Frequency modulation synthesis is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal.
The MOS Technology 6581/8580 SID is the built-in programmable sound generator chip of the Commodore CBM-II, Commodore 64, Commodore 128, and MAX Machine home computers.
The Elektron SidStation is a musical synthesizer sound module, built around the MOS Technology SID mixed-mode synthesizer chip originally used in the Commodore 64 home computer. It was produced by the Swedish synthesizer company Elektron, and was introduced in 1999. As the SID chip had not been manufactured for years, Elektron allegedly bought up nearly all the remaining stock.
Novation Digital Music Systems Ltd. is a British musical equipment manufacturer, founded in 1992 by Ian Jannaway and Mark Thompson as Novation Electronic Music Systems. Today the company specializes in MIDI controllers with and without keyboards, both analog and virtual analog performance synthesizers, grid-based performance controllers, and audio interfaces. At present, Novation products are primarily manufactured in China.
A rompler is an electronic musical instrument that plays pre-fabricated sounds based on audio samples. The term rompler is a blend of the terms ROM and sampler. In contrast to samplers, romplers do not record audio. Both may have additional sound editing features, such as layering several waveforms and modulation with ADSR envelopes, filters and LFOs.
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".
Elektron is a Swedish developer and manufacturer of musical instruments founded in 1998, as well as having its headquarters, R&D and production in Gothenburg, Sweden. They produce mainly electronic musical instruments, but have also made effects units and software. Since 2012, there have been branch offices in Los Angeles and in Tokyo.
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 Trinity is a synthesizer and music workstation released by Korg in 1995. It was Korg's first modern workstation and marked a significant evolution from its predecessors by offering features such as built-in digital audio recording, 32-note polyphony, an extensive internal sound library, assignable effects, and a large touchscreen for advanced control and editing functions, a feature not previously seen on any musical instrument. It also offered modular expansion for not only sounds, but also studio-grade features such as ADAT, various sound engine processors, audio recording capability, and more.
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. In 2024 Access Music discontinued the TI2.
The Fantom-X (Xa/X6/X7/X8/XR) is a music workstation/synthesizer produced by Roland Corporation. It was introduced in 2004 as an upgrade from the Fantom S series. The Fantom-X competes with the Korg Triton/Triton Extreme, the Yamaha Motif ES and other similar large-scope keyboards such as the discontinued Alesis Fusion. In 2008 it was succeeded by the Fantom-G*, which was devised to compete with the new Korg and Yamaha flagship keyboards.
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 Ensoniq TS-10 was a synthesizer and music workstation introduced by Ensoniq in 1993. It provided synthesis, user sample playback, sequencer, effect units and performance facilities in a 61-key package.
The Ensoniq VFX Synth was initially released as a performance type synthesizer in 1989. It was soon followed by the release of the VFX-SD, which included some updated waveforms, a 24-track sequencer and a floppy drive. Both models were equipped with the Ensoniq Signal Processing (ESP) chip for 24-bit effects. The VFX-SD also included two AUX outs, which allowed for a total of 4 outputs from the synth for more routing flexibility. The initial models were 21-voice polyphony, and in latter models of the VFX-SD (I/II) and the SD-1, the polyphony was 32.
The Roland XP-50 is a music workstation that combines the synthesizer engine of Roland's JV-1080 sound module with the sequencing capabilities of their MRC-Pro sequencer and a 61-note keyboard. First released in 1995, the XP-50 and the Roland XP-10 were the first two Roland XP-series products, later joined by the XP-80 and XP-30.
The Korg RADIAS is a virtual analog synthesizer and Vocoder, released by Korg in 2006. The RADIAS' MMT engine was based on the Korg OASYS synthesizer module, providing for several different synthesis methods, two of which may be combined in a single voice e.g. phase distortion synthesis can be combined with subtractive synthesis. The different synthesis methods employed by MMT represent the majority of methods used historically in other Korg synthesizers: digital waveguide synthesis Korg first used in the Korg Z1 and phase distortion synthesis was first used in the Korg DS-8. This flexibility allows for very realistic emulations of past Korg synthesizers, though stays away from trying to emulate the Korg M1 and the Korg Wavestation,. As well as using the in-built waveforms for the basis of sound creation, the RADIAS allows for the input of an external signal which may be routed through the various sound shaping devices. The RADIAS has a comprehensive matrix modulation specification and to further enhance a sound the 'Wave Shaper' module allows for various sound distortion effects.
The Sirius is a keyboard "groove-synth," featuring a subtractive hybrid-tone-generation synthesizer referred to as DTE synthesis introduced in 1997 by Quasimidi. The unit featured both real-time and step sequencers with pattern- and song-modes, capable of acting basic drum machine, groove-box, or sound-module.
