The DMC's are MIDIot proof and I can prove it because mine works. There is no midi programming required at all . Just go into setup as described in the manual set the DevA to Chase Bliss on A then save and make sure your C4 is set to midi channel 1 that is it and it is all explained in the manual . And you have to update the DMC before before you it will work with the C4 but that is simple too. Although I screwed it up the first time . If you get one and want help from a fellow MIDIot feel free to PM me.
