I believe it depends on the instrument.  On the piano, C1 is the first

C, which makes middle C C4.  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.
