Hi Ming, This is a known issue: <http://www.lilypond.org/doc/v2.18/Documentation/notation/special-rhythmic-concerns#grace-notes> You need to add a grace note skip to the other staff context(s) in order to synchronize.
Hope this helps! Kieren. _______________________ Kieren MacMillan, composer www: <http://www.kierenmacmillan.info> email: i...@kierenmacmillan.info _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
