Chapter 13: Tracks 247
For stereo and multichannel surround tracks, in-
puts and outputs appear as stereo pairs and multi-
channel groups. The available inputs, outputs, and
busses are defined as paths in the I/O Setup dialog
(see Chapter 6, “I/O Setup”).
Automatic Input and Output
Assignments
When adding tracks to a new session, inputs are
automatically assigned in ascending order. For ex-
ample, if you have an audio interface with eight in-
puts, creating four new mono audio tracks will au-
tomatically add four audio tracks with inputs
assigned to the first four paths defined in the I/O
Setup dialog. When creating stereo tracks, inputs
are automatically assigned to subsequent input
pairs.
The outputs automatically assigned to new tracks
are determined by the
New Track Default Output
Bus
specified in the I/O Setup dialog.
Assigning Audio Inputs
(Audio, Auxiliary Input, and Instrument Tracks)
To assign an audio input of an audio, Auxiliary
Input, or Instrument track:
1 In order to assign audio track inputs in the Edit
window, select
View > Edit Window > I/O.
2 In the Mix or Edit window, click the track’s In-
put Path selector and choose from the available
audio interface channels and busses. Stereo and
multichannel surround tracks have inputs avail-
able as pairs and multichannel groups.
The Input Path selector lets you route any audio in-
put or any of the Pro Tools internal busses to an au-
dio, Auxiliary Input, or Instrument track. The
choices available in this pop-up menu are deter-
mined by the Input Path configuration in the I/O
Setup. Inputs in use by another track appear bold in
the Input Path selector pop-up menu.
To automatically assign all track inputs (of the
same type and channel width) to unique ascending
Input paths (cascading):
 Command-Option-click (Mac) or Control-Alt-
click (Windows) the Input Path selector of the
left-most Input Path selector and select the first
Input Path (mono or stereo, depending on
whether your tracks are mono or stereo).
All visible tracks of the same channel width (mono
or stereo) are auto-assigned to unique Input Path
assignments in ascending order. For example,
Track 1 to A1, Track 2 to A2, Track 3 to A3, and so
on.
To remove an input assignment:
 Select No Input from the Input Path selector.
Instrument tracks automatically assign the
audio output from the instrument plug-in in-
serted on the track to the track audio Input.
