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.
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%.
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.
