Seems the Midi Moose is the right thing for you, it will exactly fulfill your purpose:
- 5 preset-buttons for the 5 presets in performance mode
- 2 banks up and down-buttons for switching the performance mode-banks
For sure it's a much smaller solution if you still want to use your pedalboard.
that is good to hear! I actually was able to just score a used one from guitar center for $100. Not too shabby. this will probably hold me over nicely until the actual kemper foot controller comes out!
