The Rhodes Chroma is a polyphonic, multitimbral, microprocessor controlled, subtractive synthesis analog synthesizer developed in 1979-1980 by ARP Instruments, Inc. just before the company's bankruptcy and collapse in 1981.

Programming was further complexed by a limited implementation of just 2 rows of membrane push-buttons. With few sliders to grab, hands-on control is cut short.
