[pianotech] Tunic Onlypure Tuner

Indeed.  Up until about 6 months ago starting with Bernards first 
appearance on CAUT I was accused by said of ripping off his concept.  
What was that first post he wrote 6-7 years ago..... Started with 
something like "Thank you for using My P-12ths tuning.  That continued 
in off and on fashion until after being challenged to produce the 
evidence of prior knowledge I'd claimed all along I finally responded by 
posting the month and year of  Garys article, which predates Stopper by 
some 6 years. Now all of a sudden we are talking about two completely 
different tuning approaches. Equally sudden is the disappearance of the 
maths behind what Bernard calls the Stopper comma from his website... 
and from Wikpedia where it was quite evident until just a few months 
ago. Googling "Stopper Comma" yields to following link which used to 
hold the document http://www.piano-stopper.de/html/stopper_tuning1.html 
The only reference to that I can find is now at www.stopper-scale. com/ 
Stopper Scale  which in itself starts off repeating the central 
affiliation to P-12ths.

As far as your clues below I can only say that point number one is 
really not quite what he said.... nor have I said the P-12th thread I've 
been following along these years is strictly based on absolute perfect 
3:1 12ths. Secondly... if you couldn't possibly have thoroughly 
experimented with the approach or you would most certainly find how to 
implement it on just about any piano. Dinky little spinets cant be 
"tuned" in the conventional sense of the word period... and no protocol, 
Stoppers included is going to change that.  Its is in the nature of 
these beasts themselves and everyone knows this. I can guarantee that if 
Kent can find a small piano that responds well to the Stopper 
software... I could tune it quite nicely with my approach as well.

As to your comment about matching just two partials. This has been the 
basis for discussion .... not some absolute thing you simply do not 
digress from. That said... if you do slavishly impose a 3:1 from D3 
upwards you'd end up with a very nice sounding treble. And including the 
6:1 and 6:2 in the bass you'll end up with a very nice bass. 
 
I agree... it is all very interesting.... and from a very rational point 
of view.

Cheers
