Hi all A side by side comparison of the Tunic to your SATIII? Whatever it is... i.e. tune with the Tunic then take readings with your other ETD. Like Jeff and others I would be interested in what differences you find, if any... David Ilvedson, RPT Pacifica, CA 94044 Given the discussion so far, and the comparisons to Virgils style of tuning... and for that matter the background of discussions / debates surrounding Virgil Smith and ETD's in general... with Jim Coleman on the ETD side of the debate... I would think the far more interesting comparison would be to see how the P-12ths idea lines up with Virgils tunings. Easily done really.. Get Virgil or one of his disciples to do an aural tuning, and then see what Stoppers software would <<correct>>. Measure the cents offset difference. Personally, I would not be at all surprised to see the two line up quite favorably....which would beg several interesting questions as to tuning styles in general, and the effect of the Octave Types approach as put forward by the onset of the original single partials calculated inharmonicity curve approach. It might be a good idea in all this to remember what an ETD (including Stoppers) can and can not do. An ETD can listen for a given frequency... or at best several frequencies at once with an advanced weighting algorithm to decide the fudge factor. I'm not sure even Vertituner does things this second way when it comes down to it.... tho that information has not been published. More likely it has decided a given notes frequency ahead of time based on previous sampling. At best, Stoppers softeware could perhaps manage that... tho given the capabilities of the hardware its written for that is doubtful. So one is left with what has been said about his P-12ths approach and the main contours should be fairly clear. That they should compare (if that is the case) favorably with Virgils style raises a very interesting question and clue as to the nature of the so called Natural Beat. That this all should in turn compare favorably again with other P-12ths approaches through time should then also be no suprise... but again be very interesting in terms of the whole octaves priority vs 12ths priority approach. And... it could possibly tell us some very nice to know pieces of info about why we choose stretch degrees the way we do. A comparison between SAT, Cybertuner, and any 12ths approach should be rather predictable to begin with... and fairly uninteresting I should think. Compare Bernards software to Virgil. Cheers RicB
