Control Events and Mappings

ControlEvent, ShadowControlEvent and ControlMapping all serve as a way to map to controls, but are used in different scenarios.

  • ControlEvent types represent a MIDI event after it has been recognized. They contain info on the value of the event (as a float between 0 and 1) and on the channel of the event (-1 if no channel otherwise 0-15)
  • ControlShadowEvent types are similar to a ControlEvent but are used within the context of plugins so that plugins have access to both the event info and the control shadow associated with the event.
  • ControlMapping types serve as a way to map to a control surface outside the context of events, and as such don't have value or channel parameters.
