MIDIMessageEvent: MIDIMessageEvent() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The MIDIMessageEvent() constructor creates a new MIDIMessageEvent object. Typically this constructor is not used as events are created when a MIDIInput finishes receiving one or more MIDI messages.
