Noise Engineering Cursus Iteritas Magnus

Orthogonal function wavetable oscillator with spectral harmonic shaping

10 HP Eurorack module

Cursus Iteritas Magnus is a dynamically generated wavetable oscillator that uses orthogonal function sets (Fourier, Daubechies wavelets, and Walsh functions) to give spectral-like control over harmonic content. It offers bandpass-filter-style controls over timbre — Center, Width, and Tilt — allowing asymmetric spectral shaping with a strongly musical, harmonic tone structure. It is the 5U large-format version of Cursus Iteritas and excels as a lead, bass, or textural oscillator.

Features

  • Three orthogonal function modes: Fourier (sine), Daubechies (wavelet), Walsh (sequency)
  • Dynamically generated wavetable rebuilt in real time from spectral description
  • Bandpass-filter-style spectral controls: Center, Width, Tilt, Structure
  • Variable sample rate locked to a multiple of the fundamental frequency to align aliasing with harmonics
  • Edge control interpolates oversampling from point sampling to cubic-spline (NURBS) interpolation
  • Fold wavefolder for additional harmonic complexity
  • Analog-style soft clipping stages throughout signal path for warmth
  • Wavetable normalization reduces amplitude variation across spectral changes
  • 1V/oct pitch tracking with encoder for fine and coarse tuning
  • Two-octave Range offset switch
  • Edge-based oscillator hard sync input
  • CV inputs for all major parameters: Pitch, Center, Structure, Edge, Fold, Width, Tilt

Controls & Jacks (22)

  • Pitch— Controls the base pitch of the oscillator.
  • PITCH— 1V per octave pitch control. Turn encoder for fine tuning, press and turn for coarse tuning.
  • EDGE— Controls the oversampling filter of the wavetable. Turning right adds musical overtones. Functions as offset for Edge CV input.
  • TILT— Weights the spread of harmonics. Middle is symmetric; left emphasizes lower harmonics; right emphasizes higher harmonics. Functions as offse
  • TILT— Weights the spread of harmonics. Middle is symmetric; left emphasizes lower harmonics; right emphasizes higher harmonics. Functions as offse
  • PARITY— Controls the harmonic parity/distribution of the oscillator.
  • OUTPUT— Main audio output.
  • CENTER— Selects the center harmonic used to build the wavetable. Functions as offset for Center CV input.
  • WIDTH— Controls how many different harmonics are used to create the wavetable. Functions as offset for Width CV input.
  • B/A/T— CV input for the Bend/Add/Tilt parameter.
  • CENTER— Selects the center harmonic used to build the wavetable. Functions as offset for Center CV input.
  • PARITY— CV input for the Parity parameter.

  • FOLD— Wavefolder control. Functions as offset for Fold CV input.
  • WIDTH— Controls how many different harmonics are used to create the wavetable. Functions as offset for Width CV input.
  • EDGE— Controls the oversampling filter of the wavetable. Turning right adds musical overtones. Functions as offset for Edge CV input.
  • FOLD— Wavefolder control. Functions as offset for Fold CV input.
  • B/A/T— Switch selecting between Bend, Add, and Tilt waveshaping modes.
