The compact, portable R3 was designed to bring the main feature set and sounds of the upscale RADIAS into an affordable and portable performance keyboard. The Multi Modeling Technology (MMT) synth engine in R3 is the same as featured in RADIAS, and borrows ultra low-aliasing modeling techniques from the OASYS. An R3 Program consists of two complete Timbres – each is a complete synth sound including dual insert effects. The Program itself offers a master effect, plus an 8-step arpeggiator.
Korg R3 Features:
- 37-key synth with Multi Modeling Technology (MMT) synth engine from RADIAS
- 128 Programs, all organized by sound category for fast access
- Two oscillators combine to offer analog-modeled waves, PCM waves, noise, ring mod, and more
- Waveform modulation, Variable Phase Modulation (VPM), Unison voice thickening, PWM, and cross-mod expand the sonic palette
- Dual Filters can run in series, parallel, or side by side
- Two LFOs and three ADSR envelopes shape the sound and add cyclic motion to nearly any voice parameter
- Modulation Sequencers (one per Timbre) provide discrete values to a modulation parameter that change over time
- Audio inputs allow any audio signal to be gated and filtered using the internal synthesis and effects
