Virt Iter Legio is a three-algorithm stereo oscillator with stereo phase modulation inputs and a
vintage-inspired chorus. Astute users may recognize the oscillator algorithms – Bass, Harm, and
SawX – from our contributions to the Arturia Microfreak and from our Virt Vereor plugin.
Its simple interface and unique, immersive sound make it a staple for any style of sound design. Use
the hard sync input to add an aggressive edge to sounds when synced to another oscillator, or try
patching VIL's left and right phase modulation inputs independently for even further sonic
exploration in the stereo field: trust us, stereo 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.
Etymology
Virt -- from Latin: "strength"
Iter -- Iteritas -- from Latin: "repeat"
Legio -- from Latin: "legion, army"
"Army of strong repetitions"
Color code
On boot, the VIL's LEDs will shine with this color
pattern to indicate that it is running the current VIL
firmware:

    Noise Engineering or an authorized retailer (receipt or invoice required). The cost of shipping to Noise Engineering is paid by the user. Modules requiring warranty repair will either be repaired or replaced at Noise Engineering's discretion. If you believe you have a product that has a defect that is out of warranty, please contact us and we will work with you.
  • Page 3 Input and output voltages Virt Iter Legio’s CV-modulation inputs expect signals from 0v to +5v. The Pitch input’s range is -2v to +5v. The Sync input responds to a rising edge around +1.6v. The phase-modulation inputs are AC coupled and respond to any Eurorack audio signals.
  • Page 4 Patch Tutorial Drone Virt Iter Legio can be used as a simple drone oscillator: simply monitor the L and R outputs, try out the different settings, and move the parameters by hand or with Voice Patch the Virt Iter Legio’s outputs to two VCAs. Mult the output of an envelope generator to the CV inputs of your VCAs.

    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 been in some stage of development ever since, and we regularly received questions about its release without being able to give any sort of definitive answer due to manufacturing and development hurdles, and parts shortages.

    Calibration Virt Iter Legio features extremely accurate pitch tracking and an autocalibration system. You’ll never need to manually adjust pitch tracking: power the unit on with nothing patched to the pitch CV input and the module will calibrate itself during startup.
