The Split-8 is a polyphonic analogue keyboard synthesizer manufactured by Sequential Circuits. Built in Japan and going by the alternative name Pro-8 in some markets, this was one of the last synthesizers produced by the company and was assigned model number 608. It was released in 1985 at a list price of $1,199 (or $1,195; this number varied between advertisements). This and some other Sequential Circuits synthesizers (the Six-Trak, Multi-Trak and MAX) were built around the Curtis Electromusic CEM 3394 "synth-on-a-chip" integrated circuit, and used a Z80 as their central microprocessor.
