Filters
To generalize, there are basically four types of filter: an LPF
(Low Pass Filter), an HPF (High Pass Filter), a BPF (Band
Pass Filter) and a BEF (Band Elimination Filter). Each
available filter has a different frequency response. There
are also combinations of LPF and HPF.
LPF (Low Pass Filter):
This only passes signals below the Cutoff frequency. You
can then use the Reso (Resonance) parameter to add further
character to the sound. Six types of LPF are available.

LPF24D (Low Pass Filter 24dB/oct Digital)
A 4-pole (-24db/oct) dynamic LPF with a strong Resonance.
LPF24A (Low Pass Filter 24dB/oct Analog)
A 4-pole (-24db/oct) dynamic LPF with a character similar
to those found on analog synthesizers.
LPF18 (Low Pass Filter 18dB/oct)
A 3-pole (-18db/oct) dynamic LPF.
LPF18S (Low Pass Filter 18dB/oct Staggered)
Also a 3-pole (-18db/oct) dynamic LPF, but with a
shallower frequency curve.
LPF12 (Low Pass Filter 12dB/oct)
A 2-pole (-12db/oct) dynamic LPF, designed to be used in
combination with an HPF (High Pass Filter).
LPF6 (Low Pass Filter 6dB/oct)
A 1-pole (-6db/oct) dynamic LPF with no Resonance,
designed to be used in combination with an HPF (High
Pass Filter).
