Virtual Channel Definition Commands
Virtual channel definition commands are a type of control command that
provide methods for defining virtual channels and mapping them to physical
channels. The SoundStructure Studio software will create the virtual channel
definitions based on the input and output selections the designer has chosen.
The syntax described below is what SoundStructure Studio uses to create the
channel definitions.
Channel definition commands support the following three actions.
vcdef
Define a new virtual channel and its physical channel mapping.
vcundef
Delete the definition of a virtual channel.
vcrename
Rename a virtual channel.
The syntax for each of these actions is given in the following sections.
vcdef Action
The vcdef action is a virtual channel definition command that defines a new
virtual channel and its physical channel mapping. Commands with the vcdef
action have the following syntax.
vcdef <label> <vctype> <pctype> <num> [<num> ... ]<term>
Each of the command arguments is described in the following section.
<label>
The <label> argument is a user-defined text argument that defines the name
for the new virtual channel. If a virtual channel or virtual channel group
already exists with the same label, then SoundStructure will respond with an
error message.
<vctype>
The <vctype> argument is a system-defined text argument that defines the
type of virtual channel that will be created. The following values are
supported.
