I love Casio pianos, but I have an issue with my Privia PX-160. I have this piano for 6 years, and one of the black keys in an area on the keyboard where I usually play, plays an extra note when i lift my finger off, but not if I hit it softly. It also depends on where I hit the key. Maybe it's a general issue with digital pianos, not typically Casio, but could it be dust accumulating? Or is there another problem that could have caused it? And how to get rid of it.
