Interface ControllerEventListener

All Superinterfaces:

EventListener

public interface ControllerEventListener
extends EventListener

The ControllerEventListener interface should be implemented by classes whose instances need to be notified when a Sequencer has processed a requested type of MIDI control-change event. To register a ControllerEventListener object to receive such notifications, invoke the addControllerEventListener method of Sequencer, specifying the types of MIDI controllers about which you are interested in getting control-change notifications.
