All,
I am involved in some choral
recording projects where we are
having the singers sing from
projected slides. To aid in timing,
pitch, etc., we have it set up where
they have headphones feeding them the
MIDI of the song being recorded as
they sing. All of this is synchonored
through the recording software, with
the slides being pre-rendered to a
video file.
Right now, the music slides are being
created in Finale (cringe), the MIDI
is being manually input into the
recording software because we've had
issues with Finale's MIDI being
accurate on tempo changes, and I am
using Apple Keynote to render the
slides to video using manual timings.
I would like to use Lilypond to
render the individual slides and the
MIDI, then use ffmpeg and some other
things to programmatically render the
video itself. The issue is that in
order to do that, I need accurate
timing information on slide changes.
Which gets to my question/request. Is
there a way, when Lilypond is
running, for it to output some sort
of auxiliary file with some kind of
tick/time code information about each
page? In other words, what is the
time index of the first note on a
given slide/page? With this, I can
work with scripting tools to work
backwards from each time code to
generate the still images for the
transitions from slide to slide.
Thanks,
Carl
