The strange accidental numbering appeared in a second place: \property Staff. keySignature = #'((2 . -1) (6 . 3) (4 . -2))
Here, it is not evident whether the quarter-tone basis is used, or not. One could indicate the basis in the syntax, e.g. the following way: \property Staff. keySignature = #'((2 . -1) (6 . (3 . 4)) (4 . (-5 . 12))) Accidentals, could be named as: accidental-{-2 ... 2} accidental4-{-4 ... 4} accidental12-{-12 ... 12} Greetings, Heikki Junes _______________________________________________ Lilypond-devel mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/lilypond-devel
