Omnivocal, Mac, Cubase 15

Hi. I’m on Mac. I install Omnivocal, it loads (yes I load it as instrument, it’s not THAT problem) I agree to everything, but the “Activate Omnivocal” virtual switch, though lit up, doesn’t do anything. Again, it lights up as if making the app available, but nothing happens when I press on it or hit enter or return. I’ve deleted, reinstalled, updated everything, reinstalled again. Steinberg washes their hands of the whole thing, blames it on Yamaha, and I upgraded to 15 only to get this feature. Getting a bit frustrated.

Any thoughts? M4 Max, Sequoia 15.7.3 Cubase 15 (latest 02/11/2026)
