a nonlinear process, the incoming signal is reshaped to a greater or lesser degree depending
upon its level at each moment in time.
Incoming signals are first clipped to the dB level set by the Drive control. The meter on the right
side of the display shows how much Saturator is influencing the signal.
Signal shaping has six fixed modes: Analog Clip, Soft Sine, Medium Curve, Hard Curve, Sinoid
Fold and Digital Clip. There is also the flexible Waveshaper mode, featuring six adjustable
waveshaping parameters.
In the Analog Clip and Digital Clip modes, the signal is clipped completely and immediately.
Soft Sine, Medium Curve and Hard Curve modes soften signal clipping to varying degrees.
Sinoid Fold mode can be good for special effects.
The most dramatic effects can be created by selecting the Waveshaper curve, which has its own
dedicated set of controls. To access these six parameter fields, unfold the Saturator window by
toggling the button in its title bar.
The Waveshaper mode’s six additional parameters are: Drive, Lin, Curve, Damp, Depth and
Period.
•Drive determines how much the input signal will be influenced by the Waveshaper param-
eters. Setting Drive to zero will negate the effect entirely.
•Lin works together with the Curve and Depth parameters to alter the linear portion of the
shaping curve.
•Curve adds mostly third-order harmonics to the input signal.
•Damp flattens any signal near the grid’s origin. It behaves like an ultra-fast noise gate.
•Depth controls the amplitude of a sine wave that is superimposed onto the distortion curve.
•Period determines the density of ripples in the superimposed sine wave.
The DC button activates a DC filter at Saturator’s input stage. This is mainly useful for removing
DC offsets from audio material that contains them.
Activating the Color button enables two filters. The first of these, controlled with the Base control,
dictates how much the effect will be reduced or increased for very low frequencies. The second
