ES E LFO parameters in MainStage
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 pulse width—pulse width modulation (PWM).
LFO parameters
Vib/PWM knob: Define the intensity of LFO modulation.
Speed knob: 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. Set the Wave parameter to the 12 o’clock position (50% rectangular) for pulse width to attain the maximum modulation range.
