Re: Removing all dynamics from MIDI

[David Santamauro]

After some digging, in note-performer.cc I found

velocity += from_scm (get_property (ev, "midi-extra-velocity"), 0);

After tracking this string throughout the source code, I finally found where the property is set: ly/script-init.ly

accent = #(make-articulation 'accent

           'midi-extra-velocity 20)

marcato = #(make-articulation 'marcato

            'midi-extra-velocity 40)

etc…

I tracked its inclusion through ly/declarations-init.ly and then ultimately to ly/init.ly. I have no idea where init.ly gets loaded so that’s about as far as I can take this. If someone could shed some light on this, I would be grateful.

thanks

Hi, it seems removing the Dynamic_performer doesn’t actually remove performance of articulations. E.g.,

\version "2.22.2"

\include "english.ly"

hits = \relative c { c''4\mp c-^ c-> c }

\score {

  \hits

  \layout {}

  \midi   {

    \context {

      \Voice \remove "Dynamic_performer"

    }

  }

}

How can I get the MIDI to contain only the midi events as pitches and durations, i.e., absolutely no interpretation of dynamics or articulations?
