Reply to MF3D - What do you use the side buttons for?

Hey all,

I'm in the midst of doing my own mapping for the 3D and am kind of lost as to what to use the side buttons for. I'm so used to using a button for shift and then button combos for alternate shift functions. The only things I can believe of are Loop Size adjust, pitch bend, and tempo shift. I'm looking for other ideas and was wondering what others were doing.
