ES E LFO parameters<br />
The LFO (low frequency oscillator) generates a cyclic waveform that is used to modulate the ES E<br />
waveform. The behavior and effect of the LFO depend on whether a sawtooth or pulse wave<br />
is selected.<br />
••<br />
If Wave is set to sawtooth, the LFO modulates the frequency of the waveform, resulting in a<br />
vibrato or siren effect—depending on the LFO speed and intensity.<br />
••<br />
If Wave is set to a pulse wave, the LFO modulates the waveform’s pulse width—pulse width<br />
modulation (PWM).<br />
LFO parameters<br />
••<br />
Vib(rato)/PWM knob: Rotate to define the intensity of LFO modulation.<br />
••<br />
Speed knob: Rotate to set the frequency of LFO modulation.<br />
Note: When the pulse width becomes very narrow, the signal sounds as if it is being<br />
interrupted—“breaking up.” Given this potential artifact, set the PWM intensity with care, and<br />
select the Wave parameter’s 12 o’clock position (50% rectangular) for the pulse width, if you<br />
want to achieve the maximum modulation range.<br />
