POLY –

MODE: The mode button cycles through two sets of controls for the

mini knobs CTRL 1 and CTRL 2. In mode 1, POLY reverb is in Interval

Edit mode. In mode 2, POLY Reverb is in Mix Edit mode. See the mini

knob details below for descriptions of their functions.

CTRL 1: In Interval Edit mode (Mode 1), this knob controls the

semitone shift interval of the first pitch shifter. At noon, there’s no

shift. As you turn counter-clockwise, the shift decreases to -1 octave

at its minimum. As you turn clockwise, the shift increases to +1 octave

at its maximum.

In Mix Edit mode (Mode 2), this knob controls the volume balance of

the unshifted and shifted signals before they enter the reverb. A fully

counter-clockwise knob corresponds to a fully unshifted mix, while a

fully clockwise knob corresponds to a mix of only the shifted signals.

CTRL 2: In Interval Edit mode (Mode 1), this knob controls the

semitone shift interval of the second pitch shifter, over the same

range.

In Mix Edit mode (Mode 2), this knob controls the volume balance of

the two shifted signals. At noon, there’s an equal-power mix of the

two pitch shifters. The counter-clockwise extreme of the knob mixes

100% of the first pitch shifter and 0% of the second pitch shifter

output, while the clockwise extreme mixes the opposite: 0% of the

first pitch shifter and 100% of the second pitch shifter.

RESONANT –

MODE: Selects between two resonant algorithms. Mode 1 inserts

pentatonically-tuned resonators in the reverb signal chain, allowing

notes to ring when their fundamentals and harmonics excite the

pitches of the resonators. Mode 2 applies resonant filtering with

configurable gain and center-frequency to the reverb algorithm,

gradually collapsing the reverb tail into a focused, narrow frequency

band.

AMOUNT: Controls the degree of the effect. In Mode 1, this knob

sets the volume of the tuned resonators. As AMOUNT is turned

clockwise, the ringing pitches get louder. In Mode 2, the AMOUNT

knob sets the feedback of the resonant filter. As AMOUNT is turned

clockwise, the filtered reverb tail builds more quickly, eventually

achieving unstable self-oscillation.

TUNING: Controls the tuning of the resonance effects. In Mode 1,

this knob selects the key of the resonators. When fully counter-

clockwise, the TUNING knob selects an A5 (880Hz) minor pentatonic

scale. Turning the knob clockwise increases the key in increments of
