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.
