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.
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.
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 9
DAE
DAE, the Pro Tools audio engine, is a real-time
operating system for digital audio recording,
playback, and processing. When you install
Pro Tools, DAE is automatically installed on
your system.
In the same way that a computer’s operating system provides the foundation for programs that
run on the computer, DAE provides the foundation for much of the hard disk recording, digital
signal processing, and mix automation required
by Pro Tools and other products from Avid and
its Development Partners.
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 (
Pro Tools takes advantage of your computer’s
host processor for certain tasks and optional
host-based plug-in 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-based processing to run Native
AAX (Avid Audio Extension) and RTAS
Time AudioSuite) plug-ins for effects processing. Performance is determined by your system
and its Playback Engine settings.
Setup > Playback Engine).
®
(Real-
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.
For more information, see “Configuring
Pro Tools System Settings” on page 62. See
also “System Resources” on page 21.
Pro Tools Reference Guide10
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.
MIDI signal flow
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.
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.
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.
MIDI Terms
The following are some basic MIDI terms:
MIDI Instrument
software instrument (such as an instrument
plug-in).
MIDI Interface
connect to and communicate with MIDI devices
(such as the M-Audio MIDISPORT).
MIDI Device
module, effects device, or other equipment that
can send or receive MIDI information.
A hardware MIDI device or
Hardware that lets computers
Any physical MIDI keyboard, sound
Chapter 2: Pro Tools Concepts 11
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.
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
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 Misconceptions About
MIDI
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.
Pro Tools Reference Guide12
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 Pro) or some other MIDI interface
(such as an M-Audio MIDISPORT).
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.
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
(such as the M-Audio MIDISPORT or Mbox Pro)
and other MIDI software (such as instrument
plug-ins and ReWire client applications).
Synchronization
When you are working with multiple time-based
systems, such as Pro Tools and an external deck,
you want both systems to be synchronized. Synchronization is where one system outputs clock
source (such as timecode or MIDI Beat Clock)
and another device synchronizes to or follows
that clock source so that they work together.
Pro Tools can be synchronized to other devices
(or other devices can be synchronized to
Pro Tools) using SMPTE/EBU timecode or MIDI
Timecode.
For more information on different
SMPTE/EBU formats, and other concepts
related to timecode, see the Pro Tools Sync
& Surround Concepts Guide.
Chapter 2: Pro Tools Concepts 13
Surround Sound
Pro Tools Sessions
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
sub-woofer on the side.
Pro Tools HD and Pro Tools with Complete Production Toolkit support mixing in surround formats. In Pro Tools, each surround format is considered to be a greater-than-stereo multichannel
format.
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 cre-
ates when you choose
configure a new session. Pro Tools can open
only one session file at a time. The session file is
named with a .ptx (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.
File > New Session and
For information on fundamental surround
concepts, see the Pro Tools Sync & Surround
Concepts Guide.

Session file icon
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 provides multiple types of tracks:
audio, Auxiliary Input, Master Fader, VCA Master, MIDI, Instrument, video, and click.
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 only) provide
control of tracks in a Mix Group that has been
assigned to the VCA Master.
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 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 clips 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.
Audio, Auxiliary Input, Master Fader, and Instrument tracks can be mono, stereo, or multichannel (Pro Tools HD and Pro Tools with
Complete Production Toolkit only). When creating a new track, select from the list of channel
formats supported by your system.
Pro Tools also lets you create a Click track so
you can record while listening to a click. Click
tracks can use the TL Metro plug-in (included
with Pro Tools) or a MIDI instrument.
Voices
In Pro Tools, voices are unique, discrete audio
streams that can be routed to and from
Pro Tools audio tracks, and 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.
Chapter 2: Pro Tools Concepts 15
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 Avid HDX and
Pro Tools|HD systems, more than one voice may
be necessary for a single channel (such as when
using host processing on a DSP or TDM bus).
Voices can be allocated dynamically (with all
Pro Tools systems, any available voices are automatically assigned as they are needed) or ex-plicitly (with Pro Tools|HD systems only, you
can explicitly assign audio channels to specific
available voices to ensure that audio on those
channels is always voiced).
On Avid HDX and 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 49).
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 Capabilities with Different
Hardware Configurations” on page 43).
Audio Files
When you record audio into a Pro Tools session,
audio files are created.
Audio file icon
Audio files for each session are stored in a folder
named “Audio Files.” Audio files are listed in
the Pro Tools Clip List and can appear in an audio track. A section of an audio file can be defined as a clip. See “Clip” on page 17.
MIDI 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.
For more information about voicing in
Pro Tools, see “Track Priority and Voice
Assignment” on page 245.
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.
Pro Tools Reference Guide16
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
.
Clip
Playlist
A clip is a segment of audio, MIDI, or video data.
A clip 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. Clips are especially useful for arranging audio and MIDI. A
clip can also have associated automation data.
In Pro Tools, clips are created from audio files
or MIDI data, and can be arranged in audio and
MIDI track playlists. Clips can also be grouped
(a “clip of clips”) and looped (repeated).
Audio clip
MIDI clip
A playlist is a sequence of clips 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 clips to play in what order. For
example, you can have separate audio clips for a
song introduction, the first verse, the first chorus, and so on. You can also use the same audio
clip 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.
Video clip (Frames view)
Clip group (Mixed audio and MIDI multitrack clip
group)
A playlist can be made up of a single clip or
many separate clips. It can be made up of similar
elements (such as clips 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 an Avid HDX,
Pro Tools|HD, or HD Native system, while the
Mbox Pro audio interface provides up to eight
inputs and eight 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.

Signal Routing Options
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.
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.
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 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 only) control
the relative mix settings for all tracks within the
selected group.
Tick-Based and SampleBased 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 clip 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 clip 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 clips in the
track have an absolute location on the Timeline.
Clips 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 clips 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 clip in a
tick-based track. If Elastic Audio is enabled on
an audio track, tempo changes apply Elastic Audio processing, which changes the duration of
the audio clip.
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 clip-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 248.
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 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:
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.
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 plug-inInactive 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 Pro 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
AA F, 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.
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.
For more information about DigiBase, see
“DigiBase” on page 285.
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, external clip names, the name of the
videotape from which the media file was
captured, and even timecode 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 OMF or MXF media files, or have OMF
and MXF 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
Pro Tools and Avid Terminology
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.
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 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.
Whole audio files in the Clip 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 clips) in the Pro Tools Clip List even
though they are audio files.
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.

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 fi le contai ning 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.

Using the Contents and Index
Tabs
The left pane of the Help browser is the display
area for most of the Help system’s main navigation tools, including the Contents and Index
tabs.
Contents Tab
When you move to a new topic, the contents expands to the level of that topic and highlights
the topic. This feature, like the hierarchy links
at the top of each topic, lets you see exactly
where the current topic is positioned within the
logical organization of the Help system.
To display a topic from the contents:
Click the Contents tab, and then click a topic’s
entry in the contents.
To expand or close a section in the contents:
Click the Contents tab, and then click a book
icon to the left of a link.
Index 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.
To find topics by using the Index tab:
1 Click the Index tab.
2 Click the first character of the topic in the
Numerics, Letters, Symbols list.
The Contents tab displays a complete hierarchical list of all topics in the Help system. This lets
you quickly see the overall organization of the
Help system.
You can expand and collapse the contents to
view the logical organization of the Help system,
and you can move to any topic by clicking its entry in the Contents.
Pro Tools Reference Guide36
To view the topic associated with an index entry:
Click the index entry.
Using the Search Tab
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 list
of results is ranked, placing the topics that the
Search feature considers most likely to be relevant at the top of the list.
When you search for text, the text string automatically highlights by default. You can turn
these highlights off. You can also stop displaying highlights after a search by using the Back
and Forward buttons to go to a different topic.
When you come back to your searched topic, the
highlights no longer display.
For more guidelines on using the Search feature
effectively, see “Search Guidelines” on page 38.
To perform a basic search:
1 Click the Search tab.
2 In the Search pop-up menu (located below the
Search text box), click whether you want to
search in “All Available Books” or a specific book
(such as Pro Tools Shortcuts).
3 In the Search text box, type the word or words
that you want to find.
4 Click Go.
A list of topics and ranking numbers appears.
Additional Search Information
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.
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, such as Mozilla
Firefox, do not have this limitation.
Chapter 4: Using Help 37
Search Guidelines
Printing Help Topics
Use the following rules for formulating search
queries:
• Searches are not case-sensitive, so you can
type your search in uppercase or lowercase
characters.
• You can search for any combination of letters
(a-z) and numbers (0-9).
• Punctuation marks (such as the period, colon,
semicolon, comma, and hyphen) are ignored
during a search, unless they are part of the
topic (such as .WAV).
• You can search for a literal phrase by using
quotation marks. You cannot search for quotation marks.
Copying from a Help Topic
You can copy information from a Help topic for
use in another document (such a text file).
To copy information from a Help topic to another
document:
1 Open or click the topic to make it active.
2 Select the text that you want to copy.
3 Choose Edit > Copy.
You can print Help topics if you need to refer to
them during a complicated procedure or to use
for reference later.
See your browser documentation for more
information on print options.
To print a Help topic:
1 Click the topic pane within the browser
window that you want to print.
2 Do one of the following:
• Click the Print button in the Topic pane.

Current Engine
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 use-
ful 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

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 Avid HDX, Pro Tools|HD, and
HD Native systems, use the default setting
HDX, HD TDM, or HD Native.
of
• For supported Pro Tools and M-Audio
audio interfaces (such as the Mbox Pro or

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
Aggregate I/O
for simultaneous input and
Pro Tools
output with the built-in I/O hardware
options.
3 Click OK.
When changing engines with a Pro Tools session
open, Pro Tools must close and relaunch the session to initialize the new engine.
Chapter 6: System Setup 63
On Avid HDX and 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
(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 us-
ing 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)
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 host-based, or “Native” plug-ins
(AAX and RTAS).
• 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 MIDI-to-audio latency (such as when
playing a 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 Avid HDX and Pro Tools|HD systems,
lower settings reduce monitoring latency
that occurs on tracks that have one or more
Native 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 Native
plug-ins 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.
Pro Tools Reference Guide64
To change the Hardware Buffer Size:
1 Choose Setup > Playback Engine.
2 From the H/W Buffer Si ze 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 Native (AAX and
RTAS) plug-in processing and other host processing tasks.
• Depending on the importance of video and
overall screen response, and on the density of
automation being employed, try different
combinations of
Usage Limit
Host Processors and CPU
settings to achieve the best results. For example, to improve screen response
in a medium-sized session using a moderate
number of Native plug-ins, try reducing the
number of Native plug-ins, but keep the
Usage Limit
set to the maximum (up to 99% on
CPU
a single processor system).
To set the number of Host Processors:
1 Choose Setup > Playback Engine.
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
Host Processors setting lets you control the
the
CPU Usage Limit setting,
way host-processing tasks are handled by the
system.
For example:
• For sessions with large numbers of Native
plug-ins, you can allocate 2 or more processors to Native processing and set a high
Usage Limit
.
CPU
• For sessions with few Native plug-ins, you can
allocate fewer processors to host-based 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 DSP
to Native plug-in conversion. Conversely, decrease these settings if you are only using DSP
plug-ins or are converting Native plug-ins to
DSP. DSP/Native conversion can be desirable
during recording, depending on latency, voicing needs, and record-monitoring capabilities
of the specific DSP and Native plug-ins.
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
1 Processor to limit host processing
for Pro Tools to one CPU in the system.
•Choose
2 Processors to enable load balanc-
ing 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 num-
Host Processors and adjust the CPU
ber of
Usage Limit
setting. (For more information, see
“System Usage” on page 83.)
Chapter 6: System Setup 65
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
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 CPUintensive 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
pends 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
ing
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.

When enabled, 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 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.
This option is only available if the

Number of Voices
(Avid HDX and Pro Tools|HD Systems Only)
On Avid HDX and 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 Avid HDX or Pro Tools|HD cards in
your system, there are different choices for
voice count. For voice limits on different Avid
HDX and Pro Tools|HD systems, see “Playback,
Recording, and Voice Limits with Pro Tools
HD” on page 49.
Chapter 6: System Setup 67
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 Avid HDX or 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 Avid HDX or
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
Avi d HDX or 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.
Sample Rate (Playback Engine)
(Avid HDX and Pro Tools|HD Systems 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. (

Delay Compensation Engine
Delay Compensation Settings
Depending on your Pro Tools system, the Delay
Compensation Engine
setting in the Playback Engine determines how much DSP or host-based
processing 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 enable or disable Delay Compensation (

To configure the Delay Compensation Engine:
1 Choose Setup > Playback Engine.
2 From the Delay Compensation Engine pop-up
menu, select
3 Click OK.
None, Short, Long, or Maximum.
Depending on your Pro Tools system, there are
up to four settings available in the Playback Engine to dedicate processing resources for Delay
Compensation:
None
Allocates no resources for Delay Compen-
sation.
Short
Provides 1,023 samples at 44.1/48 kHz,
2,047 samples at 88.2/96 kHz, or 4,094 samples
at 176.4/192 kHz 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 DSP and host–based delay, this
setting should be sufficient.
Long
Allocates 4,095 samples at 44.1/48 kHz,
8,191 samples at 88.2/96 kHz, or 16,382 samples
at 176.4/192 kHz of 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.
Maximum
Allocates 16,383 samples at
44.1/48 kHz, 32,767 samples at 88.2/96 kHz, or
65,534 samples at 176.4/192 kHz of Delay Compensation for each mixer channel. For sessions
with plug-ins on mixer channels that result in
more the 4,000 samples of delay at 48 kHz, select
this setting.
The Maximum option is unavailable with
Pro Tools|HD systems.
Pro Tools HD with Avid HDX hardware
acceleration always uses the full DSP
resources of the Maximum setting when
Delay Compensation is enabled. The None,
Short, and Long settings are included only
for compatibility with legacy sessions.
Chapter 6: System Setup 69
System Memory Allocation
(Pro Tools|HD Systems Only)
When you start your computer, Pro Tools automatically reserves a portion of system memory
for the 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.
Cache Size
(Pro Tools HD and Pro T ools with Complete
Production Toolkit Only)
The Cache Size setting in the Playback Engine
determines the amount of memory DAE allocates to pre-buffer audio for playback and recording. In most cases, the default setting of
Normal is the optimum Cache Size for most ses-
sions.
Pro Tools HD and Pro Tools with Complete Production Toolkit can also load audio files used in
Pro Tools sessions into RAM for cached playback. Pro Tools prioritizes files closest to the
current playhead location. This way, when you
start playback, those files are already cached for
playback. This is especially useful when working
with shared media storage (such as with Avid
Unity MediaNetwork and ISIS shared storage
systems).
To determine the maximum amount of RAM
available for Disk Cache, Pro Tools polls the
computer for the amount of RAM installed and
subtracts 3 GB with Mac systems or 4 GB with
Windows systems.
For example, if your computer has 12 GB of
RAM installed, the total amount of RAM available for the Disk Cache will be 9 GB (Mac) or 8
GB (Windows).
Note that Windows systems reserve more RAM
for the system than Mac systems.
You can use the Cache Meters in the System
Usage window to determine whether or not
to assign more or less RAM to the Disk Cache
for the current session. See “Cache Meters”
on page 83.
To set the amount of RAM for use by the Disk
Cache:
1 Choose Setup > Playback Engine.
2 From the Disk Cache selector, select the
amount of RAM you want to allocate for Disk
Cache.
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
Streaming Buffer Size
