BusInfo: This is the structure used with getBusInfo, informing the host about what is a specific given bus. \n See also: IComponent::getBusInfo
Routing Information: When the Plug-in supports multiple I/O buses, a host may want to know how the buses are related. The relation of an event-input-channel to an audio-output-bus in particular is of interest to the host (in order to relate MIDI-tracks to audio-channels) \n See also: IComponent::getRoutingInfo, \ref vst3Routing
