Is there some way during a live BIAB performance to cause all instruments to stop and then manually trigger (with a button or foot pedal) either a 4,8, or 12 bar drum or bass break (Real Drums sequence or a custom wav or midi break) and after the break is done to resume the BIAB file's playback ?

I am a piano player. During a live gig I'd LOVE to be able to do this.

If BIAB can't do this, how would I accomplish this ?

Thanks for any hints,

Bob
