[pianotech] Tunic Onlypure Tuner

[John Ross]

Some keyboards sampled an out of tune piano, as their basis.
I thought that was only in the old days.
I can't remember who the worst offenders were.

      Also, I'm thinking this out loud.  I've heard that in Europe tuners
      prefer to tune more narrow octaves than we do here in the States.   Is this true?  If so, I've a sneaking suspicion that what Stopper
      might have done is simply expand everything from what is the normal
      in Europe. Any chance of this being the case?  In other words,
      instead of tuning 2:1 or 4:2 octaves for the temperament octave, his
      octave is between 4:2 and 6:3. Granted, he would have arrived at
      this by mathematical means, and I certainly applaud him for doing so!


    I am not aware of any such tendency.  Stretch discussions are rampant here as well as anywhere else. In any-case  Stoppers work on the mathematics behind this and the basic concept of  P-12ths as a tuning priority has nothing to do with simply expanding on what otherwise is normal. 


  OK. That's great to put my misinformation to rest. 





    I think everyone agrees that 2:1 octaves are only good at the very top.... so there is no fundamental disagreement on that point. Nobody I know here in Europe does that. There IS a good deal of talk about not stretching the tuning...  but these folks who talk about that are not thinking in terms of coincident partials... and really don't understand that vocabulary at all. They speak of a "natural stretch" which ends up always equating to some resultant stretch based on some or another standard octave priority set of aural tuning  tests.


  One of the sounds on my Yamaha Motif synth/keyboard has a Yamaha S7 (I think that's the model #). The treble on the piano that was recorded is so badly tuned that I just can't play it. It is nasty sounding in the treble.  I've thought to record some octaves and post it here, but haven't taken time to do that yet.  So I was wondering if that might be the type of tuning that is done outside the States.




    Hope this didnt get too long... but you put a lot of things on the table for comment :)



  Thanks, Ric.
