Many thanks Jean, useful suggestions, but , possibly for my ignorance of technicalities, convert.ly is still not working.
Regarding \numericTimeSignature in \incipit I’m using it with baroque music with clefs not currently in use for voice staffs, not in a mensural context. This feature was working correctly with the 2.20 version. Last: the \set Score.skipTypesetting feature gives error in a first instance, but after a first attempt, is working correctly as in the previous versions.
