Opusmodus 4.0.31105 Update

Update: Wave Functions, Monophonic Analysis, and Harmonics

The wave-function system has been substantially revised and extended.

Wave generators now support a clearer and more complete modulation model:

• :fm for frequency modulation

• :am for amplitude modulation

• :phase-scaling for per-sample phase scaling
  This replaces the earlier :modulation keyword.

• :phase-distortion for phase remapping within the waveform cycle
  

These controls are now available consistently across the main wave families, including the generator, additive, modulatory, and half-wave functions. The Pulse family has also been completed and brought into line with the rest of the system.

The Monophonic Analysis system has now been completed as a full function family, with consistent documentation in the new Markdown format. The analysis set is organised as a unified analytical environment, allowing rhythmic, melodic, harmonic, cadential, formal, textural, density, expressive, and related perspectives to be read together within a single report structure.

To test the analysis functions, download the file below and place it in the ~/Opusmodus/Media/Musicxml folder. This will allow you to evaluate the examples in the documentation directly.

The harmonics function has also been enhanced. Its coefficient behaviour now follows the correct spectral model, rather than simple post-scaling, and the function now supports additional control over partial selection, including patterned partial-nth input and the new :size option for result-length handling.
