[pianotech] Self-tuning piano

[Gerald Groot]

http://www.pianoworld.com/forum/ubbthreads.php/topics/1828641/1.html  Here
is the same video clip posted on Piano World from Don A. Gilmore who posted
it himself.  Along with this are comments that are still being made about
it.  

 

I can’t help but wonder things like with it heating the strings, what might
it do to the damper felts over time?  Or, what will happen to the voicing of
the hammers, if anything, from repeatedly hitting the heated wires?    

 

Also, from what I understand, this thing is “supposed too,” tune it with the
push of the button and then, when you are finished playing the piano, you
turn the unit off and, the piano goes back out of tune again.  What good is
that?   

 

I mentioned in that thread posted above, something about; what if the piano
happens to already be ¼ of a tone flat which happens here mid winter in
Michigan?  Heating the strings will make it flatter still but, I received no
responses about any of that
.

Thw engineer who designed a prototype for the self tuning piano applied for
a membership in the PTG several years ago and attended a meeting of the KC
PTG.

When I talked with him he seemed somewhat unaware of the many aspects of
piano technology (causes for a piano changing pitch, pinblocks, etc).My
understanding is that the trial with a piano mfgr. was unsuccessful and had
been scrapped.
