[CAUT] Tunic OnlyPure Software

[Richard Brekne]

Funny you should mention that David.  Kent claims "magic" several places 
all over his article.... what was that quote from Arthur C. Clark..... 
?   I make the opposite point.  This aint magic, and if you stop and 
think about the consequences of not compensating for individual 
instrument inharmonicity you will quickly see that that claim cant hold 
water either.  In fact Kent quotes  Stopper saying exactly that. This is 
no doubt a fine piece of softeware... but lets not try and pass it off 
for something it isnt.  "Magic" doesnt do Stopper justice at all. He 
spent a lot of hard work and long hours working all this out... with 
maths mind you... so it all does make perfect... and quite rational sense.

 >From RicB:
"...You can quite easily accomplish a P-12ths tuning ..."
 
Let's follow the <thin> clues we have so far.
 
1. Stopper has stated that his tuning is NOT a P-12ths tuning.
2. I've experimented with P-12ths tunings, they don't seem appropriate 
for many types of pianos.
3.  Kent stated that he's tried the OnlyPure on many types of pianos and 
the tuning "worked" for all of them.
4. Stopper's definition of "pure" is not the same as the traditional 
tuner's nomenclature of a partial match.  (something about where the sum 
of beats of all relevant partial matches of octave and octave-fifth are 
at a minimum...)
 
So where does that lead?  Not to a simple Tunelab curve. It's an 
interesting puzzle.  Especially since Stopper seems to discount 
inharmonicity - the software seems to work without any measurements from 
the piano to customize the tuning.
