Although RolandUS's general tech support and marketing of arrangers leave a lot to be desired, I will say one thing for them. I had a hardware problem during warranty (right at the very end of it, also!) and they bent over backwards to help me get it fixed with NO downtime at all (well, one day to take it to the local dealer and have the parts put in - pretty good!).

They basically had no positive idea of what was wrong, so they replaced out nearly every main board (three of them) just to be sure they got it. At considerable cost to them. I was back on the gig the next day, problem solved!

Now THAT'S service!
