An analog synthesizer is a synthesizer that uses analog circuits and analog signals to generate sound electronically.
Modular synthesizers are synthesizers composed of separate modules for different functions. The modules can be connected together by the user to create a patch. The outputs from the modules may include audio signals, analog control voltages, or digital signals for logic or timing conditions. Typical modules are voltage-controlled oscillators, voltage-controlled filters, voltage-controlled amplifiers and envelope generators.
The Yamaha AN1x is a DSP-based analog modeling synthesizer, produced by Yamaha Corporation from 1997 to 1998, and was marketed as an "analog physical modelling control synthesizer".
The ARP Odyssey is an analog synthesizer introduced by ARP Instruments in 1972.
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 Roland Jupiter-4 (JP-4) was an analog synthesizer manufactured by the Roland Corporation between 1978 and 1981. It was notable as the company's first self-contained polyphonic synthesizer, and for employing digital control of analog circuits, allowing for such features as programmable memory, voice assignment modes, an arpeggiator, polyphonic portamento and others.
The Moog Sonic Six is a duophonic analog synthesizer that was manufactured by Moog Music from 1972 to 1979. Because of its portable design and built-in speaker, the Sonic Six was widely used for lectures and educational purposes, often by Bob Moog himself.
The Korg Poly-61(PS-61) is an analog synthesizer manufactured by Korg between 1982 and 1986. It was the first affordable synthesizer to feature two oscillators per voice, and was Korg's first synthesizer to feature digitally-controlled analog oscillators (DCOs). The Poly-61 marked a significant departure in design philosophy from previous Korg synthesizers by replacing the traditional array of dedicated control knobs on the front panel with a digital interface that required users to select parameters individually for adjustment.
The Doepfer A-100 is an analog modular synthesizer system introduced by German audio manufacturer Doepfer in 1995. Although there were only 10 module types at time of release, it currently has more than 120 modules plus several different enclosures and accessories.
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.
The ARP Omni was a polyphonic analog synthesizer manufactured by ARP Instruments, Inc.
The Moog Prodigy was a monophonic analogue synthesizer produced by Moog Music from 1979 to 1984. Of the 11,000 produced, versions released after 1981 included a control voltage/gate input on the back that allowed the VCF to be triggered and controlled by an external source. These later versions began at serial number 4610. The official model number of the instrument is 336. 336A would indicate a domestic (US) model, while a 336BX would indicate an export unit.
The Korg MS-10 is an analogue synthesizer created by Korg in 1978. Unlike its bigger brother, the Korg MS-20, the MS-10 only has one VCO, one VCF and one envelope generator. It is monophonic and has 32 keys.
The Yamaha CS30/CS30L is an analog keyboard synthesizer that was released in 1977. It is the top of the range in Yamaha's original line-up of monophonic synthesizers, others in the range being the CS5, CS10 and CS15. It features two voltage controlled oscillators (VCOs), two voltage controlled filters, two voltage controlled amplifiers (VCAs) and three envelope generators. It also sports a ring modulator and a voltage controlled low-frequency oscillator (LFO).
The Korg DSS-1 is a polyphonic sampling synthesizer released by Korg in 1986. As Korg's initial entry into the sampling market, the DSS-1 combines sampling, additive synthesis, and waveform drawing with an analog signal path. The DSS-1 was released a time when major synthesizer manufacturers like Yamaha and Casio were beginning to explore sampling, an area of sound design dominated by companies like Fairlight, E-mu, and Ensoniq. Korg did not stay long in the sampling arena; the DSS-1 was the company's only sampler until 1998 when Korg introduced sampling options on their Triton and Trinity series of workstations.
Casio's SDSynthesizers were a late-1980s line of analog synthesizers featuring a resonant filter. SD synthesis was traditional DCO-analog synthesis, with the main difference being that some of the SD waveforms' harmonic spectrums changed temporally, or dynamically in relation to the amplitude envelope.
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 PS-3300 is a polyphonic analog synthesizer released by Korg in 1977. It was released alongside the PS-3100, a more compact variant featuring a complete synthesizer voice board for each of its 48 keyboard notes. The PS-3300 essentially combines three PS-3100 units, triggering all voices simultaneously with each key press and mirroring the PS-3100's overall design, featuring a total of 144 synth voices. The PS-3300 uses the PS-3010, a detachable keyboard equipped with an assignable joystick called the X-Y Manipulator.
The Steiner-Parker Synthacon is a monophonic analog synthesizer that was built between 1975 and 1979 by Steiner-Parker, a Salt Lake City-based synthesizer manufacturer. It was introduced as a competitor to other analog synthesizers, like the Minimoog and ARP Odyssey.
The Volca Modular is an analogue synthesizer manufactured by the Japanese music technology company Korg. It is part of their popular Volca series of affordable electronic synthesizers and drum machines. Like other Volcas, it sports a 16-step sequencer and can be powered by batteries.
