SATURATION for Added Grit and Dirt

In serial filter modes, the SATURA-
TION unit is located between the 
filters. This configuration gives you 
the option of first filtering the 
oscillator signal in the conven-
tional manner, then distorting it, 
and finally sending the distorted 
signal to a second filter, where it 
can be processed again as you see 
fit.

Next to serving as a volume con-
trol for the OSCILLATOR section, in 
the right half of its control range, 
the OSC VOL knob lets you control 
the gain level of the distortion 
module (SATURATION) within a 
wide range of 12 decibels, , without 
increasing the volume level. At 24 
decibels, the control range of the 
"Digital" SATURATION Curve is 
even greater. The OSC VOL knob 
retains its function as a volume 
control in Input mode as well as in 
Vocoder mode.

The Shaper’s saturation response 
differs from that of the other SAT-
URATION Curves. Its characteristic 
curve is a sine wave with several 
cycles. The Shaper lets you radically 
bend signals, whereby the results 
are at times reminiscent of the 
spectra of linear frequency modu-
lation. The response of the Shaper 
depends largely on the input sig-
nal. This means that the Filter-1 
settings have a profound impact 
on the outcome. You should use 
Filter-2 independently of Filter-1 in 
order to further process the raw 
output signal of the Shaper. As is 
the case with the other SATURA-
TION Curves, the OSC VOL knob is 
used to tweak the characteristics 
that shape its timbre . In particular 
in the case of the Shaper, this knob 
influences the complexity of the 
generated sound to a considerable 
degree.
