Subtractive Synthesis
Subtractive synthesis is a method of sound synthesis in which Harmonic_series_(music)#Partial.2C_harmonic.2C_fundamental.2C_inharmonicity.2C_and_overtone, overtones of an audio signal are attenuated by a audio filter, filter to alter the timbre of the sound. Overview Subtractive synthesis relies on source sounds that have overtones, such as Sine wave, non-sinusoidal waveforms like Square wave (waveform), square and triangle wave, triangle waves, or white noise, white and pink noise. These overtones are then Modulation, modulated to alter the source sound. This modulation can happen in a wide variety of ways, such as Voltage-controlled filter, voltage-controlled or low-pass filter, low-pass filters. The technology developed in experimental electronic studios which were primarily focused on telecommunications and military applications. Early examples include Bell Labs' Voder (1937–8). Composers began applying the concept of subtractive synthesis beyond the recording studio in conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Synthesis
A synthesizer (also synthesiser or synth) 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, which was controlled with punch cards and used hundreds of vacuum tubes. The Moog synthesizer, developed by Robert Moog and first sold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikrophonie (Stockhausen)
''Mikrophonie'' is the title given by Karlheinz Stockhausen to two of his compositions, written in 1964 and 1965, in which "normally inaudible vibrations ... are made audible by an active process of sound detection (comparable to the auscultation of a body by a physician); the microphone is used actively as a musical instrument, in contrast to its former passive function of reproducing sounds as faithfully as possible". Together with Stockhausen's immediately preceding work ''Mixtur'', for five orchestra groups, four sine-wave generators, four ring modulators, they form a triptych of Live electronic music, live-electronic works, where electronic transformations are accomplished during the performance (as opposed to studio-produced electronic music on tape). Similar to a group of three of the composer's works from the previous decade, ''Gruppen'', ''Zeitmaße'', and ''Gesang der Jünglinge'', there is one work each for orchestral, chamber, and vocal forces.

Wiley (publisher)
John Wiley & Sons, Inc., commonly known as Wiley (), is an American multinational publishing company that focuses on academic publishing and instructional materials. The company was founded in 1807 and produces books, journals, and encyclopedias, in print and electronically, as well as online products and services, training materials, and educational materials for undergraduate, graduate, and continuing education students. History The company was established in 1807 when Charles Wiley opened a print shop in Manhattan. The company was the publisher of 19th century American literary figures like James Fenimore Cooper, Washington Irving, Herman Melville, and Edgar Allan Poe, as well as of legal, religious, and other non-fiction titles. The firm took its current name in 1865. Wiley later shifted its focus to scientific, technical, and engineering subject areas, abandoning its literary interests. Wiley's son John (born in Flatbush, New York, October 4, 1808; died in East ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korg MS-20
The Korg MS-20 is a patchable semi-modular monophonic analog synthesizer which Korg released in 1978 and which was in production until 1983. It was part of Korg's MS series of instruments, which also included the single oscillator MS-10, the keyboardless MS-50 module, the SQ-10 sequencer, and the VC-10 Vocoder. Additional devices included the MS-01 Foot Controller, MS-02 Interface, MS-03 Signal Processor, and MS-04 Modulation Pedal. Although the MS-20 follows a conventional subtractive synthesis architecture with oscillators, filter, and VCA, its patch panel allows some rerouting of both audio and modulation signals, alongside an external signal processor. This flexibility led to its resurgence during the analog revival of the late 1990s. In response to a revived interest in monophonic analog synthesizers, Korg has reintroduced the MS-20 in various formats: the scaled-down MS-20 Mini, unassembled desktop and full-sized versions, and, in 2020, a full-sized reissue known as the ...

Oberheim OB-1
The Oberheim OB-1 was a Monophonic synthesizer, monophonic analog synthesizer introduced by Oberheim Electronics in late 1977. With the ability to store and recall up to 8 instances of its sound settings, it was the first completely programmable synthesizer, and the first of Oberheim's OB-series of synthesizers. Development Oberheim's OB-series was developed as a replacement for the previous generation of Oberheim Polyphonic Synthesizer, Oberheim SEM-based instruments and intended to be used for live performance. Building on the technology developed for their Polyphonic Synthesizer Programmer, Oberheim designed the OB-1 with the ability to store and recall up to 8 instances of its sound settings, making it the world's first completely programmable synthesizer. It originally sold for $1,895. A slightly updated version, the Oberheim OB-1a, was introduced in 1979 that features the grey color scheme of its polyphonic sibling, the Oberheim OB-X, OB-X. Specification The OB-1 features t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARP 2600
The ARP 2600 is a subtractive synthesizer first produced by ARP Instruments in 1971. History Developed by a design team headed by ARP namesake Alan R. Pearlman and engineer Dennis Colin, the ARP 2600 was introduced in 1971 as the successor to ARP's first instrument, the ARP 2500, at a retail price of US$2600. Unlike fully modular synthesizers, which often required modules to be purchased individually and wired by the user, the 2600 is semi-modular with a fixed selection of basic synthesizer components internally pre-wired. It sports clear text labels and front panel screen printed graphics indicating the function of different sections of controls, and the signal flow between them. The 2600 is thus ideal for musicians new to synthesis, due to its ability to be operated without patch cords, while still offering greater flexibility to sound designers who are comfortable using them. On its initial release it was heavily marketed to high schools and universities. Features and arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minimoog
The Minimoog is an analog synthesizer first manufactured by Moog Music between 1970 and 1981. Designed as a more affordable, portable version of the modular Moog synthesizer, it was the first synthesizer sold in retail stores. It was first popular with progressive rock and jazz musicians and found wide use in disco, pop, rock and electronic music. Production of the Minimoog stopped in the early 1980s after the sale of Moog Music. In 2002, founder Robert Moog regained the rights to the Moog brand, bought the company, and released an updated version of the Minimoog, the Minimoog Voyager. In 2016 and in 2022, Moog Music released another new version of the original Minimoog. Development In the 1960s, RA Moog Co manufactured Moog synthesizers, which helped bring electronic sounds to music but remained inaccessible to ordinary people. These modular synthesizers were difficult to use and required users to connect components manually with patch cables to create sounds. They w ...

EMS VCS 3
The VCS 3 (or VCS3; an initialism for ''Voltage Controlled Studio, version #3'') is a portable analogue synthesizer with a flexible modular voice architecture introduced by Electronic Music Studios (EMS) in 1969. EMS released the product under various names. Logos printed at the console's front left (see photos) say "V.C.S. 3" on the most widely sold version; "The Putney (VCS 3)" on the earlier version; and "The Synthi (VCS 3) II" on the later version "Synthi VCS 3 II". History The VCS 3 was created in 1969 by Peter Zinovieff's EMS company. The electronics were designed largely by David Cockerell, and its distinctive appearance was the work of electronic composer Tristram Cary. It was one of the first ''portable'' commercially available synthesizers, in the sense that it was housed entirely in a small wooden case, unlike synths from American manufacturers such as Moog Music, ARP and Buchla, which had large cabinets and could take up entire rooms. ...

Buchla Electronic Musical Instruments
Buchla Electronic Musical Instruments (BEMI) was a manufacturer of synthesizers and unique MIDI controllers. The origins of the company could be found in Buchla & Associates, created in 1963 by synthesizer pioneer Don Buchla of Berkeley, California. In 2012 the original company led by Don Buchla was acquired by a group of Australian investors trading as Audio Supermarket Pty. Ltd. The company was renamed Buchla Electronic Musical Instruments as part of the acquisition. In 2018 the assets of BEMI were acquired by a new entity, Buchla U.S.A., and the company continues under new ownership. Company origin Buchla's first modular electronic music system was the result of a San Francisco Tape Music Center commission by composers Ramon Sender and Morton Subotnick in 1963, who later allotted $500 from a Rockefeller Foundation grant to Buchla in 1964. Subotnick envisioned a voltage-controlled instrument that would allow musicians and composers to create sounds suited to their own specificat ...

Novachord
The Novachord is the world's first commercial polyphonic synthesizer, polyphonic synthesizer. Incorporating many circuit and control elements found in modern synthesizers, and using subtractive synthesis to generate tones, it was designed by John M. Hanert, Laurens Hammond and C. N. Williams, and was manufactured by the Hammond organ, Hammond company. Only 1,069 Novachords were built over a period from 1939 to 1942. It was one of very few electronic products released by Hammond that was not intended to emulate the sound of an organ. History of production While production of the Novachord began in November 1938, it was first heard at the 1939 New York World's Fair. The Novachord Orchestra of Ferde Grofé performed daily at the Ford stand with four Novachords and a Hammond organ, Hammond Organ. The first instrument was delivered to President Franklin D. Roosevelt on January 30, 1940 as a birthday present. The Novachord was not well-suited to the technique of organists or pianists ...

Trautonium
The Trautonium is an electronic synthesizer invented in 1930 by Friedrich Trautwein in Berlin at the Musikhochschule's music and radio lab, the Rundfunkversuchstelle. Soon afterward Oskar Sala joined him, continuing development until Sala's death in 2002. Description Instead of a keyboard, its manual is made of a resistor wire over a metal plate, which is pressed to create a sound. Expressive playing was possible with this wire by gliding on it, creating vibrato with small movements. Volume was controlled by the pressure of the finger on the wire and board. The first Trautoniums were marketed by Telefunken from 1933 until 1935 (200 were made). The sounds were at first produced by neon-tube relaxation oscillators Example of a similar early neon keyboard invention by Winston E. Kock (later, thyratrons, then transistors), which produced sawtooth-like waveforms. The pitch was determined by the position at which the performer pressed the resistive wire into contact with ...

Analog Synthesizer
An analog synthesizer () is a synthesizer that uses Analogue electronics, analog circuits and analog signals to generate sound electronically. The earliest analog synthesizers in the 1920s and 1930s, such as the Trautonium, were built with a variety of vacuum tube, vacuum-tube (thermionic valve) and electro-mechanical technologies. After the 1960s, analog synthesizers were built using operational amplifier (op-amp) integrated circuits, and used potentiometers (pots, or variable resistors) to adjust the sound parameters. Analog synthesizers also use low-pass filters and high-pass filters to modify the sound. While 1960s-era analog synthesizers such as the Moog synthesizer, Moog used a number of independent electronic modules connected by patch cables, later analog synthesizers such as the Minimoog integrated them into single units, eliminating patch cords in favour of integrated signal routing systems. History 1900–1920 The earliest mention of a "synthetic harmoniser" using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
