OK, thanks, papi61.
Here is the “Listen Bus” behavior in Cubase Control Room I like:
When the “L” button is clicked on a track in Cubase while the project is playing, the track continues to play at normal volume, but all other tracks are lowered by “X” dB, where “X” is able to be entered (e.g., 20 dB).
This is kind of like an “incomplete mute” button - allows the track to be heard in the context of the full project playing, but with emphasis on the track in question because the other tracks are lowered in volume.
Thanks!
