Thanks for the info about FS1 and FS2.

I wonder what the design logic is that requires you to change to play mode in order to select one of two presets in the bank, and then change back to bank mode in order to continue banking up or down. While we are wondering about that, my midi foot controller can be assigned multiple commands for each button press, so it can handle this.

But I haven't seen anything in its manual that would allow it to increment or decrement program changes with a single button push.
