Re: Issue 1609 in lilypond: unpredictable change of voicing

Comment #2 on issue 1609 by address@hidden: unpredictable change of  
voicing
http://code.google.com/p/lilypond/issues/detail?id=1609

The troublesome regtest, midi/partcombine.ly, sets two voices in  
\partcombine, which produces four voices in the midi output, each on their  
own track :
Solo (either soloI or soloII)
 Unison
 Divisi One
 Divisi Two
and then midi2ly reads these four voices and correctly places them in one  
Staff.

The only problem is that the midi2ly output requires something that current  
LilyPond does not typeset consistently: three rests simultaneous with notes  
of different duration.

However, the silent voices automatically produced by partcombine should not  
have rests; they should have skips, which is midi2ly option --skip.  It  
seems the regtest needs
-options=""
+options="--skip"
