The Korg OASYS PCI is a DSP-based PCI-card for PC and Mac released in 1999. It offers many synthesizer engines from sampling and substractive to FM and physical modelling. Because of its high market price and low polyphony production was stopped in 2001. About 2000 cards were produced.
Some of the models were taken from Korg Z1 hardware synthesizer.
Korg released Synth Kit software for Mac OS 9 for extensions developing. Some of addition plugins were released to expand card capabilities:
The Korg OASYS workstation synthesizer released in early 2005.
Korg's longstanding OASYS synthesis project has finally come to commercial fruition. The original plan, to produce a traditional stand-alone synthesizer, has given way to a computer-based synthesis and mixing environment running on a multi-DSP PCI card. Simon Trask takes refuge with the OASYS PCI...(see also a column on this article: "Native Vs DSP: Dan Phillips (Korg R&D) On Processing Power")
A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds. This in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments. Some digital synthesizers emulate analog synthesizers; others include sampling capability in addition to digital synthesis.
Physical modelling synthesis refers to sound synthesis methods in which the waveform of the sound to be generated is computed using a mathematical model, a set of equations and algorithms to simulate a physical source of sound, usually a musical instrument.
An analogsynthesizer is a synthesizer that uses analog circuits and analog signals to generate sound electronically.
A software synthesizer, also known as a softsynth or software instrument, is a computer program or plug-in that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional synthesizer. Softsynths are usually cheaper and more portable than dedicated hardware, and easier to interface with other music software such as music sequencers.
Digital waveguide synthesis is the synthesis of audio using a digital waveguide. Digital waveguides are efficient computational models for physical media through which acoustic waves propagate. For this reason, digital waveguides constitute a major part of most modern physical modeling synthesizers.
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 virtual analog synthesizer/vocoder from Korg featuring DSP analog modelling. The synthesizer is built in such a way that it is essentially a Korg MS-2000 with 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 synthesizer was an eight-voice polyphonic hybrid digital-analog synthesizer 61-note keyboard instrument released in 1985. By the time of its launch Korg had already begun a common trend in 1980s synthesizer design: using numerical codes to access or change parameters with the Korg Poly-61, which was widely regarded as the company's first 'knobless' synthesizer. This was a move away from the heavily laden, complex control panels of earlier designs.
The Korg Prophecy is considered one of the earliest (mid-nineties) "virtual analog" synthesizers, although its synthesis capabilities went beyond many of its VA contemporaries.
The Korg Trinity is a synthesizer music workstation released by Korg in 1995. It was also the first workstation to offer modular expansion for not only sounds, but also studio-grade feature such as SCSI, ADAT, various sound engine processors, audio recording capability, and more. It was considered one of the most comprehensive music workstations, in term of features, at the time.
The Korg Polysix(PS-6) is a six-voice programmable polyphonic analog synthesizer released by Korg in 1981.
The Korg MS2000 is a virtual analog synthesizer produced by the Japanese electronic musical instrument manufacturer Korg.
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.
A synthesizer is an electronic musical instrument that generates audio signals. Synthesizers generate audio through methods including subtractive synthesis, additive synthesis, and frequency modulation synthesis. These sounds may be shaped and modulated by components such as filters, envelopes, and low-frequency oscillators. Synthesizers are typically sequenced, controlled by software or instruments via MIDI, or played with keyboards or other controllers.
Casio's SD Synthesizers were a late-1980s line of hybrid digital-analog synthesizers featuring a resonant analog filter. SD synthesis was very similar to traditional DCO-analog synthesis, with the main difference being that some of the SD digital waveforms' harmonic spectrums changed temporally, or dynamically in relation to the amplitude envelope. SD synthesis is used in six Casio synthesizers and home keyboards released in 1987 and produced until 1991, when Casio exited the synthesizer market completely and focused solely on pure consumer keyboards. Due to some programming limitations plus Casio's poor marketing, the SD synths never gained wide popularity and are now fairly rare in the second-hand marketplace. There still exists a small but devoted fanbase who insist that SD synthesis, particularly as expanded in the high-end model HT-6000, was overlooked and highly underrated.
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 Kronos is a music workstation manufactured by Korg that combines nine different synthesizer sound engines with a sequencer, digital recorder, effects, a color touchscreen display and a keyboard. Korg's latest flagship synthesizer series at the time of its announcement, the Kronos series was announced at the winter NAMM Show in Anaheim, California in January 2011.
The Korg Z1 is a physical modelling sound synthesiser released in 1997. Touted as a polyphonic Prophecy, the Z1 implements 13 synthesis types, all derived from the original OASYS synthesizer.
