Alan, The VT is re computing the tuning during the P.R and gather all the iH information, so the second pass is more precise with better iH information. The screen display up to 8 partials in real time. I don't like turning display either (because of my glasses I guess) , but in fact there are markers, that don't move - for P.R. , and when used to the display, nothing is turning much really, or so slowly it is not a real problem. Nowadays there is an (optional) needle in the display that is not turning at all I refer to it a lot. What I like about the tool is the naturalness of the use, I mean I could be back tuning pianos and not managing the partials, stretch or parameters. I generally tune as if the tool where not so viable, meaning I use less test, but still make tests while tuning. At that day when something was wrong, it have been seen that the VT was right, and I did not follow enough it. It is not useful for building tone and tune unisons, but how I see it, once a stabilization pass is done (fast tuning) , I really tune the piano, in the way concert tuners work on instruments that are yet almost in tune. Talking about temperament, the comment make sense, what is computed with the VT in its original mode is A perfect progression of thirds and fast intervals. A very even color of the fifths, fourths and such. And a very clean alignment of partials, when you play large chords, the fast beats produced are really less. If I where to be critical, I should say it is so pure that it lacks a bit of "human touch", but the overall resonance of the instrument is really improved, as the partials align really more that what we can do usually. When tuning after some very good aural tuners, I noticed the temperament was the same that what was done before, assuming they where based on faster intervals. If one is used to allow for more "movement" in it's temperament sequence, I believe it may be advantageous to him to record its temperament , to analyze it in regard of the "perfect" temperament produced by the tuner, and use its temperament preferment to the standard (ET) setup. Indeed then one may discover he is not tuning in a so perfect ET, which is absolutely not wrong of course. When I worked in concert service among 4 other tuners, I could recognize the temperament sequence of each of my colleagues by the little variations they install systematically, in any piano , these always took place in the same intervals (differently for each tuner). So if one want to keep this style before his ears are "corrupted" by the regular use of the tool, that mostly learn you to be aware of more discrepancies than one was before using it. I get used to that perfect progression now, but still I am very attentive at the color of chords and singing intervals, and I have to change the stretch sometime. What was very evident with the RCT, I used for some time, was that the temperament and the tuning was based on an even progression of the 5ths and the twelve's, and, as such it have some kind of "personality" given. Tuning by "pure" 12th is well a procedure for some. With the VT I was reluctant to have so much compromising done at first, but I've actually learned to install unison color at the same time I check the fourth/ fifths color, and that works for me. If not done, one can obtain a very well in tune instrument that is yet sounding awful. I see you point with the PR, one have to get used to some brands and models enough to predict the drift, I do that instinctively too, not being working for a particular brand. Enough of that stuff, I hope some comments can clear the ideas. I guess there is a return policy for the VT if you don't like it (you should check that on the web site) BTW 50 min is more than the time we had for concert tunings sometime, my regular time is less than one hour today, with a refinement pass on unisons (but still 2 hours for a 1/2step PR plus tuning.
