Program Features; Step Sequencer - Korg Radias Owner's Manual

Overview
The RADIAS Synthesizer/Vocoder is based on Korg's powerful Multiple Modeling Technology (MMT). It
provides an extensive array of cutting-edge synthesis tools and techniques to satisfy the demanding musi-
cian, producer or sound designer. The main sound parameters can be edited directly from the front panel.
Equipped with 39 knobs, 47 buttons, 16 multi-function keys, a value knob and an informative backlit LCD
screen, RADIAS makes it easy to modify the sound as you perform, and to enjoy a versatile range of realtime
editing possibilities.

Program Features:

Structure
The RADIAS contains 256 user-editable Program locations. Each program consists of up to four timbres, let-
ting you easily create incredibly rich sounds. You can zone each timbre to a specific range of keys, and play
them all from the keyboard, or individual Timbres can be played by the arpeggiator or one of the step se-
quencers. Additionally, each timbre can be assigned to a specific MIDI channel for four-part multitimbral
operation.
Vocoder
The RADIAS features a sophisticated vocoder that can be used not just to simulate the classic vocoder
sounds of the past, but also to take advantage of advanced possibilities such as shifting the filter frequencies
of each band or adjusting their level and panning to create new and original vocoder sounds.
Korg's new Formant Motion function uses filter banks to analyze the input signal (the modulator), and
records up to seven seconds of formant motion data. By using the play back of this recorded formant motion
data, you can create complex moving (or even "talking") vocoder programs that don't require any mic input.
The RADIAS can hold sixteen sets of formant motion data in internal memory. A front panel [VOCODER]
button makes it easy to obtain vocoder sounds.
Audio input/envelope follower
Any audio signal plugged into the INPUT 1 and 2 jacks can be processed in the same way as the internal
waveforms, letting you use the RADIAS as an effect processor. The envelope of the audio input signal can
also be detected and used as a modulation source in the virtual patch, or used to trigger the sound generator
of the RADIAS.
Arpeggiator
The arpeggiator plays the notes you are holding down one at a time, in an up, down, alternating, random or
triggered chord fashion - six different types in all. The resolution, key window, swing, and octave range can
be set per program; the note, tie and off status can be set for each of the 16 steps, allowing you to create a
broad range of melodic and rhythmic patterns.

Step sequencer

Two step sequencers are built-in, allowing you to record simple patterns or phrases. For example you can
record a bass line and a drum pattern, and assign two timbres to play these parts, while you play the remain-
ing timbres from the keyboard. Each step sequencer is 32 steps long; however they can be combined to create
a single step sequencer that is 64 steps long.
