Hi there @xbrett82
To my understanding the reason why CS is recording the instrument again on a new track is because he's layering several instances with different effects processing on each tracks. Just bouncing the track to audio would require to disable all the unwanted effects before, so it's more a workflow thing IMO.
You can't just bounce audio directly inside Live like you can do inside Logic, you either need to freeze the track first and then flatten the track to audio, or route the track out to a new audio track in and record the midi output. Doing it with tracks I/O allows you to keep or bypass your effects, but in the end it's much more cumbersome to work this way than just recording a new part on a new track.
