I've had mine hooked up to my Fantom G7, VP770, and A70 KB controller.

w/Fantom G7 --- most flexible
w/Roland A70 -- most control
w/VP770 ------- most FUN

Great sounding module, just not a huge fan of Roland styles (because of the kind of music I play - the quality is actually very good within it's genre'). Very easy to use, IMO.
