I've been away from the work stations for quite a few years, so my knowledge is limited to some degree about what they can and cannot do on the fly. If I recall correctly, they were never intended for live performances and quite cumbersome when it came to utilizing multiple functions. I have to agree with Diki--the TOTL arranger is currently the best way to go for live performances, particularly when you are often setting up two to four songs in advance.

Cheers,
