Chapter 14 EVOC 20 PolySynth 155
Oscillator Section
The EVOC 20 PolySynth is equipped with a two oscillator digital synthesizer which
features a number of waveforms, and FM (Frequency Modulation). Further to these
sound-generators in the Synthesis section is an independent noise generator.
There are two oscillator modes.
 Dual: Two oscillators make use of single-cycle digital waveforms to provide the
synthesis sound source(s).
 FM: A two operator FM engine, with Oscillator 1 as a sine wave carrier, and Oscillator
2 as the modulator. Oscillator 2 can use any of the single-cycle digital waveforms.
You can switch between Dual and FM modes by clicking on the Dual or FM label(s) to
the top left of the section shown in the screenshots above.
As you can see, there are some subtle differences between the two modes. This section
will cover the common parameters first, and will then explain the mode-specific
options.
Wave 1 Parameters
The footages below the Wave 1 label in both modes harks back to the days of pipe
organs. The longer the pipe, the deeper the tone. This also applies to Wave 1. Simply
click on the 16, 8, or 4 foot value to select the range in which Wave (oscillator) 1
functions. Your selection will be illuminated.
The numerical value beside the Wave 1 label indicates the currently selected waveform
type. The EVOC 20 PolySynth features 50 waveforms with different sonic characteristics.
