For what international computer art subculture did Mark Alan Knight start out his career writing chiptune and module file music for?
Demoscene The demoscene is an international computer art subculture that specializes in producing demos: small, self-contained computer programs that produce audio-visual presentations. The main goal of a demo is to show off programming, artistic, and musical skills.
MOD (file format) MOD is a computer file format used primarily to represent music, and was the first module file format. MOD files use the “.MOD” file extension, except on the Amiga which doesn't rely on filename extensions, instead it reads a file's header to determine filetype. A MOD file contains a set of "instruments" in the form of samples, a number of "patterns" indicating how and when the samples are to be played, and a list of what patterns to play in what order.
