The Little Filter That Could
Introducing the µVCF state variable filter, another great David Dixon filter design. It is a very clean and precise filter that also doubles as an excellent sine VCO.
It responds excellently to FM and the small size makes it a nice choice for smaller system.
Features
- 2-pole Low pass (LPF), 2-pole High pass (HPF) and 1-pole Bandpass outputs (BPF).
- FM1 input acts as 1V/Oct when fully clockwise and tracks accurately over 4+ octaves
- FM2 input has a bipolar attenuator.
- At full Q the output produces very low distortion sine waves with a range of 2Hz to 20kHz.
