  • Page 2 PM is something you’ll want to hear. Turn on the beautiful, wide chorus and you’ll have an endless supply of beautiful sounds. Not only is Virt Iter Legio a fantastic oscillator, it’s also a platform: head to the Customer Portal to swap the functionality of your module to a growing number of alternate firmwares, completely free.
  • Page 3: Color Code

    On boot, the Legio's LEDs will shine with this color pattern to indicate that it is running the current Virt Iter Legio firmware: Power To power your Noise Engineering module, turn off your case. Plug one end of your ribbon cable into your power board so that the red -12 V...
  • Page 4 16 V peak-to- peak Calibration Virt Iter Legio features an autocalibration system. The modules are autocalibrated and tested at the factory, but should you feel you need to recalibrate, just power the unit on with nothing patched to the Pitch CV input.
  • Page 5 18.09.2024, 14:22 Virt Iter Legio - Noise Engineering Documentation II/I/0 Activates the vintage-inspired chorus. 0 is off, I is some, II is lots. Sync Hard-sync input. PM L/PM R Phase-modulation inputs. Intended for use with audio-rate signals for complex harmonic patches, similar in sound to FM.
  • Page 6 18.09.2024, 14:22 Virt Iter Legio - Noise Engineering Documentation Simple stereo voice Patch Virt Iter Legio’s Out L Out R to two VCAs. Monitor the output of the VCAs as a stereo pair. Mult an envelope generator to the input of the VCAs.
  • Page 7 18.09.2024, 14:22 Virt Iter Legio - Noise Engineering Documentation Simple stereo voice with Ampla Versio If you have a Versio module, the Ampla Versio firmware is the perfect stereo dynamics controller for the Virt Iter. Simply patch the Out L...
  • Page 8 18.09.2024, 14:22 Virt Iter Legio - Noise Engineering Documentation Simple PM voice Out L Out R Patch Virt Iter Legio’s to two VCAs. Set VIL to match the settings shown. Monitor the output of the VCAs as a stereo pair. Mult an envelope generator to the CV inputs of the VCA.
  • Page 9 18.09.2024, 14:22 Virt Iter Legio - Noise Engineering Documentation The following patches demonstrate a variety of timbres possible with the Virt Iter Legio. They work well either as drones with the outputs patched directly to your mixer, or with the Simple Stereo Voice patches.

  • Page 12: Firmware Updating

    18.09.2024, 14:22 Virt Iter Legio - Noise Engineering Documentation Firmware updating Virt Iter Legio’s firmware can be updated by the user via our firmware webapp on the Noise Engineering Customer Portal (https://portal. . Alternate firmwares available now transform the noiseengineering.us)
  • Page 13: Tone Generation

    It's a simple algorithm that uses nonlinearities combined with quadrature modulation to produce a variety of tones. The Bass oscillator is based off of this algorithm, with a few Noise Engineering touches (fold anyone?) for more edgy sounds. Flavor controls the saturation of the cos oscillator.
  • Page 14: Design Notes

    Tang knob, phase-modulated noise is mixed into the signal, too. Design Notes Virt Iter Legio was a long time coming. Announced in January of 2020 at NAMM, we were planning to launch soon after but… things happened. VIL has...
