The Sampler With 10 Seconds of Memory That Built Hip Hop

In 1987, a struggling California company called E-mu released the SP-1200: a drum machine with ten seconds of sample memory, 12-bit sound and a floppy drive. Its designers had no idea what New York was about to do with it. Within a few years, producers like Large Professor, Pete Rock, RZA and DJ Premier had turned its limits into the sound of hip-hop's golden era. This is the story of the machine and the people around it: Dave Rossum and Scott Wedge in Santa Cruz, Paul C at Studio 1212 in Queens, Ced-Gee in the Bronx, Pete Rock in Mount Vernon, the 1991 court ruling that changed sampling, and "the product that refused to die". We also show, step by step, what the 2.5-second limit meant: why producers played 33 rpm records at 45, why the SP-1200 sounds the way it does (26.04 kHz, 12-bit, drop-sample pitch shifting), and how chopping turned a couple of seconds of a record into a new song. The music in the listening demos is our own, run through a simulation of the SP-1200's sound chain.
