Disklavier

I need to amend a few things on my last post about pedal clunk.

First, the Disklavier needs to be turned on to check for the red LED through the slot on the pedal solenoid cover.  There may also be a slight adjustment available in the PRC under service tests or Toolbox.

Second, the capstan referred to is to adjust the pedal lever travel - not piano travel!

Try a genuine Yamaha Disklavier file.  If the noise still persists, try and record and playback test.  You do this by recording a file yourself.  Hit Record, then play each note on the keyboard and then press down  the pedals.  Then play the file back.  If the pedal clunk is on your test file, you probably need the services of a real Disklavier tech to adjust the pedal solenoid.
