I have a Roland MC-80EX with hard drive, I been having a problem where during quick play on certain songs, the sequencer starts to hick-up, stutter, sounding like too much midi info is being sent and the unit can't handle it. I have opened the file and can't find anything that should make that happen.

I played the sequence through my computer and SD-1 and it has no problems there.

Called Roland and they sent me update 1.15 but that still didn't help.

Any answers out there?

Thanks
