ESP
Logic Pro ESP overview
The eight-voice ESP (ES Poly) emulates classic polyphonic synthesizers of the 1980s.
It is a versatile instrument that is capable of producing a huge variety of useful musical
sounds. The creation of classic analog synthesizer brass sounds is just one of its many
strengths.
ESP produces sounds using subtractive synthesis. It features an oscillator that generates
harmonically rich waveforms. You subtract—cut, or filter out—portions of these waveforms
and reshape them to create new sounds.
If you’re new to synthesizers, see Synthesizer basics overview, which will introduce you
to the terminology and give you an overview of different synthesis methods and how they
work.
ES P is divided into several areas.
Oscillator parameters: The oscillator sliders are shown in the area to the left. The octave
parameters are also found in this section. The oscillators generate the basic waveforms
that form the basis of your sound. See Logic Pro ESP oscillator parameters.
LFO parameters: The LFO parameters (to the right of the oscillator parameters) are
used to modulate the sound. See Logic Pro ESP LFO parameters.
Filter parameters: The vertical column in the center includes the (cutoff) Frequency
and Resonance knobs and the key follow buttons. The filter is used to contour the
waveforms sent from the oscillators. See Logic Pro ESP filter parameters.
