Past, present, and future come together in one thrilling instrument that is every synthesist’s dream. With a bold new approach that is at once both daring and familiar, RADIAS exceeds common analog expectations and rapidly takes off for uncharted territories.

Extended information

Based on Korg’s cutting-edge MMT engine, this 24-voice synthesizer offers a variety of synthesis algorithms together with multiple effects, new comb filter and wave shaping features, modulation sequencing, as well as new formant-motion vocoding.

RADIAS offers an innovative design that can be custom configured to suit your set-up. The control module can be used independently or teamed with the unique dedicated keyboard, creating a seamlessly integrated instrument that delivers the sounds of the future – today.

New shape, new possibilities - You can choose the RADIAS model that’s right for you; RADIAS consists of a sound module section plus a dedicated 49-note, velocity-sensing keyboard with traditional Pitch and Mod wheels. The panel layout features a lavish complement of knobs and buttons, letting you enjoy the same intuitive feel of creating sounds as on an analog synthesizer. The unique design allows the knob-laden control module to pivot up or down, and even move to the side to accommodate a laptop computer, ElecTribe, KAOSS Pad or other audio unit. RADIAS•R is the sound module by itself, which can be used both as a rackmount or tabletop synthesizer.
