EVOC 20 PolySynth oscillator parameters
EVOC 20 PolySynth oscillators overview
EVOC 20 PolySynth has two oscillators, which you can switch between Dual mode and FM mode.
The Synthesis section also incorporates a noise generator that can add a further color to
your sound.
Click here to switch
between Dual and FM
mode.
••
Dual mode: Each oscillator allows you to choose a digital waveform.
••
FM mode: Oscillator 1 generates a sine wave. The frequency, or pitch, of oscillator 1 is
modulated by oscillator 2. This leads to a number of different tones and harmonics becoming
audible. Oscillator 2 can use any available digital waveform. See Frequency modulation (FM)
synthesis on page 493).
Each mode subtly changes the parameters shown in the oscillator section.
Both Dual and FM mode provide the following common parameters.
Common oscillator parameters
••
16', 8', 4' value buttons: Click to set the octave range for oscillator 1. 16' (16 feet) is the lowest,
and 4' the highest setting. 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.
••
Wave 1 and Wave 2 fields: Choose the waveform type for oscillators 1 and 2. There are 50 singlecycle
digital waveforms with different sonic characteristics.
