Disklavier

I have the same problem on my 1V prove as well. A very qualified 
techs name is Mark Hullibarger. He is in the Southern California LA 
area. He improved my noise quite a bit. Yamaha hopes to improve this 
some day but he problem is that its difficult to keep a piano 
looking and feeling the same on manual play yet have "tight 
clearances" on auto play.
