Re: glissando without starting note

[Phil Brooks]

Oops, never mind the above -- I see now that what is missing is the scaling of 
the landing note of the glissando so that the total ends up being 4 beats all 
together:


 {
 %\set Score.skipBars = ##t
 \override Glissando #'style = #'zigzag
 
         \relative c' {
           \clef bass
            \key c \major
            \time 4/4
            f4 f4 f4 f4 
            % glissando thingy 
           {
           \hideNotes
           a,8*1/2
           \noBeam
           \glissando 
           \unHideNotes 
            f''8*1/2-^\fz r8 r4 r2
            }
            f4 f4 f4 f4
            r4 b4 r4 b4
            r4 b4 r4 b4
            \bar "||"
       }
 }

works fine!
