Filter Type
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.
