Set the sequencer tempo to MIDI. One of the sequencer modes allows 
you to trigger a different sequence on each key. That might be useful 
live. Bring something, a melodica, some bongos, anything in case 
things melt down in the middle of the show. Make sure you have all 
your cables! Tape down your adapters. Check out the last couple of 
Keyboard Magazine articles on playing live with a computer. Get all 
your gear out and actually practice the whole gig in front of people, 
make sure you can pull it off.

Good luck. I'll stick to garage band playing thank you very much.
