Also might be able to use my midi foot pedal for stop/start/next previous song.
FWIW I have (in a pinch) resorted to ripping all the other keys off a discarded computer keyboard and left just the space bar key .. using that to start/stop with my foot worked just fine.
Whatever it takes to make it work.
Silvertone is a great resource for how to 'get er done' in RB.
He's braver than I, and I consider myself a power user!

I usually resort to PT when going live. For one thing I don't get the 'loading accompaniment' window during a show. I suppose this can be planned for and avoided in RB .. but I like to know what to expect when performing.
