\partial Problem

[Hajo Dezelski]

Hello,

today is not my day. Since several hours I try to solve a problem in a
score, but I don't find my fault or the right syntax. I always get the
warning:

test3.ly:18:26: Warnung: Taktüberprüfung gescheitert bei: -1/16
                s2 a4. s8
                          | % 1

The condensed score (music makes no sense ;-) :

---------------
\version "2.13.10"

melodyOne=  \relative d' {
        \repeat volta 2 {
                \partial 16
                d16 |  % 0 Auftakt
                f4  d4  a4. r16 s16 | % 1
        }
    \repeat volta 2 {
        \partial 16
        e'16 | % 0 Auftakt
                f4 e4  d4. r16 s16 | % 2
    }
}
melodyTwo=  \relative d' {
        \repeat volta 2 {
                s16 | % 0 Auftakt
                s2 a4. s8 | % 1
        }
    \repeat volta 2 {
                s16 | % 0 Auftakt
                s2 d4. s8 | % 2
    }
}
melody = << \melodyOne \\ \melodyTwo >>

\score {
        \context Staff <<  { \clef treble \key d \minor \time 4/4  \melody  } >>
        \layout { }
}

------------------

Could someone give me a hint?

Thanks in advance

Hajo
