Pedal drop sounds
Dmitry, I have a Mk 4 C5 Pro, and the pedal noise was driving me mad. I
complained to Yamaha, and a piano tech visited and confirmed the noise I was
hearing was incorrect, so don't let them tell you the noise is normal. The
problem was solved very simply. If you take the piano action out, you will
see the push rod from the pedal trap work connecting to the dampers. There
is a felt washer between the two surfaces, and this washer has flattened to
the point where it was no longer effective. We cut another washer from thin
felt, and placed it on top of the other washer. Problem completely solved.
 
Apparently the sound, though minor in itself, is amplified by the acoustics
inside the piano. I had previously tried slowing the dampers by using
Spencer Chase's proportional pedal software, but nothing was going to solve
this problem other than a felt washer. Good luck with it, and you will be
amazed at how silent the pedal can actually be.
