Digital players in high end pianos

[piannaman at aol.com]

 Thanks, William.? I've seen that system on the better installations.

Another thing: in order to accommodate the solenoid cutouts in the back of the keybed, one or two of the keyframe guides are usually removed.? On a couple of pianos I service, I'm having a devil of a time bedding the keyframe so the front rail doesn't knock without there being a squeak/creak/groan from the back end of the frame when operating the una corda peda.? This seems to be related to the missing guides.? Any suggestions on this one would be welcome.

HI Dave,


?


I share your discontent.? Mostly 
from the perspective of people and their passionless things.? It is 
tragic.

Re: the QRS system, one thing I've 
found to improve pedal performance dramatically is to take a coil spring and cut 
it to an appropriate length to fit under the damper pedal trapwork, just in 
front of (or behind, if there isn't room)?the pitman.? This does 
wonders to restore the usefulness/normalcy?of the damper pedal 
function.

Today I was called out to check 
  out why the keys weren't working on a Shigeru Kawai SK2 with a QRS disc system 
  with all the bells and whistles.? I'm not a big fan of these syustems, 
  because I feel that they interfere with the way the pianos operate in many 
  cases, particularly if they aren't properly installed--specifically, the 
  operation of the pedals.

Anyway, this QRS system has a "quiet piano" 
  feature which has a rail poised just above the hammer shanks that is raised 
  and lowered by a cable that's attached to a pully system operated by a lever 
  on the right cheek block.? I'm sure some of you are familiar with 
  it.? 

This was the first time I'd seen one.? I thought it was 
  pretty Mickey Mouse.? The cable had come slightly loose? in the 
  turbuckle and was not able to raise the rail above the shanks high enough so 
  that the hammers could hit the strings.? 

I was able to get the 
  show on the road again, but not without asking myself (not the owner, who 
  spent the whole time I was there talking on the phone with gardeners, 
  electricians, and contractors about the things that were wrong with her 
  gazillion dollar home) why anyone would put this thing on such a nice 
  piano.? It was evident that this was just another thing amongst a vast 
  army of expensive things, none of which was really an object of the owner's 
  artistic passion.

I guess if someone has the money to buy something, 
  they deserve to have it.? It's just unfortunate that many people who 
  spend their lives devoted to music will never be able to afford such an 
  exquisite piano.
