Changing measure duration creates corrupt score

• May 20, 2015 - 22:16

Under certain circumstances modifying the actual duration of measures in Measure|Properties creates a file that MuseScore reports as corrupted when opening. Perhaps on changing 2 adjacent measures?

See attached image.

Running on MuseScore 2.1.0 unstable (compiled locally today) on Chromebook/Crouton/UbuntuTrusty, however have seen the same behavior on Windows 7 with MS 2.0.0 and earlier versions.

Steps to reproduce:

1) Create new file from template. Template is provided as attachment Church.mscz.
2) Set to 3/4 time.
3) Enter some music as shown in attachment "corrupt.png"
4) At measure 9, stop at note entry mode and change actual duration to 1 / 4
5) Enter note in measure 9
6) At measure 10, stop and change actual duration to 7/4.
7) Continue entering notes into measures 10 and 11.
8) Save file, exit the file, reopen the file, MuseScore reports corruption in measure 10.

Corrupted file is attached as 564c.mscz

I have one correction to what I posted earlier. I didn't actually use the Church.mscz as a template file. I actually used the template for "single instrument" that is provided with MuseScore.

I wouldn't advise to use nightly builds for anything serious. It's better to stick with 2.0.1 really. If you think that the inability to change the actual duration of a measure makes MuseScore useless, maybe there is another way to do what you want? The problem only occurs if the measure is more than 4/4 and starts with a whole rest. Changing the whole measure rest to a quarter note rest is enough to work around the problem.
