[quote=Wikipedia]The sound chip, SID, had three channels with several different waveforms, ring modulation and filter capabilities. It, too, was very advanced for its time. It was designed by Bob Yannes, who would later co-found synthesizer company Ensoniq. Yannes criticized other contemporary computer sound chips as "primitive, obviously (...) designed by people who knew nothing about music." Often the game music became a hit of its own among C64 users. Well-known composers and programmers of game music on the C64 were Rob Hubbard, Ben Daglish and Martin Galway, among many others.
The SID chip has a distinctive sound which retained a following of devotees. In 1999, Swedish company Elektron produced a SidStation synth module, built around the SID chip, using remaining stocks of the chip. Several bands use these devices in their music.
