Hi Eric,
I have tried to implement them with a new Voice with custom noteheads and no stems. [...] Was I on the right track treating them as notes in a voice?
If they're always played at the same time -- i.e., as chords -- then why not just write them as chords, and \tweak the notehead shape of the appropriate element?
Hope this helps! Kieren. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
