Examples

In the following example the name of each MIDIInput is printed to the console. Then, onmidimessage events are listened for on all input ports. When a message is received the MIDIMessageEvent.data property is printed to the console.

inputs.forEach((input) => {
  console.log(input.name); /* inherited property from MIDIPort */
  input.onmidimessage = function(message) {
    console.log(message.data);
  }
})
