[CAUT] P-12ths was: Tuning a Steinway D andaBosendorferImperialtogether

[Ed Sutton]

If I understand correctly it has no memory. It doesn't build up nformation as it goes, or store samples to calculate a curve in advance of itself. 
It just listens to a note and somehow proposes an offset for that note, then "good-by." Go to any other note and it will do the same. Jump around from piano to piano, and it will continue to tune one note at a time.
[I may be corrected on this.]

  I wonder if it measures as it goes does it violate some patents held by other manufacturers?

  It seems that the device does not calculate curves, since the tuning of each note seems to be a discrete decision.

   

  Is it possible that it measures the inharmonicity of the note, or perhaps several partials, and based upon this makes a decision (perhaps using a collection of of previously established templates), on the place to tune the note?

   

  Perhaps it has a set of ideal curves for various partials, and an algorithm to calculate a "best fit" compromise, one note at a time?

    Well Don, I had read that page, but I was wondering about the actual working of the program. I wrote privatly to Kent to ask what were the features or the actual handling of the machine. It seems (if I understood correctly) that there is no pitch adjustment or pitch raise function, no measurements taken, not to mention file savings. My big question is does the program measure and calculate a perfect tuning for each piano or is it just like 1 tuning file in a box. This tuning file being so perfect that it would fit all pianos...

    This is my question. Before I invest over a thousand dollars in something like this, I would like to see screen shots of the differents features I'm used to with other tuning programs TL, Veritune and CyberTuner.

    Thanks,

    Marcel
