Using the ES E Oscillators
The synthesizer oscillator generates a waveform, which is then sent to other portions of
the synthesizer engine for processing or manipulation.
Wave knob: Selects the waveform of the oscillator, which is responsible for the basic
color of the tone. The leftmost setting of the Wave parameter causes the oscillators to
output sawtooth signals. Across the remaining range, the oscillators output pulse waves,
with the average pulse width being defined by the Wave parameter position.
4, 8, 16 buttons: Allow you to switch the pitch in octaves (transpose it up or down). The
lowest setting is 16 feet, and the highest is 4 feet. The use of the term feet to determine
octaves comes from the measurements of organ pipe lengths. The longer (and wider)
the pipe, the deeper the tone.
Using the ES E LFO
The LFO (low frequency oscillator) generates a cyclic waveform that is used to modulate
the ES E waveform. The behavior and effect of the LFO depend on whether a sawtooth
or pulse wave is selected.
If Wave is set to sawtooth, the LFO modulates the frequency of the waveform, resulting
in a vibrato or siren effect—depending on the LFO speed and intensity.
If Wave is set to a pulse wave, the LFO modulates the waveform’s pulse width (PWM).
Vib/PWM knob: Defines the intensity of the LFO modulation.
Speed knob: Sets the frequency of the LFO modulation.
