Wiring The Devices

7 - 2
One of the most important steps when working with SoundStructure devices
is to ensure the physical cabling (for instance what's plugged into input 3) of
the system exactly matches how the virtual channels are defined.
Virtual channels, as introduced in Chapter 3, provide an abstraction layer
around the physical input and output channels. Virtual channels make it pos-
sible to refer to, and control, signals by their virtual channel names rather than
by the physical input and output numbers. Virtual channels make the system
more portable as control system code that is developed can be reused by using
the same virtual channel names across different installations - regardless of
how the system is physically cabled.
As a system is being designed with SoundStructure Studio, the SoundStruc-
ture Studio software defines the virtual channels and then uses the virtual
channels with all subsequent operations on those channels.
The first step in verifying the wiring is to view the wiring page within Sound-
Structure Studio and expand the inputs and outputs as shown in the following
figure.
The wiring page shows the definitions of the virtual channels along with the
underlying physical channels. In this figure table microphones 1 through 8 are
