Multiband Compressor GUI gone after 2017 update
I updated and imported a project to 2017.
The instances of the multiband compressor (not the obselete one) are appearing without the edit button that lets you open the GUI. So, I can change the parameters in the foldout controls below the plugin name, but without a GUI you can't see what you are doing.
If I instantiate a new Multiband compressor instance, it's fine. But the old one that migrated over is busted.
I just spent over an hour on the phone with Adobe support so that they could tell me in the end that "Adobe doesn't recomment migrating during a project."
