Then you should definitely have a look at the last link I sent
(lilypond-html-video); IIRC it uses a Scheme engraver (so no patching
Lily itself) to output svg with additional timing information encoded
as data- attributes for each rhythmic event. Then one can use that to
get a cursor, change CSS attributes on the fly (e.g. noteheads
opacity), switch from one page to the next, etc. It’s still very much
WIP, but you can have a look at the examples (particularly the
vibraphone one) to get an idea.
I’m CCing Mathieu as it’s his project. Mathieu, you can read Matt’s
previous message here:
