No. Thank you for that suggestion. On http://lilypond.org/doc/v2.19/Documentation/usage/command_002dline-usage only the 'scm backend is described, and it may provide what I need. However, this would require me to compile the score twice and parse the resulting file. Probably it would be more efficient if I could create an engraver (?) that collects just the required data and produces the appropriate output file along with the score. What is the 'socket backend?
