AJ, and brickboo........ correct me if I am wrong, but doesn't the Korg make you enter the chords in advance, NOT record them in real-time, while you are playing?
This live interactivity is the backbone of the Roland system........ at any time, during a song, you can hit 'Record' and it will remember whatever changes you play until you hit 'Play', upon which it will immediately start to loop those changes until you either hit 'Stop' in the Chord Seq section (upon which it will vamp on the last chord received until you start playing changes again) or hit 'STOP' for arranger stop.
So this loop can be ANYTHING your imagination wants it to be at the time you think it up........ It can be whole verses and choruses, it can be little one chord vamps, it can be extended changes for soloing over, ANYTHING.
AFAIK, there is NOTHING other than older Roland arrangers (I think the G1000 was the last) that have this ability, and the only people that don't miss it are people who have never used it. Once you get into it, it is hard to do without.
Personally, I blame Roland's demonstrators and salesmen for not educating the buyers about what is the most revolutionary feature an arranger ever had. It was light years ahead of any other Chord memory implementation, and they failed to capitalize on it, and make it a proud 'feature', and now it is gone......... lost in the fog of neglect and ignorance.
Shame, Roland, SHAME ON YOU..........
