EVOC 20 PolySynth filter parameters
The Synthesis section includes a lowpass filter that is used for coarse signal shaping, before the
signal is more precisely shaped by the individual bands of the formant filter banks.
Filter parameters
••
Cutoff knob: Rotate to set the cutoff frequency of the lowpass filter. Turn to the left to remove
high-frequency content from the synthesizer signal.
••
Resonance knob: Rotate to boost or cut the signal portion that surrounds the frequency
defined by the Cutoff knob.
Tip: Set cutoff as high as possible, then adjust resonance to achieve a brighter high-end signal.
This is useful for achieving better speech intelligibility.
EVOC 20 PolySynth envelope parameters
EVOC 20 PolySynth includes an Attack/Release envelope generator that controls the levels of the
oscillators over time.
Envelope parameters
••
Attack slider: Drag to set the time it takes for the oscillators to reach their maximum level.
••
Release slider: Drag to set the time it takes for the oscillators to reach their minimum level, after
the keys have been released.
