16 ES E
This chapter discusses the eight-voice polyphonic ES E
synthesizer.
The ES E (ES Ensemble) is designed for pad and ensemble sounds. It is great for adding
atmospheric beds to your music, with minimal CPU overhead. All ES E parameters are
discussed in the following section.
 4, 8, 16 buttons: Determine the ES E’s octave transposition.
 Wave knob: The left-most setting of the Wave parameter causes the oscillators to
output sawtooth signals—which can be frequency modulated by the integrated LFO.
Across the remaining range, the oscillators output pulse waves, with the average
pulse width being defined by the Wave parameter.
 Vib/PWM knob: If Wave is set to sawtooth, this parameter defines the amount of
frequency modulation, resulting in a vibrato or siren effect—depending on the LFO
speed and intensity. If Wave has been set to a pulse wave, this parameter controls the
amount of pulse width modulation (PWM). When the pulse width becomes very
narrow, the sound sounds like it is being interrupted (“breaking up”). Given this
potential artifact, set the PWM intensity with care, and select the Wave parameter’s
12 o’clock-position (50% rectangular) for the pulse width, if you want to achieve the
maximum modulation range.
 Speed knob: Controls the frequency of the pitch (sawtooth), or pulse width
modulation.
 Cutoff knob: Sets the cutoff frequency of the resonance-capable, dynamic lowpass
filter.
