Another vote for some kind of choice in the way the round-robin works. I'm doing a lot of repeated arpeggi à la Philip Glass these days, and it's quite frustrating to hear the same samples everytime. Maybe you could put this option (total random RR vs cycle RR) in a place for Expert settings or something.
Anyone every get any word if this ability/update is possible? I agree it would be EXTREMELY useful to have more control over how VI reacts to repetitions/round robin programing. With Play pro's potential ability for users to create their own scripts, I really hope VI will eventually allow "power users" more control over how VI performs.
