Simon, do you know why I might have received this email? It does not seem that anything in the ticket was updated. (I also received a similar email about #4550.) — Dan

The part-combiner walks > through the score as following: > 1) In the first measure, only mI is playing, so it starts a solo (mII has a > multi-measure rest) and uses only the music events from mI > 2) In the second measure both voices have a multi-measure rest, the solo of > mI has ended. As mII has a multi-measure rest already going on, the > part-combiner needs to take the multi-measure rest from mI (the part-combiner > is not able to split up a multi-measure rest!) > 3) In the third measure, mII has a rest, so the first quarter is still > detected as unisilence (thus the rest from mI is still used). Now, as there > is already a whole measure rest going on, lilypond ignores the following > notes. > > Note that there are some other bugs in the part-combiner that can be seen > with this example: > > -) If one replaces the [r4] with a b4 in measure 3, then the notes are > displayed (marked as "Solo II", but the whole-measure rest from mI is > displayed, too. > -) If one adds a measure "c1" to both voices, the "[r4]" in mI is wrongly > printed as a full-measure rest (rests in unisilence are taken from the second > voice, unless voice one had a solo ending before the rest, like in the > original example) > -) If one adds any note after the "[r1]*2" in mI, then the notes are > correctly printed. > > As Xavier already mentioned, there is a workaround to force the partcombiner > to use a particular combining strategy. (Also note that the first quarter > eight rest in the third measure of your original example is printed as if > there were two voices present... Also in this case you need to tell the > part-combiner that the rest should be a solo, too.
