About Filter Types
LPF (Low Pass Filter)
This is a Filter type that only passes signals below the Cutoff
Frequency. The sound can be brightened by raising the cutoff
frequency of the filter. On the other hand, the sound can be
darkened by lowering the cutoff frequency of the filter. You can
produce a distinctive "peaky" sound by raising the Resonance
to boost the signal level in the area of the Cutoff Frequency.
This filter type is most popular and useful for producing classic
synthesizer sounds.
LPF24D
A dynamic 24 dB/oct low-pass filter with a characteristic digital sound.
Compared to the LPF24A type (below), this filter can produce a more
pronounced resonance effect.
Level
These frequencies are
"passed" by the filter.
Cutoff Frequency ( )
LPF24A
A digital dynamic low-pass filter with characteristics similar to a 4-pole
analog synthesizer filter.
LPF18
3-pole 18 dB/oct low-pass filter.
LPF18s
3-pole 18 dB/oct low-pass filter. This filter has a smoother cutoff slope
than the LPF18 type.
HPF (High Pass Filter)
This is a Filter type that only passes signals above the Cutoff
Frequency. You can then use the Resonance to add further
character to the sound.
HPF24D
A dynamic 24 dB/oct high-pass filter with a characteristic digital sound.
This filter can produce a pronounced resonance effect.

HPF12

BPF (Band Pass Filter)
This Filter type is a combination of a LPF and HPF. When this
Filter Type is selected, you can set the Cutoff Frequency
around which the audio signal is passed.
BPF12D
The combination of a -12 dB/oct HPF and LPF with a characteristic
digital sound.
