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. -- Tim Roberts, [email protected] Providenza & Boekelheide, Inc.
