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
