Controls for Filters A & B 
The following controls are identical
for both Filter A (left side, labeled in
red ) and Filter B (right side, labeled
in blue ):
[1] CUTOFF - Sets the cutoff
frequency of the filter. The
knob position is combined with
the FM1 and FM2 inputs.
[2] FM1 - Controls the amount of
attenuation for the FM1 input.
Although the FM1 input tracks
1V/Oct when this knob is fully
clockwise, each filter features
a dedicated 1V/Oct input. This
means you’re free to use FM1
for more creative modulation
duties, while using the
dedicated 1V/OCT input for
tracking pitch.
[3] FM2 - Controls the amount and
polarity of the FM2 input. The
FM input has maximum
positive effect when the knob
is fully clockwise; maximum
inverted effect when fully
counter-clockwise; and no
effect when at the 12 o’clock position.
[4] MODE - This knob cycles between the different Morgasmatron filter modes. The modes are
LP2 (2-pole lowpass), LP1 (1-pole lowpass), BP1 (1-pole bandpass), HP1 (1-pole highpass),
HP2 (2-pole highpass), and BR1 (1-pole band reject, or ‘notch’).
[5] Q - Sets the resonance of the filter. The knob position is combined with the Q input.
[6] Q-DRIVE - Adds additional drive to the filter resonance. This keeps resonance levels high as
the gain levels increase, while providing a warming “growl” at mid Q values.
