Envelope and level parameters: The area to the right of the filter parameters contains
the envelope and level parameters, which control the level of the sound over time. See
Logic Pro ESP envelope and level controls.
Effect parameters: The area at the extreme right contains the Chorus and Overdrive
parameters. These can be used to color or thicken the sound. See Use the Logic Pro
ESP effects processor.
Extended parameters: Not shown in the image, the extended parameters are accessed
by clicking the disclosure triangle at the lower left of the interface. These parameters
include bend and tuning functions. See Logic Pro ESP extended parameters.
Logic Pro ESP oscillator parameters
ESP features several oscillators that output different waveforms. These signals can be
mixed together—at different levels—providing countless variations of the raw material used
for your sounds.
In addition to triangular, sawtooth, and rectangular waves, the rectangular waves of two
sub-oscillators are also available. The left sub-oscillator fader is one octave lower than the
main oscillators, and the right sub-oscillator fader is two octaves lower. Use these to fatten
up the sound.
Oscillator parameters
Triangle oscillator slider: Set the level of the triangle waveform output by the oscillators.
Sawtooth oscillator slider: Set the level of the sawtooth waveform output by the
oscillators.
Rectangle oscillator slider: Set the level of the rectangle waveform output by the
oscillators. The pulse width is fixed at 50%.
Sub-oscillator -1 octave slider: Set the level of the (rectangular) sub-oscillator
waveform, which is one octave lower than the main oscillators. Use this to thicken the
sound. The pulse width is fixed at 50%.
Sub-oscillator - 2 octaves slider: Set the level of the (rectangular) sub-oscillator
waveform, which is two octaves lower than the main oscillators. Use this to thicken the
sound. The pulse width is fixed at 50%.
