Noise Engineering Loquelic Iteritas Percido

Three-algorithm digital oscillator with built-in VCA

10 HP Eurorack module

Loquelic Iteritas Percido (LIP) is a complex digital oscillator that generates its sound through three interacting algorithms applied to a base oscillator. It creates a wide range of timbres from pure tones to harsh noise by stacking waveshaping, modulation, and folding operations. The module includes a built-in VCA for complete voice functionality, making it equally suited for melodic lines, pads, and aggressive textures.

Features

  • Three stacked algorithm stages
  • Multiple algorithm sets selectable
  • Built-in VCA for complete voice
  • 1V/oct pitch tracking
  • CV control over all parameters
  • Wide timbral range from pure to noise
  • Trigger/gate input

Controls & Jacks (50)
