Is it possible to browse the presets using a hardware midi controller? I'm basically looking for a midi control change for the "Preceding preset" and "Next preset" buttons.
If you use the synth Sound Map in list mode, then you can use your computer keyboards arrow keys.
Perhaps your controller can qwerty assign so you can control the arrow keys from your controller and thus the preset selector.
Unfortunately it's only for some factory preset's.
Using automation have ProgramChange possibility inside current subbank. Perhaps if you can't do the above qwerty assignment, then you perhaps can configure a control to step selection in a automation enviroment.
Don't know if ther are other ways.
Hope this helps.
