The audio and (software) instrument tracks you see in the Arrange window are actually
routed to channel strip objects on the Environment Mixer layer.
The Mixer channel strips and Arrange channel strips are simply remote controls for the
underlying channel strip objects in the Environment Mixer layer. Their inclusion in these
other windows makes your workflow faster and easier.
