Hello Jacques,

yes, you are right. Any information without a "first class citizen" will 
not be exported right. One might think of additional properties to give 
an export specific attribute - that is to say: this markup shall 
indicate swing tempo in MusicXML. But before that I want to be able to 
export the major exportable elements. And like Libre Office warns when 
you save an MS Word document that there might be elements that cannot be 
exported as expected this export function should do the same ;-)

Hello Jan-Peter,

Thanks for the information.

Exporting to MusicXML is difficult, also because there are things that 
need to be done in LP with Scheme code since there’s no ‘first class 
citizen’ to do the job.


This leads for example to the use of markup for things such as the swing 
tempo indication:


tempoRelationshipStaffReduce = #-3

tempoRelationship =
#(define-music-function (parser location label parenthesized musicI musicII)
    (string? boolean? ly:music? ly:music?)
    (let* (
            (left-paren (if parenthesized "(" ""))
            (right-paren (if parenthesized ")" ""))
            )
      #{
        \tempo \markup {
          \line \general-align #Y #DOWN {
            % 1st column in line
            $label

            % 2nd column in line

            $left-paren

            \score {
              \new Staff \with {

                fontSize = #tempoRelationshipStaffReduce
                \override StaffSymbol.staff-space = #(magstep 
tempoRelationshipStaffReduce)

                % hide the staff lines
                \override StaffSymbol.line-count = #0
                % align horizontally
                \override VerticalAxisGroup.Y-extent = #'(-0.85 . 0)
              }

              {

            } % score end

            $right-paren

      #}))


     \tempoRelationship #"Swing" ##t
     \fixed b' {
       b8 [ b8 ]
     }
     \fixed b' {
       \tuplet 3/2 { b4 b8 }
     }

while they can be described natively in MusicXML:

      
         
           Swing
         
         
           relative-x="26">

             
               eighth

               type="start">

                 3
                 2

                 2
                 eighth
               
             
           
         
       

I’m not at ease enough currently with the Scheme/Lilypond interaction to 
be of any help, unfortunately.

Hello Jacques,

last year I have been working on an export module for lilypond:
https://github.com/jpvoigt/lilypond-export/
This is in an early stage, a proof of concept. I had to put this 
project aside for a while, but it is still on my agenda and hopefully 
it develops further soon.

Hello Joe,

this is touching a subject I have been working on last year. I created 
some kind of proof of concept to export other file formats from 
lilypond. I can export musicXML and Humdrum with some limitations. It 
is based on an infrastructure that exports via format-plugins so it 
should be possible to create one for pd.

If you are interested I can send more informations.

Hello,

When another user inquired about composing without midi playback, i found 
encouragement to ask something from the technical side. Maybe i have some 
healthy curiousity about coding language, which follows:

Is it possible to integrate .ly with other musical coding languages? It 
would be very beneficial to write music that integrates the quick engraving of 
lilpond (other software is too slow for me) with the sound fonts and modulation 
of pure data.

i may have read this being used in rosegarden. however, it took time for me 
to integrate .pd with my soundcard- so i could use some pointers or insurance 
on integrating these two languages!

thank you,
