Cassp...the Casio that Beaky bought does not have dedicated Midi in/out ports.

If Casio is what you want, you might want to look at the PX-330 which does have Midi in/out, and only weighs 24 lbs...should work fine with the BK-7m.

It also has a pitch bend wheel...that should be very handy for using with the Roland.
