Product Description
Korg RADIAS keyboard is a 49-key, 24-voice polyphonic programmable modeling synthesizer16-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 filterwave shaping features, modulation sequencing,formant-motion vocoding.
The RADIAS offers an innovative, custom-configurable design with a control module that can be used independentlyteamed with the unique dedicated keyboard, creating an integrated performance instrument offering classic, currentfuturistic sounds accessible from a familiar, old-school, knobs-and-buttons programming interface.
49-key keyboard
Two oscillators per timbre, which share the low-aliasing design of Korg´s OASYS
Modeled analog, formantKorg´s classic DWGS waveforms, PCM playback, as well as ring modulationsync
Dual multimode filters, three envelopes, two LFOs, three modulation sequencers Six virtual patches (for freely connecting any of 11 modulation sources to any of 15 destinations)
2-band EQ, Drive, 11 types of Wave Shaping
Punch parameter emphasizes the attack portion of the sound
Each Program contains an arpeggiator with six pattern typestwo Step Sequencers
16-band vocoder section, each with levelpan controls
Formant Motion function records up to 7.5 seconds of incoming formant information per Program so users can recreate vocoder effects even when no microphone is present
Headset microphone included
Two effects for each timbre, plus a program-wide master effect.
30 included effects types range from delay, chorusreverb, to compressortalking modulator
Tone Generator
MMT (Multiple Modeling Technology) synthesis
Maximum Polyphony - 24 voices
Varies depending on the parameters that make up the sound.
