Noise generator slider: Set the level of white noise. This is the raw material for classic
synthesizer sound effects, such as waves, wind, and helicopters.
4, 8, and 16 buttons: Set 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.
Logic Pro ESP LFO parameters
ESP features an LFO (low frequency oscillator) which can do either of the following:
Modulate the frequency of the oscillators, resulting in a vibrato
Modulate the cutoff frequency of the dynamic lowpass filter, resulting in a wahwah
effect
LFO parameters
Vib/Wah knob: Turn to the left to set a vibrato; turn to the right to cyclically modulate
the filter.
Speed knob: Set the rate of the vibrato or cutoff frequency modulation.
Logic Pro ESP filter parameters
ESP includes a lowpass filter that lets you contour the output signals from the oscillator.
