Oberheim SEM
The Oberheim Polyphonic Synthesizer is a series of analog music synthesizers that was produced from 1975 to 1979 by Oberheim Electronics. Developed by Tom Oberheim, they were the first production synthesizers capable of playing chords. Background After Oberheim introduced the DS-2 digital music sequencer, Tom Oberheim recognized that customers wanted to play one synthesizer while the DS-2 played a sequence on another, or layer the sound of one synthesizer with another. To address this need, he introduced the Synthesizer Expander Module (SEM), a semi-modular analog synthesizer module, in 1974. The SEM featured two VCOs and a two-pole voltage-controlled 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 four-pole low-pass ladder filters popular at the time. Specification In late 1975, after Norlin canceled several large Maestro orders, Oberheim developed a series of polyphonic synthesizers b ...

Oberheim Electronics
Oberheim is an American synthesizer manufacturer founded in 1969 by Tom Oberheim. Beginning in 1975, Oberheim developed some of the first commercially available polyphonic synthesizers and was a prominent synthesizer and drum machine manufacturer through the mid-1980s. In 1988, the company changed ownership and was eventually purchased by Gibson Guitar Corporation, which developed new Oberheim products and licensed the trademark to other companies that produced Oberheim products, but development of Oberheim products ceased after 2000. In 2009, Tom Oberheim began developing instruments through his own company, and in 2019, Gibson returned the Oberheim trademark to Tom Oberheim, whose company rebranded as Oberheim. History and products Beginnings and first polyphonic synthesizers Tom Oberheim founded the company in 1969, originally as a designer and contract manufacturer of electronic effects devices for Chicago Musical Instruments under their Maestro brand, including the PS-1A ...

Band-pass Filter
A band-pass filter or bandpass filter (BPF) is a device that passes frequencies within a certain range and rejects ( attenuates) frequencies outside that range. It is the inverse of a '' band-stop filter''. Description In electronics and signal processing, a filter is usually a two-port circuit or device which removes frequency components of a signal (an alternating voltage or current). A band-pass filter allows through components in a specified band of frequencies, called its ''passband'' but blocks components with frequencies above or below this band. This contrasts with a high-pass filter, which allows through components with frequencies above a specific frequency, and a low-pass filter, which allows through components with frequencies below a specific frequency. In digital signal processing, in which signals represented by digital numbers are processed by computer programs, a band-pass filter is a computer algorithm that performs the same function. The term band ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oberheim 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 (company), 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 (on ''The Game (Queen album), The Game'', their fir ...

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.

Manual (music)
The word "manual" is used instead of the word "keyboard" when referring to any hand-operated keyboard on a keyboard instrument that has a Pedal keyboard, pedalboard (a keyboard on which notes are played with the feet), such as an organ; or when referring to one of the keyboards on an instrument that has more than one hand-operated keyboard, such as a two- or three-manual harpsichord. (On instruments that have neither a pedalboard nor more than one hand-operated keyboard, the word "manual" is ''not'' a synonym for "keyboard".) Music written to be played only on the manuals (and not using the pedals) can be designated by the word manualiter (first attested in 1511, but particularly common in the 17th and 18th centuries). Overview Organs and synthesizers can, and usually do, have more than one manual; most home instruments have two manuals, while most larger organs have two or three. Elaborate pipe organs and theater organs can have four or more manuals. The manuals are set into th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portamento
In music, portamento (: ''portamenti''; from old , meaning 'carriage' or 'carrying'), also known by its French name glissade, is a pitch sliding from one Musical note, note to another. The term originated from the Italian language, Italian expression ('carriage of the voice'), denoting from the beginning of the 17th century its use in vocal performances and emulation by members of the violin family and certain wind instruments, and is sometimes used interchangeably with Nonchord tone#Anticipation, anticipation. It is also applied to one type of glissando on, e.g., slide trombones, as well as to the "glide" function of Pedal steel guitar, steel guitars and synthesizers. Vocal portamento In the first example, Rodolfo's first aria in ''La sonnambula'' (1831), the portamento is indicated by the Slur (music), slur between the third and fourth notes. The second example, Judit's first line in ''Bluebeard's Castle'' (1912) by composer Béla Bartók, employs an inclining, wavy line b ...

Oberheim Two Voice
The Oberheim Two Voice (TVS) is an analogue synthesizer produced by Oberheim Electronics from 1975 to 1979. It can be operated in either polyphonic or monophonic mode, and includes an onboard 8-step sequencer. The Two Voice was the first of Oberheim's Polyphonic Synthesizer series, and one of the first commercially-available polyphonic synthesizers. Development At the start of 1975, Oberheim did not consider itself a synthesizer manufacturer. At the time, the company's business consisted of contract manufacturing Maestro-branded effects units, as well its own products, the DS-2 digital music sequencer and Synthesizer Expansion Module, which were intended as add-ons for Minimoog and ARP 2600 owners. When Norlin canceled several large Maestro orders, the company was forced to develop new products to replace those lost sales. By combining multiple SEM synthesizer modules with a digitally-scanned keyboard developed by Dave Rossum and a two-channel sequencer, Oberheim created ...

Dave Rossum
David P. Rossum (born 1948) is an American electronics engineer and inventor best known as the co-founder of synthesizer and sampler manufacturer E-mu Systems. Education and early career Rossum grew up in the San Francisco Bay Area and attended the California Institute of Technology (Caltech), earning a Bachelor of Science in Biology in 1970. Later that year while pursuing graduate studies at the University of California at Santa Cruz, Rossum's advisor, Harry Noller, invited him to join him in the music department where students were unpacking the university's new Moog Model 12 modular synthesizer. Rossum discovered an affinity for synthesis and invited his Caltech friends Steve Gabriel and Jim Ketcham to come see the Model 12. Together, they were inspired to start designing a synthesizer. In 1971 Ketcham heard there was a request for bid from the San Diego School District for music synthesizers to add to their high school music program, and Rossum and his friends decided t ...
