Filter 2
This is an all-pass filter that creates peaks and notches in the sound, relative to a certain frequency
(the cutoff) and to varying extremes (the resonance).
The red button switches the filter on/off.
The Cutoff and Resonance dials control the frequency and intensity
of the filter.
The Modulation dial controls the depth of the LFO, with a switch
to set its target.
The Speed dial controls the frequency of the LFO.
Filter 2 can be modulated by a dedicated LFO. This is sine-shaped and creates a smooth sweeping
effect when the Modulation dial is raised. The LFO modulator has two possible targets, selectable by
the switch next to its dial—the filter cutoff (C) or resonance (R).
Global LFO
This LFO is a modulator with multiple possible shapes and targets, and is different from the LFO
within Filter 2.
The red button switches the LFO on/off.
The overall depth of the LFO is set by the Amount dial. Its
frequency is controlled by the Speed dial.
The LFO’s shape can be switched between sine, rectangle and
sawtooth.
The effect of the LFO on each possible target is controllable
individually with the Amplitude, Pitch and Filter 1 dials and switch.
After setting its depth using the Amount dial, you can make the LFO modulate amplitude, pitch, and
Filter 1 to different extents by raising their respective dials.
The LFO can modulate either the cutoff (C) or emphasis (E) of Filter 1, selectable by the switch next
to the Filter 1 dial.
 If the Amount dial is at zero, the LFO will have no effect, regardless of the positions of the
target dials.
