FilterCult

Overview

FilterCult is a powerful, creative signal filtering and sound coloration tool. This multi-device effects processor is composed by a set of modeled analogue gears and digital devices, arranged inside a rack-mount cabinet and accessible through a simple and easy to use interface.

At its heart, FilterCult consists in an accurate simulation of the infamous and iconic transistor ladder analogue filter, meticulously preserving its original circuit topology, behaviour and quirks. Moreover, the addition of circuit-bending modifications and the possibility to use supplementary nonlinear electronic components sensibly expand its sound sculpting possibilities.

As a master effect or as a single channel insert processor, FilterCult is always the right choice in any music production scenario, producing from smooth and gentle analogue filtering up to extremely aggressive colorations of any audio material.

The Good, The Bad, The Nasty

Playing the leading role in FilterCult is the FLT-TL22 device, an accurate modeling simulation of a transistor ladder analogue filter. In order to make this analogue filtering unit well-suited for a wide range of use cases, a meticulous preservation of the original circuit design and physical properties was just the beginning.

A series of experimental circuit-bents and improvements have been added, including a device-level feedback path (with the possibility to delay the feedback signal), extra pre-filter and post-filter nonlinear components (using transistor-based or tube-based technologies), a poles selector (by connecting different nodes of the analogue circuit to the main device output), a high-pass path and much more.

Moreover, FilterCult rack hosts additional devices. The PRM-EM44 unit is an easy to use input signal router, output signal mixer.

Controlling the analogue filter cutoff and emphasis (resonance) parameters, the MOD-XG01 unit is a multi-source modulation device, integrating an envelope generator, a multi-waveform LFO with tempo-sync and a noise generator.

This extended features set makes FilterCult perfectly suited for use in channel strips or as a master effect processor, filtering the incoming audio with its gentle analogue touch, drive and presence. Or, by rising up the internal nonlinear components operation, feedback paths, self-oscillation and modulation amounts, FilterCult is capable of deep and wild signal alterations, bringing powerful electric-esque, bassline-ish colorations - specially on rhythmic, percussive material like drums.

FilterCult is a complete, extended replica of one of the most great sounding and versatile analogue filters available - with a very lightweight CPU footprint and a simple, intuitive interface.
