Filter Type List
[VOICE] [EDIT] Element selection
LPF24D (24dB/oct Digital Low Pass Filter)
A dynamic 24dB/oct low-pass filter with a
characteristic digital sound. Compared to the
LPF24A type (below), this filter can produce a
more pronounced resonance effect.

These frequencies are
"passed" by the filter.
LPF24A (24dB/oct Analog Low Pass Filter)
A digital dynamic low-pass filter with
characteristics similar to a 4-pole analog synth
filter.
Resonance
LPF18 (18dB/oct Low Pass Filter)
3-pole 18dB/oct low-pass filter.
LPF18s (18dB/oct Staggered Low Pass Filter)
3-pole 18dB/oct low-pass filter. This filter has a
smoother cutoff slope than the LPF18 type.

LPF12 (12dB/oct Low Pass Filter)
12dB/oct low-pass filter. This filter is designed to
be used in conjunction with a high-pass filter.
Resonance
LPF6 (6dB/oct low-pass Filter)
1-pole 6dB/oct low-pass filter. No resonance. This
filter is designed to be used in conjunction with a
high-pass filter.
HPF24D (24dB/oct Digital High Pass Filter)
