How about this idea? You could pre-build a set set of registrations that match up to a known setlist. In that case, it would be as simple as reaching over and touching the next registration via SD40 screen to configure things. You could even have multiple registrations for the same tune if needed. Of course, if you took a request you have to fiddle around if you didn't have an existing registration that would work. I haven't saved a registration and verified that the MIDI In1 settings are saved but I expecting that they are.
