P2 Resonance / Depth
Resonance is adjusted using the primary
function of
P2 (indicator off). The diagrams
show the different resonances for each
Filter type.
LP and HP Filter Resonance determines
how peaked the cutoff is, which is
adjustable over a range of 0.7 to 3.0.
BP Filter Resonance determines the
width of the peak, which is adjustable
over a range of 0.7 to 3.0.
Depth is adjusted using the second
function of
P2 (green indicator on).
Depth sets how far the sweep of the
LFO (low frequency oscillator) modulates
the Frequency set by
P1. The Depth is
adjustable ±4.5 octaves. The full range is
reached in 1
1 /
3
rotations of P2. With Depth
at minimum, the LFO ceases to have any
effect, and
P1 becomes a manual sweep
control.
J2 Wet / Dry Mix
Pressing J2 toggles between transform
operation (indicator off) and Wet / Dry
control (green indicator on). The filter
default is 100% wet. Holding the joystick
left goes more Dry, to the right goes more
Wet. Moving the joystick up provides
instant, momentary 100% Wet. Moving
the joystick down provides instant,
momentary 100% Dry. This allows Wet or
Dry transforming with the control returning
to the set Wet/Dry ratio when the control
is at rest (in the center).
Phaser / Flanger
Control Assignments
Phasing is a swept comb-filter effect with
no linear harmonic relationship between
the comb teeth. Splitting an audio signal
in two, shifting the phase of one signal by
passing it through an all-pass filter, then
recombining, creates the phasing effect.
The control response is shown below.

A Flanger creates a unique “flyover”
sound by creating a set of equally spaced
notches in the the frequency spectrum in
a linear harmonic comb filter. This is done
by mixing a signal with a slightly delayed
copy of itself and by constantly changing
the length of the delay.
Both effects use an LFO to cause the
comb peaks and notches to sweep up
and down the frequency spectrum.
