Sure. Suppose you have connected this audio coming from the global rackspace to a gain control plugin in your local rackspace. Connect a widget to the mute parameter of this plugin to mute and unmute the signal.
Give this widget the name (called “handle”) “Mute” and declare it in the local rackspace script:
Var
Mute : widget
We want the script to set the widget to mute when we “leave” the rackspace so we use the callback “on deactivate”.
On deactivate
SetWidgetValue(Mute,1)
End
That’s it. You need to do this for every rackspace that uses your global audio.
