Although there are different session file icons,
the session files may be opened by all three ap-
plications (with certain restrictions). See “Open-
ing a Session” on page 85.
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 seven types of tracks: audio,
Auxiliary Input, Master Fader, VCA Master,
MIDI, Instrument, and video.
Audio, MIDI, and Instrument track data can be
edited into regions or repeated in different loca-
tions to create loops, re-arrange sections or en-
tire 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 both QuickTime movies
and Avid video, but an individual video track
can play back only one of these types of video at
a time.
Audio, Auxiliary Input, Master Fader, VCA Mas-
ter (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.
Audio File
When you record audio into a Pro Tools session,
audio files are created.
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 au-
dio track. A section of an audio file can be de-
fined as a region. See “Regions” on page 8.
When a session is transferred to a different
Pro Tools system, its session file icon
changes to the icon type of the destination
system.
