AutoWah Attack/Release
These parameters allow you to define how much time it takes for the Wah filter to open
and close. Range (in milliseconds): 10 to 10,000
Comp Ratio
The Comp Ratio of the integrated compressor can be adjusted between 1:1 (no
compression) and 30:1. The Compressor is tied to the Fuzz effect, and always precedes
it. As such, the FX Order parameter is very important for placement of the Compressor
in the effects chain.
Fuzz Gain
Controls the level of Fuzz (distortion). Range: 0 dB to 20 dB.
Fuzz Tone
The integrated Fuzz effect can be adjusted, tonally, with this parameter. Range: 2000 Hz
to 20,000 Hz
EVOC 20 Filterbank
The EVOC 20 FB consists of two formant filter banks, which are also used in Logic’s
EVOC 20 PS vocoder. More information on the filter banks are found in “How Does a
Filter Bank Work?” on page 168.
The input signal runs through both filter banks in parallel. Each bank features
independent volume faders for each band, allowing levels to be set freely—ranging
from unchanged through to silence. The latter completely suppresses the selected
formants in the overall sound spectrum. Use of the Formant Stretch and Formant Shift
parameters provide total control over the position and width of the filter bands. In
addition, you can also crossfade between the two filter banks.
