Blend: Uses the analysis signal after it has passed through a highpass filter for the
unvoiced portions of the sound. The Sensitivity parameter has no effect when this
setting is used.
Level knob: Controls the volume of the signal used to replace the unvoiced content of
the input signal.
Important: Take care with the Level knob, particularly when a high Sensitivity value is
used, to avoid internally overloading the EVOC 20 PolySynth.
EVOC 20 PolySynth Synthesis Section Parameters
The EVOC 20 PolySynth is equipped with a polyphonic synthesizer. It is capable of
accepting MIDI note input. The parameters of the Synthesis section are described below.
Global parameters
Tuning and Pitch
parameters
Oscillator parameters
Envelope parameters
Filter parameters
Oscillator parameters: Used to choose the basic waveforms for the synthesis engine of
the EVOC 20 PolySynth. See EVOC 20 PolySynth Oscillator Parameters.
Tuning and Pitch parameters: Control the overall tuning of the synthesizer, and aspects
such as pitch bend and portamento. See EVOC 20 PolySynth Tuning and Pitch
Parameters.
Filter parameters: Used to shape the basic waveforms of the oscillators. See EVOC 20
PolySynth Filter Parameters.
Envelope parameters: Provide level control of the attack and release phases of the
synthesizer sound. See EVOC 20 PolySynth Envelope Parameters.
