Chiral didn't invent these mechanisms, it implemented them. Follow the thread from the original discovery to the plugin it became, and read the paper or run the lab at each stop. For how this catalog sits in the wider landscape of science-based music software, read the field guide.
Following a boat's bow wave on horseback for two miles, Russell watches a single heap of water hold its shape. The founding observation of soliton theory, sixty years before the equation that described it.
Verhulst's curve describes a population that accelerates, then saturates against its carrying capacity. Autocatalysis runs sixteen resonators on that law, harmonics that bloom, compete, and self-limit without ever clipping.
Boltzmann gave disorder a temperature. The instrument sequences pitch by that distribution: cold sits near the ground state in a tight motif; heat the system and it scatters into high-entropy melody, every state a valid phrase.
Arrhenius fixed how reaction rate depends on temperature: a larger fraction of molecules clears the activation barrier as the system warms. Arrhenius gates audio events by that same factor, so a single Temperature control sets how often the instrument fires, from a frozen, sparse loop to a dense, boiling one.
Dispersion and nonlinearity, set against each other, produce a pulse that propagates without spreading. Soliton's eight dispersion stages and saturator recreate that balance, so each repeat reshapes itself instead of smearing.
Solved from a trench within months of Einstein's field equations, the Schwarzschild metric sets a clock rate at every radius. Geodesic places delay taps at radii: near taps redshift and slow toward a frozen horizon, far taps keep their time.
Cool a liquid faster than its structural relaxation time and disorder freezes in as glass rather than settling into the ordered crystal. Tool's fictive temperature records that cooling trajectory, not the instantaneous reading on the thermometer. Anneal gives every patch the same memory: quench it and the same knob position yields 17.3 cents of frozen disorder, anneal it slowly and it settles to a 0.95-cent crystal.
Anderson showed that disorder can trap a wave in place rather than scatter it onward. Anderson Freeze raises spectral disorder until a sound localizes and stands still, a freeze with no loop point, held by a quantum-Zeno hold.
Past a critical coupling, a population of oscillators with different natural frequencies synchronizes. Foxfire turns that phase transition into a chorus that drifts, locks, and breaks apart, the order parameter made audible.
Chemotaxis (gradient-following), Lattice (crystalline reverb), Hysteresis (magnetic memory), and more candidate phenomena are being tested against the same standard: does the equation map cleanly onto sound?
