Hey Lucky,
I'm curious - you said you played Roland all your life, and yet you don't like the piano sound in the new series? My thought is that Roland has ALWAYS had about the best pianos out there, and they got better with each new design. If the interface was different, and the mixer as complete as Yamaha ..... I'd go back to the Big "R", but for now ...... it's only the operating system that keeps Roland off my stand.
Just thoughts.
