The Sound Behind Chiptune

The SID, or Sound Interface Device, was the sound chip of the Commodore 64, launched in 1982. The original MOS 6581 chip was designed by Bob Yannes, who later co-founded the synthesizer maker Ensoniq. It worked much like a small synthesizer on a chip.

The SID had three voices, each able to play triangle, sawtooth, pulse or noise waveforms, and noise made hissing drum sounds. A built-in analog filter shaped tone, making it unusual among home computer sound chips. With only three voices, composers faked chords using rapid arpeggios, flicking through notes very fast.

Composers such as Rob Hubbard and Martin Galway created famous game soundtracks. A later revision, the 8580, sounds noticeably different, especially its filter. The SID helped shape chiptune music, and musicians still collect the chip and use it in modern instruments.
