Here’s what some of the manufacturers say about tuning: Steinway & Sons … Unfortunately, no matter how expertly a piano is tuned, atmospheric variations, particularly humidity, and the nature of the piano’s construction constantly conspire to bring it off pitch. Your Steinway piano has been designed and built so that in normal use and under…
Lowering the tenor partial change to G#2/A2 results in a full 2-octave (A2-A4) range with all notes within that range using their 4th partials for the tuning. Not having any partial changes within the A2-A4 range, makes the tuning more accurate by eliminating even the possibility of a partial change error between A2-A4. In the treble, using the 1st partial instead of the 2nd @ A5 makes determining and tweaking the treble stretch easier.
Contained below is a random collection of some of the tuning ‘listens’ recorded with my iPhone. In the collection are grand pianos of different sizes and manufacturers, some studios and consoles.

I have two SATIV “980”s. I use them both, one one week and the other the next. I don’t want to work without one. And, since a Microsoft Surface Pro is part of my tuning process, I have two of those as well. I’m backed up with both hardware and software. It’s great to know…
All ‘computer generated’ tunings have partial changes and those partial changes may contain an error. Correcting these partial change errors can greatly improve the sound of the tuning. The number of partial changes contained in the ‘computer generated’ tunings will vary depending on the ETD. This procedure will show how to use the Partial Change…
The field of Piano technology is an unregulated trade. Therefore the Piano Technicians Guild has set its own standards of quality for piano technicians.
Start by setting the SAT’s ‘Up or Down Memory Storage’ to DOWN. The STO/MEM + Note UP or DOWN command sets the direction the SAT will automatically go, after a note is stored. Press BluShift and then STO/MEM to store the settings for B2, A#2, and A2. (Contains button pressing video).
When using the A2-A4 range for tuning a 2-Octave Temperament, all the notes within that 2 octave range need to use their 4th partials. This eliminates any possibility of a partial change error in that A2-A4 range. (Contains button pressing video).
The need for this tweak has been around for some years now, but it should be used whenever using an FAC tuning. (Contains button pressing video).
