The Korg RADIAS keyboard is a 49-key, 24-voice polyphonic programmable modeling synthesizer and 16-band vocoder instrument, based on the proprietary MMT modeling technology sound engine. The synthesizer offers a variety of synthesis algorithms together with multiple effects, advanced comb filter and wave shaping features, modulation sequencing, and formant-motion vocoding.
The RADIAS offers an innovative, custom-configurable design with a control module that can be used independently or teamed with the unique dedicated keyboard, creating an integrated performance instrument offering classic, current and futuristic sounds accessible from a familiar, old-school, knobs-and-buttons programming interface.
