Re: markup superposé à la barre de début de système

[martial]

Gros bidouillage 
pour  3 systèmes 

%----------------

\version "2.20.0"
boxRed =\markup {
 \with-color #red  \filled-box #'(0 . 2) #'(1 . -12) #0.1
} 

floatMarkup = #(define-music-function (parser location posx posy) (number?
number?)
                 #{
                   %\once \override TextScript.outside-score-priority = ##t
                   \once \override TextScript.X-offset = $posx
                   \once \override TextScript.Y-offset = $posy
                 #})



\new ChoirStaff \with { \omit Clef \omit TimeSignature  }
<<
  {
    \floatMarkup #'-12 #'1.0 c''1_\boxRed \break
    \floatMarkup #'-25 #'1.0 c''_\boxRed  \break
    \floatMarkup #'-25 #'1.0 c''_\boxRed  \break
  }
  {
    c''1 \break
    c'' \break
    c'' \break
  }
>>
