Re: partial measure with independent time signatures

[Mats Bengtsson]

The reason for your problems is that the command \partial 8 is 
equivalent to
\set Score.measurePosition = #(ly:make-moment -1 8)
which does the setting on the Score level. The solution is to make the 
corresponding
setting in the "Timing" context (which is just an alias for the context 
where the
Timing_translator currently lives:

\version "2.12.1"

\layout {
\context {
\Score
\remove "Timing_translator"
\remove "Default_bar_line_engraver"
}
\context {
\Staff
\consists "Timing_translator"
\consists "Default_bar_line_engraver"
}
}
% Now each staff has its own time signature.
\relative c' <<
\new Staff {
\time 2/4
\set Timing.measurePosition = #(ly:make-moment -1 8)
%\partial 8*1
d8 | d4 f8 a
}
\new Staff {
\time 2/2
\set Timing.measurePosition = #(ly:make-moment -1 4)
%\partial 4*1
a,4 | d4. e8 f4 g
}
>>
