Hey there! Sorry for the late reply and not seeing the question in the Discord either..
But hey, welcome to Backstage! 
Without further ado, here’s the tea 
:
Anything you play in Performance mode will be reflected in the individual USB audio channels that are affected by it. So yes, you can record the performance and then work with the individual tracks/channels afterwards.
One thing to note. Performance Mode still affects only the steps of the first 8 channels, so you’ll have to plan your tracks accordingly. There are some exceptions though, since there are Synth Engine specific performance effects. They don’t care which channel you put them on. Unless you want to affect their steps.
Hope that helps. If you got any other questions, let me know!
