Oscillators 2 and 3 can be synchronized to, or ring modulated with, Oscillator 1. They
also have rectangular waves with either user-defined fixed-pulse widths or pulse width
modulation (PWM) features.
You can use the modulation router to simultaneously change the pulse widths of the
rectangular waves of Oscillator 1 and the synchronized and ring-modulated rectangular
waves of Oscillators 2 and 3.
Getting to Know the ES2 Oscillators
The following section gives you an overview of the parameters available for each oscillator.
You can find the oscillators in the area at the top left of the ES2 interface.

Oscillator on/off buttons: Click the oscillator number to the right of each oscillator to
activate or deactivate each oscillator independently. A green numeric button indicates
an active oscillator. A gray numeric button denotes an inactive oscillator. Deactivating
an oscillator saves computer processing power as you are not merely muting it—you
are actually turning it off.
Wave knobs: Sets the type of waveform that an oscillator generates. The waveform is
responsible for the basic tonal color. See Using the ES2’s Basic Oscillator Waveforms.
(Coarse) Frequency knobs: Sets the oscillators pitch—in semitone steps, over a range
of ±3 octaves. As an octave consists of 12 semitones, the ±12, 24, and 36 settings
represent octaves.
