ES E
Speed
Speed controls the frequency of the pitch (sawtooth) or pulse width modulation.
Cutoff
This parameter sets the cutoff frequency of the resonance-capable dynamic lowpass
filter.
Resonance
This parameter sets the resonance of the ES E’s dynamic lowpass filter.
AR Int
The ES E features one simple envelope generator per voice. It features an Attack and a
Release parameter. AR Int, defines the amount of cutoff frequency modulation applied
by the envelope generator.
Velo Filter
This parameter sets the velocity sensitivity of the cutoff frequency modulation applied
by the envelope generator. This parameter is only effective if AR Int is not set to 0.
Attack
This parameter sets the attack time of the envelope generator.
Release
This parameter sets the release time of the envelope generator.
Velo Volume
This parameter determines the amount of velocity sensitivity, with each note being
louder if struck more firmly.
Volume
This parameter sets the master volume of the ES E.
Chorus/Ensemble
The ES E features a chorus/ensemble effect, with three switchable variations (plus off ).
