Introduction; Overview; Program Structure; Synth Programs - Korg EXB-RADIAS for M3 Owner's Manual

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 access
the 128 RADIAS programs in program bank INT–F. You'll
also be able to save original RADIAS programs you've
created to bank INT–F or to any other user banks that
you've designated as RADIAS type banks.
In Sequencer Mode or in Combi Mode, up to four RADIAS
programs can be assigned to individual MIDI tracks in a
song or to timbres in a combination, allowing you to create
combinations or songs that use RADIAS-based programs in
conjunction with EDS or GM programs.

Program structure

RADIAS programs can be either synth programs that are
based on MMT synthesis, 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 the 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 audio 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 the basic analog synthesizer waveforms
such for even more variety.
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.
