Re: Two arpeggio lines (up and down) next to each other

Hi Jackens,

Here’s a start:

%%%  SNIPPET BEGINS
% LilyBin

updownArpMarkup =
\markup \concat {
  \override #'(baseline-skip . 1) \column {
    \musicglyph #"scripts.arpeggio.arrow.1"
    \musicglyph #"scripts.arpeggio"
    \musicglyph #"scripts.arpeggio"
    \musicglyph #"scripts.arpeggio"
  }
  \hspace #0.625
  \lower #0.25 \override #'(baseline-skip . 1) \column {
    \musicglyph #"scripts.arpeggio"
    \musicglyph #"scripts.arpeggio"
    \musicglyph #"scripts.arpeggio"
    \musicglyph #"scripts.arpeggio.arrow.M1"
  }
}
updownArp =
        -\tweak Arpeggio.stencil #ly:text-interface::print
        -\tweak Arpeggio.text \markup \updownArpMarkup
        -\tweak Arpeggio.direction #1
        -\tweak Arpeggio.padding #0.625
        -\arpeggio


\score
{
        {
                <c' e' g' c''>1-\arpeggio
                <c' e' g' c''>1-\updownArp
                <g e' c'' g''>1-\updownArp
        }
}
%%%  SNIPPET ENDS

The problem (shown in the third example) is that it doesn’t stretch to match 
the chord height, like a normal arpeggio does. I don’t have time — and maybe 
not even the skill — to do this The Right Way™ right now, but hopefully Someone 
Else™ will take it to the goal line.

Cheers,
Kieren.
