Chapter 2: Pro Tools Concepts

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

Hard Disk Audio Recording

Hard disk recording is a nonlinear (or random ac- cess) 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 a tape to hear a particular spot in a recording. To rearrange or repeat material in a linear system, you need to re-record it, or cut and splice it.

Nonlinear systems have several advantages. You can easily rearrange or repeat parts of a recording by making the hard disk read parts of the recording in a different order and/or multiple times. In addition, this re-arrangement is non- destructive, 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 like you would with tape.

Chapter 2: Pro Tools Concepts 5

The Digidesign Audio Engine

The Digidesign Audio Engine (DAE) is Digidesign’s 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 Digidesign 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 dialog.

For information on configuring the DAE Playback Buffer Size, see “DAE Playback Buffer Size” on page 40.

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

The Playback Engine dialog lets you set a hardware buffer size and allocate a percentage of CPU resources for these tasks.

Playback Engine Dialog

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 dialog (Setup > Playback Engine).

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

Pro Tools Reference Guide6

Playback Engine dialog for Pro Tools|HD system

On Pro Tools|HD systems, you can select the number of voices and voiceable tracks for your system and its sessions. Voice count choices are based on how much DSP processing you want to allocate for voicing.

On Pro Tools|HD systems, the Playback Engine dialog is also where you assign dedicated DSP resources for Delay Compensation.

For more information, see “Configuring Pro Tools System Settings” on page 34. See also “System Resources” on page 16.

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.

passes input

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 A hardware MIDI device or software instrument (such as an instrument plugin).

MIDI Interface Hardware that lets computers connect to and communicate with MIDI devices.

MIDI Device Any physical MIDI keyboard, sound module, effects device, or other equipment that can send or receive MIDI information.

MIDI Controller Any MIDI device that transmits MIDI performance data. These include MIDI keyboards, MIDI guitar controllers, MIDI wind controllers, and others. Controllers transmit MIDI from their MIDI OUT ports.

MIDI signal ﬂow

Not all devices will have all three MIDI ports (IN, OUT, and THRU).

The MIDI protocol provides 16 channels of MIDI per port. A single MIDI cable can transmit a separate set of messages for each of the 16 channels. These 16 channels can correspond to separate MIDI devices or to multiple channels within a single device (if the device is multi- timbral). Each channel can control a different

MIDI Control Surface Any device (such as the Digidesign Command|8), which uses a MIDI connection to send control messages to a software program, but is not generally used to record MIDI information.

Multitimbral The ability of one MIDI device to play several different instrument sounds (such as piano, bass, and drums) simultaneously on separate MIDI channels. This makes it possible for a single multitimbral MIDI instrument to play back entire arrangements.

Chapter 2: Pro Tools Concepts 7

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 (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 right ones.

Program Change Event A MIDI command that tells a sound source which of its sounds (or sound patches) to use. The MIDI protocol lets you choose from a range of 128 patches.

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. 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 MIDI Misconceptions

MIDI is not audio, and by itself makes no sound. MIDI is control information only. It is like the piano roll for a player piano; it provides control information for what note to play when, for how long, at what volume, and 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 2) or some other MIDI interface (such as a Digidesign MIDI I/O).

Pro Tools Reference Guide8

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. Consult the device’s documentation for information on its capabilities.

outputs time code or MIDI Beat Clock and another device synchronizes to or follows that time code or MIDI Beat Clock so that they work together according to the same clock source. Pro Tools can be synchronized to other devices (or other devices can be synchronized to Pro Tools) using SMPTE/EBU time code or MIDI Time Code.

For more information on different SMPTE/EBU formats, and other concepts related to time code, refer to the Pro Tools Sync & Surround Concepts Guide.

Surround

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.

MIDI In Pro Tools

Pro Tools provides MIDI sequencing capabilities. You can record, enter, edit, and playback MIDI data on Pro Tools tracks and in 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 Digidesign MIDI I/O or Mbox 2) 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

There are multiple types of surround formats in use (from three-channel LCR to 7.1, which has 8 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.

Only Pro Tools HD supports mixing in surround formats. In Pro Tools, each surround format is considered to be a Pro Tools greater-than-stereo multichannel format.

For information on fundamental surround concepts, see the Pro Tools Sync & Surround Concepts Guide.

Chapter 2: Pro Tools Concepts 9

Pro Tools Sessions

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

Session File

A session ﬁle is the document that Pro Tools cre- ates when you choose File > New Session and configure a new session. Pro Tools can open only one session file at a time. The session file is named with a .ptf (Pro Tools file) extension. Session files contain maps of all elements associated with a project, including audio files, MIDI data, and all your edit and mix information. It is important to realize that a Pro Tools session file does not contain any media files (audio or video). Instead, it references audio, video, MIDI, and other files. You can make changes to a session and save those changes in a new session file. This lets you create multiple versions of a session or back up your editing and mixing work.

Although there are different session file icons, the session files may be opened by the other types of Pro Tools system software (with certain restrictions). See “Opening a Session” on page 97.

When a session is transferred to a different Pro Tools system, its session file icon changes to the icon type of the destination system.

Tracks

Pro Tools tracks are where audio, MIDI, video, and automation data are recorded and edited. Pro Tools tracks also provide audio channels for routing internal busses, and physical inputs and outputs for audio and MIDI.

Pro Tools provides mulitple types of tracks: audio, Auxiliary Input, Master Fader, VCA Master, MIDI, Instrument, and video.

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

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 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 Vista only). Additionally, Avid video is supported on Pro Tools LE or Pro Tools HD with an Avid video peripheral, or Pro Tools LE with DV Toolkit 2 software. An individual video track can play back only one type of video at a time.

Audio, Auxiliary Input, Master Fader, VCA Master (Pro Tools HD only), and Instrument tracks can be mono, stereo, or multichannel (Pro Tools HD only). When creating a new track, select from the list of channel formats supported by your system.

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

Audio files for each session are stored in a folder named “Audio Files.” Audio files are listed in the Pro Tools Region List and can appear in an audio track. A section of an audio file can be defined as a region. See “Regions” on page 12.

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.

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.

Chapter 2: Pro Tools Concepts 11

Regions

Audio region

MIDI region

Video region (Frames View)

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 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

Playlist selector pop-up menu

Region group (Mixed audio and MIDI multitrack region group)

Pro Tools Reference Guide12

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

On audio tracks, an edit playlist tells the hard disk which audio regions to play in what order. For example, you can have separate audio regions for a song introduction, the first verse, the first chorus, and so on. You can also use the same audio region to access the same piece of audio multiple times at different locations and not use additional disk space. Different versions of the same original audio can be used in different places and have different effects applied. On MIDI and Instrument tracks, edit playlists can store multiple MIDI sequences (or performances) on a track.

A playlist can be made up of a single region or many separate regions. It can be made up of similar elements, such as regions from several different takes of a solo, or dissimilar elements, such as several sound effects.

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 a popup menu on the track.

Each track also 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 provides up to 16 channels of input and output to a Pro Tools|HD system, while an Mbox 2 audio interface provides up to four inputs and two outputs.

The second use of the term channel refers to a channel strip in the Pro Tools Mix window. Each track in a Pro Tools session has a corresponding channel strip in the Mix window.

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

Channel strip in the Mix window (audio track)

The term MIDI channel also describes a separate aspect of MIDI operation. See “MIDI” on page 7.

Chapter 2: Pro Tools Concepts 13

Signal Routing

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 three 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 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 route audio inputs to other busses, sends, or outputs, as well as to send MIDI to external 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. Master Fader and VCA Master tracks do not have sends.

Plug-in and Hardware Inserts Plug-in processing occurs completely within the Pro Tools system. Hardware inserts use audio interface inputs and outputs, for traditional insert routing to and from external effects and other devices.
