With a bold new approach that is at once both daring and familiar, RADIUS exceeds common analog expectations and rapidly takes off for uncharted territories. 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 heart of RADIUS beats with Korg's cutting-edge MMT (Multi Modeling Technology) synth engine, and borrows much of its modeling techniques from Korg's flagship OASYS – eliminating aliasing noise in even the highest frequencies and delivering clean, pure waveforms. RADIAS provides two oscillators for each timbre. Between them, they deliver not only modeled analog waveforms, but also formant waveforms, noise, ring modulation, sync, plus both classic and up-to-date PCM waveforms. When using the analog modeled waveforms, a variety of oscillator modulation algorithms – including pulse-width modulation, a massive Unison mode, Korg's proprietary VPM (Variable Phase Modulation) or cross modulation – can be used to create complex sounds, even from a single oscillator.
RADIUS provides a dual-filter structure, allowing the two filters to be used individually, side by side, or in series for maximum versatility. Filter 1 is highlighted by a continuously variable multi-mode filter, embracing Low Pass, High Pass and Band Pass modes – and new treatments in between. This dual filter arrangement provides a vast range of sounds that would be unimaginable from just a single filter, and opens up new sonic possibilities including some fantastic comb filtering.
Three Envelope Generators (EG) are used to apply time-varying changes to the pitch, filter cutoff, and amp level, as well as many other parameters. The classic and intuitive four-stage ADSR design has been enhanced with five different attack and release curves, allowing the EG contours to be crafted with new levels of precision and articulation. Two LFOs are available to apply cyclic changes to a host of synth parameters. Six LFO waveforms are provided, including the popular “Sample & Hold” stepped wave. Each waveform can be extensively modified via the Shape control, greatly expanding the versatility of the LFO section for creating highly complex types of modulation.
Adding Drive can produce the distinctive warmth of a true analog synthesizer and can also distort the sound intensely to generate new overtones. The amount of Drive is dependent on the level of each voice as it enters the mixer, so you can create nuances that cannot be achieved by an external effect unit. RADIUS offers eleven innovative types of Wave shaping – even recreating the shaping circuit can be placed in different locations in the signal chain, affecting the sound in very meaningful ways. An additional Punch Level setting emphasizes the attack portion of the sound, letting you create sounds with even more impact. Clearly, this is a radical new instrument that is not bound by conventions of the past.
