PAN SECTION
The PAN section, when in stereo operation, modulates your signal between the left and
right output. In mono operation, in effect the PAN section acts as another TREM
section, but with the wave shapes all inverted.
DEPTH: The depth control affects the spread of the modulation. At maximum, your
signal will modulate from 100% in the left channel to 100% in the right channel. As you
bring DEPTH down, the modulation spread is lessened, or in effect "pulled back" into
the center of the stereo field.
FILTER SECTION
The FILTER section offers three modulated filters modes:
Low Pass Filter (LPF): Frequencies above a modulated cutoff point are cut
High Pass Filter (HPF): Frequencies below a modulated cutoff point are cut
Band Pass Filter (BPF): Frequencies above and below a modulated center point are cut
MODE: The MODE button toggles through the three filter modes.
DEPTH: The DEPTH knob sets the high point of the cutoff modulation
RES: The RESONANCE knob increases the emphasis on frequencies right at the cutoff
point of the filter, emphasizing the sweeping effect. In BPF mode, increasing the
resonance also shrinks the bandwidth of the filter, meaning more frequencies above
and below the center point are cut.
R INV: The R INV button is used in stereo operation. With the button pressed in, it
inverts the LFO in the right channel. This is great when using a mono in/stereo out
setup to give a mono input a stereoized effect.

VOLUME

The VOL knob in the top left corner controls the master output volume of the effect.
This master volume setting is saved and recalled via presets.

SIGNAL PATH

When all four sections are active, the signal path is FILTER -> MOD -> TREM -> PAN.
