Talking about utilities: Has anybody ever seen one that transforms a
simple
voice (pitches and durations) into a "ghost voice" consisting of
spacers and
durations only (e.g. c2 d e ==> s2 s s).
In scheme, it can be quite short :
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
skipMusic = #(define-music-function (parser location music) (ly:music? )
(music-map
(lambda (x)
(let ((dur (ly:music-property x 'duration)))
(if (ly:duration? dur)
(make-music 'SkipEvent 'duration dur)
x)))
music))
notes = { a2-"hello" b4 r b2 a-"bye" }
\skipMusic \notes
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
