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