µVCF

A David Dixon state variable filter in 6 HP with three outputs at once: a 2-pole low pass, a 2-pole high pass and a 1-pole band pass. It tracks 1 V/octave and, at full Q, sings as a low-distortion sine VCO.

Key features

• LPF, BPF and HPF outputs at the same time
• FM1 tracks 1 V/octave over 4+ octaves with its attenuator fully clockwise
• FM2 through a bipolar attenuator
• Sine waves from 2 Hz to 20 kHz at full Q
