Epilogue VCF

Filter after a Korg synth's, with overdrive

Nonlinearcircuits · 8 HP · 3U

Panel · 40.6 × 128.5 mm

Description

Inspired by the VCF of a defunct Korg synth, after Victor Lazzarini's article on it, but no clone: its CV, resonance and overdrive circuits differ, the resonance under a VCA and the overdrive roughened with an LED. O/DRIVE mixes the low-pass and the overdrive; LO CUT trims the low frequencies, not quite a high-pass. Keep the IN 1 knob up.

Key features

  • IN 1, IN 2, FR CV and Q CV in; LP, LO CUT and O/DRV out
  • FREQ, Q, FR CV, Q CV, IN 1 and O/DRIVE knobs
  • 8 HP; Nonlinearcircuits publishes no current draw, depth or assembled price (it sells the DIY PCB and panel), and ModularGrid lists none
