Filtron is a 12dB state variable filter that can smoothly transition between lowpass, bandpass, and highpass. It is capable of self-oscillation with resonance levels that can reach up to 11! Filtron also features a fat sounding internal saturation algorithm and a sizzly post overdrive with two modes to choose from: cold and hot.
Supports VST2 / VST3 / AU / AAX plug-in formats
For Windows 64bit and OSX 10.13+ 64bit

Filtron’s parameters can be modulated via sidechain by CV generators such as Gatekeeper. Each channel in a stereo pair is treated as a separate modulation source and can be split to stereo. Filtron is also optimized for audio rate modulation.
Filtron’s internal saturator has a warm soft sounding curve. The filter sounds different depending on the input level.
It also has a powerful overdrive on it’s output, with two modes: cold – a screaming overdrive for those TB-303 riffs
hot – a warm and fuzzy overdrive for the rest 😉
Experiment with Filtron in your effects chain today!
Filtron’s parameters can be modulated by the side chain signal. This allows for Control Voltage or “CV” type signals such as LFOs and Envelopes, to control the parameters of the plug-in.
It is possible to generate CV signals with modular synthesizers (there are some great free ones), or specialized CV generators such as Gatekeeper.
Filtron was in fact designed to be the perfect companion for Gatekeeper.
“Ok the combo of audio rate and stereo modulation sold me, don’t see that too often!“
“With a resonant high pass set up with a little drive I was able to get a very meaty kick drum using Filtron, it’s useful for more than just filter sweep effects, though it does those very well.”
“So, when a freeware filter like Polyverse Filtron shows up, you can bet that I’ll stop whatever I’m doing and download the plugin instantly.”
