Is it possible to copy and paste a chanel configuration (ie. all the sends)?

It highly depends on your prior experience with software development.

Anyway, here is a version that will work on BigSur (11.0) and later on both Intel and Apple Silicon (M1, M2): https://x42-plugins.com/tmp/x42-matrixmixer-24x24-lv2-macOS-v0.4.3-1.zip

unzip and copy to $HOME/Library/Audio/Plug-Ins/LV2/

The plugin is not notarized/signed by Apple, so depending on your system’s gatekeeper setting you may have to

xattr -rd com.apple.quarantine ~/Library/Audio/Plug-Ins/LV2/matrixmixer-i24o24.lv2/*dylib

Thanks a lot Robin - just one last problem (I hope): I believe my gatekeeper settings are still default, so must bash the code. However, Terminal points out that there is “no such file: /Users/leo/Library/Audio/Plug-Ins/LV2/matrixmixer-i24o24.lv2/*dylib”
I have installed the plugin system wide in Macintosh HD/Library/Audio/Plug-Ins/LV2/matrixmixer-i24o24.lv2/
I’m so green, I tried changing the message for Terminal, but seem to be messing it up.
Please can you write the correct bash code for me🙄

Resolved: OK, I managed. All working. Awesome!

late reply, but for future reference:

In that case remove the ~/ and run it as admin with sudo:

sudo xattr -rd com.apple.quarantine /Library/Audio/Plug-Ins/LV2/matrixmixer-i24o24.lv2/*dylib
