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).
- Speed knob: Sets the frequency of the 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.
