Can we get a more specific example of different keys having different modulations? That’s possible to program via velocity, splits, and key number only so beyond that it’s impossible with the architecture. So to narrow it down to one of those would help us diagnose. Also I assume we’re going straight prophet here and no DAW when it comes to trouble shooting? (I use ableton with mine, I’m not anti daw, I just think it should be removed for trouble shooting)
