Track—allows you to use the audio track, into which the EVOC 20 TO is inserted, as
the Synthesis source signal.
Side Chain—allows you to use another audio track as the source material for the
Synthesis section. Selection of the Side Chain track is achieved by click-holding on the
Side Chain pull-down menu in the gray area at the top of the Plug-in window.
Note: If no Side Chain track is assigned in the Side Chain pull-down menu, the tracks
signal will be used.
Bands
The Bands window determines the number of frequency bands used by the
EVOC 20 TO. It ranges from 5 to 20. Adjustments are made by using the mouse as a
slider. The greater the number of bands, the more precisely the sound can be reshaped.
Note: Increasing the number of bands also increases the processor overhead.
The Tone Generator of the Tracking Oscillator
Depending on the position of the FM Int control, the tracking oscillators delivers either;
a sawtooth wave or the signal of an FM tone generator.
The FM tone generator consists of two oscillators, each generating a sine wave. The
frequency of Oscillator 1 is linearly modulated by Oscillator 2. This deforms the sine
wave of Oscillator 1 to a waveform with rich harmonic structure. Its harmonic structure
depends on the modulation intensity and the frequency ratio of both oscillators.
Tune
Coarse Tune offsets the pitch of the oscillator in semitones by up to ±2 octaves.
Fine Tune: The default value is concert pitch A = 440 Hz. The range is from 425.00 to
455.00 Hz.
