I have a solution. Get a second Mac, install Mac OS Mojave. Connect Virus with USB only to this second computer and install the Plugin as usual. Install Logic Pro and make 1 software track with Virus Plugin. Choose main output as AUDIO. On this secondary Mac don't choose Virus as a main Audio interface (select Mac' default in and out), disable in logic all sync options to Virus Ti, select same SampleRate as on the primary Mac. Now, on your primary Mac use MIDI track to send midi notes to Virus as via simple MIDI cable (DIN) and get back Into audio interface MAIN AUDIO OUTs of your Virus.
So, the idea is that with primary computer you use midi and audio of your Virus and on secondary computer you use only Plugin Sound Editing and presets management. Just make sure Secondary computer does not try to send to Virus any kind of sync signals via USB. I have tested and all works fine. See photo.
yeah, i had a similar solution posted here
Virus TI not compatible with MacOS Catalina / Big Sur
with connecting two mac's and midi over network together with audiogridder. this way i could load the GUI on my primary mac.
