Hi there, I have exactly the same problem, I can't use the pads, and many of the other knobs that the controller bring. I have found how to solve the problem with the transport, you can find a driver for that in www.muratnkonar.com, but what about the other buttons? I bought this in guitar center and the guy there told me it worked perfectly with GB, what an ***! The thing is I live in Uruguay, and I can't change it now, is there any solution?
