Hi Mojca, Christopher, Hraban, Wolfgang, the new lilypond module don't build new lilypond pdf files when I change the tex input file. In the log i get: system : module lilypond loaded (c:/contextminimal/texmf-local/tex/context/third/lilypond/t-lilypond.texMTXrun | file './lilytemp/lily1-lilypond-1.tmp' is unchanged MTXrun | file './lilytemp/lily1-lilypond-1.eps' is unchanged loading : LilyPond module My testfile lily1.tex adopted and slightly changed from Vyatcheslav \usemodule[lilypond] \starttext There are some notes \lower 8.2pt\hbox{\lilypond[fragment=true]{\relative c' {c d e f}}} embedded in this line. \stoptext Perhaps this is a feature? Greetings Lutz
