Hi David,
Thank you for the swift and precise response. That was exactly it. When I
am in search of new functionality, I usually search this page for keywords:
https://lilypond.org/doc/v2.23/Documentation/internals/scheme-functions
That was how I found the ly:make-score. Is there some way of deducing if a
function is intended to be called directly or is only an internal utility
function?
Best regards,
Morten
