The Noise Engineering Loquelic Iteritas (Black) is an Oscillator Module for Modular Synthesizers in Eurorack Format. It has 2x Digital Oscillators, one of which can be set as a Master by the Toggle Switch. However, the Module is not an ordinary Digital Oscillator, but rather a Comb Oscillator that offers Vocal Synthesis, Sum Synthesis and Phase Modulation with Variable Waveform. A Toggle Switch is also used to switch between the Synthesis Forms. For further processing of the sound, a Wavefolder and the CV-Controllable Parameters Modulate, Morph, Damp and Pitch are available for both Oscillators.
