Hey Guy. I triple-checked this and, there seems to be an issue with the UVIWorkstation VST3 version. If you have the plain VST version also installed, try that. I tried with both breath controller and expression pedal. Nothing gets through. I havent seen this since I use Falcon mostly. I am going to have to check the Falcon VST3 now.
No, I am looking at more VST3s and I am sensing this is a bigger problem, so stay away from VST3 until MG3 if you can. I’ve tried a few SWAM and Arturia plugins with the same result, and when searching this forum I found this poor contributor having reported, but with no response, unfortunately.
