MIDI in Web Audio

For anyone interested in this topic:
It can be done in JavaScript with Web Audio completely without the use of
plugins, you just have to implement MIDI for yourself (re-invent the wheel
kinda). You just have to do something similar to what I did for the JS GBC
emulator audio. You have to make a javascriptnode for web audio, keep an
audio buffer JS-side, manage the buffer correctly, and create an audio
sample generator. You just have to make your own audio sample generator if
you're gonna use XAudioJS, since I take care of the rest behind the scenes
in the github-based js library.

Seriously, listen closely to http://www.youtube.com/watch?v=Kr_Xob5BoZs and
you will notice it sounds all MIDI-ish. That's because the audio hardware
emulated is basically Nintendo's take on MIDI kind of.
