VCO 2 PWM (Pulse Width Modulation) Parameters
• The PWM parameters are not available when the
is set to "Triangle" or "Sine."
• VCO 2 PWM SRC (Pulse Width Modulation Source)
Settings: Fixed, PEG, FEG, LFO 1, LFO 2,
LFO 2 Phase, LFO 2 Fast,
VCO 1
• Parameter settings in italics above can only be selected by using the DATA DEC/INC buttons,
or by holding [shift] on the computer keyboard and using the cursor keys.
With the exception of "VCO 1" (VCO 2 cannot be used to modulate itself!), these settings
are the same as those of
VCO 2 PWM DEPTH (Pulse Width Modulation Depth)
These parameters are the same as those of VCO 1.
• When the
is set to "Triangle" or "Sine," the VCO 2 PWM PW parameter has no
effect.
X-MOD Parameters
The X-MOD (cross-modulation) parameters are available only when the
set to "Triangle" or "Sine." Whereas the PWM parameters use a source to modulate the
pulse width of the oscillator, X-MOD is similar to FM in that it modulates the frequency of
the oscillator, generating a complex set of harmonics. The control source for the Depth of
the modulation can be selected from: PEG, FEG, LFO 1, or LFO 2. The actual modulator
for cross-modulation is fixed to VCO1.
• The harmonics that X-MOD generates are different from those of FM because of the method
used: FM modulates in a logarithmic fashion, while X-MOD modulates in a linear fashion.
• X-MOD SRC (Cross-modulation Depth Control Source)
Settings: Fixed, PEG, FEG, LFO 1, LFO 2
This determines the source wave which changes the Cross Modulation Depth over time.
When this is set to "Fixed," there is no change in modulation depth over time. This
parameter is available only when the
is set to "Triangle" or "Sine."
• X-MOD DEPTH
Range: -64 ... +63
This determines the amount of depth of the cross-modulation of the VCO 2. Higher (pos-
itive) values produce a deeper modulation of the frequency. This parameter is available
only when the
is set to "Triangle" or "Sine."
