Audry. I am hoping the man from the "keyboard hospital" can help
find a new part. I dont think that the wheel can be repaired. I am waiting to hear back from him. Meanwhile I am having a play around with the keyboard - I would hate to have to return it. Turning it slowly does work if you only need to increase a small amount, but reversing to slow down is pretty hopeless.
My fear would be that it is on the way out and soon may not work at all. Thinking about that- I'm in the same boat. Ha Ha.Jean.
