The Fusion VCF3 is resonant 24dB/oct lowpass filter of unique design that combines vacuum tubes and vactrols, providing distinct, soft filtering. For more versatility, the independent audio mixer and buffered multiple is incorporated in the module, and, most importantly – a CV recorder that records motion of the potentiometer, so you can design advanced modulation patterns.


  • Full analogue design 
  • Vacuum tube and vactrol based filter circuit. Because of vactrol lag, 
    the VCF will not accept audio rate modulation, the maximum 
    modulation frequency is 10Hz 
  • Input signal mixer with gain 2 for signal overdrive 
  • Buffered multiple for splitting audio and CV signals 
  • Potentiometer motion record unit with CV and gate outputs 
  • Recorded CV multiplication and division
