output.playNote("C3") doesn't make any ksound #7

I am trying to see if this works on Chrome, and I did following

    WebMidi.enable(function (err) {
      if (err) {
        console.log("WebMidi could not be enabled.", err);
      } else {
        console.log("WebMidi enabled!");
        var mout = WebMidi.outputs[0];
        var mout.playNote("C3");
      }
    });

It doesn't make any sound. Do I need to set volume, instrument, etc?

I don't have any MIDI instrument attached to my computer. I am trying to play sounds just using a browser.

Sorry, I think I should be using soundfont-player instead.. (https://www.npmjs.com/package/soundfont-player)

The playNote() method sends note on commands to the output it is called upon. The output must be a software or hardware MIDI device recognized by your system. It is that device that will play the sound, not WebMidi.js. But, considering your second message, I guess you figured that out! :-)
