Synthesiser
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, which was controlled with punch cards and used hundreds of vacuum tubes. The Moog synthesizer, developed by Robert Moog and first sold in 1964, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Moog
Robert Arthur Moog ( ; May 23, 1934 – August 21, 2005) was an American engineer and electronic music pioneer. He was the founder of the synthesizer manufacturer Moog Music and the inventor of the first commercial synthesizer, the Moog synthesizer, which debuted in 1964. In 1970, Moog released a more portable model, the Minimoog, described as the most famous and influential synthesizer in history. Among Moog's honors are a Technical Grammy Award, received in 2002, and an induction into the National Inventors Hall of Fame. By 1963, Moog had been designing and selling theremins for several years, while working towards a PhD in engineering physics at Cornell University. He developed his synthesizer in response to demand for more practical and affordable electronic music equipment, guided by suggestions and requests from composers. Moog's principal innovation was the voltage-controlled oscillator, which uses voltage to control pitch. He also introduced fundamental synthesizer conce ...

Moog Synthesizer
The Moog synthesizer is a modular synthesizer developed by the American engineer Robert Moog. Moog debuted it in 1964, and Moog's company R. A. Moog Co. (later known as Moog Music) produced numerous models from 1965 to 1981, and again from 2014. It was the first commercial synthesizer, and is credited with creating the analog synthesizer as it is known today. The Moog synthesizer consists of separate modules which create and shape sounds, which are connected via patch cords. Modules include voltage-controlled oscillators, amplifiers, filters, envelope generators, noise generators, ring modulators, triggers, and mixers. The synthesizer can be played using controllers including keyboards, joysticks, pedals, and ribbon controllers, or controlled with sequencers. Its oscillators can produce waveforms of different timbres, which can be modulated and filtered to shape their sounds (subtractive synthesis). By 1963, Robert Moog had been designing and selling theremins for several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha DX7
The Yamaha DX7 is a synthesizer manufactured by the Yamaha Corporation from 1983 to 1989. It was the first successful digital synthesizer and is one of the best-selling synthesizers in history, selling more than 200,000 units. In the early 1980s, the synthesizer market was dominated by analog synthesizers. Frequency modulation synthesis, FM synthesis, a means of generating sounds via frequency modulation, was developed by John Chowning at Stanford University, California. FM synthesis created brighter, "glassier" sounds, and could better imitate acoustic sounds such as brass. Yamaha licensed the technology to create the DX7, combining it with very-large-scale integration chips to lower manufacturing costs. With its complex menus and lack of conventional controls, few learned to program the DX7 in depth. However, its preset sounds became staples of 1980s pop music, used by artists including A-ha, Kenny Loggins, Kool & the Gang, Whitney Houston, Chicago (band), Chicago, Phil Collin ...

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 ...

RCA Mark II Sound Synthesizer
The RCA Mark II Sound Synthesizer (nicknamed ''Victor'') was the first programmable electronic synthesizer and the flagship piece of equipment at the Columbia-Princeton Electronic Music Center. Designed by Herbert Belar and Harry Olson at RCA, with contributions by Vladimir Ussachevsky and Peter Mauzey, it was installed at Columbia University in 1957. Consisting of a room-sized array of interconnected sound synthesis components, the Mark II gave the user more flexibility and had twice the number of tone oscillators as its predecessor, the Mark I. The synthesizer was funded by a large grant from the Rockefeller Foundation. Earlier 20th century electronic instruments such as the Telharmonium or the theremin were manually operated. The RCA combined diverse electronic sound generation with a music sequencer, which proved a huge attraction to composers of the day, who were growing weary of creating electronic works by splicing together individual sounds recorded on sections of magnetic ...

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] |
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 were a ...

Modular Synthesizer
Modular synthesizers are synthesizers composed of separate modules for different functions. The modules can be connected together by the user to create a patch. The outputs from the modules may include audio signals, analog control voltages, or digital signals for logic or timing conditions. Typical modules are voltage-controlled oscillators, voltage-controlled filters, voltage-controlled amplifiers and envelope generators. History The first modular synthesizer was developed by German engineer Harald Bode in the late 1950s. The 1960s saw the introduction of the Moog synthesizer and the Buchla Modular Electronic Music System, created around the same period. The Moog was composed of separate modules which created and shaped sounds, such as envelopes, noise generators, filters, and sequencers, connected by patch cords. The Japanese company Roland released the Roland System 100 in 1975, followed by the System 700 in 1976 and the System 100m in 1979. In the late 1970s, mod ...

Voltage-controlled Oscillator
A microwave (12–18GHz) voltage-controlled oscillator A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by applying a modulating signal to the control input. A VCO is also an integral part of a phase-locked loop. VCOs are used in synthesizers to generate a waveform whose pitch can be adjusted by a voltage determined by a musical keyboard or other input. A voltage-to-frequency converter (VFC) is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages. Types VCOs can be generally categorized into two groups based on the type of waveform produced. * ''Linear'' or '' harmonic oscillators'' generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Generator
A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. Theory There are several circuits used for noise generation. For example, temperature-controlled resistors, temperature-limited vacuum diodes, zener diodes, and gas discharge tubes. A source that can be switched on and off ("gated") is beneficial for some test methods. Noise generators usually rely on a fundamental noise process such as thermal noise or shot noise. Thermal noise generator Thermal noise can be a fundamental standard. A resistor at a certain temperature has a thermal noise associated with it. A noise generator might have two resistors at different temperatures and switch between the two resistors. The resulting output power is low. (For a 1 kΩ resistor at room temperature and a 10 kHz bandwidth, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Musical Instrument
An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or ..., creating the sound heard by the performer and listener. An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch (music), pitch, frequency, or duration of each Musical note, note. A common user interface is the musical keyboard, which functions similarly to the keyboard on an acoustic piano, except that with an electronic keyboard, the keyboard itself does not make any sound.

Sequential Circuits
Sequential is an American synthesizer company founded in 1974 as Sequential Circuits by Dave Smith. In 1978, Sequential released the Prophet-5, the first programmable polyphonic synthesizer; it became a market leader and industry standard, used by artists including Michael Jackson, Madonna, and John Carpenter. In the 1980s, Sequential was pivotal in the development of MIDI, a technical standard for synchronizing electronic instruments. In 1987, Sequential went out of business and was purchased by Yamaha. Smith continued to develop instruments through a new company, Dave Smith Instruments. In 2015, Yamaha returned the Sequential Circuits trademark to Dave Smith Instruments, which rebranded as Sequential in 2018. In 2021, Sequential was acquired by the British audio technology company Focusrite.
