Surround : Pro Tools Setup for Surround : Configuring Pro Tools for Multichannel Sessions

Configuring Pro Tools for Multichannel Sessions
For more information, see the following topics:
Configuring Pro Tools and sessions for multichannel mixing can be done in any (or all) of the following ways:
New Sessions
You can create a new session and choose a surround mix I/O Settings file as the default I/O Setup. See New Sessions and I/O Settings.
Remixing Sessions in Surround (Importing Multichannel I/O Setups)
By creating or importing a surround mix I/O Settings file in the I/O Setup dialog, multichannel paths can be made available in any stereo (or other format) session. You can then reassign track routing from the original stereo paths to multichannel paths. Inactive and active paths simplify reassignment. See Importing Multichannel I/O Setups.
Custom Multichannel Paths
You can customize and redefine existing paths in the I/O Setup dialog. For more information, see Custom Multichannel Paths.
Importing Session Data
By using the Import Session Data command (File > Import > Session Data), you can import tracks and media from other sessions plus their associated paths and track assignments. After importing session data, you can use the I/O Setup dialog to configure main and sub-paths for the requirements of the session. For more information, see I/O Setup.
