System Configuration : I/O Setup : Creating New Paths

Creating New Paths
For more information, see the following topics:
The I/O Setup lets you create new paths with custom names, formats, and assignments to physical I/O. Custom path names appear in a session’s track Input, Output, Insert, and Bus selectors.
To create a new path:
1 Choose Setup > I/O.
2 Click the Input, Output, Insert, or Bus tab to display the corresponding path type.
3 Click New Path.
4 In the New Path dialog, specify the number of new paths you want to create, the channel width for each path, and the path name.
 
5 Do one of the following:
*   
– or – 
*   
*
Add a new path by pressing Command+N (Mac) or Control+N (Windows), or by pressing Command+Plus (+) (Mac) or Control+Plus (+) (Windows) on the numeric keypad.
*
To remove the last path from the New Path dialog Command+Minus (–) (Mac) or Control+Minus (–) (Windows).
6 Enable (or disable) the New Paths options Add the Default Channel Assignments and Auto-Create Sub-paths.
7 Click Create.
*
When you create a new Output path, an output bus is automatically created on the Bus page of the IO Setup, and is automatically mapped to the output path you created. See Output Busses.
8 Assign the path to a specific audio interface (Input, Output, and Insert pages only) in the Grid column. See Assigning Paths to Hardware I/O.
9 Repeat the previous steps to configure all path types (Input, Output, Insert, or Bus).
10 Click OK to save changes and close the I/O Setup. If there are any identically named paths, you will be instructed to correct them before the I/O Setup will close. For more information, see Valid Paths and Requirements.
