I set a piece a while ago using Lilypond 2.19.48. It consists of 2
staves, and I used \mark for some annotations that I wanted to appear
above or on barlines - mostly the "crotchet - dotted crotchet" type of
thing. Sometimes these only applied to one of the staves, so I would
specify the mark in the music for the appropriate staff. I added:
\layout {
\context { \Score
\remove Mark_engraver }
\context { \Staff
\consists Mark_engraver }
}
and it all worked just as intended.
I was recently asked to make a new version of the piece. The main
change is from a male voice to a female one, but this necessitated a
few changes in the other (instrumental) staff. I ran convert-ly on
copies of the original files as I now had Lilypond 2.23.4 installed.
I then edited these to produce the new version
Unfortunately the behaviour of RehearsalMark seems to have changed.
Whereas previously a mark only appeared over the staff whose music it
was specified in, I find that now all of the marks appear in both
staves, regardless of which staff they are intended for.
Is this a bug or an intentional change? And is there another way I
can use marks to get the result I want and previously had?
