Yes, when it is a musical test, over the years the tuneoffs have been pretty close. Unisons, unisons, unisons, may be the best advice for what to stress! But if I read you right about the Wurlitzer spinet tuning: snip We measured all the significant notes which included the 5 A's, the notes on either side of the stringing break on the treble bridge and the highest note on the Bass bridge. This circumvents tuning the entire piano as a first pass and then recalculating the tuning to get the best tuning for fine tuning. snip You guys did a single pass tuning in fine mode after the samples? If so, I think you only got as close as about 3 cents to a fully optimized tuning. As an experiment, today I checked with the Wurli spinet here, and sampled, and typed (and retyped)the results. I'm including a *.gif file of the resultant graph of 4 steps of sampling. Series 1 approximates what you did, and series 4 is the final result. Series 1 - 5 A's and break notes Series 2 - add plain wire notes to just past the treble break (d5) Series 3 - C3 down to A0 Series 4 - finish samples to C7 I started by sampling just A4, then added the other A's. These two graphlines are not shown. It's an experiment I've wanted to do for some time; I wondered how much the tuning curve shifted with additional samples. It's tedious, but if Paul still has the tuning saved, he can type out the tuning from 1- 88, then recalculate, and do it again to see how much the tuning shifts. Also when you wrote after retuning with the SAT III: snip We then turned on the Verituner and played all the notes of the area from C3 through A4 and the piano made the VT patterns stand still in every case, and better than when I was tuning with the VT. snip What did the tuning numbers show? Did you have trouble with the VT display while you were tuning? This is interesting, how you could stop the display using a different machine, and "better"........ But take a look at the graph, in that section of the tuning, and up an octave, there is minimal difference between the curves. Lower and higher, however, that's a different story. and then the conclusion of your comparison: snip I believe this shows there is not a dime's worth of difference in the tuning ability of the tuning programs and in the various temperaments when it comes to listening to music being played. snip I think we should add.... When the pianos being tuned are matched Steinway L's. Moral of the story? I think for the best tunings using the VT, adopt a two-pass method of tuning, even if the first pass is a non-tuning pass. It takes me less than 5 minutes. I believe the results are worth it.
