This chapter covers Logic’s filter effects.
The filter effects include the AutoFilter, Fuzz-Wah, EVOC 20 FB, EVOC 20 TO, Low/High
Pass Filter and Low/High Cut plug-ins. The EVOC 20 TO is based on a vocoder. Further
information about vocoders can be found in the chapter “Vocoder—Basics” on
page 167.
AutoFilter
The AutoFilter is an extremely versatile, resonance-capable lowpass filter, that offers a
couple of truly unique features. The most important parameters are located to the right
side of the Plug-in window: The Cutoff Freq. knob determines the point where the filter
kicks in. Higher frequencies are attenuated, lower frequencies are allowed to pass
through.
