OB-X
The Oberheim OB-X was the first of Oberheim Electronics, Oberheim's OB-series polyphony (instrument), polyphonic Analog synthesizer, analog Subtractive synthesis, subtractive synthesizers. First commercially available in June 1979, the OB-X was introduced to compete with the Sequential Circuits Prophet-5, which had been successfully introduced the year before. About 800 units were produced before the OB-X was discontinued and replaced by the updated and streamlined Oberheim OB-Xa, OB-Xa in 1981. The OB line developed and evolved after that with the Oberheim OB-8, OB-8 before being replaced by the Oberheim Matrix synthesizers, Matrix series. The OB-X was used in popular music by Rush (band), Rush (on ''Moving Pictures (Rush album), Moving Pictures'' and ''Signals (Rush album), Signals''), Nena (band), Nena, Styx (band), Styx member Dennis DeYoung (used frequently from late 1979 to 1984), Queen (band), Queen (their first synthesizer on an album), Madonna for her Madonna (Madonna ...

Oberheim OB-Xa
The Oberheim OB-Xa was the second of Oberheim's OB-series polyphonic analog subtractive synthesizers, replacing the OB-X with updated features. History The OB-Xa was released in December 1980, replacing the OB-X after only a year on the market. The OB-Xa was the first Oberheim product adorned with blue horizontal pinstripes on black background that would become standard trade dress for future Oberheim products. While the OB-Xa offered the same polyphony as its predecessor (4, 6 and 8-voice models were offered), its keyboard could be split into two halves (each with its own voice) or to layer voices to create thicker sound (essentially making two notes sound for every key pressed). The OB-Xa also added the ability to switch between 2-pole 12dB and 4-pole 24dB filtering. It offered Filter Envelope modulation for oscillator 2 (which allows the pitch to be modulated by the envelope) in place of the OB-X's ability to cross modulate (frequency modulation of the first VCO with the sec ...

Oberheim Electronics
Oberheim is an American synthesizer manufacturer founded in 1969 by Tom Oberheim. History and products Tom Oberheim founded the company in 1969, originally as a designer and contract manufacturer of electronic effects devices for Maestro (most notably the Maestro PS-1A Phase Shifter),, and briefly a retail dealer for ARP Instruments, eventually designing the company's first Oberheim-branded product, the Oberheim DS-2, one of the first digital music sequencers. In 1975 Oberheim introduced the Synthesizer Expander Module (SEM) to complement the DS-2 sequencer and enable a user to play one synthesizer while the DS-2 played a sequence on another. The SEM featured a two-pole filter that could operate as a low-pass, high-pass, band-pass, or band-reject filter, giving it a different sound than the Moog and ARP filters popular at the time. The company later combined multiple SEM modules with a digitally-scanned keyboard and a 2-channel voltage-controlled sequencer to create a series o ...

Madonna (Madonna Album)
''Madonna'' (retitled ''Madonna: The First Album'' for the 1985 reissue) is the debut studio album by American singer-songwriter Madonna, released on July 27, 1983, by Sire Records. After having established herself as a singer in downtown New York City, Madonna was signed by Sire president Seymour Stein, due to the club success of her debut single, " Everybody" (1982). She became the sole writer for most of the album's tracks, and chose Reggie Lucas as its primary producer. Unhappy with Lucas's production outputs, she invited John "Jellybean" Benitez to complete the album; he remixed three tracks and produced "Holiday". ''Madonna'' has an upbeat synthetic disco sound, using new technology of the time, including the Linn drum machine, Moog bass and Oberheim OB-X synthesizer. She sang in a bright, girlish timbre, with lyrics about love and relationships. To promote the album, Madonna performed one-off gigs in clubs and on television in the United States and United Kingdom through ...

Oberheim Polyphonic
The Oberheim Polyphonic Synthesizer is a range of analog music synthesizers that was produced from 1975 to 1979 by Oberheim Electronics. It was developed by Tom Oberheim, and was the first production synthesizer capable of playing chords. Specification Oberheim took the idea and electronics of a Minimoog synthesizer and put them in a small box, making a few changes, and in 1974 introduced the SEM (Synthesizer Expander Module), which became the building block of his polyphonic synths. By strapping two, four, or eight of these SEMs together under keyboard control, he was able to create practical, albeit large, synthesizers that could play two, four, or eight notes simultaneously. The Oberheim Polyphonic Synthesizer was born. Each SEM in an Oberheim Polyphonic generates one voice (or note). There was an optional Polyphonic Synthesizer Programmer module (PSP-1) for the four- and eight-voice models with 16 memories, which allowed the user to store and recall some sound settings of ...

Synthesizers
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] |
Rush (band)
Rush was a Canadian rock band formed in 1968 in Toronto, that was comprised primarily of Geddy Lee (bass, vocals), Alex Lifeson (guitar), and Neil Peart (drums, percussion, lyricist). The band formed in Toronto in 1968 by Lifeson, drummer John Rutsey, and bass guitarist/vocalist Jeff Jones, who was immediately replaced by Lee. After Lee joined, the band went through several lineup configurations before arriving at its classic power trio lineup with the addition of Peart in July 1974, who replaced Rutsey four months after the release of their 1974 self-titled debut album; this lineup remained intact for the remainder of the band's career. Rush achieved commercial success in the 1970s with '' Fly by Night'' (1975), '' 2112'' (1976), ''A Farewell to Kings'' (1977) and '' Hemispheres'' (1978). The band's popularity continued throughout the 1980s and 1990s, with albums charting highly in Canada, the US and the UK, including '' Permanent Waves'' (1980), '' Moving Pictures'' (1981) ...

Moving Pictures (Rush Album)
''Moving Pictures'' is the eighth studio album by Canadian progressive rock band Rush, released on February 12, 1981 through Anthem Records. After touring to support their previous album, ''Permanent Waves'' (1980), the band started to write and record new material in August 1980 with co-producer Terry Brown. They continued to write songs with a more radio-friendly sound, featuring tighter and shorter song structures compared with their earlier albums. ''Moving Pictures'' received a positive reception from contemporary and retrospective music critics and became an instant commercial success, reaching number one in Canada and number 3 in both the United States and the United Kingdom. It remains Rush's highest-selling album in the United States, with 5 million copies sold. " Limelight", "Tom Sawyer" and "Vital Signs" were released as singles across 1981, and the instrumental "YYZ" was nominated for a Grammy Award for Best Rock Instrumental Performance.

Sample And Hold
In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time. Sample and hold circuits and related peak detectors are the elementary analog memory devices. They are typically used in analog-to-digital converters to eliminate variations in input signal that can corrupt the conversion process.Kefauver and Patschke, p. 37. They are also used in electronic music, for instance to impart a random quality to successively-played notes. A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET (field effect transistor) switch and normally one operational amplifier.Horowitz and Hill, p. 220. To sample the input signal, the switch connects the capacitor to the output of a buffer amplifier. The buffer ampli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
