Since my KK Slider video showcasing a fan-made remix of Enter Sandman did shockingly well on YouTube, I thought I might as well try my own hand at a remix. So, I remixed a MIDI of Enter Sandman to best imitate what the song would sound like on a Commodore 64's SID chip.

The Commodore 64's SID (Sound Interface Device) chip had 3 audio channels, which could play four different waveforms: Square, triangle, sawtooth and noise. However, the SID chip could have all of its voices set to any of those waveforms rapidly on the fly to give the illusion of 9 or 10.

Since MIDI doesn't have noise or triangle waves, I muted the percussion and set the bass line to sawtooth waves (a pretty common use for sawtooth in SID music) and set the other guitars to square waves. This totals four real channels, which could have been imitated by the SID chip by rapidly swapping waveforms on the fly such that there's the illusion of a fourth channel.
