New issue 4205 by [email protected]: Part combiner shifts or omits rests
https://code.google.com/p/lilypond/issues/detail?id=4205
The part combiner is sloppy about analyzing rests. In some cases the
output is merely ugly, but in others it actually omits rests, producing
output that doesn't make musical sense. (I have a patch in the works
already, but I wanted to show the problem first.)
\version "2.19.15"
% rests of different durations beginning simultaneously, followed by
% unisilence
\score {
\partcombine
\relative f' { r4 r2 r8 r8 | r1 }
\relative f' { r8 r8 r2 r4 | r1 }
}
% rests of different durations beginning simultaneously, followed by
% solo then a2.
\score {
\partcombine
\relative f' { r4 f2. | r8 f e2. }
\relative f' { r8 d f2. | r4 e2. }
}
% mmrest and rest of different durations beginning simultaneously
\score {
\partcombine
\relative f' { r4 f2. | R1 }
\relative f' { R1 | r4 d2. } % missing r4 is misleading
}
