No recording sorry ! Believe me either one is a winner. I like the BK7M because I midi it and I like playing a full size keyboard, my Casio PX350. But I feel you need to FC7 pedal with it work live.
The BK9 has a decent keyboard and everything is there in front of you. The addition of the Organ is a big bonus. So the compromise puts me on the side of the BK9.
Gotta sell some stuff so I can get an IPAD to go with it.
