A Cue configuration bus map is used when the same bus destination is used for multiple Cues.
You can create a Cue configuration bus map by selecting [GlobalSettings]>[BusMap] > [BusMapforCue] in the project tree.
For more information on assigning a bus map to a Cue, refer to Configuring a Effect Plugin Via the Bus Send of the Cue.
Right-click on the BusMapforCue folder and select [Create BusMap] from the context menu.
