I don't have a Yamaha grand within easy reach to check this on, so I couldn't tell you if it's a semitone up or down but it's very consistent...not a mistake. Whereas Fazioli will tune those cute little gizmo's perfectly to whatever they have decided on each part of the piano. Curious... Cheers Mark Bolsius Bolsius Piano Services Canberra Australia
