So, are you just estimating the position of each note, based on nothing
more than elapsed time? You aren't, for example, parsing the PDF file
to try to determine the actual locations of the notes?
I'm not convinced that such an approach can be made to work. The rules
that make Lilypond output so beautiful intentionally move notes away
from their strictly time-based position. Further, notes are sometimes
spread out to fill out a staff that would otherwise be too short.
My apologies if I have misunderstood, but I'd like to know more about
what you're doing.
