Dear piano player, I'll bet you get alot of response to your question and here is my two cents worth. I would start with the obvious which would be to check the key easing. My experience with that brand has been that the problem could also be center pin sluggishness. If the keys are staying down partially then I would check the jack centerpins. Young Chang damper actions are also known to have tight centerpins. I don't think the damper action would have anything to do with the keys staying down but I would sure have your technician check all the center pins, especially if the piano is in a lounge, resteraunt, etc. Doug Hershberger P.S. It is probably obvious to you savy computer people, but I'm new to pianotech and just wanted to say hello and tell you how much I'm enjoying the various discussions.
