Roucha Legio is Noise Engineerings’ first dedicated filter, and it’s a 12dB/Oct stereo multimode filter with wavefolding and a gateable bypass.

How has Noise Engineering never released a filter module before? Well, this looks great, and maybe it was worth the wait. Roucha Legio features switchable lowpass, highpass and bandpass modes. The Resonance can build up some pretty sweet oscillations and is completely trackable via a 1v/oct input over 8 octaves. The resonance is also CV controllable.

To be true to the core of Noise Engineering, it has to have a wavefolder, which it does. You can decide whether the folding begins before or after the filter or, why not both?

But the most brilliant feature is the bypass. It doesn’t sound very exciting, but it’s something that’s so often missing in Eurorack, the simple notion of being able to turn something off without having to repatch. The encoder at the top that deals with the cutoff frequency can be clicked to bypass the filter. Or, you can use the Bypass CV input to gate it on and off.

It sounds phenomenal – check out the video below.

Being part of the Legio platform means that you can swap firmware with any other Legio module for free.

    Wouldn’t Viol Ruina be a first filter from NE? Considering Roucha also has extra features like wavefolding they’re both hybrids in that sense.

      Dunno, that’s just what Noise Engineering said – first dedicated filter.

      Viol Ruina was technically our first filter, but being part of our Ruina distortion line it had a lot of features that brought it well out of the range of pure filtration. In a lot of patches, it added more than it took out! Roucha Legio has more traditional filter-specific features (as well as some unique twists, as you’d expect) so we feel like it’s our first offering with filtration as the core concept of the design.
