FLTRS

FLTRS by MNTRA Instruments is a creative filter ecosystem that puts 37 legendary analog circuit models and experimental physics engines under your hands. Rather than static digital approximations, its Anima Circuits technology models the physical behavior of components, so filters warm up, self-oscillate and sing without harsh digital clipping when pushed. Three XYZ macro axes give immediate control, while an envelope follower and AniMod keep the effect feeling performable. Use it to add character to sterile soft synths, reshape drum buses, or animate vocals. Because the DSP is CPU-efficient, you can stack multiple instances in series between delays and reverbs, building a modular processing chain inside your DAW. It suits hobby producers and sound designers who want expressive, hardware-inspired filtering with room to experiment, from warm Moog-style drive to gritty Soviet tones and shimmering spectral textures.
