If I were you, I would take that midi file made by lilypond and convert it to a midge file. Midge is a GNU text-based midi program. The syntax is unfortunately not similar, but I'm sure that would give you all the control you can stand, and who knows, it may even be a decently efficient way of working. Let us know how it works out. daveA _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org http://lists.gnu.org/mailman/listinfo/bug-lilypond
