I regularly use multi-output audio interfaces. While programming I use a iConnectAudio4+, and on stage I use a X-Air 18. When I pull up my GIGs, they work when developing and when performing due to alike number of outputs.
If I work offline (just the Mac), it uses the “Built-In Output” of the Mac. This is only 2 channels. Left & Right.
I lose the channels set to 3 & 4 (stereo), 5 (mono), 6 (mono), 7 & 8 (stereo), etc…
I know I can reroute these, but then when I perform live, I have to reroute them all again. Hopefully I remembered and did it correctly.
Is there a way, on a Mac, to have multiple virtual outs that mix to L & R of the “Built-In Output” where I don’t need to disturb my audio application output assignments?
