete Production Toolkit, the installed Mixer plug-in (Stereo or Sur­round)
Certain aspects of the I/O Settings are saved with the session are loaded automatically when the session is opened. Other aspects of I/O Settings are saved with the system.
Unavailable items (including hardware, paths, or required resources) remain in the session as inactive items (see “Making Paths Active or In­active” on page 91).
When you create a new session, you can specify which I/O Settings to use (for example, the “Last Used” settings, or one of any custom I/O Set­tings files).
You can save and import I/O Settings files in the I/O Setup (see “Importing and Export­ing I/O Settings Files” on page 97).
Main and sub-paths in I/O Setup
Chapter 6: I/O Setup 73
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. These paths are avail­able in session tracks and are reflected in the I/O Setup. You can customize your I/O Setup config­uration at any time, according to the needs of each project (see “I/O Setup Pages and Controls” on page 74).
Default Settings Files
The default Stereo settings file is available on all Pro Tools systems, and provides stereo main paths, each with its own mono sub-paths.

I/O Setup Pages and Controls

Path Type Pages
The I/O Setup provides tabs to open pages for configuring the following I/O Settings.
To open any specific I/O Setup page:
Click the corresponding tab at the top of the
I/O Setup.
Press and hold the Command key (Mac) or the Control key (Windows) and use the Left or Right Arrow keys to cycle through the dif­ferent pages of the I/O Setup.
Multichannel settings files are available on Pro Tools|HD systems, and Pro Tools LE systems with Complete Production Toolkit. These set­tings provide specialized path definitions for surround mixing. For more information, see “Configuring Pro Tools for Multichannel Ses­sions” on page 1004.
Default Path Names
Default names for input, output, and insert paths are based on the type of system (such as specific Pro Tools LE systems) or type and num­ber of interfaces (such as Pro Tools|HD systems) you are using.
It is recommended that if you choose to cus­tomize your I/O Setup, configure the system­specific options first: Input, Output, Insert, Mic Preamps, and H/W Insert Delay. Then configure the Bus page as desired. Once you have configured your system, you should not need to change it unless you add or remove hardware (such as audio interfaces) from your system.

The Input page of the I/O Setup lets you create and map Pro Tools Input channels to receive au­dio from the physical inputs of your Pro Tools audio interfaces.
Configure input signal path names, formats, and source channel (analog or digital) on the In­put page. Multichannel input paths (stereo or greater) can have any number of sub-paths. In­put channels can have overlapping Input signal paths. Input names, channel widths, and physi­cal input mappings are saved with and recalled from the system.
The Output page of the I/O Setup lets you create and map Pro Tools Output channels to send au­dio to the physical outputs of your Pro Tools au­dio interfaces.
Configure output signal path names and for­mats on the Output page. Output channels can have overlapping Output paths. Output names, channel widths, and physical output mappings are saved with and recalled from the system.

Bus Page
Insert Page
The Bus page of the I/O Setup lets you create and edit internal mix busses and output busses. The Bus page also lets you map output busses to Out­put paths (as configured in the Output page of the I/O Setup).
Output bus paths are automatically mapped to output channels depending on the defined ses­sion output bus paths and the available system output channel paths. Output bus and internal mix bus names and channel widths are saved with and recalled from the session.
The Insert page of the I/O Setup lets you create and edit hardware insert signal paths for the Pro Tools mixer. Hardware inserts can route au­dio through an external device connected to parallel inputs and outputs of a Pro Tools audio interface. This lets you process audio on a track with a hardware insert in real time. Insert paths require audio interface inputs and outputs, and are determined by the configuration of the In­sert page in the I/O Setup for your system.

H/W Insert Delay Compensation
(Pro Tools HD Only)
If you do not know your hardware’s insert delay, see “Determining Your Hardware’s Insert Delay” on page 77.
Insert delay offsets only have an effect when the I/O is used for hardware inserts.
Determining Your Hardware’s Insert Delay
Check the documentation for your external hardware to see if it identifies the hardware la­tency, or use the following procedure in Pro Tools to determine the latency for hardware inserts.
To determine your hardware’s insert delay:
1 Ensure that Automatic Delay Compensation is
enabled (Options > Delay Compensation).
To compensate for the delay (latency) of any ex­ternal hardware devices (such as an effects unit) used in your session, you can set the amount of Hardware Insert Delay Compensation (in milli­seconds) for each external device. These times will be used by the Delay Compensation Engine to time-align input paths when the hardware in­sert is in use and Delay Compensation is en­abled.
Insert offset delay field
To set an insert delay offset:
Type a value, in milliseconds, in the field cor-
responding with the input where the hardware insert is connected.
2 Change your session’s Main Time Scale to
Min:Sec.
3 Create two tracks.
4 Route the tracks as follows: Route the output
of track 1 to the device’s inputs, then route the input of track 2 to the device’s outputs.
5 Place a short tone (or other sound with a de-
finitive beginning) on track 1.
6 Record enable track 2 and press Record Enable
and Play in the Transport window to play back the audio in track 1 and record it to track 2.
7 After recording, zoom in and measure the
difference between where the audio starts in track 1 and track 2. The difference is the value you would enter as your hardware’s insert delay offset.

Customizing I/O Settings

When you first install and configure your Pro Tools system, observe the following proce­dure for customizing your I/O Setup.
If you are using an HD OMNI in your Pro Tools|HD system, be sure to configure the Monitor page of the Hardware Setup for HD OMNI before configuring the I/O Setup. For more information, see the HD OMNI Guide.
To customize I/O Settings:
1 Open the I/O Setup (Setup > I/O).
2 In the I/O Setup, click the Input tab.
3 Create input paths and sub-paths with appro-
priate widths and mapping to physical inputs that match your studio configuration (see “Cre­ating New Paths” on page 85).
4 Name input paths and sub-paths as desired
(use the default naming scheme if you can).
7 Name output paths using standard industry
terminology, such as “Main,” “Cue A,” “Cue B,” and so on. This will facilitate session exchange with other Pro Tools systems (see “Recom­mended Output Path Naming Schemes” on page 87).
8 If you plan on using hardware inserts, click
the Insert tab and create insert paths with appro­priate widths and mappings to physical inputs and outputs matching your studio configura­tion. Name insert paths using standard industry terminology if possible, such as “Compressor,” “Reverb,” “EQ,” and so on.
9 If you are using hardware inserts, click the
H/W Insert Delay tab. Enter the correct insert de­lay in milliseconds for each input/output pair that you are using for hardware inserts. (See “H/W Insert Delay Compensation” on page 77.)
10 If you are using one or more PRE peripherals,
click the Mic Preamps tab and configure it ac­cordingly (see the PRE Guide).
11 Click the Bus tab.
12 Create internal mix bus and output bus paths
and sub-paths as desired. Ensure that output busses are mapped to the correct output paths (see “Output Busses” on page 94).
13 Click OK. You should not have to open the
I/O Setup again unless you add or remove hard­ware to or from your system.
5 Click the Output tab.
6 Create output paths with appropriate widths
and mapping to physical outputs that match your studio configuration.

Routing Hardware I/O to Pro Tools Input and Output Channels

The I/O Setup lets you define which physical ports on your audio interface are routed to avail­able input and output channels in Pro Tools. Use the Input and Output selectors in the I/O Setup to serve as a patchbay to route any of the
Chapter 6: I/O Setup 83
physical inputs or outputs of your audio inter­faces to the Pro Tools mixer. This mirrors the In- put and Output controls in the Hardware Setup (see “Configuring Pro Tools Hardware Settings” on page 58).
The Monitor path for HD OMNI is fixed and cannot be changed in the I/O Setup. The Monitor path for HD OMNI can be config­ured in the Monitor page of the Hardware Setup.
HD MADI Inputs and Outputs are “hard­wired” and cannot be changed.
To configure I/O routing in I/O Setup:
1 Choose Setup > I/O.
2 Click the Input or Output tab to display the cor-
responding 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
pair (such as Analog 1–2), to route to a Pro Tools channel pair (such as A 1–2) in the Path Name column on the left.
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. For example, if you assign both Ana­log 1–2 and Analog 3–4 interface outputs to Pro Tools Output pair 1–2, when you send a sig­nal to Pro Tools Outputs 1–2, that signal will be routed simultaneously to both pairs of output ports on your audio interface.
This lets you send the same signal (such as a ste­reo pair, a stem mix, or a multichannel mix) to multiple destinations (such as multiple master­ing devices).
The 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 93 for details.
Pro Tools outputs pairs can also be routed to multiple audio interface outputs in the Hard­ware Setup. For information, see “Routing a Pro Tools Output Pair to Multiple Destinations” on page 67.
