You make a very good point regarding the need to go beyond plugging in FAC numbers, using offsets and expecting a great Valotti (or whatenver HT) tuning on the piano. Such use of the SAT (or any other VTD) is nothing more than a machine tuning (even if only used for ET) that might be OK (perhaps on a well-scaled piano) or more likely be off ranging from a bit to LOTS! I have only tuned a few pianos with the Valotti, Young and Meantone HTs. In the absense of any suitable aural checks for these tunings - and lack of knowlegde of how to tune them aurally - what I did was to work out an ET tuning (with appropriate aural checks) that I was happy with (essentially an aurally modified FAC tuning - as are all my tunings) and record this in the SAT (there are a variety of methods to save the tuning). After I am happy with the ET, I enter the HT offsets to that tuning and proceed to "machine" tune the piano with the SAT. Actually, most of the pianos I have tried HTs on are pianos that I had tuned previously and have an established ET tuning for them. I'm no expert (just getting into the adequate range) ET tuner. Only experimenting with HTs. Is mine a logical approach that is likely to yield good results?
