Carrier/Modulator
Waveform [2] knob (on the top
screen only)
SINE, TRI,
SQR, SAW
This sets the waveform.
Coarse Tune PITCH -24–+24 Specifies the pitch in semitone steps (maximum ±2 octaves).
Fine Tune SHIFT+PITCH -50–+50 Specifies the pitch in cents (maximum ±50 cents).
Ratio TIMBRE 1.0–16.0 Sets the frequency ratio between the carrier and modulator.
Ratio Fine
SHIFT+TIMBRE -50–+50 Sets the frequency ratio between the carrier and modulator
in smaller steps.
Mod Env Atk [OSC 1] slider 0–1023 Sets the attack time of the modulation envelope.
Mod Env Dcy/Rel
[OSC 2] slider 0–1023 Sets the decay and release times of the modulation
envelope.
Mod Env Sus [OSC 3] slider 0–511 Sets the sustain level of the modulation envelope.
Mod Depth
[OSC 4] slider 0–63 Sets the intensity of the modulation envelope.
Larger values produce a greater change with the
modulation envelope.
Carrier/Modulator Pulse
Width
- 0–63 This effect changes the duty ratio of the pulse width to alter
the waveform.
You can use this effect with other waveforms besides SQR
(square wave).
* A value of zero results in a 50:50% duty ratio.
Carrier/Modulator PWM
Depth
- 0–63 Sets how much the LFO is applied (depth) to the PW (pulse
width).
The pulse width is modulated according to the LFO settings.
Carrier/Modulator Fat
- 0–63 Distorts the waveform and adds a frequency component
one octave lower than the original waveform.
