To be honest, I think this is a fools errand. There are MANY devices with large numbers of channels. The way these devices are connected to speakers is not defined anywhere. You can also forget jack-sensing and stuff like that. Even sitting right next to me is a fireface 400, with 18 channels of output. You have no idea how this is wired up in my office/studio, and there's nothing you can do to find out except ... ask me. the "output modes" in audio/MIDI setup have essentially nothing to do with this. _______________________________________________ Do not post admin requests to the list.
