Radias

TheKorgRADIASis avirtual analog synthesizerandVocoder, released by Korg in 2006. The RADIAS' MMT (Multiple Modelling Technology)engine was based on theKorg OASYSsynthesizer module, providing for several different synthesis methods, two of which may be combined in a single voice e.g.phase distortion synthesiscan be combined withsubtractive synthesis. The different synthesis methods employed by MMT represent the majority of methods used historically in other Korg synthesizers:digital waveguide synthesisKorg first used in theKorg Z1andphase distortion synthesiswas first used in theKorg DS-8. This flexibility allows for very realistic emulations of past Korg synthesizers (both digital and analog), though stays away from trying to emulate theKorg M1and theKorg Wavestation, (these synthesizers usedPulse-code modulation,Sample-based synthesisand Wave sequencing/vector synthesisrespectively, 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.

Overview

Korg's Radias, introduced in 2006, is a modular synthesis system combining virtual analog and FM synthesis in a compact rackmount/tabletop format. This two-voice multitimbral instrument offers extensive modulation capabilities, a powerful vocoder, and the MS-20 filter emulation that Korg developed for their Legacy Collection software.

The instrument features two oscillators per voice, multiple filter types, three envelope generators, and two LFOs. The modulation matrix provides flexible routing of control sources. The Radias integrates with the M3 workstation as an expander module or operates independently.

The Radias demonstrates Korg's commitment to modular, expandable synthesis systems. Its combination of virtual analog warmth and digital precision appealed to electronic musicians seeking versatile sound design capabilities.
