Hey gang, I'm now using my XW-p1 as a master controller and my ctx 5000 for my 2nd keyboard. How can I change the Registrations on the CTX 5000 by midi? I don't want to change the sounds in the Reg just recall each one for what I need. The XW P1 I understand, just can't get the reg changes. I want to push one button on the XW and have the whole rig change to what I want for programming.
