I have 3 screens. If I have Nuendo-15 running and click outside of Nuendo on the same screen, OR anywhere on either of the other two screens - the project STOPS. This means that it is impossible to use any other software (TotalMix-FX for example) while N15 is running! This does not occur on earlier versions of Nuendo.
My first thought in my tiny, tiny brain goes to “release driver” settings, like does Nuendo still control the driver while you focus other applications? I forget what the setting is called, but it’s probably in the same window as all the other audio interface and buffer and ASIO guard setup stuff.
Check that maybe?
Thank you so much . That is the answer.
At least some of us are still thinking clearly!
