EFFECT TYPES
The following are brief technical descriptions of the filter effects included
in the
BEF Pro. Some of the filter types are intended to approximate, but
not exactly copy, some common and well-known bass envelope filter ef-
fects. These are marked below.
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). This setting creates sounds similar to the 3leaf Groove Regulator
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. This setting creates sounds similar to the
Pigtronix EP-1.
04 Notch, Notch, Resonant low pass. Same as 03, but with two notches.
