Anderson Freeze^™

Disorder is the freeze knob.

Anderson localization is the result that waves in a disordered medium stop propagating and trap themselves in place, decaying exponentially over a localization length ξ. Anderson Freeze builds that directly. Disorder detunes the per-band loops, the bands stop moving, and the spectrum sits. Because shorter wavelengths localize at lower disorder, the high end freezes first and the freeze sweeps down the spectrum, exactly as the mobility edge does in the physical system.

• Disorder sets the freeze.

  One control detunes the per-band feedback loops. Low disorder lets the spectrum keep moving; raise it and the bands lock in place. Everything between sustain and full freeze is a continuous, automatable setting, and the high end freezes first as the mobility edge sweeps down.

• Two physics, two sounds.

  Localization freezes by trapping each band's feedback. Zeno freezes by observation, re-sampling a micro-snapshot at a measurement rate so the state cannot evolve. The same source held two ways, by two different mechanisms.

• A freeze that breathes.

  Sync drives a tempo-locked refresh through a level-conserving crossfade, so the frozen bed re-captures in time instead of sitting as a dead static pad. Pulse Depth sets how far the bed moves on each pulse; the Division sets the grid.

• Crystal shapes the bed.

  Five density-of-states curves set how energy distributes across the frozen band, from a flat shelf to a sharp resonance. The curve you pick changes the timbre of what localizes, not just its level.

• Capture you can time.

  Freeze and Clear are the hero gestures. Arm captures on the next transient instead of on the press, so the freeze lands on a hit rather than between them. Harm pins the held spectrum to a chosen Root and Chord.
