Ben,
It's your use of \markup in this example. If I comment out the \markup
line, the \fill-line line, and the final two lines (the last two } ) then I
get a midi file.
If you want to center the output, there is perhaps a better way. Folks on
this list can help with that (one approach is to set margins explicitly
that move the beginning of the line from the left page edge):
\paper {
top-margin = .5\in
bottom-margin = .5\in
right-margin = .5\in
left-margin = .5\in
}
You might also wish to add tempo for your listening -- this as engraved
uses a default tempo. It is quite slow when playing an Anglican chant like
this one with whole and half notes. You can add \tempo 4 = ## to your
\global section, or in the \midi { } add thus
\midi {
\tempo 4 = 72
}
Regards.
