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.
