Midi learn for previous/next preset in Archetype Gojira X stand-alone app?

Hi!

I’m using Archetype Gojira X plugin in stand-alone mode and controlling it with Morningstar MC6 Pro. Everything else works nicely, but I can’t figure out how to program “Previous preset” and “Next preset” to my MC6.

In MIDI Mappings, there are no parameters/presets for “Previous preset” and “Next preset”. I also have Nolly and Petrucci plugins and both of those have “Previous preset” and “Next preset” in MIDI Mappings.

MIDI learn doesn’t work either. I can right-click the arrow buttons of “Previous preset” and “Next preset”, but when I hit my MC6 buttons, nothing happens. I’ve tested that MIDI learn works for other functions, like transpose or toggling effects on and off.

Does someone know a workaround to this problem?
