Say I have a multitimbal vsti like sampletank or kontakt on a track 1. In it, I load 3 instruments, assigned to MIDI ch 1,2,3, each routed to corresponding output channels. How do I make track 2 map to track 1’s MIDI ch 2, and track 3 map to MIDI ch 3? And how do I deal with the audio routing? Ideally, track 1 will get the audio output of kontakt’s out 1, track 2 gets kontakt’s out 2, and so on, so I can mix them separately.
