MusicXML export: quarter tones need alter element too
Revisions 2645 and 2649 add preliminary support for quarter tones
see http://musescore.org/node/4222#comment-10914
However Michael writes :
"Please be sure to add the alter element as well as the accidental element - for instance, 0.5 for quarter-sharp, 1.5 for three-quarters-sharp, -0.5 for quarter-flat, and -1.5 for three-quarters-flat. Please let me know if that still does not work for import into Finale (I don't know if Sibelius supports this during import)."
MuseScore version: r. 2701
(Operating System: Windows XP)
Comments
For the moment, MuseScore supports only the "drawing" part of quarter tone accidentals and not the playing part.
MusicXML export reflects this. The "name" of the quarter tone is exported but not his playing/alter effect.
For what it's worth, I think finale import current MusicXML well.
OK. Closing for now. We can reopen once MuseScore supports playback of quarter tones and other micro-tonal accidentals
