Output busses are mapped (routed) to output paths, as configured on the Output page of the I/O Setup. Output paths are then assigned to the system’s physical audio outputs in the I/O Setups Grid (see
Assigning Paths to Hardware I/O).
When you create a new output path on the Output page of the I/O Setup, a new output bus of the same width is automatically created and mapped to that output path. Output busses are also created and mapped according to default settings when creating a new session or restoring defaults (see
Restoring Default Paths and Path Names).
