I forgot to thank you.  It works great.

I'm using a Laissez Vibrer tie on a chord.  It works fine, but I would like to change the shape.  \shape works fine but for only one tie.  How do I shape both ties?

As with the ties in a TieColumn, \shape won't work for l.v. ties in a LaissezVibrerTieColumn.  One solution here is to adapt \shapeTieColumn (in openlilylib and on the -user list).

Try this:

\version "2.19.15"

shapeLVTieColumn =

#(define-music-function (parser location all-offsets) (list?)

   #{

     \override LaissezVibrerTieColumn.before-line-breaking =

     #(lambda (grob)

        (let ((ties (ly:grob-array->list (ly:grob-object grob 'ties))))

          (for-each

           (lambda (tie offsets)

             (set! (ly:grob-property tie 'control-points)

                   (map

                    (lambda (x y) (coord-translate x y))

                    (ly:tie::calc-control-points tie)

                    offsets))) 

           ties all-offsets)))

   #})

\language "english"

\relative c, {

  \time 3/4

  \key a \major

  \clef bass

  \shapeLVTieColumn #' (

                       ((1 . 0) (2 . 0) (3 . 0) (17 . 0))

                       ((1 . 0) (2 . 0) (3 . 0) (4 . 0))

                       )

  <a a'>2. \laissezVibrer |

}

%%% -- End
