Hi all. The size and position of the bracket in the second score are not computed correctly. Apparently the bracket is not scaled; if you use, say, 10 instead of 17 it becomes clearer.
\version "2.19.84" music = \new PianoStaff \with { connectArpeggios = ##t \override Arpeggio.stencil = #ly:arpeggio::brew-chord-bracket } << \new Staff { \clef "treble" c'4\arpeggio } \new Staff { \clef "bass" b,4\arpeggio } >> \score { \music } \score { \music \layout { #(layout-set-staff-size 17) } } Is there any workaround? Should this be added to the tracker? Best wishes. Davide
