Erica Synths Fusion VCF3 Eurorack

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. Because of vactrol lag, the VCF will not accept audio rate modulation, the maximum modulation frequency is 10Hz
