Measure numbers differ between score and parts

• Mar 28, 2021 - 20:27

I discovered that if you create parts, and then add measures with irregular beats in the score and set them to be excluded from the measure count, the parts do not recognize that the extra measures are excluded. You have set this option for all of the excluded measures in every part.

Here you go. Steps to reproduce plus an attached example:

1) Create a score and parts.
2) In the score, add three measures somewhere in the middle, for a cadenza.
3) Also in the score, make each of the added three measures have an irregular number of beats, and also exclude them from the measure count. Write in your cadenza. Also, make the barlines invisible, and the rests in the other parts invisible.
4) View the parts. In this case the score has 32 numbered measures, while all the parts have 35.

Note: I could not reproduce this if the measures had the regular number of beats, in this case 4/4. It only happens when the measures excluded from the count have an irregular number of beats, in this case 63/8, 18/2 and 34/4.

When you delete a time signature, this involves rewriting the measure, so it will indeed clear any properties that might have been set for the original measure. But this thread is about parts, and your score doesn't have any parts, so I suspect you are talking about something else entirely. Can you be more specific about the problem you are seeing? This score is in an odd state to be sure, no reason to have the second 4/4 after the pickup. If you just want to fix that, delete that. The pickup measure before the delete 4/4 won 't be affected.

Deleting the 4/4/ is a totally different act than replacing it by 2/4. The latter leaves the measures at 2 beats long, since it already was two beats long. Deleting the initial time signature forces MuseScore re-evaluate the measure completely. It's not something you should normally ever do - every piece should start with a time signature,. Even writing non-metric music, there should be a time signature but made invisible, just so museScore understands how to structure its measures internally. Deleting the initial time signature converts it from whatever it was to 4/4, because it has to assume something. Hence, as I said, it gets rewritten. Actually, you whole score would be rewritten if there wasn't another 4/4/ immediately following.
