xxx CHIPTUNE xxx A chiptune, also known as chip music or 8-bit music, is synthesized electronic music which is 1) made for PSG sound chips (real or emulated) used in vintage computers, consoles, and arcade machines or 2) tracker format music which intentionally sounds similar to old PSG chip music or 3) music that combines PSG sounds and modern electronica/EDM music styles. In the early 1980s, personal computers became less expensive and more accessible than they had previously been. This led to a proliferation of outdated personal computers and game consoles that had been abandoned by consumers as they upgraded to newer machines. They were in low demand by consumers as a whole, and not difficult to find, making them a highly accessible and affordable method of creating sound or art. While it has been a mostly underground genre, chiptune has had periods of moderate popularity in the 1980s and 21st century, and has influenced the development of electronic dance music xxx The terms "chip music" and "chiptune" refer to music made by the sound chips found within early gaming systems and microcomputers. A waveform generator is a fundamental module in a sound synthesis system. A waveform generator usually produces a basic geometrical waveform with a fixed or variable timbre and variable pitch. Common waveform generator configurations usually included two or three simple waveforms and often a single pseudo-random-noise generator (PRNG). Available waveforms often included pulse wave (whose timbre can be varied by modifying the duty cycle), square wave (a symmetrical pulse wave producing only odd overtones), triangle wave (which has a fixed timbre containing only odd harmonics, but is softer than a square wave), and sawtooth wave (which has a bright raspy timbre and contains odd and even harmonics). Two notable examples of systems employing this technology comprise the Game Boy and the Commodore 64. The Game Boy uses two pulse channels (switchable between 12.5%, 25%, 50% and 75% wave duty cycle), a channel for 4-bit PCM playback, and a pseudo-random-noise generator. The Commodore 64, however, used the MOS Technology SID chip which offered 3 channels, each switchable between pulse, saw-tooth, triangle, and noise. Unlike the Game Boy, the pulse channels on the Commodore 64 allowed full control over wave duty cycles. The SID was a very technically advanced chip, offering many other features including ring modulation and adjustable resonance filters. xxx Source: Wikipedia xxx

xxx DRUM MACHINE xxx A drum machine is an electronic musical instrument designed to imitate the sound of drums, cymbals, other percussion instruments, and often basslines. Drum machines are most commonly associated with electronic music genres such as house music, but are also used in many other genres. They are also used when session drummers are not available or if the production cannot afford the cost of a professional drummer. In the 2010s, most modern drum machines are sequencers with a sample playback (rompler) or synthesizer component that specializes in the reproduction of drum timbres. Though features vary from model to model, many modern drum machines can also produce unique sounds, and allow the user to compose unique drum beats and patterns. xxx Source: Wikipedia xxx
