i'm new to Patchwork!
1) How do i midi assign previous/next preset buttons? Are those not available for midi assignment?
2) The most awesome thing would be to be able to midi cc assign individual presets. That's a feature request i had for Komplete Kontrol for a long time. In Omnisphere for example, this is possible. You rightclick on any preset in its Browser and get the option for "midi program change / cc / note learn".
The reason why it's awesome to midi-map presets:
I build custom Touch OSC (touch control) interfaces, so i can create a visually awesome instrument selector on a touch-surface, to choose VSTs/Instruments from via touch. When chosen/clicked, the specific Patchwork preset would get loaded. That would be the vision, awesome for quick instrument selection for live performance
