Right now there is a 50/50 chance that MIR will glitch/lag for the first few seconds of any audio export from Nuendo. It sends a completely dry signal initially, then the room sound suddenly kicks in. It does not always do this, but about 50% of the time.
It is not doing this during playback, just export.
I am using MIRpro 24 on Nuendo 10 on Windows 10.
