DIRT is our new 4HP low-pass filter / effect for the Eurorack modular synth platform.

Inspired by one of our favorite 'noisy' filters, the DIRT is an unapologetic filter / effect that produces interesting and unique effects via the Bias knob, accessible from the front panel.

It's not a traditional filter; it's an effects module with filtering, ring mod effects, wave shaping and even outright brutal harmonic distortion.

DIRT likes to square things up a bit, so throw in a triangle, sawtooth, sine or other wave forms for different style effects. Even plugging a guitar (using an external amplification module) into the DIRT produces some great sounds and heavy distortion.

Controls:

• CUTOFF = Cutoff Frequency

• RESONANCE = Increase the Q!

• BIAS = Set the bias correctly or not, the choice is yours
