Stereo resonant multimode filter with wavefolding, 1v/8va tracking, and gateable bypass
Roucha Legio is a 12 dB /octave state-variable stereo multimode filter available on the Legio DSP+oscillator platform.
We’ve gotten tons of requests for NE filters over the years, and Roucha Legio is our first dedicated release. The filter features lowpass, bandpass, and highpass settings and tracks frequency via the dedicated encoder and extremely accurate 1v/8va CV input. Roucha Legio’s CV-controlled resonance parameter can go from clean to acidy-squelchy for bassline joy. Add CV for filter sweeps that will knock your socks off. Of course, because it’s a Noise Engineering module, there’s a Fold knob. Add wavefolding to the signal chain before, after, or both before and after the filter.
We really like dramatic buildups and cuts, so we made it easy with Roucha Legio. Just tap the encoder to bypass; tap again to turn the filter on again. Want to automate it? Send a gate into the Bypass input. The filter will remain bypassed as long as a high gate is present.
Roucha Legio is part of the Legio stereo DSP platform. A simple USB connection lets you swap between a variety of oscillator and utility firmwares for free. Try them now at the Firmware Swap app.
