The best demo person I've seen to date from Roland is Dr. Scott Tibbs. He has done many videos for Roland..., and is a great player too. He's the one who did the very extensive GW-7 demo.., and played a nice piece at the end. He has also done many Fantom demos, V synth demos, and a few others. I've seen some nice demos by Ed before, but this clearly isn't one of his best.

It's really odd too as this is Roland's new budget arranger and they still have yet to post a great demo of someone playing the thing. Oh well.., we'll just have to wait for them to start popping up on YouTube I guess.
