ConTeXts writes out all the LilyPond pieces as "myfile-lilypond- #.tmp", sequential numbered. Then it should run LilyPond and epstopdf on the snippets, but runs them always only on no.1
I.e. the counter doesn't behave like it should. Why?
I think, these are the regarding code snippets (sorry, can't think of a minimal example for I don't understand the code by Christopher):
