Mixer not appearing (musescore 4)

• Jun 23, 2023 - 15:16

Mixer stopped appearing, tried so many things don’t know what to do.

So I recently started using Musescore 4 it has worked fine for me for a bit, but the instrument volumes has been a bit wonky, so I usually fix that manually. Today however the mixer has just stopped appearing

I don’t mind writing with the volume being weird but I need to send a sample to a client soon. How do I fix it. It says that the mixer should be visible even though nothing has appeared on screen. Does anybody know anything? I also have had issues with the playback playing this that are not in the score.


Comments

I am disappointed to find this comment staying not responded since June 2023... I have the same issue. It appears that I started to have the same behavior after updating to 4.2.1. I appreciate a suggestion from anybody who have overcome this. Thank you.

I'm gonna make a small bet that the Mixer window has been inadvertently moved outside of the display window, whether up, down, right, or left. In a Windows window this is easy to deal with, but the Mixer window doesn't have the System Menu that Windows windows have in the upper left, which contains the Move command. So I don't know how to fix it.

Only way I can think of would be to perform Help / Revert to factory settings. But I don't know that this will fix the problem (since I'm not having the problem and can't replicate it).

As at Mu 4.4.0 this problem is still not resolved.
When I invoke the Mixer (F10), I still see only a tiny vertical strip overlaid on the Properties panel. It's really tedious to have to drag the width to a more sensible dimension.

OS: Windows 10 Version 2009 or later, Arch.: x86_64,
MuseScore Studio version (64-bit): 4.4.0-242390800, revision: 0fcd11b

"If you open the mixer and resize it, close and reopen it, does it open the way you set it?"

No, the Mixer still just opens as a very narrow vertical stripe. I have to drag the right edge to make the screen visible.

[EDIT]
... and this problem with the Mixer sizing goes way back to 2021 (at least for me).
This thread Mixer panel was as close as I got to understanding what controls the Mixer display:
https://musescore.org/en/node/319781
But still no solution...

Information that might help fixing it:
- are there deterministic steps to reproduce this reliably?
- some people say that it turns out that the mixer is actually appearing, but only super small so that you hardly notice it. Is this true for everyone? Or are there also people who are 100% sure that the mixer is appearing 100% not at all?
- Is "revert factory settings" the only workaround, or does "View > Restore the default layout" also work?

Sorry, I have been away from my desktop for a week.
I must say I find all the installation possibilities confusing, This is a general comment about Ubuntu, not MuseScore !
On this machine I have
- 3.2.3 (apt)
- 3.6.2 unstable (snap)
- 4.2.1 (AppImage)
- 4.4.0 (AppImage)
- 4.4.2 (Flatpak) - the one that has the mixer issues.
- shows Qt 6.7.3. Launching from the shell shows about 5 screens of messages.
4.4.3 Installed just now (2024-10-28) 4.4.3 right now is only available via the AppImage.
- interesting - reports Qt 6.2.4 And lo - the mixer works :)
I hope this helps.

Thanks for your reply! That confirms my thoughts; the FlatPak uses a later version of Qt, that is incompatible with the docking framework that MuseScore uses, and therefore the Mixer won't show up anymore. The good news is that this entire situation will be fixed in MuseScore 4.5. However, it will take a few months still until we release that, so you'll still have to use the AppImage in the meantime.

The AppImage is the official build provided by Muse. The Flatpak, and OS-specific distributions, are maintained by third parties.

About the technical differences: AppImage and Flatpak are two different technologies to achieve approximately the same goal, namely creating a package for an application that should work across all operating systems. AppImage is in a way the least "invasive" option, not requiring the user to install anything, while Flatpak comes with a runtime that the user has to install on their system, but after doing that, FlatPak applications run in a sandboxed environment and are fully managed by the Flatpak tooling.
