As a follow up to the recent thread on using the stock SAT tunings VS always using FAC values from the piano. I agree. Use FAC values from the piano. BUT, if for some reason that is not possible/practical/etc.......... I tuned two pianos yesterday, a recent vintage Kawai KG-2 grand (decent piano) and a 1902 Kimball upright (REALLY bad news). On both pianos I could not get an "F" value. I even tried nearby strings. I first zeroed in on the F5 partial and then went tabbed the machine one octave up to measure the inharmonicity, and on both pianos, I could not get a light pattern. The SAT would not pick up the partial. SOooooooooo, what did I do? Rely on my non-existent aural skills? No way. For the Kawai, I used the generic KG-2 tuning. The F value looked reasonable, and the A and C values were EXACTLY what I measured on that piano. Sampled some octaves & double & triple octaves and they were right on. No need for DOB adjustment. Kimball - same thing. I used the Baldwin 52" generic tuning - didn't even check the A and C values on the piano (it was soooooo baaaaad). Check a few octaves, BINGO!, perfect. No DOB adjustment. If the octaves were a bit off, I would simply have used the DOB feature to adjust my octave widths. Yesterday was a good day to use Sanderson's generic tunings. And yes, otherwise I always use measured FAC values from the individual piano (plus I always measure all three of the A strings and average if they are close - sometimes I even measure other strings).
