Noise Engineering Intros Legio Oscillator & DSP Platform

Noise Engineering has introduced the Virt Iter Legio oscillator/DSP platform for Eurorack modular systems.

Their concept for Legio is that it’s a Eurorack hardware platform that can load a wide variety of firmware, making it the foundation of a variety of module types. Anyone with any Legio module will be able to try any firmware for it, for free.

To kick off the line, they’ve introduced two modules:

  • Virt Iter Legio is an oscillator that builds on the synthesis algorithms used for NE’s contribution to the Arturia MicroFreak and their software plugin Virt Vereor.
  • Librae Legio is a dynamics processor, featuring compression, expansion, limiting, noise gating, and two styles of gentle distortion.

“The Legio platform brings the power of a reprogrammable and multifunctional module down to a 6 HP size, perfect for any system,” says NE’s Markus Cancilla. “It’s an exciting development and we’re thrilled to be able to share it with the world!”

Here are the details:

Virt Iter Legio is a stereo oscillator with a distinct and versatile sound. Its three modes – Bass, SawX, and Harm – will be familiar to users of Noise Engineering’s free Virt Vereor plugin or those who have the Arturia Microfreak, both of which are based on the same algorithms.

Virt Iter Legio features independent left and right phase-modulation inputs, a sync input, and a lush vintage-inspired chorus. This small oscillator puts unique sounds right at your fingertips and makes them easy to manipulate within the stereo field. Virt Iter Legio works well for beautiful pads, hard-hitting basses, and leads that can be simple or otherworldly.


  • 6 HP and US$279, available and in stock
  • 3 stereo oscillator algorithms: Bass, SawX, and Harm
  • Independent left and right phase-modulation inputs
  • Vintage-inspired chorus spreads sounds across the stereo field
  • Accurate pitch tracking from -2v to +5v using an automatic self-calibration process
  • Oscillator/DSP platform: change the firmware on your module to a different module on the Librae platform

Librae Legio is a stereo dynamics processor, designed for the master bus with compression, limiting, expansion, and optional saturation.

Librae Legio was designed to work with any type of patch. It’s great for limiting, compression, and expansion. Noise Engineering says they created it to be able to be applied as transparently as possible, but also so that you can crank the settings to really squish your sounds for maximal crunch.

They added a saturation stage that you can engage, if you wish for some slight harmonic distortion: it adds a touch of color and some tape-like effects to louder elements. It’s also CV controllable and works great with mono or stereo signals.

Librae Legio also has a sidechain filter that the user can set to change the behavior of the dynamics processing.


  • 6 HP and US$279, available and in stock
  • Works in both mono and stereo
  • Incredibly clean compression, expansion, and limiting
  • Adjustable noise gate avoids unwanted noise when heavily processing sounds
  • Configurable sidechain filtering changes how the processing reacts to your sounds
  • Optional saturation adds flavor to your mix
  • Oscillator/DSP platform: change the firmware on your module to a different module on the Librae platform

Pricing and Availability

The modules are available now, priced at $279 USD.

  1. i absolutely love Noise Engineering but their module names are so freaking hard to follow. the stereo osc sounds fantastic.

  2. Noise Engineering puts out quality firmware n designs…I trust their stuff. This module looks and sounds great. I’ll probably pick one up.

  3. Wow, that OSC sounds nice!

    I’m a fan of the NE ethos, but sometimes the harshness of the demos turns me off a bit. I’ve owned my share of NE modules, and we all know they can get truly nasty sounding (in a good way) – but I applaud NE for publishing a demo showing the softer side!

    This is now on my list!

  4. Noise Engineering are a great company, they definitely do things ‘there way’ but we need more original thinkers! Their free (and paid) VSTs are also great…keep it up guys!
