Often times, I find that factory reps do not really know much about the very products they demonstrate and even give the wrong information. Then whoever hears the wrong information becomes a false prophet against one’s will. It is amazing how the Yamaha rep could tell you such misinformation when the YC can actually send and receive so many CC messages from every single button and slider as in the data sheet. In fact, I am surprised that YC is so capable as a midi controller.
