Jeff wrote: Hi Ron, So, for the SAT, did you use the Hamilton (243) tuning preset page? or calculate a new FAC tuning? <snip> I decided to investigate only the "measuring" tuning devices. That left out any of the "template" types, like the Korg M-1200, the peterson autostrobe, or using any preset settings from the SAT or RCT. For the SAT tuning, we used a SATIII; the FAC numbers for that particular piano were 18.4, 6.1, 7.9. I'm not a SAT guy, so maybe someone else can jump in and give some specific answers to your questions. Part of what these machines do is to make assumptions on what the inharmonicity will do based on the measurements taken. It becomes kindof like a dot-to-dot puzzle. If the machine has no way of knowing where there are big jumps, as opposed to smooth transitions in the inharmonicity, the calculation will suffer. On the older pianos that I used, the plain wire starts at Eb3, the newer ones shift at F3, I think. There are a few wound wires on the long bridge. Through some careful measuring, we were able to determine that in that section of the piano, the 6:3 and 4:2 octaves are about 3 beats/second away from each other, so you can set one or the other beatless, or choose somewhere in between. (But you knew how hard that section was already!)
