Noise Engineering Loquelic Iteritas

Dual-pitch digital VCO with three radical synthesis algorithms

10 HP Eurorack module

Loquelic Iteritas is a complex digital VCO featuring three classic synthesis algorithms — VOSIM-inspired, summation synthesis, and phase modulation — each with dual independent pitch oscillators. It excels at producing a massive range of timbres from calm sine-based tones to harsh, broken, industrial textures. The module prioritizes tonal variance and continuous sound morphing over strict musical pitch accuracy.

Features

  • Three classic synthesis algorithms: VOSIM-inspired (VO), Summation Synthesis (SS), and Phase Modulation (PM)
  • Dual independent pitch oscillators (A and B) each with 1v/Oct input, coarse and fine knobs
  • Pitch inputs are cross-normaled to each other by default
  • Four tone controls: Morph (waveform), Fold (wavefolder threshold), Modulate (phase modulation), Damp (algorithm-specific parameter)
  • All four tone controls have dedicated CV inputs
  • Morph continuously varies waveform between sine, triangle, and saw
  • Wavefolder on output stage for additional harmonic content
  • Master sync switch: free-running, A syncs B, or B syncs A
  • Unique multisampling technique using irregular interleaved sample rates to make aliasing more musical
  • Intentionally naive algorithm implementations that include interesting harmonic artifacts
  • AC-coupled audio output
  • 10HP Eurorack format
