I see where you misinterpreted the thing.
It's not about the number of the CC you must use; it's about the value THAT CC sends out.
Every CC sends out a value between 0 and 127 OR 1 and 128, depending on how the choosen unit is made.
You can choosw ANY CC but it has to send out a value of 64 to activate a change.
Ok?
