Hi Rutger,
> I cannot make it draw *vertical* lines/arrows, is there anything I overlook?
If the staves are guaranteed to be adjacent, maybe you can hack Arpeggio?
Here's a start:
%%% SNIPPET BEGINS
\version "2.19.62"
arpfix = {
\once \override GrandStaff.Arpeggio.stencil = #ly:arpeggio::brew-chord-bracket
\once \override GrandStaff.Arpeggio.X-offset = #0.5
\once \override GrandStaff.Arpeggio.protrusion = #0
}
upper = { \arpfix c''1\arpeggio }
lower = { f'1\arpeggio }
\score {
\new GrandStaff <<
\new Staff = "upper_staff" \upper
\new Staff = "lower_staff" \lower
>>
\layout {
\context {
\GrandStaff
\override VerticalAxisGroup.staff-staff-spacing.padding = #12
connectArpeggios = ##t
}
}
}
%%% SNIPPET ENDS
Ultimately, it would be great to have a way to connect any two grobs/positions
on a system/page (or even across pages!?), by simply giving ids. I don't know
what has been thought about and/or worked on in that direction (e.g., we now
have nested spanners on the same staff via ids, so maybe there's something in
the works for cross-staff uses).
Hope this helps,
Kieren.
