Below and to the centre is the Frequency Skew control, marked F.
Skew. When set to 12 O’Clock and with no modulation of the F. SKew
CV the cutoff of the left and right filters will be even. Turning the
control anti clockwise will increase the cutoff frequency of the Left
filter and decrease the Right, around the base point set by the Stereo
Frequency control. Conversely turning clockwise will decrease the
cutoff on the Left and increase it on the Right.
To the right is the Resonance Skew control, marked R. Skew. Like the
Frequency Skew control this skews the resonance amount around the
point set by the Stereo Resonance control, moving anti clockwise
increasing the amount of resonance on the Left and decreasing the
amount on the right and vice versa.
The collection of three black capped controls to the bottom left of the
control section are FM1 CV amount, FM2 CV amount and Frequency
Skew CV Amount, marked Skew. These control the amount of CV
modulation from the CV inputs below them. FM1 is a unipolar CV input
which modulates the Stereo Frequency. FM2 also modulates Stereo
Frequency but the control is an attenuvertor, so the control is off at
the 12 O’Clock position, increases when turned to the right and applies
an increasing amount of a negative version of the voltage when turned
to the left. The Skew CV also goes through an attenuvertor, this gives
voltage control over the Frequency Skew parameter.
Finally, the Res CV and Res Skew CV controls and inputs round out the
control section. As expected these provide CV control over the
Resonance and Resonance Skew parameters, respectively.
