Smule has announced their new Smule Pass service for unlimited access to music and features across several of their music apps. Users of Sing! Karaoke, Magic Piano, AutoRap, and Guitar! can buy a subscription in one app and get unlimited song access and storage, pro studio effects, and the ability to upload Sing! tracks to Smule.com.
Right now, all existing and upcoming purchases of VIP subscriptions in each individual app will get the Smule Pass for all four apps for the life of their subscriptions. It's not possible to purchase a "Smule Pass" per se - we've reached out for clarification on how future purchases will work.
Update: According to a Smule representative, anyone who buys a VIP subscription in an app and has the app linked to their Smule ID will get the Smule Pass, enabling access in the other apps.
