Why Do Some Beats Stop After 20 Seconds?
Your purchase of Drum Beats+ v4 for iOS includes over 100 beats as part of your Standard Library.
Also included in your library are previews for over 250 Pro add-on beats in many more styles. Pro beats are indicated by the ⚡️ graphic and will stop playing after 20 seconds.
While the pro add-on will expand your library significantly, it is optional. To get the full collection, tap the gold button at the bottom of your app after a preview ends.
