Overview

The EXB-RADIAS is a synthesizer/vocoder option board
that uses Korg MMT (Multiple Modeling Technology) to
provide a wide range of tonal variety and 24 voices of
polyphony.
When the EXB-RADIAS is installed, you'll be able to use 128
RADIAS programs in program bank INT-F. You'll also be
able to save original RADIAS programs you've created in
bank INT-F or user banks that you've assigned as bank type
RADIAS.
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 the programs of banks INT-A–E, INT-G, and USER A–
G.

Program structure

RADIAS programs can be synth programs that are based
mainly on an oscillator algorithm, or vocoder programs that
use the vocoder function.

Synth programs

A synth program uses three oscillators (including a noise
generator) to produce waveforms which are then processed
by filters, amp, EGs, LFOs, and modulation sequencer to
create sounds with a wide range of expressive character.
Oscillators (OSC1, OSC2, NOISE)
Oscillator 1 (OSC1) lets you choose from eight types of
oscillator algorithm (ranging from basic analog synthesizer
waveforms such as sawtooth and triangle to DWGS digital
synthesizer waveforms), as well as the signals from the
AUDIO INPUT, S/P DIF, and EXB-FW (separately sold
option) jacks or signals from the AUX bus. You can also
apply cross modulation, unison, or VPM (Variable Phase
Modulation) to basic analog synthesizer waveforms such as
sawtooth or triangle wave.
Oscillator 2 (OSC2) lets you choose from four different
oscillator waves - sine, triangle, square, and sawtooth.
Oscillator 2 can be used as the modulating oscillator for the
sync modulation (SYNC) or ring modulation (RING) that
are such classic analog synthesizer techniques. The best
elements of SYNC and RING modulation can be combined
using a third option: RING SYNC.
The noise generator (NOISE) generates white noise. You can
use this for a variety of sound shaping situations, such as
