5.2. Transition Profiles and Presets

A transition profile is the ordered set of enabled relation rules used to accept directed harmonic edges. The first enabled rule that matches a transition supplies its priority and primary explanation.

General Purpose enables all eight release rules in priority order: Parallel Intervals, Steady Harmony, Parallel Progression, Steady Progression, Parallel Brightening, Steady Brightening, Parallel Darkening, and Steady Darkening. The first four remain the core relationships, the two non-wrapping Brightening rules are lower-priority fallbacks, and the two reverse-direction Darkening rules are the final fallbacks for constrained libraries. The factory catalog also includes a focused preset for each relationship.

Applying a transition preset copies its complete profile into the active Mix without changing the other planning settings or targets. The Mix keeps that snapshot, so later edits or deletion of a user preset cannot silently rewrite an older Mix. Use Mix Settings Presets… for a complete planning setup.

Factory presets are immutable. Pro users can save the active profile as a user preset, then update, rename, describe, import, export, or delete that reusable entry.
