Hello all,

I'm typesetting a piece with repeats, for which I'm using the "volta 2"
construction with a first-time and second-time ending. My problem is that I
have a note that is tied from the end of the first ending back to the start
of the "volta" section. This doesn't seem to work with a normal tie, so I'm
trying to use a \repeatTie and attach it to the right-hand side of the
notehead, but I can't figure out how to do it. Here's what I've tried so
far:

\score {
  \relative c' {
  \override RepeatTie #'side-axis = #0
  \override RepeatTie #'direction = #RIGHT

  c2 c2~ \repeat volta 2 { c2 c2 }

\alternative {
{ c2 c2 \repeatTie}
{d2 d2}
              }
              c2 c2 \bar "|." }
}

I just can't get it to work, I would be really grateful if someone could
explain where I'm going wrong.
This is a workaround, but you could use  \laissezVibrer  instead of
using \repeatTie .

Hope that helps (a little).

Cheers,
Xavier

same suggestion as Xavier.
I added a little function to tweak the LaissezVibrerTie, first created
by Enternix from the german forum:
http://www.lilypondforum.de/index.php?topic=1008.msg5637#msg5637
Of course there are other tweaking methods:
via control-points or use the functions of the attached file
containing possibilities to tweak Slur, Tie, PhrasingSlur, RepeatTie
and LaissezVibrerTie (this is a collection of function from the list).

\version "2.14.2"

extendTie =
#(define-music-function (parser location x) (pair?)
#{
   \once  \override LaissezVibrerTie #'stencil = #(lambda (grob)
     (let* ((tie-stencil (laissez-vibrer::print grob))
            (tie-ext (ly:stencil-extent tie-stencil X))
            (tie-length (interval-length tie-ext))
            (new-tie-length (+ tie-length (- (cdr $x)(car $x))))
            (scale-factor (/ new-tie-length tie-length))
            (new-tie-stencil (ly:stencil-scale tie-stencil scale-factor 1))
            (new-tie-ext (ly:stencil-extent new-tie-stencil X))
            (x-corr (- (car tie-ext) (car new-tie-ext)))
            (x-shift (car $x)))

      (ly:stencil-translate-axis
         new-tie-stencil
         (+ x-corr x-shift)
         X)))
#})

%--- test

\score {
  \relative c' {

    c2 c2~
    \repeat volta 2 { c2 c2 }
        \alternative {
        { c2 \extendTie #'(0 . 1.5) c2 \laissezVibrer }
        { d2 d2 }
                     }

    c2 c2 \bar "|."
  }
}


A slightly simpler function to extend a laissezvibrer tie:

\version "2.15.25"

extendLV = #(define-music-function (parser location further) (number?) #{
    \once \override LaissezVibrerTie  #'X-extent = #'(0 . 0)
    \once \override LaissezVibrerTie  #'details #'note-head-gap = #(/ 
further -2)
    \once \override LaissezVibrerTie  #'extra-offset = #(cons (/ 
further 2) 0)
#})

\relative c' {
    c2\laissezVibrer \extendLV #3 c\laissezVibrer
}
