MIDIConnectionEvent: MIDIConnectionEvent() constructor

Secure context

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 statechange event.

Syntax

new MIDIConnectionEvent(type)
new MIDIConnectionEvent(type, midiConnectionEventInit)
