6.3. Saving and Rating Gems

After placing and auditioning a strong pair, right-click the destination Mix row and choose Save Incoming Transition as Gem. The saved direction is the preceding source track into that destination track.

A Gem explicitly authorizes that exact directed harmonic edge even when the general transition profile would reject it. BPM, Allowed Keys, uniqueness, and other non-harmonic constraints still apply. Saving source → destination never implies destination → source.

Gem ratings use the same 1-5 star language as track ratings. Click a star to set the personal rating, click the current star again to clear it, or choose Unrated from Personal Rating. A higher rating may increase preference between otherwise feasible choices, but it remains separate from detector evidence.
