Re: Separate dynamics from notes

[Gianmaria Lari]

Thanks Leo, very interesting!

I report here, for other users, your same example adding the command displayLilyMusic at the end. 

When compiled, lilypond outputs (in the standard output) the resulting music _expression_. For example for the following code:

\version "2.25.4"
%%%%%%%%%%%%%%%%%%
convertToSkips =
#(define-music-function (music) (ly:music?)
   (music-map
     (lambda (m)
       (if (or (music-is-of-type? m 'rest-event)
               (music-is-of-type? m 'note-event))
           (make-music 'SkipEvent m)
           m))
     music))
%%%%%%%%%%%%%%%%%%

music = { r2\p <e' d'> c'4( d')\ff s4 r4 }

music = { r2\p <e' d'> c'4( d')\ff s4 r4 }

\score {\music}

\displayLilyMusic \convertToSkips \music

this is lilypond output:

Take care with things that ar still interpreted, like Scripts.
