You need to send midi cc#102, and choose a value of 0 for bypass or 127 for engage. Every cc needs a "value" sent along with it, ranging from 0-127; so these are the specific ones that work for these functions. It's working great for me...
Yes you're right, they should use native translators with a good knowledge of music equipment. With a good manual, they would sell more products I'm sure.
how do you do this on a Musicom MKIII - likewise I'm finding the manual very hard to understand, which process is for the CC#102 and how I get the value on 0 ?
Not to beat a dead horse and suggest to spend even MORE money, but I really can't recommend enough the DMC midi controllers from disaster area. Matt can program them to do virtually anything midi-wise, and you don't have to deal with the proprietary weirdness of some of these other controllers. And then if your midi needs change in the future, you can always have him write new firmware and update the pedal.
