Audio output patches
An output patch is a reusable mapping from logical patch channels/buses to one or more physical audio devices and their channels. Cues target patches (or direct devices); patches own the hardware map for the show.

Concepts
| Term | Meaning |
|---|---|
| Patch | Named table of output channels and device mappings |
| Device | SDL-visible output opened for the session |
| Direct output | Cue points at a device name without going through a patch object |
Patches are part of show settings and participate in undo when you change them (AudioPatch / AudioDevices history keys). Restoring patches recreates patch objects and reopens listed devices — UI must not keep stale references.
Workflow
- Open devices you need for the venue.
- Create a patch sized for your bus count.
- Assign each patch output cell to device channels.
- Point audio (and video-embedded audio) components at the patch.
- Save the show so the map travels with the
.c2.
