[ENV DEPTH]
Here’s how you can adjust the depth of the Pitch Envelope. The
more the slider is moved upwards, the greater the change is. Moving
the slider below the center position inverts the waveform, and the
change in the opposite direction increases. At the center position, the
pitch envelope does not create any change in pitch.

Changing the Pulse Width of a
Square Wave Periodically (PWM)
[PWM (LFO 2)]
Adding an LFO to the pulse width (of a square wave), which results
in a cyclic change in the square wave’s pulse width, is called

Pulse
Width Modulation (PWM)
. The amount of PWM applied is set with
[PWM (LFO 2)]. The change in the pulse width increases as the slider
is moved upwards, resulting in a tone with greater breadth that
seems to spread out. The speed of modulation is set by turning the
“LFO 2” [RATE] knob (p. 60).

selected with [WAVE] and LFO 2 is on.

• The ring modulation effect is only applied to OSC 1; the OSC 2
tone is not changed. If the ring modulator effect is not
sufficiently evident, raise [BALANCE] (toward the OSC 1 end).
Moving [BALANCE] allows you to alter the ratio of the OSC 1
sound (to which ring modulation is applied), and the normal
OSC 2 sound.

What is a Ring Modulator?
The Ring Modulator combines the waves from OSC 1 and OSC

“cross” of the two signals producing tones with numerous
harmonics (non-integer harmonics) not included in either of the
original waveforms.

“cross” of the two signals producing tones with numerous
harmonics (non-integer harmonics) not included in either of the
original waveforms.
As the pitch difference between the two waveforms changes the
harmonic structure, the result will be an unpitched metallic
sound. This function is suitable for creating metallic sounds
such as bells.
