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 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 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 microKORG is a MIDI-capable digital synthesizer/vocoder from Korg featuring DSP-based analog modelling. The synthesizer is built in such a way that it is essentially a Korg MS-2000 with a programmable step arpeggiator, a less advanced vocoder, lack of motion sequencing, lack of an XLR microphone input, and in a smaller case with fewer real-time control knobs.
The Korg DW-8000 is a polyphonic hybrid digital-analog synthesizer released in 1985. It blends digital waveforms with an analog filter and amplifier, followed by a digital delay for adding echo effects. It boasts eight-note polyphony and its keyboard is equipped with velocity sensitivity and aftertouch.
The Korg Prophecy is a monophonic synthesizer released by Korg in 1995. one of the earliest commercial DSP physical/acoustic and analog "virtual" modeling sound synthesizers and Korg's first monophonic synthesizer since the Mono/Poly. The Prophecy employs Korg's Multi Oscillator Synthesis System (MOSS), which features digital oscillators capable of emulating synthesis techniques such as analog synthesis, FM and physical modelling. Emphasized for its portability, expressiveness, and engaging playability, a distinctive feature of the Prophecy is its multifunctional Wheel 3, nicknamed the 'log'.
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 Wavestation is a vector synthesis synthesizer first produced in the early 1990s and later re-released as a software synthesizer in 2004. Its primary innovation was Wave Sequencing, a method of multi-timbral sound generation in which different PCM waveform data are played successively, resulting in continuously evolving sounds. The Wavestation's "Advanced Vector Synthesis" sound architecture resembled early vector synths such as the Sequential Circuits Prophet VS.
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 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.
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 Evolver is an analog-digital hybrid synthesizer designed by Dave Smith and manufactured by Dave Smith Instruments. It was first released as a desktop version in 2002, then later a 37-key keyboard bearing the same synth engine as the Evolver desktop was also released. A polyphonic version of the Evolver, dubbed the Poly Evolver, was released in 2004 as a rackmount version, then a 61-key keyboard version of the Poly Evolver was released in 2005. The Evolvers were replaced by new high end models, the Prophet 12 and the Pro 2.
The Korg DS-8 is a digital eight-voice FM synthesizer released by Korg in 1987. Following an agreement with Yamaha for access to its research and development facilities, it was designed using Yamaha components and constructed under a licensing agreement. It introduced an analog-style interface for controlling FM sounds and could play different patches on each of its eight voices, marking it as Korg's first multi-timbral MIDI synthesizer. Accompanying its launch was the Korg 707, a more portable version of the DS-8, lacking digital effects but equipped with strap pegs for keytar performance.
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 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 CZ series is a family of low-cost phase distortion synthesizers produced by Casio in the mid-1980s. Eight models of CZ synthesizers were released: the CZ-101, CZ-230S, CZ-1000, CZ-2000S, CZ-2600S, CZ-3000, CZ-5000, and the CZ-1. Additionally, the home-keyboard model CT-6500 used 48 phase distortion presets from the CZ line. The CZ synthesizers' price at the time of their introduction made programmable synthesizers affordable enough to be purchased by garage bands. Yamaha soon introduced their own low-cost digital synthesizers, including the DX-21 (1985) and Yamaha DX100, in light of the CZ series' success.
The Korg Z1 is a digital synthesizer released by Korg in 1997. The Z1 built upon the foundation set by the monophonic Prophecy released two years prior by offering 12-note polyphony and featuring expanded oscillator options, a polyphonic arpeggiator and an XY touchpad for enhanced performance interaction. It was the world's first multitimbral physical modelling synthesizer.
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 miniKORG 700 is a monophonic analog synthesizer released by Korg in 1973, marking their entry into mass-produced synthesizers and their first monophonic synthesizer. It was initially designed to be placed on top of an organ, so its controls are located below the keyboard facing towards the performer. An updated model, the miniKORG 700S, was launched in 1974, introducing a second oscillator that could be detuned, along with additional sustain and vibrato controls.
The Volca Keys is an analogue synthesizer manufactured by the Japanese music technology company Korg. It was announced in April 2013 at MusikMesse and was at the time one of the few affordable analogue synthesizers available. The Volca Keys uses subtractive synthesis to create sounds and is three-note paraphonic, meaning that it can play chords with all voices sharing a single voltage-controlled filter (VCF).
