Re: aleatoric squiggles

[address@hidden]

Karim Barkati <address@hidden> is currently typesetting a score not unlike this 
for viola & electronics.  I'm ccing him to this e-mail: his approach also uses 
glissandi and looks really nice.

For the arrow:
\relative c' {\override Glissando #'bound-details #'right #'arrow = ##t c1 
\glissando s1 c1 }

For the cuing, if the glissando is always gonna be flat, try:

\relative c' {
\override Glissando #'bound-details #'right #'padding = #0
\override Glissando #'bound-details #'left #'padding = #0
f4 \glissando
\override Voice . NoteHead #'stencil = #(ly:make-stencil '() '(0 . 0) '(0 . 0))
\override Voice . Stem #'stencil = ##f
\repeat unfold 22 { f4 \glissando }
\revert Voice . NoteHead #'stencil
f4
}

Karim does something like this - it allows you to break the glissando at any 
given beat and still have it in cued voices.

Cheers,
MS
