Greetings, NR1.2.4 says:
Known issues and warnings Automatically kneed cross-staff beams cannot be used together with hidden staves. Why? The following piece of code works well (and if you uncomment the last line, an ugly #76 collision happens) \layout { \context { \Staff \remove Axis_group_engraver \consists Hara_kiri_engraver %\override Beam #'auto-knee-gap = #'() \override VerticalAxisGroup #'remove-empty = ##t } } \new PianoStaff << \new Staff = "up" s1*24 \new Staff = "dwn" { ais16 ais'16 \change Staff = "up" ais'8 r4 r2 \repeat unfold 23 d'1 } >> -- Cheers, Valentin _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org http://lists.gnu.org/mailman/listinfo/bug-lilypond
