> I'd like to see a booklet of FAC > numbers for every conceivable Why? I have found that FAC numbers change seasonally so I take new numbers at each piano for each tuning except for those I have optimized. Taking them is so fast and easy there is no point to having more than a few master tunings for the concert instruments. It would take more time to look them up and program them in than to just take them off the piano. Newton
