I haven’t tried this yet as I am currently setting up my studio to do this. But, it seems that it should work… In theory.

Link each track to your daw via midi. One separate DAW midi channel per OT channel (auto channel turned off). Then record on each DAW midi channel while performing. You cannot record the crossfader movements with midi, but the parameters that the crossfader affects should record to the DAW midi channels. Then you can play back the recorded performance, solo-ing each track at a time and recording the audio to separate audio tracks.

The cue outputs are handy too.
