Xhun FilterCult

FilterCult is a powerful, creative signal filtering and sound coloration tool. This multi-device effects processor is composed 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 of an accurate simulation of the infamous and iconic transistor ladder analogue filter, meticulously preserving its original circuit topology, behavior, and quirks. 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. Playing the leading role in FilterCult is the FLT-TL22 device, an accurate modeling simulation of a transistor ladder analogue filter. 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, extra pre-filter and post-filter nonlinear components, a poles selector, 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 and output signal mixer, controlling the analogue filter cutoff and emphasis (resonance) parameters. The MOD-XG01 unit integrates an envelope generator, a multi-waveform LFO with tempo-sync, and a noise generator. This extended feature set makes FilterCult perfectly suited for use in channel strips or as a master effect processor, gently filtering the incoming audio, or capable of deep and wild signal alterations, bringing powerful electric-esque, bassline-ish colorations.

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