Most PianoDisc pianos are made by Young Chang. The most common cause of
release noise is the knuckles for which YC's reputation precedes them.
You can brush them, with a suede brush, lightly file them, kneedle them,
coat them with teflon powder (see Spurlock) and the noise will be
reduced temporarily. Good luck.
