Really nice controller that I no longer have the time to use. It's been in its sealed box for a while now and powers up just like it's supposed to....I just don't have any midi interface to use it with to test any further but no reason to think there could be any problem.
Comes in it's original box, has the manual and detachable sheet music holder, I even have the optional a/c power cable (unit also can operate on battery).
