9.3. Trial and License Changes

Open About to start the standard APU Pro trial or activate a license. The trial unlocks the same local features as paid Pro and does not require a payment card.

If Pro becomes active while a non-empty Community Tracklist Preview is open or finishing, Harmonic DJ saves that preview as its own named Mix and leaves the previously open saved Mix intact.

When a trial expires or a license becomes inactive, Harmonic DJ returns to Community. The Library, Gems, shared collections, transition presets, and Mix documents remain stored. Existing Pro work stays readable and auditionable while Pro-only creation and editing actions are unavailable.

If Pro access changes during a long generation, Harmonic DJ leaves the existing saved Mix unchanged rather than committing a partial result.
