Synthrotek - DIRT Filter

A rather radical and unapologetic effect module than a filter. The DIRT has a tendency to distort things and generates sounds you'd rather expect from ring modulators or wave shapers.

DIRT is a lowpass filter with a slope of 12dB/octave and you will find the usual controls for cutoff frequency and resonance. The Bias parameter causes the DIRT to generate interesting and unique effects, similar to ring modualtion and brutal wave shaping. It adds a lot of harmonics, squares up signals. It can even process external, pre-amplified audio.
