volta repeat with and without alternative ending

[Gergely K.]

Hi all!

I am engraving an orchestral score, and ran into the following: one staff has volta repeat with alternative ending, but the other staff has no alternate ending.

When I engrave the score for the conductor, strange thing happens (one staff is shorter, that the other)

I also would like to engrave scores for violin and viola, and those notes are in separate files. Viola part should not be aware of the alternative block in violin IMHO.

So, how should I write this piece to be correct? (online version: http://lilybin.com/mpasgy/4)

\version "2.18.2"
\language "deutsch"

violin = \relative c'' {
    \repeat volta 2 { c4 d e f | }
    \alternative {
      { c2 e | }
      { f2 g | }
    }
    c1
}

viola = \relative c' {
    \repeat volta 2 { c4 d e f |
    c2 c }
    c1
}

\score {
  <<
    \new Staff \violin
    \new Staff { \clef alto \viola }
  >>
  \layout { }
}
