Turrican Soundtrack Anthology, Vol. 2

C64 is a chip‑music style centered on the distinctive SID (MOS 6581/8580) sound chip inside the Commodore 64 home computer (1982). Its hallmarks are three monophonic voices, razor‑edged pulse waves with pulse‑width modulation, bright sawtooths and triangles, a noisy percussion voice, and the iconic multimode analog filter and oscillator sync/ring‑mod tricks. Because the SID has only three voices, classic C64 writing relies on rapid arpeggios to imply chords, fast octave/pulse sweeps for riffs, and clever duty‑cycle and filter automation for expressive “analog” movement. Many pieces were first written for games and crack intros, and later for the demoscene, establishing a self‑contained aesthetic that feels both raw and sophisticated: melodic hooks, propulsive patterns, and timbral wizardry squeezed from 1 MHz and 64 KB.
