Filters - Resonators

'Ivo' is a resonant low-pass VCF (Voltage Controlled Filter), switchable between 2-pole (12dB/octave) and 3-pole (18dB/octave) responses, with voltage control over feedback (resonance) as well as cutoff frequency. It will self-oscillate in 2-pole mode.The module has two audio inputs, one with an att..

Mr. Phil Ter isn’t the smartest name for a module that has an envelope generator, VCA, and a filter in it. Well, we never claimed to be smart. Mr. Phil Ter, or Phil as we affectionately call it, is a module that does a whole bunch of analog and digital stuff, in not a lot of HP. Phil’s digital bits ..

Eurorack-extention for Mono Lancet and Mono Lancet ’15Mono Lancet ’15 is compact and versatile. It has two high-quality oscillators and a classy lowpass filter. Wouldn’t it be great having these components in your eurorack modulars system?That’s where Modular Dock comes into play. It routes various ..

HumpbackA fat 2-pole state variable filter which invokes the classic sounds of the synthesiser 'golden years', twisted and mutated to reflect the future. Multi-mode, state-variable topology and 'hot-rodded' resonance for self oscillation. Humpback is made with high quality components including silve..

Gem FiltersGem Filters are small profile four-pole filters available in either low-pass or high-pass packages. These tiny powerhouses provide classic four-pole sounds and are made with high-quality components including silver mica capacitors - GEM filters pack a huge sound in a tiny package!Behind t..

Noise Engineering’s take on the classic autowah, in stereo, and with a twistLacrima Versio's roots are in the classic analog autowah pedals, but we don't stop there. LV features an envelope follower that controls a high-resonance filter. Morph the filter between lowpass, bandpass, and highpass ..

DESCRIPTIONZagrzeb is a stereo multimode 4-pole (24dB/oct) state variable voltage-controlled filter (SV VCF). It offers five distinct frequency responses, three of which are available simultaneously. Zagrzeb is designed to sound smooth and clean unless it is overdriven with a hot signal—however, it ..

MCFx2 is our state variable ‘MCF’ filter made double. It features 2 identical classic analog 3 pole state variable 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. Switches allow the filtersto function as..

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.Features24dB/oct lowpass VCF..

Stereo Multimode FilterModule A-121s is a dual multimode filter which can be used for stereo applications as well as for parallel or serial organized dual mono filters. The core is a 12dB multimode filter identical to the modules A-121-2 and A-121-3. The selection of the filter type is continuously ..

The Spectral Multiband Resonator from 4ms Company is an innovative resonant filter which can process audio like a classic filter bank, ring like a marimba when plucked/struck, vocode, re-mix tracks, harmonize, output spectral data, quantize audio to scales, and much more...A gorgeous ring of colored..
