Yay! I used to love Rebirth when it first came out back in the ’90s. Now it’s available for the iPhone. I once played an entire improve set using this on a Pentium Pro at a House party in Madison WI back in ’98.
ReBirth faithfully emulates dance music’s three backbone devices: The Roland TB-303 Bass synth and the Roland TR-808 and 909 drum machines. Combine these with FX units, fully featured pattern sequencers and a quick-acting, scalable iPhone interface and you’ll soon be making techno on the train, trance on the tram or beats on the bus.
