The same has happened to me. I am running Sonoma 14.3, but it does not appear that I need Rosetta because it is a Universal plugin (I’ve tried it already). I can run EZMIX stand Alone, well it pops up (I cannot use it in CUBASE). I’ve re-installed EZMIX a couple of times, but I can’t seem to add it to my effects in cubase. When I go to my VST management and click on Scan, it scans and it tells me there are (0) vST to add.
