Just curious - I hooked up a ground control pro and also a Rocktron Midimate via MIDI to the Kemper and it was quick and easy to set up. Is it the fear of midi setup or use of one cable that has everyone wanting a Kemper footcontroller?
BTW, if it's one cable, you can get a 5 pin (with power jack) to 7 pin midi cable and run one cable out to your footswitch. Used it with both midi controllers listed above with no problem.
