A - 18
The <label> argument is a user-defined text argument that specifies the name
of the virtual channel to be renamed. If no virtual channel exists with the given
label, then the SoundStructure device will respond with an error message.
<new-label>
The <new-label> argument is a user-defined text argument that specifies the
new name to assign to the virtual channel. If a virtual channel or virtual
channel group already exists with the same label, then the SoundStructure
device will respond with an error message.
vcrename Acknowledgements
When a virtual channel definition command with the vcrename action is
successfully executed, SoundStructure will send an acknowledgement in the
same format as the command. The acknowledgement will be sent to all
interfaces.
Virtual Channel Group Definition Commands
Virtual channel group definition commands are a type of control command
that provide methods for defining virtual channel groups. Virtual channel
group definition commands support the following six actions.
vcgdef
Define a new virtual channel group.
vcgundef
Delete a virtual channel group definition.
vcgrename
Rename a virtual channel group.
vcgadd
Add a virtual channel member to a virtual channel group.
vcgremove
Remove a virtual channel member from a virtual channel group.
vcglist
List the members of a virtual channel group.
vcgdef Action
The vcgdef Action is a virtual channel group definition command that defines
a new virtual channel group. The action may define an empty virtual channel
group or it may specify one or more virtual channel labels as members of the
virtual channel group. Commands with the vcgdef action have the following
syntax.
