My controller has a knob which is CC64. And a note which is Note# 64. And Modul8 confuses these... pressing the note will cause the value bound to the knob to jump around, binding the knob may cause the note binding to disappear, etc. Looking in the saved project, it seems like the file format isn't storing the MIDI event type at all. Bindings seems to only care about channel number and event number.
