Hi, The measure counter currently understands a compressed MM rest as a single measure:
\version "2.23.3" \new Voice \with { \consists Measure_counter_engraver } \compressMMRests { \startMeasureCount c'1 R1*5 c'1 c'1 \stopMeasureCount } This has been registered as an issue in the tracker: https://gitlab.com/lilypond/lilypond/-/issues/6124 I'd like to fix it, but I have no idea how -- I am not a user of the measure counter myself. What should LilyPond print in this case? If you use the measure counter and have an opinion, you are welcome to voice it on the bug page. Thanks, Jean
