Hi Harm, probably Simon understands your function better, but what do you gain with it? I tried to use it with \once and it seems like it does not work like this. And a general upward flip of the ties can be achieved more easily with \tieUp
\layout { \context { \Voice \remove "Note_heads_engraver" \consists "Completion_heads_engraver" } } { \tieUp a'\breve } Cheers, Joram _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
