Korg Poly-800
The Korg Poly-800 is a synthesizer released by Korg in 1983. Its initial list price of $795 made it the first fully programmable synthesizer that sold for less than $1000. It featured a 49 key non-velocity sensitive keyboard, two buttons for data entry, and a joystick controller, which could modulate the DCO pitch or the VCF. Though the Poly-800 had MIDI, it did not feature MIDI MIDI#System Exclusive messages, SysEx functionality (except EX800 - the expander-version; or by modding the Poly800 with additionally selectable EX-firmware-ROM), and patches had to be backed up to cassette tape. It had 8-voice polyphony (paraphony) with one Digitally controlled oscillator, DCO per voice. It could be switched into double mode which stacks two DCOs for a fuller sound, but reduces the polyphony to 4 voices. It featured one analog resonant low-pass VCF with 24 dB/oct which was shared for all voices. Like a monophonic synthesizer, the filter was switchable between single or multiple m ...

Korg
, founded as Keio Electronic Laboratories, is a Japanese multinational corporation that manufactures electronic musical instruments, audio processors and guitar pedals, recording equipment, and electronic tuners. Under the Vox brand name, they also manufacture guitar amplifiers and electric guitars. History Korg was founded in 1962 in Tokyo by Tsutomu Kato and Tadashi Osanai as ''Keio Gijutsu Kenkyujo Ltd.''. It later became because its offices were located near the Keio train line in Tokyo and Keio can be formed by combining the first letters of Kato and Osanai. Before founding the company, Kato ran a nightclub. Osanai, a Tokyo University graduate and noted accordionist, regularly performed at Kato's club accompanied by a Wurlitzer Sideman rhythm machine. Dissatisfied with the rhythm machine, Osanai convinced Kato to finance his efforts to build a better one.Julian Colbeck, Keyfax Omnibus Edition, MixBooks, 1996, p. 52.

Polyphony
Polyphony ( ) is a type of musical texture consisting of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice, monophony, or a texture with one dominant melodic voice accompanied by chords, homophony. Within the context of the Western musical tradition, the term ''polyphony'' is usually used to refer to music of the late Middle Ages and Renaissance. Baroque forms such as fugue, which might be called polyphonic, are usually described instead as contrapuntal. Also, as opposed to the ''species'' terminology of counterpoint, polyphony was generally either "pitch-against-pitch" / "point-against-point" or "sustained-pitch" in one part with melismas of varying lengths in another. In all cases the conception was probably what Margaret Bent (1999) calls "dyadic counterpoint", with each part being written generally against one other part, with all parts modified if needed in the end. This point-against-point conception is opposed to " ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Frequency Modulation Synthesis
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The frequency of an oscillator is altered "in accordance with the amplitude of a modulating signal". FM synthesis can create both harmonic and inharmonic sounds. To synthesize harmonic sounds, the modulating signal must have a harmonic relationship to the original carrier signal. As the amount of frequency modulation increases, the sound grows progressively complex. Through the use of modulators with frequencies that are non-integer multiples of the carrier signal (i.e. inharmonic), inharmonic bell-like and percussive spectra can be created. FM synthesis using analog oscillators may result in pitch instability. However, FM synthesis can also be implemented digitally, which is more stable and became standard practice. Digital FM synthesis (implemented as phase modulation) was the basis of several musical instru ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Voltage-controlled Filter
A voltage-controlled filter (VCF) is an electronic filter whose operating characteristics (primarily cutoff frequency) can be set by an input control voltage. Voltage controlled filters are widely used in synthesizers. A music synthesizer VCF allows its cutoff frequency, and sometimes its Q factor (resonance at the cutoff frequency), to be continuously varied. The filter outputs often include a lowpass response, and sometimes highpass, bandpass or notch responses. Some musical VCFs offer a variable ''slope'' which determines the rate of attenuation outside the bandpass, often at 6 dB/octave, 12 dB/octave, 18 dB/octave or 24 dB/octave (one-, two-, three- and four-pole filters, respectively). In modular analog synthesizers, VCFs receive signal input from signal sources, including oscillators and noise, or the output of other processors. By varying the cutoff frequency, the filter passes or attenuates partials of the input signal. In some popular electroni ...

Music Sequencer
A music sequencer (or audio sequencer or simply sequencer) is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically CV/Gate, MIDI, or Open Sound Control (OSC), and possibly audio and automation data for DAWs and plug-ins. On WhatIs.com of TechTarget (whatis.techtarget.com), an author seems to define a term "Sequencer" as an abbreviation of "MIDI sequencer". * Note: an example of section title containing "''Audio Sequencer''" Overview Modern sequencers The advent of Musical Instrument Digital Interface (MIDI) and the Atari ST home computer in the 1980s gave programmers the opportunity to design software that could more easily record and play back sequences of notes played or programmed by a musician. This software also improved on the quality of the earlier sequencers which tended to be mechanical sounding and were only able to play back notes of exactly equal duration. Sof ...

Vox Continental
The Vox Continental is a transistorised combo organ that was manufactured between 1962 and 1971 by the British musical equipment manufacturer Vox. It was designed for touring musicians and as an alternative to the heavy Hammond organ. It supports drawbars in a similar manner to the Hammond, and has distinctive reverse-coloured keys. The sound is generated by a series of oscillators, using a frequency divider to span multiple octaves. The first Continentals were produced at Vox's manufacturing plant in Dartford, England; after arranging a deal with the Thomas Organ Company, later models were produced in the US and Italy. The most popular model was the single-manual Continental, but other models were produced, such as the budget Vox Jaguar, various dual-manual organs, and the experimental Guitar Organ and Voxmobile, based on the Vox Continental's internals. The Continental became a popular instrument in the 1960s and 1970s, especially with garage and later new wave bands, and ...

Low-frequency Oscillation
Low-frequency oscillation (LFO) is an electronic frequency that is usually below 20 Hz and creates a rhythmic pulse or sweep. This is used to modulate musical equipment such as synthesizers to create audio effects such as vibrato, tremolo and phasing. History Low-frequency oscillation was introduced with modular synthesizers of the 1960s, such as the Moog synthesizer. Often the LFO effect was accidental, as there were myriad configurations that could be "patched" by the synth operator. LFOs have since appeared in some form on almost every synthesizer. More recently other electronic musical instruments, such as samplers and software synthesizers, have included LFOs to increase their sound alteration capabilities. Overview The primary oscillator circuits of a synthesizer are used to create the audio signals. An LFO is a secondary oscillator that operates at a significantly lower frequency (hence its name), typically below 20 Hz - that is, below the range of human heari ...

Paraphony
Paraphony is a term which has three distinct meanings in the field of music. In musical theory Paraphony is a term used in musical vernacular to refer to consonances which rely upon intervals of fifths and fourths. This terminology can be traced to ancient Greece and sources such as Theon of Smyrna. In electronic music Completely unrelated to the above sense, a synthesizer is called paraphonic if it can play multiple pitches at once, but those pitches share part of their electronic signal paths. For example, the Roland RS-202 string machine could play several dozen pitches at once, but only with a single shared volume envelope, requiring the collective chord to swell and diminish as a single cohesive whole. Similarly, the Korg Poly-800 had 8 oscillators and could produce 8 voices, but had just one filter circuit shared by all of them. Other examples include the Roland VP-330 vocoder and the Moog Sub 37.

Synthesizer
A synthesizer (also spelled synthesiser) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI. Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II Sound Synthesizer, RCA Mark II, which was controlled with Punched card, punch cards and used hundreds of vacuum tubes.
