When you move a controller, the corresponding parameter is shown in the screen
(the value changes in tandem with the controller).
If you move the controller while holding down the [Exit] button, the parameter is
displayed without changing its value; this lets you check the current value.
* Digital parts do not use the A-OSC2 and MIXER sections.
DIGITAL PART
Controller Explanation
Select [01]–[04]
buttons
Select the part that is edited by panel operations.
On [01]–[04]
buttons
Select the part that is played from the keyboard.
[Unison] button Selects unison.
PARTIAL
Controller Explanation
Select [01]–[03]
buttons
Select the partial that is edited by panel operations.
On [01]–[03]
buttons
Select the partials that produce sound.
LFO
Controller Explanation
Wave knob
Selects the LFO waveform.
S (Triangle wave), R (Sine wave), T (Sawtooth wave), U (Square wave),
W (Sample and Hold), RND (Random wave)
[Rate] knob
Determines the speed of the LFO modulation.
* If the [Tempo Sync] button is on, you can specify the LFO modulation
speed in terms of a note value relative to the tempo.
[Select] button Not used with digital parts.
[Tempo Sync]
button
Synchronizes the LFO modulation speed to the tempo.
[Fade Time] slider
Specifies the time from when the tone
sounds until the LFO reaches its maximum
amplitude.
[Pitch Depth] slider
Allows the LFO to modulate the pitch of the partial, producing a vibrato
effect.
[Filter Depth] slider
Allows the LFO to modulate the FILTER CUTOFF (cutoff frequency),
producing a wah effect.
[Amp Depth] slider
Allows the LFO to modulate the AMP LEVEL (volume), producing a tremolo
effect.
D-OSC
Controller Explanation
Wave knob
Selects the oscillator waveform.
T (Sawtooth wave), U (Square wave), V (Asymmetrical square wave),
S (Triangle wave), R (Sine wave),
Variation (Press the [Variation] button and use the [-] [+] buttons to select
the variation waveform.)
[Variation] button Selects the variation waveform as the waveform of the oscillator.
[PWM] slider
When V (asymmetrical square wave) is selected as the oscillator
waveform
Specifies the amount of LFO modulation applied to PW.
[PW] slider
When V (asymmetrical square wave) is selected as the oscillator
waveform
Specifies the pulse width.
When SuperSaw is selected as the oscillator waveform
Specifies the detune.
[Pitch] knob Specifies the oscillator pitch.
[Fine] knob Fine adjustment of the oscillator pitch.
Controller Explanation
[Cross Mod] knob Not used with digital parts.
[Ring Mod] button
Produces a more complex waveform by multiplying Partial 1’s OSC by Partial
2’s OSC.
[Mod Source]
button
Not used with digital parts.
PITCH ENV
Controller Explanation
[Depth] knob Specifies the direction and amount of the pitch change.
[Select] button Not used with digital parts.
[A] slider These have the same operation as the PITCH ENV [A] [D] sliders for an analog
part. [D] slider
FILTER
Controller Explanation
[HPF] knob Specifies the cutoff frequency of the high-pass filter.
[Drive] knob Not used with digital parts.
Filter type select
knob
Selects the filter type.
The indicator shows the slope of the filter.
-12 dB/oct (unlit), -24 dB/oct (lit)
[Variation] button Selects the variation type as the type of filter.
[Cutoff] knob Specifies the cutoff frequency.
[Resonance] knob Specifies the resonance.
[Key Follow] knob Allows the filter cutoff frequency to vary according to the key that you play.
[ENV Depth] knob Specifies the direction and amount of the change in cutoff frequency.
[A] slider
These have the same operation as the FILTER [A] [D] [S] [R] sliders for an
analog part.
[D] slider
[S] slider
[R] slider
AMP
Controller Explanation
[Level] knob Specifies the AMP Level.
[A] slider
These have the same operation as the AMP [A] [D] [S] [R] sliders for an analog
part.
[D] slider
[S] slider
[R] slider

Controller Explanation
[TFX 1/2 Select]
knob
Selects the TFX1/2 effect type.
[TFX 1/2 CTRL]
knob
Globally controls TFX1/2.
Global control is a function that lets you use a single knob to control
multiple parameters that make up the effect.
[TFX 1/2 On] button Turns TFX1/2 on/off.
[Reverb] knob Specifies the volume of reverb.
[Delay] knob Specifies the volume of delay.
Delay [Time] knob Specifies the delay time.
[Part MFX SW]
button
Turns the Part MFX on/off.
[Tempo Sync]
button
Synchronizes the Part MFX and delay to the tempo.
If this is “off,” the Tempo Sync setting of each effect is used.
& For details on the parameters, refer to “Parameter Guide (English)” (PDF).
