the S9650 is a killer arranger which I really enjoy playing, great sound......but the "audio drum styles" on my S950 are non usable for my needs,......
they really need improvement in so many ways sonically . Wouldn't be surprised if they drop them totally in future models unless they are vastly improved in sound & ability to edit in some way... My BK although sounded terrific need extensive setting up in advance if your going to use it on stage with styles, etc, their strength is not navigation especially without a touch screen just too many moves to do anything IMO....
