Chords do not appear at the right position

[Niklas Uhrberg]

Using the input file below, the chords do not appear at the correct positions
relative to the melody.

Both chords and melody span four bars of music and for example the second chord
(C ) appears at the fourth beat of the first bar but it is supposed to appear at
the first beat of the second bar.

Thanks!
