I can't figure out how to send my custom Aux Mix 3/4 out of the firewire into my Mac, so that I can insert that into OBS. My board is connected to the Mac, and I can see all 24 channels in Capture 3, I just don;t know what "mix" Capture is seeing. It appears to be the main mix. Can I make that an Aux mix? I've looked around UC for hours in the AUX routing area, but can't figure out how to accomplish this. Thanks for your help.
