I'd recommend to use the engraver!
Anyway, if you want to have the dots for rests affected as well, you
need to adress them through the Rest:
\version "2.19.25"
omit-rest-and-dots =
\override Rest.after-line-breaking =
#(lambda (grob)
(ly:grob-set-property! grob 'stencil #f)
(if (not (null? (ly:grob-object grob 'dot)))
(ly:grob-set-property! (ly:grob-object grob 'dot) 'stencil #f)))
centerRests = {
\override Rest.staff-position = #0
}
\new Staff <<
\new Voice
\relative c'' {
\voiceOne
\omit-rest-and-dots
r4 c r d | r2. e4
d2. e4
}
\new Voice
\relative c'' {
\voiceTwo
\centerRests
r4 a8 a8 r4 b8 b8 | r2. c4
c2. a4
}
>>
HTH,
