Hi,
yes the code was pretty old, about 2007.
So it is good to have updated this topic in the forum.
Thank you to you and everybody!
unofortunately I use Lilypond only once in a while, so I don’t use it enough to
develop a deep knowledge as I would like.
first one who writes a book/tutorial on Lilypond… kudos!
best to everybody
