MIDIConnectionEvent.MIDIConnectionEvent()

The MIDIConnectionEvent() constructor creates a new MIDIConnectionEvent object. Typically this constructor is not used as events are created when a new port becomes available, and the object is passed to the MIDIAccess.onstagechange event handler.

new MIDIConnectionEvent(type);
new MIDIConnectionEvent(type, MIDIConnectionEventInit);
