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

 

 

Inputs/Outputs:

 

- CUTOFF CV IN = Voltage range changes depending on where CUTOFF knob is positioned. External attenuation will be needed for fine modulation.

 

- AUDIO IN = Audio Input

 

- AUDIO OUT = Audio Output
