You have most likely already have seen the Send and Receive effects listed on the effects context menu in one of the previous exercises. While they are considered effects, they really are a way of routing a group signal to another group for additional processing. This allows us to split and combine multiple signals through the same group or multiple groups for additional effects processing. The following is a diagram showing how this may work and a sample of the type of effects that use multiple signal processing:
Mixer signal routing through return effects groups
The preceding diagram represents the routing we will connect in the next exercise. For simplicity, the Interface mixer group, which is just a placeholder for now, was removed. As the diagram shows, the Direct and Ambient groups will have their signal split to the Master and either a Reverb or Echo return effect. In turn, the Reverb and Echo effect after processing the signal will route...
