Package Summary Overview Summary

### class:ControllerEventListener [NONE]
- 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. See Also: `MidiChannel.controlChange(int, int)`

### method:controlChange(javax.sound.midi.ShortMessage) [NONE]
- #### controlChange
      void controlChange(ShortMessage event)
Invoked when a `Sequencer` has encountered and processed a control-change event of interest to this listener. The event passed in is a `ShortMessage` whose first data byte indicates the controller number and whose second data byte is the value to which the controller was set. Parameters: `event` - the control-change event that the sequencer encountered in the sequence it is processing See Also: `Sequencer.addControllerEventListener(ControllerEventListener, int[])` , `MidiChannel.controlChange(int, int)` , `ShortMessage.getData1()`, `ShortMessage.getData2()`
