Hi,
I’m an iOS developer building an app with an use case that needs advanced playback on Apple Music subscription streams, specifically:
• Real-time tempo change (BPM) during playback — i.e., time-stretch with key-lock, not just crossfade.
• Beat-matched transitions between tracks.
From what I can tell, this capability seems to exist only for approved partners and isn’t available through public MusicKit.
Question: What’s the official request path to be evaluated for that restricted partner entitlement (application form, questionnaire, NDA, or internal team/BD contact)? If the entitlement identifier is internal, how can I get my account routed to the right Apple Music team?
For reference, publicly announced partners include Algoriddim djay, Serato DJ Pro, rekordbox (AlphaTheta), and Engine DJ—all of which appear to implement mixing features that imply advanced playback (tempo/beat-matching) on Apple Music content. I’d prefer not to share product details publicly for the moment and can provide specifics privately if needed.
Thanks in advance!
