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 ARP Odyssey is an analog synthesizer introduced by ARP Instruments in 1972.
The Korg OASYS is a workstation synthesizer released in early 2005, 1 year after the successful Korg Triton Extreme. Unlike the Triton series, the OASYS uses a custom Linux operating system that was designed to be arbitrarily expandable via software updates, with its functionality limited only by the PC-like hardware.
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 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 Korg Polysix(PS-6) is a six-voice polyphonic analog synthesizer released by Korg in 1981. It was one of the first affordable polyphonic synthesizers on the market, and was released as a cheaper alternative to the Sequential Prophet-5 and Oberheim OB-X, priced at approximately a third of the cost of its contemporaries in the polysynth market. It includes one VCO per voice, enhanced by a chorus/ensemble effect for added richness. It also comes equipped with 32 program memories and an integrated arpeggiator.
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 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 Roland GR-500 is a guitar synthesizer. Manufactured by the Roland Corporation and FujiGen in 1977, it was one of the first guitar synthesizers.
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 paraphonic analog synthesizer released by Korg in 1981, bridging the gap between monophonic and polyphonic synthesis. Released in the same year as the Korg Polysix, as a complementary synth, The Mono/Poly is equipped with four VCOs and can operate as a four-voice paraphonic synth with limited capabilities, or as a monophonic synth using all four oscillators. Upon its release, it was the only monophonic synthesizer with an integrated quad-VCO design available on the market.
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.
SN76477 "complex sound generator" is a sound chip produced by Texas Instruments (TI). The chip came to market in 1978, and TI ceased production of the part. A compatible version is identified as ICS76477. The chip is typically used as a sound effects generator in arcade games and toys and for hobby projects. The use of the SN76477 in a musical context is limited by the fact that it was difficult to electronically control the pitch of the produced sound.
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 Arturia MiniBrute is a synthesizer manufactured by Arturia. Although the MiniBrute was the first piece of analog hardware created by Arturia—which had previously exclusively marketed software synthesizers—it generated strong sales.
The Korg Minilogue is a polyphonic analog synthesizer released in 2016 by Korg. It offers users four-voice polyphony with two analog VCOs per-voice and was designed to be affordable. It was designed by Korg engineer and synthesizer designer Tatsuya Takahashi, who said "the concept of the Minilogue was to build an analog synthesizer that doesn't rely on the fame and success of an old synth".
The Korg Trident is a polyphonic multi-section synthesizer released by Korg in 1980, combining three distinct synthesizers within a single instrument: a polyphonic section with two VCOs, alongside dedicated String and Brass sections. The polyphonic synthesizer section allows for eight-note polyphony with dual oscillators. The String section offers an ensemble effect and simple attack/release envelope controls, whereas the Brass section features an independent filter and a dedicated ADSR envelope. These sections can be assigned to two different regions of the keyboard independently, and the Trident also offers a flanger effect along with a joystick for pitch bending and modulation.
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.
