I recently upgraded to Cubase 10.5 from 10.
I was able to open the current project I was working on (started in 10) but after adding a couple of plugins, the system beach balled and I had to force quit. I relaunched and tried adding the same plugin and it opened, but then the Audio Performance meter peaked out. All audio stops and main out meters flash intermittently. What’s weird is that I can still navigate Cubase and add inserts, but nothing plays or moves or sends an audio signal. If I quit and relaunch, the project is fine, until I try and add any plugin. Same result with any VST instrument, FX, VST2 or 3, any channel, any manufacturer… it doesn’t work. Cubase is completely unusable.
What’s even more odd, is now this problem has infected my version 10 and it’s now exhibiting the exact same issues so I can’t use that either now.
