Detailed Description

Extended Host callback interface IComponentHandlerBusActivation for an edit controller.

• [host imp]
• [extends IComponentHandler]
• [released: 3.6.8]
• [optional]

Allows the Plug-in to request the host to activate or deactivate a specific bus, if the host accepts it will call later on IComponent::activateBus (see IComponent::activateBus). Useful especially for Instrument with more than 1 outputs, where the user could request from the Plug-in UI a given output bus activation.
