Z-Plane Filters
Z-Plane Filters
A filter is a device which changes the output of a signal (sound) by
removing certain elements of the signal based on the frequency and
amplitude. The “Order” of a filter defines the number of filter elements it
contains. The more elements, the more complex the filter.
XL-7 contains 50 different types of E-MU’s celebrated Z-plane filters. In
addition to the standard Low pass, High pass and Band pass filters, XL-7
contains Swept Octave Equalizers, Phasers, Flangers, Vocal Formant Filters,
and digital models of classic synthesizer filters.
In the filter chart below you will notice that the “Order” of the filters varies
from 2 to 12 order. Higher order filters have more sections and can produce
more complex formants. XL-7 can produce 128 filters of up to 6th order or
64 filters of 12th order complexity. Therefore, if you decided to use all 12th
order filters, XL-7 would be limited to 64 voices.
