I know most of the time people ask how to make things polyphonic with poly~ but I want to do the opposite. I am trying to replicate the "Poly/Mono" modes on a synthesizer. In mono mode, the typical behavior is when you press the second note, the first one stops sounding--that part's easy. What I want to be able to do, though, is if you continue to hold the first note and release the second note, the sound jumps back to the first note. That's the part I'm having trouble wrapping my brain around.
Any tips, hints, suggestions? Thanks!
