Im trying to configure a Soundcraft MTR 12 to send each audio track to its own output channel. The mixer is12 channels (plus 2 masters as 13 and 14). I can separate the analogue inputs as 1 through 12 for recording but not the outputs. The Soundcraft AISO driver (3.20) does support this. Anyone use more than a 2 channel USB audio device and separate the channels?
