Hey zwolf,

We're pretty sure there's an issue with H9 Control at the moment, where program change mappings  are off by 1.  

So in H9 Control, Program Change 1 is mistakenly corresponding to MIDI program change 0. Program Change 2 corresponds to MIDI program change 1, etc.   

This also means, that programing a change from the H9 pedal itself would look wrong in H9 Control.  Assigning MIDI program change 5 to load Preset 5 on the H9, would register as Program Change 6 loading Preset 5 in the H9 Control app.

I hope this makes sense.  We're working on resolving the issue!
