Inear Display Regressif

Regressif is an audio plugin focused on sound degradation. Combining a multimode filter with distortion, samplerate reduction and bitcrushing effects, it can turn the most innocent sound into a wall of digital noise. Two LFO modules and an additional LFO mixer can then be brought into the mix to further mutilate your audio.

With its clever design, it’s possible to use Regressif as distortion but also as classic filter plugin.
