Thanks, Don Palmire </BLOCKQUOTE> Anything over 25 cents low, measured at A 440, should be considered a pitch raise. Off set the SATIII 25% higher that the pitch was low. (If the pitch was 40 cents low, off set the SAY by 10 cent sharp. The do your normal FAC, (or use a preset temperament, and tune the whole piano, like you do a normal tuning. Then turn off the machine, and do a normal tuning. On the pitch rise, you don't have to get picky with the unison. But the close you can get with the pitch raise, the less time it will take to do the tuning. Wim </HTML>
