`Receiver` | `getReceiver()` Obtains the current receiver to which this transmitter will deliver MIDI messages.
`void` | `setReceiver(Receiver receiver)` Sets the receiver to which this transmitter will deliver MIDI messages.

Method Detail

### setReceiver

  Parameters:
    `receiver` - the desired receiver.

### getReceiver

    public Receiver getReceiver()
