Assigning Paths to Hardware
I/O
Paths are assigned to specific inputs, outputs, and
inserts in the Grid. Paths can be assigned to physi-
cal I/O in the Grid, and can be reassigned at any
time.
To assign channels:
1 Select (or create) a main path or sub-path.
2 Select the channel Format (such as Stereo).
3 In the row for the selected path, click in the Grid
column under an audio interface and channel.
Other channels for the path type, if any, fill to the
right. For example, when assigning a new stereo
path, clicking in the path row under output channel
1 fills both channel 1 and 2 (left to 1, right to 2).
4 Click OK to save changes and close the I/O
Setup.
If there are any invalid settings, you will be re-
quired to correct them before the I/O Setup will
close. For more information, see “Valid Paths and
Requirements” on page 114.
Assigning Paths with the Surround Mixer
(Pro Tools HD and Pro Tools with Complete
Production Toolkit Only)
When assigning multichannel paths, the left chan-
nel (L) is assigned first to the clicked Grid box, and
remaining channels fill immediately to the right
according to the default path order.
Because some multichannel mixing formats use
unique track layouts, Pro Tools lets you set the de-
fault format in the I/O Setup (see “I/O Setup Op-
tions” on page 96).
Reassiging Paths
You can move the individual assignments to dif-
ferent channels, to reorder the path’s definition
(for example, changing a multichannel path to L-
R-C-LFE-Ls-Rs).
To reassign channels in a path:
 Drag the channel to the new location in the
Grid. Other channel assignments move (shuffle)
to accommodate dragged channels.
Channel Shuffling
Moving a signal from right to left results in a shuf-
fle of other signals after the new destination chan-
nel. Moving a signal from left to right shuffles any
and all signals after the new destination channel
and leaves the previous channel empty.
Assigning channels
To reassign channels in a path, see
“Reassiging Paths” on page 113.
Customized Output paths for a 5.1 mix
Changing a path’s format erases any cur-
rent channel assignment.
