Using the ES1 Oscillators
The ES1 features a primary oscillator and a sub-oscillator. The primary oscillator generates
a waveform, which is then sent to other parts of the synthesizer for processing or
manipulation. The sub-oscillator generates a secondary waveform one or two octaves
below that of the primary oscillator.
Wave knob: Selects the waveform of the primary oscillator, which is responsible for the
basic color of the tone. See Setting ES1 Oscillator Waveforms.
Mix slider: Defines the level relationship between the primary and sub-oscillator signals.
When the sub-oscillator is switched off, its output is completely removed from the
signal path.
Sub knob: The sub-oscillator generates square, pulse, and white-noise waveforms. It
also allows you to route a side chain signal through the ES1 synthesizer engine (see
Using the ES1 Sub-Oscillator).
2, 4, 8, 16, 32 buttons: Transpose the pitch of the oscillators up or down by octaves. The
lowest setting is 32 feet, and the highest is 2 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 (for a description of the global Tune parameters, see
Adjusting Global ES1 Parameters).
