Chapter 2: Pro Tools System Conﬁgurations

There are two types of Pro Tools systems: TDM and LE. These refer to both the Pro Tools software and its associated hardware, as follows:

• TDM = Pro Tools TDM software for Pro Tools|HD-series and Pro Tools|24 MIX-series hardware.

• LE = Pro Tools LE software for Digi 002, Digi 002 Rack, Digi 001, or Mbox hardware.

Pro Tools TDM Systems

Pro Tools TDM systems are available in the conﬁgurations shown below. Each system requires at least one Digidesign audio interface (sold separately). TDM systems can be expanded by adding Digidesign cards to increase track count, add to the amount of possible plug-in and mixer processing, and connect additional audio interfaces.

Pro Tools system performance depends on factors such as computer processor speed, amount of system memory, and hard drive performance. Contact your Digidesign dealer or visit Digidesign’s Web site for the latest system requirements and compatibility information.

Pro Tools Reference Guide6

TDM System Playback, Recording and Voice Limits

The following table lists the audio playback, recording, and voiceable track limits of each type of Pro Tools TDM system. Playback and recording voices refer to the number of unique simultaneous playback and record tracks on your system. Total voiceable tracks refers to the maximum number of audio tracks that can share the available voices on your system. (Mono tracks take up one voice. Stereo and multichannel tracks take up one voice per channel.) Voice limits are dependent on the session sample rate and the number of DSP chips dedicated to the system’s Playback Engine. Pro Tools HD-series systems can open sessions with up to 256 audio tracks (and Pro Tools|24 MIX-series can open sessions with up to 128 audio tracks), but any audio tracks beyond that system’s voiceable track limit will be automatically set to Voice Off.

Pro Tools|HD-series systems provide up to 128 Auxiliary tracks (Auxiliary Inputs); Pro Tools|24 MIXseries systems provide up to 64 Auxiliary Inputs. All TDM-equipped Pro Tools systems also provide a total of 64 internal mix busses, and up to 5 inserts and 5 sends per track (depending on the DSP capacity of your system). In addition, Pro Tools TDM systems support up to 256 MIDI tracks.

Pro Tools LE System Capabilities

Table 5 lists the playback, recording, and input and output capabilities of each Pro Tools LE system. All Pro Tools LE systems support up to 32 or 24 audio tracks, as noted in Table 5. (Mono tracks take up a single audio track, while stereo tracks take up two tracks.) If you open a Pro Tools session created on a TDM system containing more than the number of tracks supported on the LE-based system, audio tracks beyond the LE system’s voiceable track limit will be automatically set to inactive (Pro Tools

6.x), or will not open (Pro Tools 5.3.3 or lower). Additionally, with 5.3.3 or lower, if you save the session, the tracks beyond the voiceable track limit will be deleted from the session data.

All Pro Tools LE series systems provide up to 128 Auxiliary tracks (Auxiliary Inputs), a total of 16 internal mix busses, and up to 5 inserts and 5 sends per track (depending on your computer’s processing capacity). In addition, Pro Tools LE systems support up to 256 MIDI tracks (Pro Tools 6.x).

Chapter 3: Pro Tools Concepts

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

Hard Disk Audio Recording

The Digidesign Audio Engine

DAE (or Digidesign Audio Engine) is Digidesign’s real-time operating system for digital recording systems. When you install Pro Tools, DAE is automatically installed on your system.

Tape-based recording is a linear medium—you need to rewind or fast forward a tape to hear a particular spot in a recording. To rearrange or repeat material in a linear system, you need to rerecord it.

Hard disk recording is a nonlinear (or random access) medium—you can go immediately to any spot in a recording without having to rewind or fast forward.

Nonlinear systems have several advantages. You can easily rearrange or repeat parts of a recording by making the hard disk read parts of the recording in a different order and/or multiple times. In addition, this re-arrangement is non- destructive, meaning that the original recorded material is not altered.

Pro Tools is a nonlinear recording system that lets you rearrange and mix recorded material nondestructively.

In the same way that a computer’s operating system provides the foundation for programs that run on the computer, DAE provides the foundation for much of the hard disk recording, digital signal processing, mix automation, and MIDI functionality required by Pro Tools and other products from Digidesign and its Development Partners.

The DAE Playback Buffer Size determines the amount of memory allocated within DAE to manage disk buffers, which affects system performance. For more information, see “DAE Playback Buffer Size” on page 40. The DAE Playback Buffer Size can be changed in the Playback Engine dialog, discussed below.

Chapter 3: Pro Tools Concepts 11

Playback Engine Dialog

Pro Tools takes advantage of your computer’s host processor for certain tasks and optional host-based DSP processing.

Pro Tools LE uses host (CPU) processing to provide audio track recording, playback, mixing, and effects processing. Pro Tools TDM can also use host processing to run RTAS plug-ins for effects processing. Performance is determined by your system and its Playback Engine settings.

Pro Tools Sessions

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

Session File

The Playback Engine dialog lets you set a hardware buffer size and allocate a percentage of CPU resources for these tasks. For more information, see “Configuring Pro Tools System Settings (in the Playback System Engine)” on page 37.

Playback Engine dialog for Pro Tools TDM system

From the Playback Engine dialog, you can also select the number of voices and voiceable tracks for your system and its sessions. Voice count choices in the dialog are based on how much DSP processing you want to allocate for voicing. For more information, see “Conﬁguring Pro Tools System Settings (in the Playback System Engine)” on page 37.

See also “System Resources” on page 16.

Pro Tools session ﬁle icon, Pro Tools 6.x

A session ﬁle is the document that Pro Tools cre- ates when you start a new project. The session file contains maps of all elements associated with a project, including audio files, MIDI data, and all your edit and mix information. You can make changes to a session and save those changes in a new session file. This lets you create multiple versions of a project or back up your editing and mixing work.

Audio File

When you record audio into a Pro Tools session, audio files are created.

Audio ﬁle icon, Pro Tools 6.x

Audio files for each session are stored in a folder named “Audio Files.” Audio files are listed in Pro Tools’ Audio Regions List and can appear in a track. A section of an audio file can be defined as a region. See “Regions (or Loops)” on page 13.

The Playback Engine dialog is also where you dedicate DSP resources for Delay Compensation.

Pro Tools Reference Guide12

Tracks

Pro Tools tracks are where audio, MIDI, and automation data are recorded and edited.

Audio tracks in the Edit window

MIDI track in the Edit window

Audio and MIDI tracks can be edited into regions or repeated in different locations, to create loops, re-arrange sections or entire songs, or to assemble tracks using material from multiple takes.

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

Regions (or Loops)

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

Playlist

Playlist Selector pop-up menu

A playlist is a group of regions arranged on an audio or MIDI track. Tracks have edit playlists and automation playlists.

On audio tracks, an edit playlist tells the hard disk which audio files to read in what order. For example, you can use the same audio region to access the same piece of audio multiple times at different locations and not use additional disk space. Different versions of the same original audio can be used in different places and have different effects applied.

A playlist can be made up of a single region or many separate regions. It can be made up of similar elements, such as regions from several different takes of a solo, or dissimilar elements, such as several sound effects. You can create any number of edit playlists for a track. This lets you assemble different versions of performances or edits on a single audio or MIDI track and choose between them with a pop-up menu on the track.

Audio region

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

Channel

The term channel is used to describe several related components of a Pro Tools system. The first example of channel refers to a physical input or output of your Pro Tools system.

For example, a 96 I/O audio interface (Figure 1) provides up to 16 channels of input and output to a Pro Tools|HD system. An 888|24 I/O audio interface provides eight channels of analog input and output to a Pro Tools TDM system.

The second use of the term channel refers to a mixer strip in the Pro Tools Mix window. The term channel strip refers to the mixer strip of any track (audio or MIDI track, Auxiliary Input, or Master Fader) in a session.

Audio and MIDI channel strips have similar controls, but those controls have slightly different effects. For example, audio and Auxiliary Input channel strip faders control the output gain to the mix bus for that channel, while MIDI channel strip faders send MIDI volume data (MIDI controller 7) to the MIDI instrument.

Figure 2. Channel strip in the Mix window

The term channel also describes a separate aspect of MIDI operation. See “MIDI Concepts” on page 19.

Pro Tools Reference Guide14

Signal Routing

Pro Tools provides software-based mixing and signal routing controls. The Mix window is where these controls are located. (Some of these controls can also be accessed from the Edit window.)

Inserts

Sends

Stereo plug-in

Signal Routing Example

A common signal routing task is to submix multiple tracks to a single channel strip (such as an Auxiliary Input or a Master Fader) for shared processing and level control. The following example shows three audio tracks submixed to a stereo Auxiliary Input.

Input from Stereo

Outputs to Stereo Bus path

Audio Tracks

Bus path

Output to Stereo Output path

Auxiliary Input

Submixing to an 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 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.

Chapter 3: Pro Tools Concepts 15

Auxiliary Inputs and Master Faders Auxiliary Inputs are tracks that can be used as returns, submixers and bus masters. Master Faders are used as bus and output master level controls. Both Auxiliary Inputs and Master Faders can have plug-in and/or hardware inserts.

Sends Sends route audio to internal busses to send to other tracks in Pro Tools, or to hardware outputs. Master Faders do not have sends.

Plug-In and Hardware Inserts Software plug-ins and hardware inserts process the audio on their associated track. Plug-in processing occurs completely within the Pro Tools system. Hardware inserts utilize audio interface inputs and outputs, for traditional insert routing to (and from) external effects and other devices.

Paths Pro Tools lets you define any internal or external input, output, bus, or insert with a single name and format (mono, stereo, or multichannel). Paths comprise the lists of available routing choices in track I/O Selectors and other menus. Paths are auto-named by default, but can be customized in the I/O Setup window. See Chapter 7, “I/O Setup” for more information.

Mixing Formats Sessions can include combinations of mono, stereo, and multichannel format tracks, busses, inputs, outputs, and inserts. (Multichannel formats are supported on Pro Tools HD-series and MIX-series systems only.)

System Resources

Track count, plug-in processing, signal path and routing options, and voice availability are ultimately limited by the combined resources available from the host computer, and from your Pro Tools hardware.

Pro Tools provides several ways to manage and conserve resources to maximize the performance of your system. As you begin working with Pro Tools sessions and tracks, you can take advantage of the following features to extend the effectiveness of your available DSP and other resources:

◆ Pro Tools lets you adjust the performance of

your system by changing system settings (such as H/W Buffer Size and CPU Usage) that affect its capacity for processing, playback, and recording. See “Conﬁguring Pro Tools System Settings (in the Playback System Engine)” on page 37.

◆ Pro Tools allows for session items (such as

tracks and inserts) to be manually made inactive, to free up DSP resources. Inactive elements are viewable, editable, and retained within the session. See “Active and Inactive Items” on page 17.

◆ All Pro Tools TDM systems, as well as LE sys-

tems (Pro Tools 6.x only), provide ﬂexible voice options for audio tracks, to help maximize use of available voices in your system. For more information on voice management and options, see “Voiceable Tracks and Track Priority” on page 98.

Pro Tools Reference Guide16

Active and Inactive Items

Pro Tools lets you set certain items (such as tracks and inserts) as inactive, in order to free up DSP resources and mixer connections.

Items in Pro Tools that can be made inactive (or active) include the following:

• Audio tracks, Auxiliary Inputs, and Master Faders

•Track Inputs and Outputs

• Sends

• Side-chain inputs

• Plug-ins

• Hardware inserts

• Paths (session-wide)

MIDI tracks cannot be made inactive.

In addition to manually setting Active and Inactive modes, Pro Tools will automatically make items inactive if there are insufficient or unavailable resources.

When active, items are fully engaged and operational.

Paths and Path Assignments When a path or path assignment is inactive, its mixer resources are made available for other signal routing purposes in the session. Paths and assignments can be made inactive manually, or automatically (see “Automatic and Manual Inactive Mode” on page 18).

Tracks For TDM systems (Pro Tools 5.1 and higher) and LE systems (Pro Tools 6.x), when a track is made inactive, its voices become available for another track. Mono inactive tracks free up one voice, and stereo and multichannel tracks free up one voice per channel. Additionally, when an audio track, Auxiliary Input, or Master Fader is made inactive, its plug-ins, inserts, sends, and I/O assignments become inactive, and the associated DSP used is freed up for use elsewhere in the session.

When 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 18).

Chapter 3: Pro Tools Concepts 17

Display of Inactive Items

Automatic and Manual Inactive Mode

When items are inactive, their names appear in italics, and their background becomes dark grey. When a track is inactive, the entire channel strip is grayed out.

Active Inactive plug-in

Inactive track

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, creating a session on a Pro Tools|24 MIX-series system, then opening it in on a Pro Tools|HD-series system).

Whenever this occurs, the session will open as it was last saved. All items that are unavailable, or cannot be loaded due to insufficient resources, are made inactive.

Manual Inactive Switching

Active and inactive items and tracks

Pro Tools Reference Guide18

You can manually apply Active or Inactive modes to manage system resources. By making an item inactive, its associated resources are made available elsewhere in the session.

The following are basic instructions for manually making items inactive. Throughout the Pro Tools Reference Guide, instructions are provided whenever an item can be made inactive.

To toggle an item active or inactive:

■ Control-Start-click (Windows) or Command-

Control-click (Macintosh) the item.
