SID music

SID chip

The SID (Sound Interface Device) is a microchip containing a digitally controlled analog synthesizer. Due to its unique sound, its advanced nature (at the time), and the fact that the popular Commodore 64 home computer came equipped with it, the SID chip has attracted a cult-like following, of which I am a part.

A Mind Is Born

It struck me that, at least in theory, organ pipes should generate quite primitive sound waves. If so, how come a church organ doesn't sound like a chip tune, which is also built up from simple waveforms? Well, actually it will, if you remove the church. And if you connect a Commodore 64 home computer to a loudspeaker in a large hall, it will sound like an organ. Read more.
