EventEmitter.ANY_EVENT

[mike-shields-dev]

Is there a way to listen to all midi events on a particular port, channel or globally?

I have found this page in the docs: EventEmitter.ANY_EVENT

This sounds like what I want, but how do I use it?

There is currently no way to listen to all MIDI messages globally. You could, however, add a listener for midimessage to all Input or InputChannel objects.

This is how to do it at the Input level:

WebMidi.inputs.forEach(input => {
  input.addListener("midimessage", e => console.log(e));
});

The difference between listening for midimessage and listening for EventEmitter.ANY_EVENT is that the former is only triggered when a MIDI message is received while the latter is triggered by MIDI messages and other events such as opened, closed and disconnected.

Thanks for clearing things up 👍

WebMidi.inputs.forEach(input => {
  input.addListener("midimessage", e => console.log(e));
});

is not working at all for me. I was hope to add a listener for all message. I have to add the listener to everything. (note-on, note-off, cc, etc) I would like to listen to everything and the current code is not working for me. I am using the latest version of NodeJS
