Child Busses
Child busses allow you to route tracks to particular channels within a surround bus. Creating stereo busses within your surround bus allows you to route stereo tracks directly to a pair of stereo speakers. You can also add child busses in other surround formats with fewer channels than the parent bus.

Once you have created a surround bus, you can add one or several child busses to it by right-clicking the bus and selecting Add Child Bus.
