Through version 5.5x, I could have Nuendo play even while some other program’s window was in front of it… so I could roll video and dialog while looking through a music library, or use SoundMiner’s searching by just clicking the SM window (and having a monitor path through a Nuendo channel set to Input Monitor).
Now the audio goes away, and the transport stops, when you select some other app. This is a bug, removing useful functionality from a previous version. It couldn’t possibly be a feature.
