Harm, I would call this a known issue, and there are other features that similarly interfere with \partCombine. If it ever seemed to work in the past, it depended on the specifics of the music. \partCombine is a two-pass feature. In your example, the first pass does not know that you will be removing tagged music, so the information it records is inconsistent with the music when it comes time for the second pass. If you want to use \partCombine with filtering, unfolded repeats, or other transformations, you must transform first so that the music is in its final form before the first pass, something like this: \partCombine { \removeWithTag … \one } { \removeWithTag … \two } Merry Christmas, — Dan _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
