Range
Center frequency of the filter sweep (80 Hz - 3000 Hz)

Quick Tips
- Tempo Sync: Lock LFO to DAW for rhythmic patterns
- S/H mode: The classic 1970s "computer" sound

- Low Q values: Warm, gentle filtering
- High Q values: Synth-like, pronounced peaks
- Sub 1ms latency: Safe for live performance
