The MCFx2 is our state variable ‘MCF’ filter made double. It features 2 identical classic analog 3 pole filter cores each with Low, High and Band Pass (or Notch) outputs. Direct and voltage control is provided for both filter cut offs and resonance.

‘MUM M8’ is an 8hp Eurorack low pass filter building on the filter design used in the classic Akai S950 12 bit sampler with the addition of resonance, voltage control, clipped saturation and a dedicated VCA.

The Erica Synths Black 3109 VCF/VCA is a lowpass filter and voltage-controlled amplifier combo built around the AS3109 VCF integrated circuit, a contemporary version of the IR3109 chip, found on vintage Roland synths such as the Jupiter series, Juno series and the SH-101.

Erica Synths Black Dual VCF is a dual multimode filter with CV control over cutoff and resonance for serious modular patches.

Erica Synths Black LPG is our take on Lowpass Gate idea – it’s designed from scratch featuring 2nd order lowpass VCF (the original Buchla lowpass gate was 1st order VCF) and VCA combo with distinct resonance circuit on top.

 Erica Synths Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian synth the Formanta Radio Factory Polivoks.

As its name suggests, the Erica Synths DJ VCF STEREO module provides sound treatment functionality typically found on DJ decks – it is fully open when the cutoff knob is at 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated.

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.
