Erica Synths - Fusion VCF V3

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.
Features

    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
