Rhodes Chroma

The Rhodes Chroma, originally developed as the ARP Chroma, is a polyphonic, multitimbral, microprocessor-controlled analog synthesizer designed by ARP Instruments, Inc. in 1979–1980, shortly before the company's bankruptcy in 1981. The design was purchased by CBS Musical Instruments and put into production by its Rhodes Division in 1982 as the Rhodes Chroma at a list price of US$5295. Rhodes also released a keyboardless version of the Chroma called the Chroma Expander (US$3150).
The Chroma was one of the early microprocessor-controlled analog synthesizers. It was designed before MIDI and featured a 25-pin D-sub connector for computer communication and Expander linking. An Apple IIe interface card and sequencing software were also available.
Production ended in 1984 after an estimated 1400-3000 Chromas and Expanders were built.
