Apple Soundtrack Pro 3 - Manual (Page 315)

In the pre-fader case, adjusting the Volume slider on the Music track would have no effect
on the music level in the MusicReverb bus.
Example: Combining Track Signals with Sends and Busses
You can also send the signals from multiple tracks to a single bus, creating “intermediate
submixes.” For example, you could route every dialogue track for a particular actor to a
bus with the actor’s name. You could adjust the volume of all the actor’s dialogue using
the bus volume fader and add an EQ effect that brings out the actor’s voice in the mix.
You could then send (route) the bus to a particular submix.

In the above diagram, tracks 1 and 4 contain dialogue from the actor, Jacob. Each of these
tracks has a send applied to it that taps the signal and routes it to a bus (named “Jacob”).
This bus is effectively an intermediate submix. Now, any effects and fader adjustments
applied to this bus will be available during the final mix as a single channel strip (named
“Jacob”).
