Chapter 5 ES E 120
ES E LFO parameters
The LFO (low frequency oscillator) generates a cyclic waveform that is used to modulate the ES E
waveform. The behavior and eect 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 eect—depending on the LFO speed and intensity.
•
If Wave is set to a pulse wave, the LFO modulates the waveform’s pulse width—pulse width
modulation (PWM).
LFO parameters
•
Vib(rato)/PWM knob: Rotate to dene the intensity of LFO modulation.
•
Speed knob: Rotate to set the frequency of LFO modulation.
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 parameter’s 12 o’clock position (50% rectangular) for the pulse width, if you
want to achieve the maximum modulation range.
