Steiner-Parker Filter

The MicroBrute filter is based on the core of the legendary Steiner-Parker multimode filter and has been enhanced to deliver an even wider range of cutoff and resonance. Nyle Steiner himself has validated and approved these enhancements.

An Audio Processor?

MicroBrute allows a return to audio experimentation by giving you the ability to process external sounds through it. This will allow you to process any other sounds like voice, guitar or other synths through the filter, Brute Factor™, and final output stages.

Brutal Potential

Process audio. Sequence analog gear. Give your modular a new LFO and Envelope Generator. Hook up to your DAW and make whole tracks. Hook up to your Drumtracks and play a whole gig. Tiny in size and price, huge in sound, and vast in potential.
