High Mid knob: Set the amount of upper mid frequency cut or boost.
High knob: Set the amount of high frequency cut or boost.
Filter: Applies a continuously variable lowpass/highpass filter to the output of the
additive element.
Amount knob: Set the depth of the filter effect.
LP - HP knob: Set the shape of the filter blending between a low pass, band pass,
and high pass filter.
Cutoff knob: Set the cutoff frequency. The range is from 16 Hz to 20 kHz.
Res knob: Adjust the level of frequencies surrounding the cutoff frequency.
Spread: Modulates the pan positions of all partials to create a wide pseudo-stereo
effect. Partials are panned left to right in a regular pattern, with every second partial
position inverted.
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.
Strum: A filter that modulates the amplitudes of partials to create interesting effects,
some of which can be reminiscent of guitar strumming.
Amount knob: Set the depth of the effect.
Partial knob: Select the partial (number) that you want to set to full amplitude.
Modulating the partial number can create rhythmic melodic effects.
Release knob: Set the release (or decay) time for the selected partial. Shorter
release times and slower modulation of the partial number can create strumming
of partials.
Width knob: Set the number of partials in a range surrounding the selected
partial.
Ripples: Applies a sine wave to the amplitude of partials, resembling waves or ripples
in water.
Amount knob: Set the depth of the effect.
Group knob: Select a group of partials to be processed.
Period knob: Set the number of partials over which one full cycle of the sine wave
is applied. For example, a value of 10 applies a sine wave shape over partials
1-10, 11-20, 21-30, and so on.
Phase knob: Set the phase of the sine wave. Modulate this with a ramp up LFO for
smooth sound changes.
