On a pipe organ, however, which generally has 61 notes on each keyboard, C1 is the first C on the keyboard, which puts middle C at C3 which an 8' stop, which is the standard footage when counting notes. I guess from what others have said, Yamaha uses the pipe organ numbering (which makes sense on most synthesizers with five octave keyboards), while others are using the piano numbering. Chuck
