Hello, Someone (perhaps Valentin) gave me a snippet to create a context containing only top texts such as rehearsal marks, tempo texts and metronome marks. I use it for my work very well. All my scores are frenched scores. %% Layout to produce MarkLine context %% to place rehearsal marks and texts above full score \layout { \context { \type "Engraver_group" \name "MarkLine" \consists "Output_property_engraver" \consists "Axis_group_engraver" \consists "Mark_engraver" \consists "Metronome_mark_engraver" \consists "Script_engraver" \consists "Text_engraver" \consists "Text_spanner_engraver" \consists "Font_size_engraver" \override VerticalAxisGroup #'minimum-Y-extent = #'(-2 . 2 ) \override TextSpanner #'breakable = ##t } \context { \Score \accepts "MarkLine" } \context { \StaffGroup \accepts "MarkLine" } \context { \PianoStaff \accepts "MarkLine" } \context { \GrandStaff \accepts "MarkLine" } \context { \ChoirStaff \accepts "MarkLine" } } (of course, you must remove rehearsal and metronome engravers out of Score) Now I meet a new problem: at bar 201 of my piece, only harp is used for a cadenza. It begins a new line, so all other instruments have gone. I put the mark line to both top and before the first violin. Unfortunately, it doesn't disappear when strings are not here. I'd like it to: 1. Keep alive when the instruments below it are used; 2. But disappear when the below staves are hidden. Two results will happen if this is not solved: a) When instruments before the first violin are all silent, there will be two parallel mark lines, since the one before first violin has lower outside-staff property; b) When strings are silent, the second mark line is still here, which I think is not good. Could anyone help me? Regards Haipeng
