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.
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).
