Yamaha GX-1
The Yamaha GX-1, first released as Electone GX-707, is an analog polyphony (instrument), polyphonic synthesizer developed by Yamaha Corporation, 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 Manual (music), 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 Synthesizer#Fingerboard controller, 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 d ...

Yamaha Corporation
is a Japanese multinational musical instrument and audio equipment manufacturer. 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 has been spun-off as its own independent company. History was established in 1887 as a reed organ manufacturer by Torakusu Yamaha () in Hamamatsu, Shizuoka Prefecture, and was incorporated on 12 October 1897. In 1900, the company manufactured the first piano to be made in Japan, and its first grand piano two years later. In 1987, 100 years after the first reed organ built by Yamaha, the company was renamed Yamaha Corporation in honor of its founder. The company's origins as a musical instrument manufacturer are still reflected today in the group's logo—a trio of interlocking tuning forks. After World War II, company president Genichi Kawakami repur ... [...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 elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Works Volume 2
''Works Volume 2'' is the sixth studio album by Emerson, Lake & Palmer, released on 25 November 1977. Unlike ''Works Volume 1'' (which consisted of three solo sides and one ensemble side), ''Works Volume 2'' was a single album compilation of leftover tracks from other album sessions, similar to the Who's '' Odds & Sods'' or Led Zeppelin's '' Coda''. While many derided the album for its apparent lack of focus, others praised it for showing a different side of the band than usual, with blues, bluegrass and jazz being very prominent as musical genres in this recording. The remastered 2017 version of the album is expanded to a double-CD by the inclusion of the complete ''Works Live'', an extended version of '' Emerson, Lake & Palmer in Concert''. Songs "When the Apple Blossoms Bloom...", " Tiger in a Spotlight" and "Brain Salad Surgery" had been recorded at the 1973 sessions for the album '' Brain Salad Surgery'' but did not appear on it. The funk-fusion tinged "Apple Blossoms" f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Works Volume 1
''Works Volume 1'' is the fifth studio album by English progressive rock band Emerson, Lake & Palmer, released as a double album on 25 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 Switzerland, officially the Swiss Confederation, is a landlocked country located in west-central Europe. It is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland ... and Paris, France.

Emerson, Lake & Palmer
Emerson, Lake & Palmer (informally known as ELP) were an English progressive rock Supergroup (music), supergroup formed in London in 1970. The band consisted of Keith Emerson (keyboards) of The Nice, Greg Lake (vocals, bass, guitars, producer) of King Crimson, and Carl Palmer (drums, percussion) of Atomic Rooster. With nine Recording Industry Association of America, 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, oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keith Emerson
Keith Noel Emerson (2 November 194411 March 2016) was an English keyboardist, songwriter, composer 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 ...

Loudspeaker
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The driver is a linear motor connected to a diaphragm, which transmits the motor's movement to produce sound by moving air. An audio signal, typically originating from a microphone, recording, or radio broadcast, is electronically amplified to a power level sufficient to drive the motor, reproducing the sound corresponding to the original unamplified signal. This process functions as the inverse of a microphone. In fact, the ''dynamic speaker'' driver—the most common type—shares the same basic configuration as a dynamic microphone, which operates in reverse as a generator. The dynamic speaker was invented in 1925 by Edward W. Kellogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 adju ...

Square Wave (waveform)
A square wave is a non-sinusoidal waveform, 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. They are used as timing references or "clock signa ... [...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 band-pass 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 "short-pass") passing only ''shorter'' wavelengths (higher frequencies), and vice versa for "low-pass" (more commonly "long-pass").

Sawtooth Wave
The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform. The convention is that a sawtooth wave ramps upward and then sharply drops. In a reverse (or inverse) sawtooth wave, the wave ramps downward and then sharply rises. It can also be considered the extreme case of an asymmetric triangle wave. The equivalent piecewise linear functions x(t) = t - \lfloor t \rfloor x(t) = t \bmod 1 based on the floor function of time ''t'' is an example of a sawtooth wave with period 1. A more general form, in the range −1 to 1, and with period ''p'', is 2\left( - \left\lfloor + \right\rfloor\right) This sawtooth function has the same phase as the sine function. While a square wave is constructed from only odd harmonics, a sawtooth wave's sound is harsh and clear and its spectrum cont ...
