This project is a simple webpage that utilizes the Tonejs library to playback midi files in the style of old video game music, or "chiptune". It does this by interpreting the existing midi information then plays the song back using synthesizers with the simple oscillators which were available in the early videogame consoles: pulse, square, triangle, sawtooth, and noise. The program then interprets the type of oscillator that generally corresponds to the instrument in the midi track, and the result is a reasonable facsimile of what the song would sound like as a "chiptune" song.
