Thank you, this goes a little beyond mere curiosity in fact - I just
spent a few days looking at this problem and was just about to abandon
it. Can I ask for an overview of the flow you use?
I can see a
score.ly
containing the regular LilyPond score and
live-score.ily
I guess to make the LilyPond executable do things on encountering notes,
rests etc
and I see a python script which seems (I don't speak python!) to take a
file
events.txt
and output a file
score.svg
Is the rest (js) a matter of confabulating the svg from LilyPond with
that score.svg file and an audio file to make the webpage?
