Partition non mesurée

[Laurent Richard]

J'ai besoin à nouveau de votre aide à propos des partitions non mesurées,

je ne comprends pas pourquoi avec le code ci-dessous, j'ai encore un "C" à l'armure. S
Si quelqu'un pouvait m'expliquer parce que là, j'ai beau chercher dans la doc partout, le bloc "
\layout {
    \context {
      \Score
      \remove "Bar_number_engraver"
    }
  }

est bien placé je pense.

Voici le code donc:

\version "2.12.2"
increaseBarNumber = \applyContext
#(lambda (x)
  (let ((measurepos (ly:context-property x 'measurePosition)))
   ; Only increase bar number if not at start of measure.
   ; This way we ensure that you won't increase bar number twice
   ; if two parallel voices call increaseBarNumber simultanously:
   (if (< 0 (ly:moment-main-numerator measurepos)) ; ugh. ignore grace part
    (begin
     (ly:context-set-property!
      (ly:context-property-where-defined x 'internalBarNumber)
      'internalBarNumber
      (1+ (ly:context-property x 'internalBarNumber)))
     (ly:context-set-property!
      (ly:context-property-where-defined x 'currentBarNumber)
      'currentBarNumber
      (1+ (ly:context-property x 'currentBarNumber)))
     ; set main part of measurepos to zero, leave grace part as it is:
     (ly:context-set-property!
      (ly:context-property-where-defined x 'measurePosition)
      'measurePosition
      (ly:make-moment 0 1
       (ly:moment-grace-numerator measurepos)
       (ly:moment-grace-denominator measurepos)))))))

% Named Increasing BAR
nibar = #(define-music-function (parser location x) (string?)
#{
  \bar $x
  \increaseBarNumber
#})

% Increasing BAR
ibar = \nibar "|"
