An analog synthesizer is a synthesizer that uses analog circuits and analog signals to generate sound electronically.
Oberheim is an American synthesizer manufacturer founded in 1969 by Tom Oberheim.
Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but was an early Music Workstation. Although its voice generation is typically subtractive in much the same fashion as most analog synthesizers that preceded it, its oscillators are neither voltage nor "digitally controlled", but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.
The Jupiter-8, or JP-8, is an eight-voice polyphonic analog subtractive synthesizer introduced by Roland Corporation in early 1981.
The ARP Odyssey is an analog synthesizer introduced by ARP Instruments in 1972.
The Oberheim OB-X was the first of Oberheim's OB-series polyphonic analog subtractive synthesizers.
The Realistic Concertmate MG-1 is an analog synthesizer manufactured by Moog Music in 1981 and sold by Radio Shack from 1982 to 1983 under their "Realistic" brand name. It was produced without some standard Moog features, such as pitch and modulation wheels, as a cost-cutting measure aimed at achieving a lower price for the consumer market. The synthesizer also featured a pair of pass-through RCA jacks, which allowed users to mix radio or records into the final live synthesized sound output.
The Korg MS-20 is a patchable semi-modular monophonic analog synthesizer which Korg released in 1978 and which was in production until 1983. It was part of Korg's MS series of instruments, which also included the single oscillator MS-10, the keyboardless MS-50 module, the SQ-10 sequencer, and the VC-10 Vocoder. Additional devices included the MS-01 Foot Controller, MS-02 Interface, MS-03 Signal Processor, and MS-04 Modulation Pedal.
The Access Virus is a virtual analog synthesizer made by the German company Access Music GmbH. It was first produced in 1997 and has since been upgraded frequently, with the company releasing new models about every two years. Early models include the Virus A, Virus B, and Virus C series, each available in various hardware configurations. In November 2005, the Virus TI series was released, including the 61-key Virus TI Keyboard and the 37-key Virus TI Polar. A small desktop model was released in February 2008 called the Virus TI Snow. A revision of the TI series called TI2 came out in March 2009, featuring faster digital signal processing (DSP) controllers, additional polyphony, more effects in the effect section and a slightly changed design. The Virus series also has come out with two software plugin versions: TDM for Pro Tools and VST for TC Electronic Powercore series. The term Access Virus can be used to refer to any one of these synthesizers.
The Memorymoog is a polyphonic electronic music synthesizer manufactured by Moog Music from 1982 to 1985, the last polyphonic synthesizer to be released by Moog Music before the company declared bankruptcy in 1987. While comparable to other polyphonic synthesizers of the time period, such as the Sequential Circuits Prophet-5 and Oberheim OB-Xa, the Memorymoog distinguished itself with an additional, 3rd audio oscillator per voice and greater preset storage capacity.
The Oberheim OB-8 is a subtractive analog synthesizer launched by Oberheim in early 1983 and discontinued in 1985. As the fourth product in the OB-series of polyphonic compact synthesizers, the OB-8 was the successor to the OB-Xa. The number of production was about 3,000 units.
The Oberheim OB•12 is a Virtual Analog synthesizer, designed and realised by the Italian musical instrument manufacturer Viscount, in production between 2000 and 2005.
Thomas Elroy Oberheim, known as Tom Oberheim, is an American audio engineer and electronics engineer best known for designing effects processors, analog synthesizers, sequencers, and drum machines. He has been the founder of four audio electronics companies, most notably Oberheim Electronics. He was also a key figure in the development and adoption of the MIDI standard. He is also a trained physicist.
A synthesizer 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.
The Oberheim Xpander is an analog synthesizer launched by Oberheim in 1984 and discontinued in 1988. It is essentially a keyboardless, six-voice version of the Matrix-12. Utilizing Oberheim's Matrix Modulation technology, the Xpander combined analog audio generation with the flexibility of digital controls logic.
The Korg Mono/Poly (MP-4) is a 44 key "mono-polyphonic" analog synthesizer manufactured by Korg from 1981 to 1984. This keyboard is the sister synthesizer to the Korg Polysix. It has four highly stable voltage-controlled oscillators (VCOs), a 4-pole, self-oscillating low pass filter (LPF), wide modulation capabilities and pseudo-polyphony (paraphony).
The Split-8 is a polyphonic analogue keyboard synthesizer manufactured by Sequential Circuits. Built in Japan and going by the alternative name Pro-8 in some markets, this was one of the last synthesizers produced by the company and was assigned model number 608. It was released in 1985 at a list price of $1,199. This and some other Sequential Circuits synthesizers were built around the Curtis Electronics CEM 3394 "synth-on-a-chip" integrated circuit, and used a Z80 as their central microprocessor.
The Roland MKS-80 Super Jupiter is a rack mount sound module version of the Roland Jupiter-6 and the Roland Jupiter-8 synthesizers. It is an 8-voice polyphonic analog synthesizer that was manufactured by Roland between 1984 and 1987. It is the only one of the MKS series of synthesizers to have analogue voltage-controlled oscillators (VCOs) instead of analogue digitally-controlled oscillators (DCOs). The voice architecture is almost identical to the Jupiter-6 synthesizer. The service manual states that "The module board of MKS-80 features the following in addition to that of JP-6, its brother module. 1) HPF. 2) Low boost circuit in the 2nd VCA. 3) DC supply current boost circuit (IC50)."
The AX60 is a polyphonic analogue keyboard synthesizer manufactured by Akai Professional in the mid-1980s. It was Akai's answer to the popular Roland Juno series synthesizers. The AX60 uses voltage-controlled analogue oscillators and filter circuitry based on the Curtis Electronics CEM 3394 integrated circuit.
The Neutron is a dual-oscillator monophonic synthesizer manufactured by Behringer. Released in 2018, the Neutron has an analogue signal path and uses subtractive synthesis to produce sounds. It is semi-modular and compatible with Eurorack voltages.
