Hi Peter,
hmmm... I didn't think of this. It's no mystery, it's the
Dot_column_engraver who makes sure that both dots are visible:
%----------------------------------------
\version "2.19.25"
centerRests = {
\override Rest.staff-position = #0
}
\new Staff <<
\new Voice
\relative c'' {
\voiceOne
\centerRests
r c r d | r2. e4
d2. e4
}
\new Voice
\relative c'' {
\voiceTwo
\centerRests
r4 a8 a8 r4 b8 b8 | r2. c4
c2. a4
}
>>
%----------------------------------------
Turning it off completely would result in a mess.
Unfortunately, I don't know a quick way to prevent this. In one of the
voices, you could set dot-count to zero, but this would affect notes and
rests in the same way.
A quick and dirty approach would be to remove the Rest_engraver from the
second voice:
%----------------------------------------
\version "2.19.25"
centerRests = {
\override Rest.staff-position = #0
}
\new Staff <<
\new Voice
\relative c'' {
\voiceOne
\centerRests
r c r d | r2. e4
d2. e4
}
\new Voice \with {\remove "Rest_engraver"}
\relative c'' {
\voiceTwo
%\centerRests
r4 a8 a8 r4 b8 b8 | r2. c4
c2. a4
}
>>
%----------------------------------------
If you look for an automatic solution that detects if both voices have the
same rests, go for the merge-rests-engraver already mentioned by Harm.
AFAIK the most recent version is here:
