In the last weeks I did write a start of a lilypond -> musicxml solution.
What I have written so far is creating musicxml files which contains all partials time signatures, keys, notes, slurs, ties, staffs and staff grouping, as well as support for most accidentals, barlines, lyrics, beams, tupplets, forced linebreaks and pagebreaks. There is partial support for tempo (only <note>=bps ). Also most header information (title, composer etc) is put in the xml document What not is handled graceful is NullVoice (is just added to the staff). Fermata, CueVoice, Figured bass, stems, repeat endings, special noteheads are not handled at all (at this moment). Also (apart from line end page breaks) no engraving information is added to the musicxml Anyone who is interested in the code can have a look at <https://github.com/de-wolff/lilypond/> https://github.com/de-wolff/lilypond/ in the branch musicxml You only need musicxml.scm xml-library.scm and musicxml.ly. Then you can include musicxml.ly in your music.ly, and put a line \musicxml \mycomplexmusic in it The music can be the total expression as you put it normally in a score, including staffs, staffgoups, lyrics etc. As this is an (old) issue, there is need to put this in lilypond, but how? What level of quality is needed? Who can help me to join the lilypond developer group? Jaap
