If you have a DDJ-1000, you get access to hardware unlock.
The DDJ-1000 supports DVS, but as that's not a core function of that unit, if you want to use it, you would need a subscription. Likewise for any of the other advanced features found in the Creative plan.
Our intention is to continue to provide new and innovative features for the rekordbox ecosystem without having to charge customers an additional fee for an upgrade or add-on. You will continue to get access to the core functionality with your hardware without the need for a subscription, but if you want the additional features, that will require a subscription.
