Violas (section) associated with certain notes and a tempo marking crashes the program at opening/or launching playback

[cadiz2]

Issue type

Crash or freeze

Bug description

It's all summed up in the title.

Steps to reproduce

1. Create a three-measure score for Violas (section)
2. Write some notes and rhythms, the ones you can see on the GIF and in the attached .mscz test file: Violas test.zip, and not others apparently...
3. Save/close
4. Reopen: with no tempo marking, it doesn't crash (as in the attached GIF) when loading audio samples. On the other hand, if you add a tempo marking, and start playback, it crashes (as seen on the GIF).

Alternatively (other scenario): if the tempo marking is already present on the score (as on the score attached to the OP on the forum - see link in "Additional context", or on the same minimal test file: Violas test tempo.zip, the file shuts down at opening (more precisely: when audio samples are being loaded)

Screenshots/Screen recordings

MuseScore Version

4.3

Regression

I don't know

Operating system

Windows 10

Additional context

• Change instrument to Viola (solo) solves the issue.

• I cannot reproduce eg with Cellos (section). And by changed the pitch of notes, the problem seems to evaporate (and if I remove the third measure too...) In short, it's hard to pinpoint a precise trigger. It's a combination of certain things (certain notes, a tempo marking, and the Violas instrument) that trip up MuseScore.

And as the OP pointed out in his last message on the forum, with a tempo marking of 79 (for example), no crash at opening. So, what happens? 🙄 See: tempo 79.zip

Just to clarify, is this only when using MuseSounds? Or Soundfont/VST too?

[cadiz2]

I was using Muse Sounds. Well, I'm confused, I can't reproduce right now. I've just checked the Muse Sampler version, it's 0.6.3. From memory, I had version 0.6.1 when I downloaded version 4.3 several days ago. I don't know what version I had three days ago. Perhaps an update to Muse Sampler solved the problem?

Perhaps an update to Muse Sampler solved the problem?

Yeah! We had some crashes related to Muse Sampler and they were fixed with a new version (0.6.3)

Please reopen if happens again
