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.
