Jim, Thank you for your responses on this forum. I've been lurking & learning from this subject. I've some questions. So, how do you incorporate the dual FAC on a poorly scaled piano? In the past I've liked strip muting it off, checking my A2, A3 & A4 to find out if they worked (especially as a double octave). Then, I use the SAT to tune the temperement on the 2 different pages. With it stripped off, it seems very easy to find problems using contiguous 3rds. Just recently I was tuning a Baldwin SF, and to my horror, there were about 2 beats per sec. between A2 & A4. I carefully checked my stretch numbers, (and didn't add the .2c to the A number) and the double octave slowed down to an acceptable level. It seems to me that I would not have caught the bad stretch # until late in the tuning, requriing another pass, had I not strip muted it off. What exactly do you consider a pitch raise? Or, how many cents correction requires two passes? As I understand it, you start with the plain wire strings. Does that mean you initially ignore any wound strings on the tenor bridge? I would assume that you start with the highest wound string and then go down, eg. Bb-26 descending to A1. How much drift do you encounter? Like .1c or .2c? So you just RESET the SAT for that much pitch deviation and go on? ( I hate drift!) Again, I really appreciate you sharing your wealth of information. THANKS!!! Larry Gardner, RPT
