Value
Explanation
Value [-] [+]
T :
Sawtooth wave
SAW
This waveform contains a sine wave fundamental plus a fixed proportion of sine wave
harmonics at all integer multiples of that fundamental.
U :
Square wave
SQR
This waveform contains a sine wave fundamental plus a fixed proportion of sine wave
harmonics at odd-numbered multiples of that fundamental.
V :
Asymmetrical square wave
PW-SQR
The overtone structure of this waveform will vary significantly depending on the width of the
upper portion of the waveform (Pulse Width).
S :
Triangle wave
This waveform contains a sine wave fundamental plus a fixed proportion of sine wave
TRI
harmonics at odd-numbered multiples of that fundamental. It produces an uncolored sound
with fewer overtones than a square wave.
R :
Sine wave
SIN
This is a sine wave. This is a waveform that produces just a single frequency; it is the basis of all sound.
0oct, 1oct, 2oct, 3oct,
Specifies the range of the Pitch parameter in units of an octave.
4oct
Adjusts the pitch in semitone steps.
-48–0–+48
The range of this setting depends on the Pitch Range setting.
-50–0–+50 Adjusts the pitch in steps of one cent.
Specifies the amount (depth) of LFO applied to PW (Pulse Width). If the Waveform has selected
V (PW-SQR), you can use this slider to specify the amount of LFO modulation applied to PW
0–127
(pulse width).
* This is valid if LFO PW Dst (LFO Pulse width Destination) is set to OSC1+2 or OSC1.
Specifies the pulse width.
If the Waveform has selected V (PW-SQR), you can use this slider to specify the width of the
0–127 upper portion of the square wave (the pulse width).
Decreasing the value will decrease the width, approaching a square wave (pulse width = 50%).
Increasing the value will increase the width, producing a distinctive sound.
0–127 Specifies the amount by which the A-OSC2/AUX waveform modulates the A-OSC1 frequency.
Produces a metallic tonal character by multiplying A-OSC1 and A-OSC2/AUX.
OFF, ON
A-OSC2/AUX
Selects the waveform (A-OSC2/AUX) that will be the source of Cross Mod/Ring Sw modulation.
OSC2
* If Mod Src is set to AUX, the sound of AUX (White Noise, Pink Noise, Digital Part, MIC) will not
AUX
be heard even if you raise AUX Level. AUX will be used only as a modulation source signal.

OFF, ON If this is ON, the phase of OSC1 and OSC2 is synchronized when you play the keyboard.
0oct, 1oct, 2oct, 3oct,
Specifies the range of the Pitch parameter in units of an octave.
4oct
Adjusts the pitch in semitone steps.
