Audio Bus Architecture

The audio signals of zones, layers, programs, and slots are managed via audio busses. You can load insert effects into any of the audio busses, for example, to process the audio of a single layer or an entire program.

Slots have one dedicated bus.

Programs can have one or more audio busses that mix the audio signals from the layers and zones that they contain.

Layers do not have to have an audio bus. However, you can create audio busses for layers, for example, to create a submix of the zones that they contain.

AUX busses allow you to use send effects with zones, layers, programs, and slots. Send effects can be shared between zones, layers, programs, and slots, but you can also add local AUX busses to use send effects for individual zones or layers.

Zones do not have an audio bus of their own. Instead, their outputs are automatically routed to the next available audio bus. Any zone, audio bus, and AUX bus can be assigned freely to one of the stereo outputs or to the surround output of the plug-in. For example, a zone output can be routed to an output bus, omitting any audio busses and their effects in between.
