Re: Separate dynamics from notes

[Leo Correia de Verdier]

If not too late, here is an example, based on Jeans code in 
https://lists.gnu.org/archive/html/lilypond-user/2021-09/msg00209.html

%%%%%%%%%%%%%%%%%%
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))

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

%%%%%%%%%%%%%%%%%%

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