Interface ControllerEventListener

All Superinterfaces:
EventListener sample code for java.util.EventListener definition code for java.util.EventListener

public interface ControllerEventListener
extends EventListener sample code for java.util.EventListener definition code for java.util.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 sample code for javax.sound.midi.Sequencer.addControllerEventListener(javax.sound.midi.ControllerEventListener, int[]) definition code for javax.sound.midi.Sequencer.addControllerEventListener(javax.sound.midi.ControllerEventListener, int[]) method of Sequencer, specifying the types of MIDI controllers about which you are interested in getting control-change notifications.

          Invoked when a Sequencer has encountered and processed a control-change event of interest to this listener.
 

Method Detail

controlChange sample code for javax.sound.midi.ControllerEventListener.controlChange(javax.sound.midi.ShortMessage) definition code for javax.sound.midi.ControllerEventListener.controlChange(javax.sound.midi.ShortMessage)

void controlChange(ShortMessage sample code for javax.sound.midi.ShortMessage definition code for javax.sound.midi.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
