I’d like to +1 this.
If it’s of interest, my use case for this is that I use my H90 for both guitar and bass, and have been organizing programs into a guitar list and a bass list, just to make it easier to keep them separate.
It would also be nice to be able to change the Instrument Type with MIDI, or perhaps assign different Instrument Types to different Playlists, so that if I’m using my bass list it will always be set to bass type, etc. I could log a different request for this feature if preferred.
