Pro Tools Reference Guide8
Chapter 2: Pro Tools Concepts
Before you begin to use Pro Tools, you may find
it helpful to review Pro Tools concepts.These
concepts are 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.
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.
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 or multiple times. In
addition, this re-arrangement is nondestructive,
meaning that the original recorded material is
not altered.
Chapter 2: Pro Tools Concepts 9
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 (see “DAE
Playback Buffer Size” on page 69
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 uses host (CPU) processing to provide
audio track recording, playback, mixing, and effects processing. Both Pro Tools and Pro Tools
HD use host processing to run RTAS
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 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.

The Playback Engine is also where you assign
dedicated resources for Automatic Delay Compensation.

Pro Tools System Settings” on page 62. See
also “System Resources” on page 21.

Core Audio
Apple’s Core Audio provides audio stream connectivity between software applications and audio hardware on Mac OS X. Pro Tools software
can use audio interfaces with supported Core
Audio drivers for playback and recording with
up to 32 channels of I/O.
Pro Tools MP supports qualified M-Audio
interfaces only. Refer to the compatibility
information on our website
(www.avid.com/compatibility).
ASIO
Steinberg’s Audio Stream Input/Output (ASIO)
provides audio stream connectivity between
software applications and audio hardware on
Windows. Pro Tools software can use audio interfaces with supported ASIO drivers for playback and recording with up to 32 channels of
I/O.
Pro Tools MP supports qualified M-Audio
interfaces only. Refer to the compatibility
information on our website
(www.avid.com/compatibility).
MIDI
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 connectors, labeled as either IN, OUT, or THRU. 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.
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 instrument sound. For example, bass on
channel 1, piano on channel 2, and drums on
channel 10. Similar to a multitrack tape recorder, a MIDI sequencer can record complex arrangements—even using only a single multitimbral keyboard.
Chapter 2: Pro Tools Concepts 11
MIDI Terms
The following are some basic MIDI terms:
MIDI Instrument A hardware MIDI device or
software instrument (such as an instrument
plug-in).
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 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.
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.
System Exclusive Data MIDI data commonly
used for sending and retrieving patch parameter
information for storage purposes.
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
Pro Tools Reference Guide12
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.
To actually hear an external MIDI instrument,
you need to connect its audio outputs to a mixing console or connect it to one of the audio inputs of your Pro Tools audio interface.
Common Misconceptions About
MIDI
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).
®
) or some other MIDI interface (such
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.
See 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) and other MIDI
software (such as instrument plug-ins and
ReWire client applications).
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
Signal paths for external MIDI instruments
Chapter 2: Pro Tools Concepts 13
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.
For more information on different
SMPTE/EBU formats, and other concepts
related to time code, see the Pro Tools Sync
& Surround Concepts Guide.
Surround Sound
(Pro Tools HD and Pro Tools Only)
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.
Pro Tools HD and Pro Tools with the Complete
Production Toolkit 2 option support mixing in
surround formats. In Pro Tools, each surround
format is considered to be a greater-than-stereo
multichannel format.
Pro Tools Sessions
When you start a project in Pro Tools, you create
a session. It can be helpful to understand the basic elements of a session.
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.
Session file icon (Pro Tools and Pro Tools MP)
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.
For information on fundamental surround
concepts, see the Pro Tools Sync & Surround
Concepts Guide.
Pro Tools Reference Guide14
Pro Tools provides multiple types of tracks:
audio, Auxiliary Input, Master Fader, VCA Master, MIDI, Instrument, and video.
Audio track in the Edit window (stereo track shown)
Video tracks support QuickTime movies (all
Pro Tools systems) and VC-1 video files (Windows 7 only). Additionally, Pro Tools supports
Avid video when using a supported Avid video
peripheral. An individual video track can play
back only one type of video at a time.
Audio, Auxiliary Input, Master Fader, and Instrument tracks can be mono, stereo, or multichannel (Pro Tools HD and Pro Tools with
Complete Production Toolkit 2 only). When
creating a new track, select from the list of channel formats supported by your system.
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.
VCA Master tracks (Pro Tools HD and Pro Tools
with Complete Production Toolkit 2 only) provide control of tracks in a Mix Group that has
been assigned to the VCA Master.
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).
Chapter 2: Pro Tools Concepts 15
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 “Region” on page 16.
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 “Playback, Recording, and Voice Limits with
Pro Tools HD” on page 44).
On all other Pro Tools systems, the full number
of available voices for your system may be limited by the host processing power of your computer (see “Pro Tools System Capabilities” on
page 53).
For more information about voicing in
Pro Tools, see “Track Priority and Voice Assignment” on page 233.
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 audio into a Pro Tools session,
audio files are created.
Audio file icons
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.
MIDI file icon
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

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
and MIDI. A region can also have associated automation data. In Pro Tools, regions are created
Pro Tools Reference Guide16
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).

Playlist
A playlist is a sequence of regions arranged on an
audio, MIDI, or video track. Tracks have edit playlists and automation playlists.
Playlist selector pop-up menu
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.
Region group (Mixed audio and MIDI multitrack region
group)
A playlist can be made up of a single region or
many separate regions. It can be made up of similar elements, such as regions from several different takes of a solo, or dissimilar elements, such
as several sound effects.
You can create any number of alternate edit
playlists for a track. This lets you assemble different versions of performances or edits on a single
track and choose between them from the Playlists menu on the track.
Chapter 2: Pro Tools Concepts 17
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, HD I/O provides up to 16 channels of audio input and output to a Pro Tools|HD or
Pro Tools|HD Native system, while an Mbox 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 11.

Track
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.
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.
The following example shows two audio tracks
submixed to a stereo Auxiliary Input.
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.
Submixing to an Auxiliary Input
Chapter 2: Pro Tools Concepts 19
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 7, “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 with the Complete
Production Toolkit 2 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 and Pro Tools
with Complete Production Toolkit 2 only) control the relative mix settings for all tracks within
the selected group.
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.
Pro Tools Reference Guide20
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.
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.
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.
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 62.
Chapter 2: Pro Tools Concepts 21
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 22.
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 236.
Active and Inactive Items
Pro Tools lets you make certain items (such as
tracks and inserts) inactive, in order to free up
DSP resources and mixer connections.
Items in Pro Tools that can be made inactive
include the following:
Side-chain inputs support direct active and
inactive switching, but do not follow
switching all or all selected side-chain
inputs.
In addition to manually setting Active and Inactive modes, Pro Tools automatically makes
items inactive if there are insufficient or unavailable resources.
When active, items are fully engaged and opera-
tional.
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 23).
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 23).
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.
Pro Tools Reference Guide22
Display of Inactive Items
Active Inactive plug-in
Inactive track
Automatic and Manual Inactive Mode
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.
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.
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 system
with an Mbox audio interface).
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
Active and inactive plug-ins, sends, and tracks
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.
Chapter 2: Pro Tools Concepts 23
DigiBase
AAF, MXF, and OMF
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.
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.
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 273.
(Pro Tools and Pro Tools HD Only)
Pro Tools lets you exchange audio, video, and
sequences with other AAF-, MXF-, and OMFcompatible applications (such as Avid editors).
Media Data (Media Files)
Media data represents raw audio or video material and is stored in individual media files. Every
time you record a piece of video or audio material into an application, you are creating a media
file. Audio media files hold samples (such as
44,100 or 48,000 samples per second of recording) while video media files use frames (24, 25,
or 30 frames per second of recording).
The size of each media file depends on how
much audio or video material it contains. For
example, a file containing ten minutes of high
resolution video might be approximately
2.16 GB in size, whereas a ten-minute audio recording at the might result in a 100 MB file. Media files tend to be large, since high quality audio and video signals are data intensive. Video
data generally requires considerably more storage than audio data.
Pro Tools Reference Guide24
Metadata
Metadata is used to describe the following:
• Information embedded in a media file. This
may include scene, take, sample rate, bit
depth, region names, the name of the videotape from which the media file was captured,
and even time code values.
• Information embedded in Pro Tools sessions
or other sequences, including what files are
used, where they appear in a timeline, and automation.
• For AAF or OMF sequences, metadata also includes information embedded in unrendered
AudioSuite™ effects (such as real-time EQ) on
Avid workstations. Pro Tools skips unrendered
effects on import. Rendered effects are media
files that can be imported into Pro Tools.
• For AAF or OMF sequences, information
about automation (clip-based gain or keyframe gain).
In the simplest case, only an AAF or OMF sequence is exchanged. If this sequence points to
existing media files, the size of the sequence file
is relatively small and the export/import process
is relatively fast.
AAF and OMF sequences can also have media
data embedded in them. This creates a single,
larger file that is slower to export and import,
but which may be easier to manage than thousands of files stored on different volumes.
AAF
AAF is a sequence file format. AAF sequences are
the best way to exchange projects and maintain
valuable metadata. An AAF sequence can refer to
OM F or MXF med ia f ile s, o r ha ve O MF a nd M XF
media files embedded within them. There is no
such thing as an AAF audio or video media file.
Pro Tools will import, play back, and export an
AAF sequence that either links to media files or
has audio embedded within it.
AAF, OMF, and MXF Basics
AAF and OMF files are mechanisms for storing
and retrieving media files and metadata so that
projects can be freely exchanged between different applications and platforms. MXF is a media
file format that can be used with AAF (but not
OMF) files.
Media data and metadata enable an application
that receives AAF and OMF sequence files (such
as Pro Tools) to automatically and quickly reassemble the composition. A simple metaphor for
this approach is that media data files are the
pieces of a puzzle and metadata is the set of instructions for assembling the puzzle.
When you import an AAF sequence with embedded audio into Pro Tools, the audio will be
extracted into mono tracks using the current
session’s audio file format.
Chapter 2: Pro Tools Concepts 25
MXF
MXF is a media file format. There are MXF video
files and MXF audio files, but there are no MXF
sequences. An AAF sequence may refer to or include MXF media files, but OMF sequences cannot refer to or include MXF files.
MXF file icon
Pro Tools can import and play back MXF audio
and video files created in Media Composer or
other Avid applications.
Pro Tools and Avid Terminology
Pro Tools and Avid use different terms to describe the same items. For example, a Pro Tools
session is equivalent to an Avid sequence. The following table lists common Pro Tools elements
and their Avid equivalents.
Pro Tools Avid (AAF or OMF)
sessionsequence
whole file regionmaster clip
regionsubclip
plug-insreal-time audio effects
volume automation gainAvid keyframe volume
Video files digitized in Pro Tools are technically in the MXF format, but are intended
only for use in Pro Tools and are not tested for
compatibility with other applications.
OMF
OMF is both a media file and sequence format.
OMF media files can be audio or video, and
Pro Tools can import and play back OMF audio
and video. Pro Tools can also export OMF audio,
but not OMF video.
Pro Tools can import and play back OMF audio
and video files created in Media Composer or
other applications.
An OMF sequence cannot reference or have
MXF media embedded within it.
Pro Tools can import an OMF sequence with
embedded audio, but not embedded video.
Pro Tools does not have a feature that compares to Avid clip-based gain. However, you
can use the Clip-Based Gain pop-up menu (in
the Import Session Data dialog) to map clipbased gain settings to Pro Tools breakpoint
automation, or to ignore clip-based gain entirely. See “Clip-Based Gain Pop-Up Menu”
on page 354.
Whole audio files in the Regions List normally appear in bold type. However, master
clip audio files imported from AAF or OMF
into Pro Tools will not appear in bold type (indicating regions) in the Pro Tools Regions List
even though they are audio files.

There are two types of AAF and OMF files: ones with embedded media, and ones with linked media.
Embedded Media
Exporting to AAF or OMF with embedded media results in one large AAF or OMF file containing both
the metadata and all associated media files.
When working with OMF embedded media or creating AAF embedded audio, Pro Tools limits file size
to 2 GB. However, you may be able to use Pro Tools to open an AAF embedded audio file larger than
2 GB if it was exported from another source.

Exporting AAF or OMF with linked media results in a single metadata file (.AAF or .OMF) and all associated media stored as separate files.
The main benefit to this approach is that fewer copies of media files may need to be made, so the export and import process can be much faster. Using this approach, it is less likely that you will encounter any file size limitations since the data is broken up into many smaller files.
The main disadvantage to this approach is that there are potentially many files (for example, one AAF
or OMF file and hundreds of media files) that must be transported between systems.

for example Mozilla Firefox, do not have
this limitation.
Understanding the Help
Display
The Help system uses the following main display areas:
• Help topics open in the right frame of the
• Navigation buttons and links for controlling
• Navigation tools (such as the Contents and
browser.
the Help display appear in the top area.
the Index) open in the left frame of the
browser.
Chapter 4: Using Help 35
Using the Help Navigation
Tools
How the Search Feature
Works
The left frame of the Help browser is the display
area for most of the Help system’s main navigation tools.
The Contents provides a list of links to the main
topics in the Help system. By default, the Contents tab shows only links to the first topic in
each chapter. This lets you quickly see the overall organization of the Help system. You can expand any chapter in the Contents to show the
main topics within that chapter, and you can
move to any of these topics by clicking its entry
in the Contents tab.
The Index provides an alphabetized list of entries similar to the index of a printed book. If
Java is enabled in your browser, the Index displays as a dynamic index where the listing
scrolls as you type a word in the text box. If you
do not have Java enabled in your browser, or if
your browser does not support Java implementations, a JavaScript version of the index displays which lets you scroll manually through
the entries.
The Search tab lets you search the entire text of
the Help system for one or more words and then
lists the topics that include those words.
The Help system’s search functionality has
a limitation when the Help system is running in the Safari browser. You can perform
one search successfully, but subsequent
searches do not return results until you clear
the Safari cache. You can do this by quitting
Safari and relaunching the Help, or by emptying the cache directly (select Safari >
Empty Cache, or use the Command+Option+E keyboard shortcut). Other browsers,
for example Mozilla Firefox, do not have
this limitation.
The Search feature provides the best combination of usefulness and speed. To use Search successfully, you should understand the following
aspects of the Search feature:
• The Search feature uses a database of valid
words. This database includes all words that
are significant for identifying topics and excludes all other words. When you type words
in the search text box, the system ignores any
invalid words that you have typed and
searches for valid words.
• The Search feature cannot search for words in
a certain order. For example, if you type “TIFF
graphics import” as a search entry, Search displays all topics that contains these three
words regardless of their location in the topic.
The results include topics where the three
words appear together as a phrase, and also
topics where the three words are scattered
throughout the topic.
• The Search feature cannot distinguish between words that are similar but not identical.
For example, if you type “capture” as a search
entry, Search displays topics that include that
word, but it does not find topics that include
related words such as “captures” or “capturing.” If a search for a word fails to produce
useful results, you might be more successful if
you search again using one of the related
words.
Remember that Help includes a comprehensive index. If Search does not produce useful
results for a particular topic, you can often
find the specific information you need
quickly by using the index.

Mono tracks of simultaneous playback refers to the
number of unique simultaneous playback and
record tracks on your system. Total voiceable tracks refers to the maximum number of audio
tracks that can share the available voices on
your system. (Mono tracks take up a single audio
track, while stereo tracks take up two tracks.)
Pro Tools 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 systems provide up to 32 channels of
I/O (depending on your audio interface), 128
Auxiliary Input tracks, a total of 256 internal
mix busses, and up to 10 inserts and 10 sends
per track (depending on your computer’s processing capacity). In addition, Pro Tools systems
support up to 64 Instrument tracks and 512
MIDI tracks. Pro Tools also supports a single
QuickTime video track.
For more information about the I/O
capabilities of your audio interface with
Pro Tools, see the documentation that
came with your audio interface.
If you open a Pro Tools session created on a
Pro Tools|HD system that contains more than
the number of tracks supported on the your
Pro Tools system, audio tracks beyond the system’s voiceable track limit will be automatically
set to inactive.
For details on transferring session material between Pro Tools|HD and Pro Tools systems, see
“Sharing Sessions Created on Different
Pro Tools Systems” on page 386.

or processing-intensive Pro Tools sessions.
Checking a Pro Tools|HD or
Pro Tools|HD Native System
with DigiTest
Before you use Pro Tools, you may want to run
the DigiTest diagnostic application to ensure
that all Pro Tools|HD cards in the system are recognized, installed in the proper order, and have
valid TDM FlexCable connections. See the Digi-Test Gui de for more information.
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).
Pro Tools Reference Guide62
Playback Engine for Pro Tools|HD system
Playback Engine for Pro Tools Mbox 2 system
Current Engine
(Pro Tools HD and Pro Tools Only)
In the Playback Engine dialog, Pro Tools lets you
select the audio engine for use with your audio
interfaces. The available options are determined
by which audio interfaces are connected and
have compatible drivers installed.
Changing the Current Engine setting can be useful if you have multiple audio interfaces connected to your computer with different routing
configurations in your studio, or if you want to
prepare a session for use with a specific interface
on a different system (for example you might
want to prepare a session created on your
Pro Tools|HD system for use with the built-in
audio on your Mac laptop).
To select which audio engine for Pro Tools uses:
1 Choose Setup > Playback Engine.
2 From the Current Engine selector, select your
audio interface:
• For Pro Tools|HD and Pro Tools|HD Native
systems, use the default setting of HD TDM
or HD Native.
• For supported Pro Tools and M-Audio audio interfaces (such as the Mbox Pro or ProFire 2626), selecting the name of the
corresponding interface uses the Direct I/O
engine for Pro Tools.
• For third-party audio interfaces with compatible CoreAudio (Mac) or ASIO (Windows), select the name of the
corresponding Core Audio (Mac) or ASIO
(Windows) compatible audio interface.
• On Mac systems, if you are using built-in
audio, select any of the available built-in
options for playback or select Pro Tools Ag-gregate I/O for simultaneous input and output with the built-in I/O hardware options.
When changing engines with a Pro Tools session open, Pro Tools must close and relaunch
the session to be able to initialize the new engine.
On Pro Tools|HD systems, changing engines requires that you quit and relaunch Pro Tools for
the new setting to take effect.
When changing engines on any Pro Tools
system, you may need to reset the default
I/O settings to match the selected audio interface.
Pro Tools Aggregate I/O
(Pro Tools on Mac Only)
On Mac systems using Core Audio, you can use
Pro Tools with the built-in audio inputs and
outputs on your Mac by selecting any of the
available built-in inputs and outputs, or by selecting the Pro Tools Aggregate I/O option for using a combination of built-in inputs and outputs simultaneously (for recording and
monitoring).
Selecting Pro Tools Aggregate I/O in the Playback
Engine (Mac only)
3 Click OK.
Chapter 6: System Setup 63
You can configure the Input and Output options for Pro Tools Aggregate I/O in the Mac Audio Setup, which can be accessed from the
Pro Tools Hardware Setup.
If you need simultaneous input (recording)
and output (playback and monitoring) with
Pro Tools using the built-in audio options
on Mac, use the Pro Tools Aggregate I/O option. If you only need to playback audio for
editing and mixing, select the appropriate
built-in audio output option.
Hardware Buffer Size
The Hardware Buffer Size (H/W Buffer Size) in the
Playback Engine controls the size of the buffer
used to handle host processing tasks such as processing with Real-Time 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 host-based Pro Tools 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 in the Playback Engine 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.
Pro Tools Reference Guide64
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.
• 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 82.)
CPU Usage Limit
The CPU Usage Limit setting in the Playback Engine 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.
Chapter 6: System Setup 65
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.
• 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.
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.
Host Engine (Error Suppression)
The Host Engine options in the Playback Engine
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 host-based Pro Tools systems,
there are two Host Engine options.
4 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.
Minimize Additional I/O Latency (Host-based
Pro Tools Systems and Pro Tools MP Systems
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 Buffer 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.
Pro Tools Reference Guide66
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 Pro and Mbox 2 Pro
• All Pro Tools systems with M-Audio devices
• Pro Tools MP systems
•Mac:
• 003 family devices
•Eleven Rack
• Mbox family devices
• Digi 002 and 002 Rack
• All Pro Tools systems with M-Audio devices
• Pro Tools Aggregate I/O
• Pro Tools MP systems
Number of Voices
(Pro Tools HD Only)
On Pro Tools|HD systems, the Number of Voices
setting in the Playback Engine 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 “Playback, Recording, and Voice Limits with
Pro Tools HD” on page 44.
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.
Chapter 6: System Setup 67
Sample Rate (Playback 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 160.)
Sample Rate in the Hardware Setup, as long
as no session is open.
See “Creating a New Session” on
You can also change the default
Delay Compensation Engine
The Delay Compensation Engine setting in the
Playback Engine determines how much DSP resources are dedicated to Pro Tools Delay Compensation, which manages DSP and host-based
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 958.
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.
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.
Pro Tools Reference Guide68
Delay Compensation Settings
There are three settings in the Playback Engine
to dedicate processing resources for Delay Compensation:
None Allocates no resources for Delay Compensation.
Short Allocates minimum resources for 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 DSP
and host–based delay, this setting should be sufficient.
Long Allocates maximum resources for Delay
Compensation for each mixer channel. For sessions with a lot of plug-ins resulting in a large
amount of DSP and host–based delay, select this
setting.
DAE Playback Buffer Size
The DAE Playback Buffer Size setting in the Playback Engine 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 in the Playback Engine
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.
Chapter 6: System Setup 69
To change the Cache Size:
1 Choose Setup > Playback Engine.
Plug-In Streaming Buffer Size
(Structure Plug-In Only)
2 From the Cache Size pop-up menu, select a

3 Click OK.
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.
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).
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.

Configuring Pro Tools|HD
Hardware Settings
On Pro Tools|HD and Pro Tools|HD Native systems, you configure Hardware settings for each
audio interface connected to your system (see
Chapter 5, “Pro Tools Systems.”)
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, HD OMNI, 192 I/O, 192 Digital I/O,
and 96 I/O can also have additional interfaces
attached using the Expansion port on each
interface.
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.
Configuring Pro Tools|HD Audio
Interfaces
HD OMNI supports up to eight channels of simultaneous I/O and multiple I/O formats (such
