Korg RADIAS

The Korg RADIAS is a virtual analog synthesizer and Vocoder, released by Korg in 2006. The RADIAS' MMT (Multiple Modelling Technology) 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 (both digital and analog), though stays away from trying to emulate the Korg M1 and the Korg Wavestation, (these synthesizers used Pulse-code modulation, Sample-based synthesis and Wave sequencing/vector synthesis respectively, something that MMT does not emulate). As well as using the in-built waveforms (digital & analog emulations) 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 (filters / pitch envelopes etc.). The RADIAS has a comprehensive matrix modulation specification and to further enhance a sound the 'Wave Shaper' module allows for various sound distortion effects.

A 16-band vocoder with Formant Shift function is also available.

RADIAS also takes advantage of KKS Korg Komponent System which allows the user to detach the RADIAS-R module from the dedicated RADIAS-KB keyboard. The RADIAS-R module could be bought separately but the keyboard could not. The RADIAS-R module can be installed on the M3-73 or M3-88 and played simultaneously with the Korg M3 module using the M3's keyboard.
