thanks SB-SIX that helped. I have successfully routed the audio, but when I use the on board keyboard the pitch of track 1’s oscillators are not following the keyboard and are locked to a fixed pitch, for some reason? I can use my midi controller on Track 1 and Track 2 (to trigger its env, i presume) and that works. I have the volume on the oscillator of track 2 off to use it’s filters only.
