Hi Mario,
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.
I'm the one responsible for the change in \numericTimeSignature, and as far as I can recall, the interaction with incipits was not investigated at that time, indeed.
Can you please provide an example ly file? Lukas
