aleatoric squiggles

[James Harkins]

Google let me down on this one -- I'm looking for some advice on notating 
aleatoric materials. The piece is for the Chinese instrument sheng and live 
electronics (computer running SuperCollider). Many of the computer materials 
will start at a specific point in the score, but the exact notes and rhythms 
will be different from performance to performance.

This is close, but seems a little messy. Any ways to clean it up? Also, I think 
it won't work if I want to quote a portion including the glissando line as cue 
notes within another staff (\cueDuring). Would be really nice to have a 
solution that could be cued.

\version "2.14.1"

\score {
  \new Staff \with {
    \override Glissando #'style = #'trill
  } {
    <<
      \new Voice {
        \voiceOne \stemNeutral
        b'2\rest d''8 [ a' d'' e'' ]
        \glissando s2.. 
        \once \override Stem #'transparent = ##t
        \once \override NoteHead #'transparent = ##t
        e''8
      }
      \new Voice {
        \voiceTwo \stemNeutral
        s1
        s2.. b'8\rest
      }
    >>
  }
}

Also, I'd really like to have an arrowhead at the end of the glissando. I can 
find the arrow "sub property" of the line spanner interface, but I'm not clever 
enough to figure out how to use it without an example.

Thanks,
James

PS (Yes, I'm aware of relative mode for pitch entry... it just didn't seem 
worth it to me for this example.)
