Knute, Don't know about a bug, yet this is a start (not too pretty),
%%% Start %%% \version "2.19.84" \language "english" \relative { \key fs \minor \time 3/8 << { gs'8 \once \override NoteColumn.force-hshift = #2.2 \once \override Accidental.X-extent = #'(1 . 0) \once \override Accidental.extra-offset = #'(3 . 0) fss gs } \\ { fs fs fs } >> } %%% End %%% Mark -----Original Message----- From: lilypond-user [mailto:lilypond-user-bounces+carsonmark=ca.rr....@gnu.org] On Behalf Of Knute Snortum Sent: Wednesday, February 19, 2020 11:01 AM To: lilypond-user@gnu.org Subject: Merging note heads with different pitches. Bug? Consider this snippet: %%% Start %%% \version "2.19.84" \language "english" \relative { \key fs \minor \time 3/8 << { gs'8 fss gs } \\ { fs fs fs } >> } %%% End %%% Why does the fss note head get merged with the fs? Is this a bug? If not, how do I stop it from happening? --- Knute Snortum (via Gmail)
