EFFECT TYPES
The following are brief technical descriptions of the filter effects included
in the Poly-Mod
Pro . Some of the filter types are intended to approximate,
but not exactly copy, some common and well-known envelope filter
effects.
2 POLE FILTERS
00 Three two-pole resonant low-pass filters in parallel.
01 Resonant low pass. A flat response at low frequencies, rising to a
resonant peak, and then falling at 12 dB/octave. Low resonance
(low Q).
02 Resonant low pass. High resonance (high Q).
03 Notch, Resonant low pass. The frequency response begins flat, then
has a deep notch, then back to flat, and then a resonant peak fol-
lowed by a
12 dB/octave fall.
04 Notch, Notch, Resonant low pass. Same as 03 , but with two notches.
