I'm surprised this targets TeX rather than lilypond, which AFAIK is the gold standard for free (as in beer and speech) music engraving.

I checked, and lilypond also offers features for Gregorian chant notation [1]. Has anyone used both and is able to compare?

Good question, they considered it at some point:

> Lilypond is a very good tool, but the part on Gregorian chant is not maintained and very deep modifications would be needed to perfectly align the notes and text.

> Note, however, that there are some serious flaws in LilyPond regarding Gregorian notation (especially the non-modern version), and right now there is nobody who works on improving that...
