Forgot to mention one important feature on my BK9. When you hit the track mute button ( which is programmable ) you get just the bass/drums of a Style. That way you can do a piano trio setup without reprogramming Styles. As you said much more flexible and another reason for 76 keys.

Sorry I got off topic and rambled before. Bored here waiting for Hurricane news. Damn ! they even closed the Bowling Alley so the PD could use it.
