That said I don't care about Lilyponds midi export at all. I want Lilypond to engrave PDFs. Midi export should be done one level higher. Needless to say this is exactly what Laborejo does: One sourceformat with a high enough information density to both generate Lilypond and Midi without any subtle information lost.
