Parameter guide

PROG P2: OSC/Pitch

These pages control the first and most basic elements of
RADIAS program’s sounds: the waveform that the
oscillators play, the pitch, and output level at which it plays
them. For instance, you can:

• Select the oscillator 1 waveform and modulation type,

and specify waveform parameters according to the
modulation type.

• Select the oscillator 2 waveform and modulation type,

and specify the pitch.

• Specify the output level of each oscillator, including the

noise generator.

• Specify the oscillator pitch.

• Specify the vibrato effect applied by the +Y axis of the

joystick.

• Specify the pitch bend range.

• Specify the portamento.

2–1: OSC Basic

These parameters affect the waveform and output of each
oscillator. You can create complex waveforms by using the
two oscillators 1 and 2.

2–1a: OSC1

Waveform (Oscillator1 Waveform)

[Saw, Square, Tri, Sine, Formant, Noise, DWGS,

AudioIn]

Selects the waveform of oscillator 1. The parameters
controlled by the

Control1

knob and

Control2

knob will be

different based on the waveform you select here and on the

OSC Mod

setting.

Saw:

This sawtooth wave is appropriate for creating a wide

range of sounds typical of analog synthesizers, including
basses and pads.

Square:

This is a pulse wave suitable for electronic sounds

and wind instruments. By adjusting the pulse width you can
produce sounds reminiscent of clavi or sax.

Tri:

Triangle wave has fewer overtones than sawtooth wave

or square wave, and is suitable for mild tone such as bass or
pads.

Sine:

Sine wave is a mild tone that contains only the

fundamental frequency with no overtones.

Formant:

The formant waveform has a tonal character

reminiscent of a human voice.

Noise:

Generates noise.

Control1

boosts the pitched

component within the noise, and

Control2

adjusts the

brightness.

DWGS:

This provides various DWGS waveforms taken

from acoustic instruments and digital synthesizers. You can
choose one of 64 different DWGS waveforms.

AudioIn:

This lets you use the input source specified by

Audio In

as the oscillator output.

Audio In

[Audio Input Source, AUX Bus Source]

Selects the audio input source. This is valid only if

Waveform

is set to

AudioIn

. Use

Control1 Gain

to adjust

the input volume, and

Control2 Balance

to adjust the

balance.

Audio Input Source:

The audio input source will be the

signal from the input jack selected by

Audio Inputs (Send

to RADIAS)

(Program 1-1c). If the P1: Program Basic page

Unison

parameter is

Off

, the signal will be mixed to mono.

AUX Bus Source:

The audio input source will be the signal

from the AUX bus selected by

AUX Bus (Send to RADIAS)

Note:

In order to use the AUX buses, you must first assign

audio signals to the AUX buses using the audio in post-IFX
AUX setting (Program 8-2) or the drum track AUX setting
(Program 1-4c

☞

“AUX Bus (Send to RADIAS)” on page 26).

If the P1: Program Basic page

Unison

setting is

Off

, the

signal will be mixed to mono.

OSC Mod (Oscillator Modulation Type)

[Waveform, Cross, Unison, VPM]

Selects the modulation type for oscillator 1.

The maximum number of voices will change
depending on the combination of

Waveform

and

OSC

Mod

settings.

You can’t apply modulation if

Waveform

is set to

Formant

Noise

DWGS

, or

AudioIn

. This field will be

shown as Waveform.

Waveform (Waveform Modulation):

Use

Control1

modify the waveform.

Cross (Cross Modulation):

Cross Modulation uses the

output waveform of oscillator 2 (the modulator) to
modulate the frequency of oscillator 1 (the carrier) at high
speed to produce a modulated sound. The waveform
selected by

Waveform

will be the carrier.

Unison:

Unison skews the pitch of five oscillators within a

single oscillator and outputs them together to create a richer
sound.
