[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] #3166 Add Mult

I often find pieces which require two consecutive \mark(s). My easy workaround so far has been using a \markup for the second one. But this doesn't work nice when you have a piece with say-two instruments and you want to print either each part on its own and the "orchestra" score. The nice thing about \mark is that it will appear on each singular score and appear also only once in the orchestra score.

as follows:
------------

The LSR for typesetting two opposing fermatas above/below a barline will not
produce desired result when voices converge on one staff. Suggest adding a note
of this, or better yet, how one could overcome this.

Xavier Scheuer responded with a workaround and asking that the shortcoming give rise to a feature request:

http://lists.gnu.org/archive/html/bug-lilypond/2013-02/msg00041.html

as follows:
------------

I use Neil's "multi-mark-engraver"
http://lists.gnu.org/archive/html/lilypond-user/2011-08/msg00157.html
and so far I never encountered any side-effect.

%%%% Lily code

% you should include the definition of "multi-mark-engraver"
% http://lists.gnu.org/archive/html/lilypond-user/2011-08/msg00157.html

markDown =
#(define-music-function (parser location text) (markup?)
   (make-music 'MarkEvent
               'direction DOWN
               'label text))

\layout {
\context {
    \Score
    \remove "Mark_engraver"
    \consists #multi-mark-engraver
    \consists "Tweak_engraver"
}
}

soprano = {
c''2 \change Staff = "lower" d''2
\override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible
\mark \markup { \musicglyph #"scripts.ufermata" }
}
bass = {
a'1
\markDown \markup { \musicglyph #"scripts.dfermata" }
}
\score {
\new GrandStaff <<
\new Staff = "upper" { \soprano }
\new Staff = "lower" { \bass }
>>
\layout {
}
}

%%%% End of lily code

Cheers,
Xavier

PS: I do not think a limitation in a LSR snippet that is AFAIK not part
of LilyPond official documentation could qualify as a bug.
But adding "multi-mark-engraver" features in LilyPond by default could
(should?) be considered as a nice feature request.
