Apple Logic Express 9 - Manual (Page 768)

By creating a send, you split the channel strip’s signal in two. The channel strip’s main
signal continues its route to the chosen output. The other part of the signal is routed
down a parallel path, via a bus to an aux channel strip. You use the Send level knob to
control the amount of the signal sent via the bus. This is known as parallel routing.
You can choose to route the signal back into the main signal flow at a later point, or you
can choose to output the signal from the aux channel strip.
The following example shows a channel strip routed to multiple aux channel strips via
sends—with reverb, chorus, and delay effects assigned to aux channel strips 1, 2, and 3,
respectively.
On this channel strip, the
effect plug-ins are routed
in parallel, via sends.
The effect plug-ins
(Reverb, Chorus, Delay)
are assigned to aux
channel strips 1, 2, and 3.
The channel strip’s signal is split and routed to three separate effects, one on each aux
channel strip. These three independent signals are then sent back from the respective
aux channel strips and combined into an output stream from the original channel strip.
You can create up to eight sends on each audio, instrument, or aux channel strip. The
behavior of sends is the same across Mixer and Arrange channel strips. For details about
working with send effects, see
Using Send Effects .
