My entire message didn't post, and I tried 3 times! I contacted MPV, and they said they are working on fixing the problem. I'll try again here:
"I'm trying to map Ultrabeat's SEQUENCER to my Edirol PCR-300, and I've mapped the sequencer's start/stop option, but I can't figure out how to map the sequencer so that it scrolls through the individual patterns themselves (e.g. C-1, C#-1, etc.). Is that even possible?
