Laurence,
I am in complete agreement with you (and, of course, with Sir Duke!) that, "If it sounds good..., it
is good." Whether I tune this piano as I normally would with Cybertuner, or by ear, consistent, musical stretch and beautiful, stable unisons will always sound good, regardless of the amount of stretch chosen.
The object of this thread, however, is to determine the best practice for maintaining the stability that my colleague (and former trainee) has built into this piano, despite the fact that our respective Electronic Tuning Devices speak different dialects between which facile translation is not possible. When the usual tech returns to this gig, I want the piano to be as close as possible to where it was when he last serviced it. One reason he approached me to be his sub is that he knows I will honor and respect his
work and make no attempt to "poach" this prominent and lucrative client.
Always good to hear from you!
Alan

I wouldn't worry too much about the numbers. Sometimes perfection on the dial just won't sound right to the pianist. Trust your ears. I'm reminded of Duke Ellington's remark, "If it sounds good and feels good, it is good."

Decades ago (! Verituner isn't really the 'new kid' on the block anymore!) Dave Carpenter warned me not to use the target numbers displayed in Fine mode as inharmonicity data. That information is buried a little deeper. While graphing the target numbers will give a general sense, it is best not to accept that as where each partial would be measured in the piano once tuned. For Verituner users, I've found it valuable to step through the tuning while observing the partial progression for each note. Often there will be notes where the partials seem 'out of place', where the spread of partials doesn't match the surrounding notes, or the progression would indicate negative inharmonicity. With careful remeasuring, often I am able to achieve much more consistent target numbers - sometimes this makes little difference at the spinner level, other times it can solve problems.

If the tuner used Verituner to tune that piano and saved the tuning, the resulting vot file contains the inharmonicity data and that's what this graph shows -- for each partial of each note, how many cents is it north or south of "perfect".

Thanks so much for chiming in, and for your offer to assist with one fo your graphs. I have requested the "vot" file from the regular tuner.
The piano is a Steinway D, and the tuner uses Equal Temperament, stretched to Koval Universal 2.6. But Jason, wouldn't you need inharmonicity data from this particular piano, or else what we would have would be a generic tuning?

I've developed a way to show a tuning design visually, by taking the Verituner data and importing it to Excel. See for example this graph below. If you send me the *.vot file for that tuning, I can make this graph of that piano. Alternatively, if we don't have the *.vot file, if you specify the type and size of the piano, we can apply the Swafford P12 or any of the Koval styles.

Greetings,
A colleague has asked me to cover for him at a recording studio. He tunes the piano in question with Verituner (which I am unfamiliar with). I regularly use iRCT (aka Cybertuner) and am also conversant with Sanderson Accu-Tuner.
The best way to maintain stability is to routinely tune the same piano to the same temperament, with the same stretch, and at the same pitch. In that interest, I want to replicate his Verituner tuning with Cybertuner. If I understand Verituner correctly, the stumbling block seems to be that it tunes while listening to multiple partials, apportioning different amounts of weight to different partials. iRCT and SAT, on the other hand, tune to a single partial.
So, the question is: How best to transcribe a tuning from Verituner to Cybertuner (or Accu-Tuner, for that matter)?
Anyone out there done this, successfully? In the absence of actual experience, speculation is also of interest.
Thanks,
Alan
