• Amount knob: Specify the amount of pitch shift as a percentage. At 100%, all
partials are set to the pitch determined by the Pitch knob. At 50%, all partials
are moved halfway to the target pitch. Subtle use of this parameter can turn
harmonic pitched sounds into atonal bell-like timbres, for example.
• Pitch knob: Set the target pitch. All partials are shifted toward the target when
the Amount knob is rotated. At low positions, partial pitches shift down. Toward
100%, partial pitches shift up. At 50%, high partial pitches shift down and low
partial pitches shift up. Adjust the knob to balance the shift and to control the
brightness of any atonal, inharmonic elements that may be introduced to the
sound.
• Noise: Applies noise to shift the tunings of partials. This can lead to chaotic effects.
• Amount knob: Set the amount of noise applied to partials.
• Rate knob: Set the rate at which the noise value is changed, with a smooth ramp
of pitches between these points.
• Smooth knob: Set a response that varies between an instant change at each new
value through to a gradual ramp over the entire time period.
• Min. Partial knob: Set the amount that noise affects low or high partials by
specifying the minimum partial that is altered by the effect.
Additive effect 3 parameters
• Additive effect on/off button: Enable or disable the additive effect unit.
• Additive effect 3 pop-up menu and field: Choose an effect type that is used to process
the output of the additive element.
• Auto Pan: Modulates the pan positions of all partials from left to right in a regular
pattern.
• Amount knob: Set the depth of the stereo panning effect.
• Rate knob: Set the speed of the stereo panning effect.
• Ramp knob: Set the panning amount for lower partials. This can create a subtle
widening of the sound, with less obvious left to right movement in the lowest
partials.
• Cycles knob: Set phase differences between partials. At zero, all partials are in-
phase. Higher values lead to a finer, more subtle and complex effect.
• Comb: Applies a comb filter to the output of the additive element.
• Amount knob: Set the depth of the comb filter effect.
• Damp knob: Set the duration of each dip (or notch) in the comb.
• Freq knob: Set the frequency of the filter. The range is from 16 Hz to 20 kHz.
• F-Back knob: Set the amount of feedback.
• EQ: Applies an EQ to the output of the additive element. Crossover frequencies are
centered at 120 Hz, 800 Hz, and 5000 Hz, with a one octave transition between
bands.
• Low knob: Set the amount of low frequency cut or boost.
• Low Mid knob: Set the amount of lower mid frequency cut or boost.
