This one was a bit frustrating to create. Aside from the need to use Momentary switches (it would have been nice to use a List Fader to choose Oscillator octaves, for instance), there are several controls on the Memorymode plugin that are MIDI assignable, but you are unable to access the popup list via MIDI. These are:
Keyboard Mode- Poly, Mono and Multitrigger;
Number of Voices;
Arpeggio- Mode and Range;
So, I have a support request in to Cherry Audio regarding this. But try this out and let me know what you think!
