90 Chapter 15 ES P
Vib/Wah
The ES P features an LFO which can either modulate the frequency of the oscillators
(resulting in a vibrato), or the cutoff frequency of the dynamic low pass filter (resulting
in a wah wah effect). Turn the control to the left in order to set a vibrato, or to the right
to cyclically modulate the filter.
Speed
Speed controls the rate of the oscillator frequency or cutoff frequency modulation.
Frequency
This parameter set the cutoff frequency of the resonance-capable dynamic low pass
filter.
Resonance
This parameter sets the resonance of the dynamic lowpass filter. Increasing the
Resonance value results in a rejection of bass (low frequency energy) when using low
pass filters. The ES M compensates for this side-effect internally, resulting in a more
bassy sound.
1/3, 2/3, 3/3
The cutoff frequency can be modulated by MIDI note number (keyboard position); you
may know this parameter as Keyboard Follow on other synthesizers. You have the
choice of: no modulation, one third, two thirds, or full keyboard follow (3/3). When set
to 3/3, the relative harmonic content of each note is the same, independent of its pitch.
ADSR Int
The ES P features one ADSR envelope generator per voice. ADSR Int sets the amount of
cutoff frequency modulation by the ADSR envelope generator.
Velo Filter
The cutoff frequency modulation by the ADSR envelope generator is velocity sensitive.
The amount of velocity sensitivity is set by this parameter.
Volume
This parameter sets the master volume of the ES P.
Velo Volume
This parameter determines the amount of velocity sensitivity, with each note being
louder if struck more firmly.
A
The A slider determines the attack time of the envelope generator.
D
The D slider determines the decay time of the envelope generator.
