Software versions of Korg’s classic and ever-popular MS-20, Polysix, and WAVESTATION, plus a dedicated controller for the MS-20 software.

The MS-20 and Polysix use Korg’s proprietary CMT (Component Modeling Technology) to precisely model the electronic circuitry of the original analog instruments, capturing the exact sound and parameter response of the originals.

In addition to replicating the original sounds, the MS-20 and Polysix software synthesizers also provide a wide range of new functionality for contemporary sound creation, such as 32-voice polyphony (max), up to 16-voice unison settings, and freely assignable external modulation settings.

Create completely new sounds using Legacy Cell, a combination structure that lets you freely combine the MS-20 and Polysix software synthesizers together with insert/master effects and use them as a single instrument.

The WAVESTATION software synthesizer encompasses all the waveforms, effects, and sound programs of the WAVESTATION series, delivering perfect simulation of the original sound, along with compatibility with user/third-party files (in .SYX format). It features a new graphical user interface that provides a revolutionary leap in ease of operation.

Also included is a special edition MS-20 USB-MIDI controller dedicated for use with the MS-20 software. The controller provides all the knobs, controls and patch points of the original unit at 84% of the original size, as well as providing a velocity-sensitive mini-keyboard.

Plug-in effects are also provided - the MS-20FX lets you run audio through the MS-20 audio input and filters, and the MDE-X plug-in lets you use any of the Legacy Cell nineteen different effects.

"KORG Legacy Collection" resurrects Korg’s legendary synthesizers
The KORG Legacy Collection is the ultimate virtual instrument pack, consisting of software versions of the MS-20 and Polysix analog synthesizers, and the WAVESTATION advanced vector synthesizer, together with a dedicated MS-20 Controller that faithfully replicates the original MS-20 at 84% of the original size.
Perennially popular and hard to find in their hardware formats, these legendary synths are now resurrected for use in your computer as state-of-the-art software synthesizers. Our CMT electronic circuit modeling technology delivers stunningly accurate reproductions of the analog MS-20 and Polysix, and the groundbreaking Legacy Cell combination structure produces beefy and complex new timbres that far surpass the original models. The WAVESTATION is brought into the modern age, answering the requests of thousands of fans of that much beloved instrument.


Newly-developed CMT technology completely reproduces the circuitry of the original synthesizer
The MS-20 and Polysix software synthesizers use Korg’s newly developed CMT (Component Modeling Technology). In contrast to existing approaches that simply simulate the output sound, CMT digitally models the transistors, condensers, resistors, and other parts used in the original hardware, and replicates the same circuitry as the original. The complex sound and parameter response can be perfectly reproduced, delivering all the power and subtlety that up until now only true analog synthesis could provide.


MS-20 software synthesizer
Since the MS-20 went on sale in 1978, this semi-modular monophonic synthesizer has enjoyed unbroken popularity for its thick and solid sound, aggressive analog filters, and inexhaustible potential for creative patching.
With two oscillators (which can be ring-modulated), high-pass/low-pass self-oscillating filters with unique distortion, and a patch section with an external signal processor that can accommodate external audio input, the MS-20 software synthesizer provides a complete simulation of its legendary original. In addition, it gives you modern advantages such as up to 32 voices of polyphony and up to 16-voice unison (with detune/spread function). Flexible external modulation settings and MIDI clock synchronization have also been added, giving you even greater creative potential.
Along with the provided Programs, a number of templates are included providing instant setups for running audio through the filter and other commonly-used functions.


MS-20 Controller Included
Also included is a USB-MIDI controller that reproduces the original MS-20 at 84% size, with the addition of a velocity-sensitive mini-keyboard. From the shape of the knobs, the way in which the LEDs blink, the panel silk-screening, right down to the color of the included patch cords, the MS-20 Controller perfectly replicates the original MS-20. Simply connect it to your computer via USB, then turn the knobs and use the patching facilities for complete realtime control of the MS-20 software.


Polysix software synthesizer
The Polysix programmable six-voice polyphonic analog synthesizer was introduced in 1981. With a surprisingly full-sounding voice structure, chorus/phase/ensemble effects and performance functions such as chord memory, arpeggiator, and unison the Polysix became a world-wide hit. Its distinctive string and pad sounds are often heard to this day.
In addition to faithfully replicating the sound of the original, the Polysix software synthesizer also adds enhancements such as 32-voice polyphony (max), up to 16-voice unison (with detune/spread function), flexible external modulation settings, MIDI clock synchronization, and a spread function that adjusts the spaciousness of the effects --- functionality that brings this classic synthesizer up to date for modern music production.
The interface provides reorganized knobs and switches that resurrect the Polysix in a contemporary "rack-mountable" form for even more intuitive operation and sound-creating versatility.


Legacy Cell --- use the MS-20, Polysix, and effects as a single software synthesizer
Legacy Cell is a completely new idea not available on any previous software synthesizer. It’s a revolutionary "combination structure" that lets you use one of five different combinations of synthesizers (MS-20 Polysix, 2 x MS-20, 2 x Polysix, 1 x MS-20, or 1 x Polysix) plus two insert effects and two master effects --- all as a single software synthesizer that delivers powerful new sounds and textures!
You can freely specify key and velocity layers/splits and velocity curves to switch between the combination of synthesizers. For the insert and master effects, you can choose from 19 different effect algorithms that Korg has developed and refined through its many years of technology. There’s also a controller section where you can assign any synthesizer or effect parameter, giving you virtually infinite possibilities for music production and performance.
Legacy Cell provides 256 different performance programs including controller assignments. The programs include spacious pads that shift over time thanks to the advanced modulations possibilities, fat sounds that take advantage of the new Unison parameter, and phrase-type programs that combine the MS-20 and Polysix software synthesizers to play a kick, bass, and pad from a single key. Korg’s highly respected sound designers have created programs that match classic Korg sounds to today’s music scene.
Legacy Cell has built-in native support for the separately sold microKONTROL MIDI Studio Controller; simply connect the microKONTROL via USB and you can completely control every aspect of the software using the many sliders, encoders and pads and more.

WAVESTATION software synthesizer
The WAVESTATION synthesizer appeared in 1990 with its new "advanced vector synthesis system" which combined and shifted between multiple complex waveforms. It received numerous awards from around the world, including U.S. Keyboard magazine’s "Hardware Innovation of the Year." The user could operate a joystick to "mix" or "morph" between fou
