The EXB-Radias Synth Expansion is a synthesizer and vocoder option board that uses Korg MMT (Multiple Modeling Technology) to provide a wide range of tonal variety and 24 voices of polyphony to the Korg M3 Music Workstation/Sampler series keyboards.
The Korg EXB Radias offers the same vocoder as the Radias, offering 16 bands with individual control over level and panning. Formant Motion records the formant of a sung or spoken phrase so it can be recreated anytime. All of Karma's generative features can be used with the Radias to provide even more options, including Radias Wave-Sequencing.
You can add an internal Radias analog modeling synthesizer sound generator board (one timbre, up to 24 voices), with on-screen integration of all its parameters and full integration with the M3's effects, control surface and KARMA (Kay Algorithmic Realtime Music Architecture) functionality.
The MMT-based synth engine features dual oscillators which combine to offer analog-modeled waves, DWGS (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 (individual for each oscillator). Filter1 features a resonant filter design covering 24 dB low pass, 12 dB low pass plus 12 dB high and band pass, with continuously variable "morphing" between these states. Filter2 offers 12dB versions of the low, high and band pass modes, plus a unique comb filter.
Two LFOs and three ADSR envelopes shape the sound and add cyclic motion to nearly any voice parameter. Three 16-step Modulation Sequencers provide discrete values to a modulation parameter that change over time, either in stepped or smooth motion, and can loop over and over.
Internal or external audio can be run through the EXB-Radias synth expansion board to be gated and filtered using the internal synthesis and effects. "Drive" adds analog warmth, Punch brings increased definition to the attack of a sound, and 12-types of Wave Shaping provides dramatic timbral shaping” even offering virtual "pick-up" response.
Up to four Radias programs can be assigned to timbres in a combination or MIDI tracks in a song, allowing you to create combinations or songs that use them in conjunction with other programs.
