I'm sorry if this has been suggested before. I searched and could not see it.
One (seemingly simple) software suggestion I have is to have numerical feedback on the display when you change a knob. For instance, when you adjust the volume knob, the display will turn to a number corresponding to the volume you are currently set at. For pan, it would say something like L30 or R22. This would ideally hold for a few seconds and then go back to whatever is was displaying previously if no other knob setting was changed.
Thanks for listening!
