Assignment of Parts is not proper working in MS 3.4.1.

• Jan 26, 2020 - 01:00

After the release of MuseScore 3.0, I tried the new features of the parts definition.
My idea was to create one Staff in the score with two voice 1 and 2 (i.e SoA) in order to get on a simple way a compact directors view as a part. At the other hand I expected to create also two parts for Sopran (SoA) und Alt (SoA) which are linked to SoA. My further expectation was, that I can make changes in the two voices of SoA which results also in changes in Sopran (SoA) and Alt (SoA) and vice versa.
For this I create Parts Sopran (SoA) with voice 1 only and Alt (SoA) with voice 2 from Staff SoA.
If there are already notes existing in SoA, they are correct distributed to Sopran (SoA) and Alt (SoA) , but if I add notes they appear in both parts.
A check of the parts definition showed, that both parts, Sopran (SoA) and Alt (SoA), are assigned to voice 1 of SoA... So something went definitly wrong.
Unfortunatly there is no possibility to change or correct this assignment. I can only delete the part, create a new one... and the game starts again...

I would be very greatful, if this feature would work in the next release...
A possiblility to change the assigment of a part and its name would also be nice...
Please find attached the example file test.mscz.

Hi, I checked the latest Version and found still issues...
To explain this I created "Test 1.mscz"
It has one blank staff and I created 4 parts VC 1 to VC 4, each related to one voice of the staff.

This is what I did after loading of "Test 1.mscz":

  1. Goto part VC2
  2. Select all bars
  3. Press Delete

View Main staff we found a break for voice 1 and voice 2 (I didn't like that, so...)

  1. Select all bars
  2. Press Delete

Now we have only one break related to voice 1 per bar

  1. Goto part VC2

We find
1. a different number of bars (really?)
2. a different bar line at the end
3. no bar is selectable
Part VC 1 seems to be ok
I can add notes in the main staff/voice 2, but there is no way to do any edits in the other bars of part VC 2!

The same effect can be reproduced with VC 3 an VC 4.

I guess, things become more clear...

In "Amtsgerichts-Polka.mscz" is a part "Tenorhorn 3" which is corrupted in the same way as in example "Test 1.mscz".
In bar 5 of the main staff "Amtsgerichts-Polka" I add an open repeat (|:) in staff Sopran (Solo)-> MS crashes!!

Sometimes, if i try to past several bars in such a kind of currupted staff MS chrashes also...

Now I delete part "Tenorhorn 3" -> No Problem to add the open repeat as I trid before...

I think there might be several other activities which can be done with such a corrupted staff and may lead to a complete crash!

For me, this is a really severe issue, which I won't expect in a release version!!

There might be issues in concept, coding and testing of all related software parts.
