Operation

Editing a program

In the PROG P0: Play page, you can select and play RADIAS
programs, use the control surface to perform quick editing,
and adjust the KARMA settings in the same way as for EDS
programs. In other pages, you can make more detailed edits
to the sound.

Basic settings for the program

To edit a RADIAS program, you’ll start in the PROG P1-1:
Program Basic page, where you can specify settings such as
scale type and audio input source.
Here we’ll explain how to make a RADIAS program play
monophonically.

Voice Assign Mode

1. Set the “Voice Assign Mode” to Mono.
Voice Assign Mode

specifies how the oscillators will

produce sound.
With the Mono setting, only one note will be heard even if
you play a chord on the keyboard. This setting is suitable if
you’re performing a synth bass, synth lead, or other solo
instrument sound.

2. Set “Trigger Mode” to Multi.
Trigger Mode

specifies how the sound will be triggered.

With the Multi setting, the sound is retriggered each time
you play a note.

3. Set “Priority” to Last.

With the Last setting, priority will be given to sounding the
last-played note if you’ve held down two or more keys
simultaneously.

4. Set “Unison” On (checked).
Unison

selects whether multiple voices will be sounded in

unison when you play a single note.
Note: If you want to produce a richer sound, turn

Unison

so that multiple voices will be “stacked.” The

Number of

Voices

specifies the number of voices that will be stacked.

5. Use “Number of Voices” to specify the number of

voices that you want to sound simultaneously.

6. Use “Detune [cents]” to specify the amount of detuning

(pitch difference) between the voices that are sounded
simultaneously.

The number of simultaneously-sounded voices specified by

Number of Voices

will be equally spread apart in pitch by

the specified

Detune [cents]

amount.

7. Use “Spread” to specify the stereo position of the

simultaneously-sounded voices.

The simultaneously-sounded voices specified by

Number of

Voices

will be evenly spread across the stereo field

according to the

Spread

setting.

Oscillators

RADIAS programs consist of three oscillators: oscillator 1,
oscillator 2, and a noise generator.
Here’s how to select the oscillator waveform and adjust the
output level.

Selecting the waveform

OSC1 (Oscillator 1)

1. Use the “Waveform” to select the waveform for

oscillator 1.

You can choose one of nine different waveforms, including
an external audio input (Audio In).

2. Use the “OSC Mod” to select the type of modulation

being applied to oscillator 1.

You can choose one of four modulation types.

If you’ve selected Formant, Noise, DWGS, or
AudioIn as the waveform, the only available
modulation type will be Waveform (Waveform
modulation).

3. Use the “Control 1” and “Control 2” to specify the

waveform parameters.

The parameters that are controlled by the
