6.2. Candidate Selection and Placement

The first query requires the exact selected root and mode. Fewer broadens the search to same-root analyzed modes that contain the complete chord, then removes one non-root chord tone at a time. More reverses those steps and eventually restores exact root-and-mode matching.

Potential Gems include unused Library tracks that satisfy the active Mix BPM rule, Allowed Keys, matching scope, and start/end relationship requirement. Mix groups and exclusions do not hide Gem Finder candidates; this keeps the ear-led search broader than automatic generation.

Exact selected-key realizations rank first. Within otherwise-close results, higher personal ratings surface earlier and each rated row shows its star count. For relaxed results, selecting a candidate updates the displayed incoming mode while keeping the chord root and currently required pitches intact.

Place the candidate after the source track, or replace the existing next track. Placement locks the directed pair and records its local harmonic approval for that Mix. It does not save a Gem, approve the reverse direction, or relax BPM and Allowed Keys.
