That litany of great arranger features above that Roland do not have is balanced by the fact that NONE of them (IMO) have anything NEAR as live a sound as the Roland's do.
You
ARE kidding aren't you????
Don't forget you are talking here to a former G70 owner (who gigged with it extensively as well) and tweaked all the styles, and was running expansion cards, etc etc ....
I have direct first hand experience with the G70, the Yammies and the Korgs...The Roland is reasonable, Yamaha very ordinary, but the Korgs and Ketrons stand out a country mile!!!
You REALLY have to take of your rosy, antiquated OS, dinky sounding Roland glasses....
