svf()

Category

Filter

Description

State-variable low-pass filter. It is useful when you want a cleaner, more controlled low-pass tone than a ladder-style filter while still keeping musical resonance.

Arguments

• input: audio/control signal to process
• cutoff: normalized cutoff control, commonly around 0.0 to 0.5
• resonance: resonance/Q amount

Typical Values

Start with cutoff around 0.03 to 0.30 and resonance around 0.05 to 0.70. Higher values can become sharper and more vocal.

Example

svf(dualsaw(X,0.18), 0.03+0.28*param(2), 0.18+0.45*param(3))

Notes

Use svf() when you want a modern synth-style low-pass that stays articulate under modulation. It works especially well on pads, brass, and cleaner bass tones.
