Gilles: Thank you for your solution concerning \numbr. It is great and is what I am looking for.
I have been using Ez_numbers_engraver for sometime now. It is great to display numeric of pitch name per key signature inside notehead. One draw back is that the notehead need to be large for easy reading. When notehead is large, the staff becomes large as well. The \numbr you provided is excellent. The staff and noteheads remain the same while the numeric equivalent notehead pitch per key signature is displayed below the staff. One question though: Can the numeric displayed above the staff? Thanks again for your solution. Blessing +, Ming. <><><><><><><><><><><><><><><> Le Sun, 28 Oct 2012 23:16:34 +0100, MING TSANG <address@hidden> a écrit: (let* ...
