Problems with temperament plug-in

• Dec 18, 2023 - 19:01

I started a thread related to this topic a couple of days ago, but it turned into a rabbit hole with no bottom, so I am starting a new thread. I'll spare you all the details of the old one.

I'm using OS: macOS 14.1, Arch.: x86_64, MuseScore version (64-bit): 4.1.1-232071203, revision: e4d1ddf

I'm interested in adjusting the playback of some of my scores to just temperament instead of equal temperament, which is the default temperament for MuseScore playback, as it should be. I learned on this forum that a plug-in included with version 4.0 will do exactly what I want. I just have to enable it.

In my list of plug-ins, I see "Modal Tuning" and "Modal Temperaments." Is it one of these? Both crash MuseScore instantly, every time. It's possible I'm doing something wrong. If so, I don't know what it is.

I found a plug-in called tuning.qmi. It looks like it's intended for MuseScore 3.x, but someone on the previous thread seemed to say it should also work in 4.x. It's not clear if it is similar to one of the plug-ins that ship with 4.x. I installed it and enabled it. It also crashes MuseScore instantly, every time.

Someone on the previous thread suggested I open the tuning.qmi plug-in with a text editor and replace Qt.quit() with just quit(). I tried that. The string Qt.quit does not appear in the code for the plug-in.

Where do I go from here?

Thanks in advance.

Neither. It is called "Tuning", pls see screenshot

If there's no such option, you just discover a bug "Tuning plugin not shown inside Home: Plugins". You could help other macOS users by reporting at , include link to this post and

  • a screenshot of the plugins window on your machine
  • a screenshot of your /Applications/MuseScore (to reveal files in the app bundle, right-click on MuseScore and choose "Show package contents")
  • a screenshot of your ~/Library/Application Support/MuseScore/MuseScore 4/plugins.
  • a screenshot of your ~/Documents/MuseScore4/Plugins

There's also another possible bug "Modal Tuning and Modal Temperaments plugin crash ms4.1.1 macOS", but reporting it may be futile as the ms4 plugin system itself is work in progress.
