Moog Ladder
FiltersmoogladderModerate CPU
Characterful 4-pole Moog-style lowpass — cutoff + resonance.
What it does
Resonant 4-pole (24 dB/oct) Moog-style lowpass filter.
Wraps daisysp::MoogLadder (DaisySP-LGPL). Cutoff + Resonance update at audio rate, so both can be modulated.
Parameters
-
Cutoff (Hz)
cutoffCorner frequency in Hz — frequencies above it are rolled off at 24 dB/oct. This number is the value baked in at boot; wiring the Cutoff port overrides it every sample.
-
Resonance
resonanceFeedback around the four-pole ladder, emphasising the region right at Cutoff. Low values add a gentle peak; near 1 the filter self-oscillates into a sine at the cutoff pitch.
The Moog sound — fatter resonance than the Svf Filter. Cutoff/Resonance are the defaults used when a port is unwired; wire a knob into either to sweep at runtime. Resonance near 1 self-oscillates.
