Input Bus Configuration
In most cases you do not need to configure a surround format input bus in order to work with surround sound in Nuendo. You can record audio files via standard inputs, and easily route the resulting audio channels to surround outputs at any stage. You can also directly import multi-channel files of a specific surround format to audio tracks of the same format.
However, you must add a surround input bus in the following cases:
You have existing audio material in a specific surround format, and you want to transfer this material to Nuendo as a single, multi-channel file.
You want to make a live recording with a surround setup.
You have prepared surround premixes, for example, stems, that you want to record on a new audio track with a surround configuration.
