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 eight default 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.
Four additional focused presets let you audition transitions with roots a tritone, or six semitones, apart:
- Tritone Intervals keeps the exact detected mode.
- Tritone Progression advances through Ionian → dorian → phrygian → Lydian → Mixolydian → aeolian → Ionian, skipping unsupported locrian on the wrap.
- Tritone Brightening moves through phrygian → aeolian → dorian → Mixolydian → Ionian → Lydian without wrapping.
- Tritone Darkening follows that brightness sequence in reverse, also without wrapping.
Every factory preset retains all twelve editable rules. General Purpose leaves the four Tritone rules disabled; each focused preset enables only its same-named rule. Apply a Tritone preset to test one relationship, or enable selected Tritone rules alongside your preferred existing rules and save a user preset.
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.
