I wanted to love it, but..
Since the Style is divided into only 4 parts (named "Drums, Percussion, Bass, Other Parts"), it is very limited: the "Other Parts" voice can NOT be changed to any other voices, therefore you can only either mute it, or adjust it's volume. If muted, all that plays are the Drums/Percussion and the Bass. Even though my Yamaha e453 only allows either ON or mute, it IS divided into 6 sections, and therefore way more effective, as you can mute say, guitar or piano, and still have a very full accompaniment.
I always go back to Yamaha
