Unfortunately Western notation doesn't work like that. Accidentals (microtonal or not) operate on the 7 diatonic pitches, not on 12 semitones. I think you think the "arrow" somehow alters already altered notes (like Bb), but the alteration operates on the diatonic notes, so there can be no difference between natural-quarterflat and flat-quartersharp, but C# and Db are distinct. > Graham Breed wrote me a nice note suggesting defining some kind of > override or tweak to redefine the symbol on the fly, but > considering it > I think I'll probably go with 'cheaty' definitions of pitch > alterations,like +/- 101/400 (or 1001/4000 or whatever seems > most appropriate:-) I think that works so well and easy that there is no reason to have anything better :-) Kees _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
