Thank you for viewing. This item was purchased in 2014. Upon listing, I performed simple operational checks on the controller, buttons, etc., and confirmed that they function without issue. (This was only a basic check, so I haven't verified every detail.) I confirmed that USB connection and MIDI sound source functionality worked without problems in 2014. There are scratches on the back and sides (see photo 3). Please understand that this is a used item before purchasing.
