Free Music Software: Polyverse has introduced Filtron, 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 an internal saturation algorithm and post-overdrive, with two modes to choose from: cold and hot.

Filtron’s parameters can be modulated via sidechain by CV generators such as Polyverse’s Gatekeeper. Each channel in a stereo pair is treated as a separate modulation source and can be split into stereo. Filtron is also optimized for audio rate modulation.

Availability:

Filtron is available in VST2, VST3, AU, and AAX formats, making it compatible with a variety of host applications including Ableton Live, Logic, Pro Tools, Cubase, Reason, and Studio One. It can be used in 64-bit instances with Windows 7 and up, as well as Mac OS X 10.13 and up (intel and apple silicon).
