8.3. Mix and Preset Files

A .hdjmix file contains the current Mix document: its track references, order, roles, locks, exclusions, target values, key profile, transition-profile snapshot, rules, authored incoming-transition explanations and context, sharing details, and other planning state. It does not contain audio, private undo history, or the live association with a published Mix page. Importing the file creates a new local Mix identity, so it cannot update or advertise the source Mix’s published page. Duplicate Mix follows the same rule.

Exported transition presets contain a reusable transition profile. Applying one copies that profile into the active Mix; the Mix does not depend on the preset file remaining available later.

Mix import and export, along with transition-preset management, are available in Community. Imported Mixes remain readable and auditionable there; Pro is required to edit them as durable Mix documents. Imported Mixes and presets are validated before replacing local state. Keep exports alongside normal project backups when a tracklist or custom relationship is important.
