5.4. Allowed Keys

Allowed Keys filters roots and modes independently across the complete Mix. Every root and every supported mode is enabled by default.

A track is eligible only when both its effective start key and effective end key use an enabled root and mode. With pitch-shifted playback, the effective keys include the same target-relative semitone shift used for audition.

These are global membership constraints, not transition rules. Locked positions, Gem Finder placements, and saved Gems cannot bypass them. At least one root and one mode must remain enabled.
