Huh, this doesn't seem to handle commas or semicolons at all. I can't immediately see why, since string.toUpperCase() maps "," to "," and ";" to ";", as it should. And switching input to

"uyvyu,pl,ynuuupl,kmk,,uyvuyvyu,pl,ynuuupl,kmk,,uyvppp;[[;plp;;;pl,kmk,ynuu,,,kmmml;pl,,kuu,lp;[,lp;l,"

completely breaks it about half way through.

Anyway, cool hack!

That's because the keydown event uses keyCode instead of charCode, and the two don't always match. Try typing Shift+U and then '[' on this page to see what I mean: http://unixpapa.com/js/testkey.html.

Since KeyboardJS is already loaded via requirejs, we can require it and then use it to get the keyCode for each character in the for loop.

    var KeyboardJS = require('lib/keyboard');

    [...]

    for (var i = 0; i < input.length; ++i) {
      var code = KeyboardJS.key.code(input.charAt(i));
      if (code) {
        soundArray.push(code);
      } else {
        soundArray.push(32);
      }
    }
