ReBirth For IPad
ReBirth was an application initially created for Mac back in late 1996, and emulated two Roland TB-303 synthesizers, a Roland TR-808 drum machine, and a Roland TR-909 Rhythm Composer simultaneously. These devices were all created in the early 1980s, and their sound has been replicated extensively in hip-hop, house, techno, and other music genres. ReBirth received a "rebirth" of sorts this year when Propellerhead Software, the Swedish company that published ReBirth through 2005, revived the classic software with a ReBirth iPhone app ($6.99).
