Chapter 14 The EVOC 20 PS 187
When high settings are used, the increased sensitivity to unvoiced signals can lead to
the U/V source—determined by the Mode parameter—being used on the majority of
the input signal, including voiced signals. Sonically, this results in a sound that
resembles a radio signal which is breaking up, and contains a lot of static or noise.
Mode
Mode selects the sound source(s) that can be used to replace the unvoiced content of
the input signal. Possible settings are Off, Noise, Noise + Synth, or Blend.
• Noise—uses noise alone for the unvoiced portions of the sound.
• Noise + Synth—uses noise and the synthesizer for the unvoiced portions of the
sound,
• Blend—uses the Analysis signal after it has passed through a highpass filter, for the
unvoiced portions of the sound. This filtered Analysis signal is then mixed with the
EVOC 20 PS output signal. The Sensitivity parameter has no effect when this setting is
used.
Level
The Level knob controls the volume of the signal (Noise, Noise + Synth, or Blend) used to
replace the unvoiced content of the input signal.
Warning: Care should be taken with this control, particularly when a high Sensitivity
value is used, to avoid internally overloading the EVOC 20 PS.
