Ah, now I get the connection to your other posts on the Frescobaldi list ;-)

A solution to this is probably not that far-fetched, but in order to get
there you have to either get to a clear understanding of what you want
to achieve or - if you actually have that - communicate it clearly so we
all know where we want to get. I think you have a very valid use case
here that would be good to support.
I *think* what you will want is to have the score examples accompanied
by *links* (in whatever graphical form, as plain text links or as fancy
graphic buttons). These links should point to either the MIDI files
created by LilyPond, *or* to audio files that have been generated from
these MIDI files in advance. I can think of no other suitable concept of
having a "document" play back the score examples. If I'm missing
anything please correct me.
Here's what has to be done to achieve that goal. Please create an issue
at https://github.com/jperon/lyluatex/issues and copy as much
information as possible/useful from this thread. I would not want to
continue discussion here because it really isn't a "luatex" issue but
relates to lyluatex and LilyPond directly:
* lyluatex has to make LilyPond also produce the MIDI files beside the
This has not been implemented yet, but should be a minor thing to do
(and as said, I find this a valuable use case)
* lyluatex will then (automatically) produce poth a
<unique-hash-name>.pdf and a <same-unique-hash-name>.midi file in
the cache directory
* With the 'raw-pdf' option lyluatex will return that calculated base
name instead of directly including the score as an image.
* From there you can create a macro that will include the image and
create a link to the midi file.
This can be done with standard LaTeX means
* Or you can add a hook in between to call another external program to
generate the corresponding audio file and link to that.
This would probably be (much) easier to program in Lua, since Lua is

This last assumption is on spot.
And no, we're not going to remove that file.
In the development repository we author the manual in a Markdown file,
and it is compiled through Pandoc. But the make rule for producing the
CTAN upload the Markdown file is compiled to the corresponding .tex
file. So that lyluatex.tex file is an official part of the CTAN package
(and I would assume that it is also copied *somewhere* into your texlive

You should also look into the the lyluatex.sty file since that also
loads a number of packages. But AFAIK there are no *special* packages
needed that aren't available in regular TeX Live (I just don't know what
happens if you haven't installed texlive-full).

From what I can see in your communications I'm not 100% confident you
have set up LilyPond properly already.
lyluatex does its work by calling LilyPond as an external command, so
that has to be a) installed and b) found by lyluatex.
If you don't have a working environment I suggest downloading the
current development version from http://lilypond.org/development.html
(they are not at all "unstable" in the case of LilyPond) and installing
it (I don't know what OS you are having).
If you are on a UNIX OS and can run "lilypond --version" after the
installation everything should be fine, but if you have to specify any
other command line you have to provide this to lyluatex through the
If you still have errors after that please report with more details - we
have tried to make the error handling as informative as possible - but
do so on the lyluatex issue tracker, not here.

Having literally spent years with this topic I can't give you too much
hope about this :-(
