I sit. Use FC5 pedals (5-button foot controller). I also have a sustain pedal and sometimes a volume pedal. I have Vocal Harmony on/off on button 1, text page down on button 2, sustain on button 3-in case of one-nighters and I don't have the separate sustain pedal-intro 3 on button 4 (for an extra fill) and break/fill on button 5. If I had more feet, I'd have more pedals.
I have the luxury of not having to tear down and set up except on rare occasions. I leave everything set up and all I do is walk in, uncover, plug in, turn on and play!
