The talk of the momentary switches has me curious. Are you guys hoping to hit the switch and have the machine drop in right in time with ya or what? The idea of turning a drum machine of any nature on in a momentary fashion seems a little dicey to me. I've occasionally used my Boss beatmaker with it ran into an A/B box just so I could shut it off it's output with my foot. But dropping it back in, in the middle of a song seems like it could get ugly...
