Having stopped using Cubase for a few years in favor of Dorico, I am starting back into using it. I'm immediately encountering a problem where I set a VI Pro instance to use MIRx, but on starting the transport it reverts to bypassing the reverb and playing a dry signal. Going back in and changing it back doesn't help, it just happens again. I'm puzzled as to why. I don't believe there's any sort of CC command or setting that does this.
This happens across all instances in the Cubase project, and all are instrument track that directly access VI Pro. There is no MIR Pro running.
