[CAUT] 1/4 tone piano conversion

Hey, I didn't think of that, Jim.  I am going to discuss this with our
electronics people here and see what is possible.  I know that one can
put custom tunings and temperaments and such into our high end
keyboards, but I don't know how extreme they can go.

More later . . . .

Andrew,

I hate to say a dirty word here but many electronic keyboards (booo!)
can be programmed for various applications. I had one years ago that
would split the octave many ways. (I think up to 31 notes?)

If he has never played on such a piano or seen even one maybe he simply
doesn't have an idea what he really wants. If he has, and knows exactly
what it feels like to play on then that's a different story...

He explained it to me as an upright that had been converted.  Quite
possibly it was two pianos as described.  I'll have to pin him down on
more details.  My first reaction was, you can't do that with this type
of piano, you'll have to buy a Sauter Microtonal piano (problem is it
does 1/16" tone)
http://www.sauter-pianos.de/english/pianos/microtone.html.
He was insistent on the possibility and then I explained how bass
strings would break and how the treble would go dead.  Not having much
experience here I said I would inquire into the possibility of
re-scaling the piano to do the job.  I think I have the answer though.
:-)  Much easier to do two especially when playing...imagine one octave
every 24 keys.  He could...
