I have this preference ticked in Cubase 9.5.10. But it is not working. Repro:
Add FX channel track to a project.
Click on any other track in the project window. Track is selected there, and you can see it change in the “zones” tab of the mixer, but the track is not actually selected in the mix console. So when I click the channel edit “e” button on my CC121 controller, I get the channel settings for the FX track that I just created opening up, instead of the track I just selected in the project window.
I have to click on another channel in the Mixer window in order for things to work as expected. After that, the project window and mixer windows are in sync.
Am I missing something or is this a bug?
