ReBirth for iPad (v1.1), a digital emulation of the classic RB-338, features two TB-303s, TR-808, and TR-909 drum machines with Audiobus support and WIST sync. The app was officially removed from the App Store on June 15, 2017, due to a request from Roland regarding intellectual property rights. As a 32-bit application, version 1.1 is incompatible with modern iOS devices and is now largely sought after for use on legacy, jailbroken, or older iPad hardware.
