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.
U/V Level knob: Set the volume of the signal used to replace the unvoiced content in 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 parameters
Logic Pro EVOC20 PolySynth synthesis overview
EVOC20 PolySynth is equipped with a polyphonic synthesizer that accepts MIDI note
input. Synthesis section parameters are outlined below.
Synthesis parameters
Oscillator parameters: Determine the basic waveforms for the synthesis engine of the
EVOC20 PolySynth. See Logic Pro EVOC20 PolySynth oscillators.
Tuning and Pitch parameters: Control the overall tuning of the synthesizer, and aspects
such as pitch bend and portamento. See Logic Pro EVOC20 PolySynth tuning and pitch
controls.
Filter parameters: Shape the basic waveforms of the oscillators. See Logic Pro EVOC20
PolySynth filters.
Envelope parameters: Control the level of the attack and release phases of the
synthesizer sound. See Logic Pro EVOC20 PolySynth envelopes.
Global parameters: Determine the keyboard mode and number of voices used by the
EVOC20 PolySynth. (The Global parameters are located at the top left of the interface.)
