Filtron is a cutting-edge 12dB state variable digital filter designed to deliver smooth transitions between lowpass, bandpass, and highpass modes. It offers powerful self-oscillation capabilities with resonance levels reaching up to 11, providing rich and dynamic tonal possibilities. The filter's zero delay design and internal oversampling ensure pristine sound quality and responsiveness, making it a reliable tool for both subtle and dramatic filtering effects.

The internal saturation algorithm adds warmth and character to the sound, producing a fat and full-bodied tone. On top of this, Filtron features a versatile post-overdrive section with two distinct modes: cold, which delivers an aggressive, screaming distortion ideal for acid basslines, and hot, which offers a warmer, fuzzier overdrive suitable for a variety of musical styles. This combination of saturation and overdrive enhances the expressiveness and depth of any audio source.

Filtron supports stereo modulation through control voltage sidechains, allowing each channel to be modulated independently or split across the stereo field. It integrates smoothly with CV generators and is optimized for audio-rate modulation, expanding creative sound design possibilities. Available completely free, Filtron is a powerful and flexible filtering solution that fits seamlessly into modern music production workflows.
