My apologies if I missed a thread with this information, but I have been struggling to find info on this online, Here's my scenario:

When I play live, I use majority of my sounds from the MODX itself, however there is some performances that I need to midi-out to my DAW for a VST to be layered over my onboard sounds. I have created an individual performance for my VST -> enabled zone-master (set my program changes and channels), and I have my midi I/O mode on multi....This part works perfectly.  However when I switch to another performance which doesn't require the VST layer, I find MIDI is still being sent out, and the last selected VST/Program on my DAW plays. How do I disable this for all performances, yet still have it enabled on the performances I want the VST layer on?
