Alright, the situation is this. My band uses a hell of a lot of samples in our songs including keyboard parts, sound effects and what have you. The problem is using these sounds live. None of the band is competant at playing keyboards and our vocalist, the only one not playing an instrument, has limited motor skills in his hands and as such can't play.

My question is this - is there any way to use these sounds live without resorting to recruiting another member? I think I remember someone telling me about a MIDI footswitch or something of similar ilk, but that was probably to do with something else.

Any suggestions?

Thanks in advance.
