Thanks Christian. I’m seeing some other problems with C13, too, notably this one: NO rant , just facts Cubase 13 Audio engine Spikes compared to Cubase 12 - #64 by Highly-Controversial
So, I’m holding off on C13 for a few reasons. Obviously, you are quite brilliant at code writing so I’m very sure you will sort this unless of course Steinberg has declared war on PreSonus, maybe a possibility. Thanks, Christian!
