ES E includes a lowpass filter that lets you contour the output from the oscillator.
Cutoff knob: Control the cutoff frequency of the filter.
Resonance knob: Boost or cut portions of the signal that surround the frequency defined by the Cutoff parameter.
Note: Increasing the Resonance value results in a rejection of bass—low frequency energy—when using lowpass filters.
AR Int knob: Set the amount (depth) of cutoff frequency modulation applied by the envelope generator.
Note: ES E provides one envelope generator per voice, offering Attack and Release (AR) parameters (see ES E envelope parameters).
Velo Filter knob: Set the velocity sensitivity of the cutoff frequency modulation applied by the envelope generator.
Note: This parameter has no effect if AR Int is set to 0.
