Hello Mats,

IIUC \partial serves to insert an additional amount of time, however in this example we actually need to skip a beat – thus call \partial with a negative duration, which is impossible :-) So you need to insert \set Timing.measureLength = #(ly:make-moment 3/4) before the second bar in your example. Is this documented differently? Else I wouldn’t consider it a bug, rather an inherent limitation.
Please note that \partial has been changed very recently in the 2.19 versions. The documentation for 2.19.25, http://lilypond.org/doc/v2.19/Documentation/notation/displaying-rhythms#index-_005cpartial-1 says that the duration specifies the remaining length of the current measure, which in my example is zero. Note also that my example works fine if I remove the R2*3 line directly below \time 3/4.


Yours, Simon

I tried version 2.19.25 to typeset a piece that changes from 4/4 with an upbeat to 3/4 without an upbeat, in the middle of the piece. The new \partial handling worked for all parts, except a part that started with a multimeasure rest. Here's a small example illustrating the problem. Uncommenting the \bar line makes things slightly better but still wrong.
\version "2.19.25"
\relative c'{
\time 4/4
\partial 4

%\bar "||"
\partial 4*0
\time 3/4
