Pasting a partial measure of a single voice to measure without that voice corrupts score.

• Sep 3, 2021 - 22:41

Using revision:
OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 3.6.2.548021803, revision: 3224f34
Frequency: always reproducible (IMO, so easy, no example file necessary)

Case: Copy one or more notes of a single voice, other than voice 1, and paste into one or more measures in which the pasted voice is not present.
Result: If the copied notes do not end on a measure boundary (the length of the copied music is not a multiple of a measure), the pasted voice is not extended (padded) to fill the last measure. If the score is saved and reloaded, MuseScore complains about the measure.

To reproduce the issue:
1) Copy part of a measure including voice 2, 3, or 4 (not including voice 1!),
2) Select a measure that only has voice 1 and paste that which was copied.
Carefully examine the voice that was pasted. The pasted voice was not padded with rests to fill the measure.

I first noticed this copying a Drumset part (Voice 2 is used for feet and a little more) where I copied a partial measure and only got the rests for voice 1.

Workarounds:
* Create the additional voice before pasting (Tools->Voice->...).
* Use the Voice tools to switch the partial voice to Voice 1. I've had this work, but I also had a case where I was unable to switch the voice and had to undo the paste and use the other method.

Maybe not so easy after all. Unless I missed something. Totally possible.

In a blank measure of my score I placed four quarter notes using voice 2.
I copied beats 2 and 3.
Pasted into two different measures with only voice 1. One measure on beat 2 and the other measure on beat 3.
indeed no rests generated.
Saved and closed the score.
Reopened without problem.

I didn't use a percussion staff, but did I miss something?

Thank you for your response. I stand corrected about serious problems with the score.

I first noticed this problem in an earlier release (possibly 3, though maybe 3.5). At that time, I couldn't add to the incomplete voice and, after saving, MuseScore complained when I tried to restore. Seeing the incomplete voice and not finding the problem in either the forum or issues, I wrongly assumed the problem still existed.

Since seeing your response, I retested and found that I am now able to add new material to the second voice in that measure even though the rests are missing. This now becomes a minor annoyance instead of an issue. The appearance is almost the same as if the rest(s) were made not visible (but seeing or not seeing not-visible has no effect), and replacing them with notes requires extra effort.

Again, thank you.
