MIDIConnectionEvent.port

The port read-only property of the MIDIConnectionEvent interface returns the port that has been disconnected or connected.

Syntax

let port = MIDIConnectionEvent.port;

Value

A MIDIPort object.

Examples

The Navigator.requestMIDIAccess() method returns a promise that resolves with a MIDIAccess object. When a port changes state, a MIDIConnectionEvent is passed to MIDIAccess.onstatechange. Information about the port can then be printed to the console.

navigator.requestMIDIAccess()
  .then(function(access) {

     access.onstatechange = function(e) {
       console.log(e.port.name, e.port.manufacturer, e.port.state);
     };
  });
