Yamaha GX-1
The Yamaha GX-1, first released as Electone GX-707, is an analog polyphonic synthesizer organ developed by Yamaha as a test bed for later consumer synths and Electone series organs for stage and home use. The GX-1 has four synthesizer "ranks" or three manuals, called Solo, Upper, and Lower, plus Pedal, and an analog rhythm machine. The GX-707 first appeared in 1973 as a "theatre model" for use on concert stages, before the GX-1 was publicly released in 1975. Overview The Solo rank features a 3- octave keyboard with 37 keys that are full width but shorter than standard. Directly above the Solo keyboard runs the Portamento keyboard - a ribbon controller which can be used to play continuously variable pitches roughly corresponding to the Solo keyboard note below. The Portamento keyboard overrides the solo keyboard if used simultaneously. The Solo rank has only a single oscillator, but has a dedicated low-frequency oscillator (LFO), pitch envelope generator and ring modulator. ...

Yamaha Corporation
is a Japanese multinational corporation and conglomerate with a very wide range of products and services. It is one of the constituents of Nikkei 225 and is the world's largest musical instrument manufacturing company. The former motorcycle division was established in 1955 as Yamaha Motor Co., Ltd., which started as an affiliated company but later became independent, although Yamaha Corporation is still a major shareholder. History Nippon Gakki Co. Ltd. (currently Yamaha Corporation) was established in 1887 as a reed organ manufacturer by Torakusu Yamaha (山葉寅楠) in Hamamatsu, Shizuoka Prefecture and was incorporated on 12 October 1897. In 1900, the company started the production of pianos. The first piano to be made in Japan was an upright built in 1900 by Torakusu Yamaha, founder of Nippon Gakki Co., Ltd. — later renamed Yamaha Corporation. The company's origins as a musical instrument manufacturer are still reflected today in the group's logo—a trio of interloc ...

Envelope Generator
In sound and music, an envelope describes how a sound changes over time. It may relate to elements such as amplitude (volume), frequencies (with the use of filters) or pitch. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero. Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments. The most common form of envelope generator is controlled with four parameters: attack, decay, sustain and release (ADSR). Development The Hammond Novachord in 1938 used an early implementation of an ADSR envelope. A seven-position rotary knob selects preset ADS parameter for all 72 notes; a pedal controls the release. The envelope generator was created by the American engineer Robert Moog in the 1960s. While experimenting with the first Moog synthesizers, composer Herbert Deutsch suggested Moo ...

Works Volume 1
''Works Volume 1'' is the fifth studio album by English progressive rock band Emerson, Lake & Palmer, released as a double album in March 1977 on Atlantic Records. Following their world tour supporting ''Brain Salad Surgery'' (1973), the group took an extended break before they reconvened in 1976 to record a new album. They were now tax exiles and recorded new material in London and overseas in Montreux, Switzerland and Paris, France. ''Works Volume 1'' features a side dedicated for each member to write and arrange their own tracks, while the fourth side features songs performed collectively. Keith Emerson recorded his Piano Concerto No. 1, Greg Lake wrote several songs with lyricist Peter Sinfield, and Carl Palmer recorded tracks of varied musical styles. The album peaked at No. 9 on the UK Albums Chart and No. 12 on the US ''Billboard'' 200 and went gold in both countries, the latter for 500,000 copies sold. The group track "Fanfare for the Common Man", Emerson's adapta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emerson, Lake & Palmer
Emerson, Lake & Palmer (informally known as ELP) were an English progressive rock supergroup formed in London in 1970. The band consisted of Keith Emerson (keyboards), Greg Lake (vocals, bass, guitar, producer) and Carl Palmer (drums, percussion). With nine RIAA-certified gold record albums in the US, and an estimated 48 million records sold worldwide, they are one of the most popular and commercially successful progressive rock groups of the 1970s, with a musical sound including adaptations of classical music with jazz and symphonic rock elements, dominated by Emerson's flamboyant use of the Hammond organ, Moog synthesizer, and piano (although Lake wrote several acoustic songs for the group).Lake says almost dismissively, "It used to be a thing where as a balance to the record I would write an acoustic song." Lake's ballads, the least typical aspect of ELP's music, often garnered the band their greatest airplay and widest public exposure. The band came to prominence followin ...

Keith Emerson
Keith Noel Emerson (2 November 1944 – 11 March 2016) was an English keyboardist, songwriter, and record producer. He played keyboards in a number of bands before finding his first commercial success with the Nice in the late 1960s. He became internationally famous for his work with the Nice, which included writing rock arrangements of classical music. After leaving the Nice in 1970, he was a founding member of Emerson, Lake & Palmer (ELP), one of the early progressive rock supergroups. Emerson, Lake & Palmer were commercially successful through much of the 1970s, becoming one of the best-known progressive rock groups of the era. Emerson wrote and arranged much of ELP's music on albums such as '' Tarkus'' (1971) and '' Brain Salad Surgery'' (1973), combining his own original compositions with classical or traditional pieces adapted into a rock format. Following ELP's break-up at the end of the 1970s, Emerson pursued a solo career, composed several film soundtracks, and forme ...

Paul Davis (singer)
Paul Lavon Davis (April 21, 1948 – April 22, 2008) was an American singer and songwriter, best known for his radio hits and solo career which started worldwide in 1970. His career encompassed soul, country, and pop. His most successful songs are 1977's " I Go Crazy", a No. 7 pop hit which once held the record for the longest chart run on the ''Billboard'' Hot 100, and 1982's " '65 Love Affair", which at No. 6 is his highest-charting single. Another pop hit, " Cool Night", was released in 1981. In the mid-1980s, he also had two No. 1 country hits as a guest vocalist on songs by Marie Osmond and Tanya Tucker. Career Davis was born in Meridian, Mississippi, United States. He was a member of a local group called the Six Soul Survivors around 1966 and later in another group called the Endless Chain. In 1968, he was a writer for Malaco Records, based in Jackson, Mississippi. Ilene Berns, widow of Bert Berns, signed Davis to Bang Records in 1969, and in 1970, released a cover versio ...

Yamaha CS-80
The Yamaha CS-80 is an analog synthesizer released in 1977. It supports true 8-voice polyphony, with two independent synthesizer layers per voice each with its own set of front panel controls, in addition to a number of hardwired preset voice settings and four parameter settings stores based on banks of subminiature potentiometers (rather than the digital programmable presets the Prophet-5 would sport soon after). It has exceptionally complete performer expression features, such as a layered keyboard that was both velocity-sensitive (like a piano's) and pressure-sensitive (" after-touch") but unlike most modern keyboards the aftertouch could be applied to individual voices rather than in common, and a ribbon controller allowing for polyphonic pitch-bends and glissandos. Production of the instrument ceased in 1980. Vying with the Sequential Circuits Prophet-5 and Oberheim OB-X polysynths for the title, the CS-80 is often described as the pre-eminent polyphonic analog synthe ...

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 "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses suc ...

Polymoog
The Polymoog is a hybrid polyphonic analog synthesizer that was manufactured by Moog Music from 1975 to 1980. The Polymoog was based on divide-down oscillator technology similar to electronic organs and string synthesizers of the time. History The name Polymoog can refer either to the original Polymoog Synthesizer (model 203a) released in 1975, or the largely preset Polymoog Keyboard (model 280a) released in 1978. The Polymoog has a 71-note weighted Pratt & Read touch-sensitive keyboard divided into three sections with a volume slider for each. It also has a three-band resonant graphic equalizer section, which can be changed to a low/bandpass/high-pass filter. The Moog-designed 24 dB/octave filter section allows modulation modulated from its own envelopes, low frequency oscillation and sample and hold circuit. Ranks and waveforms of all notes are also adjustable combining waveforms, octaves, tunings, and their own independent LFO rates and amounts. The user can ad ...

Square Wave
A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. In an ideal square wave, the transitions between minimum and maximum are instantaneous. The square wave is a special case of a pulse wave which allows arbitrary durations at minimum and maximum amplitudes. The ratio of the high period to the total period of a pulse wave is called the duty cycle. A true square wave has a 50% duty cycle (equal high and low periods). Square waves are often encountered in electronics and signal processing, particularly digital electronics and digital signal processing. Its stochastic counterpart is a two-state trajectory. Origin and uses Square waves are universally encountered in digital switching circuits and are naturally generated by binary (two-level) logic devices. Square waves are typically generated by metal–oxide–semiconductor fiel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-pass Filter
A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The amount of attenuation for each frequency depends on the filter design. A high-pass filter is usually modeled as a linear time-invariant system. It is sometimes called a low-cut filter or bass-cut filter in the context of audio engineering. High-pass filters have many uses, such as blocking DC from circuitry sensitive to non-zero average voltages or radio frequency devices. They can also be used in conjunction with a low-pass filter to produce a bandpass filter. In the optical domain filters are often characterised by wavelength rather than frequency. High-pass and low-pass have the opposite meanings, with a "high-pass" filter (more commonly "long-pass") passing only ''longer'' wavelengths (lower frequencies), and vice versa for "low-pass" (more commonly "short-pass").
