Note: When the pulse width becomes very narrow, the signal sounds as if it is being
interrupted (“breaking up”). Given this potential artifact, set the PWM intensity with
care, and select the Wave parameters 12 o’clock position (50% rectangular) for the
pulse width, if you want to achieve the maximum modulation range.
Using the ES E Filter
The ES E includes a lowpass filter that lets you contour the output from the oscillator.
Cutoff knob: Controls the cutoff frequency of the ES E filter.
Resonance knob: Boosts or cuts 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: The ES E features one simple envelope generator per voice-offering an
Attack and a Release parameter (see Using the ES E Envelope). The AR Int knob defines
the amount (depth) of cutoff frequency modulation applied by the envelope generator.
Velo Filter knob: Sets 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.
