Arp

Arp Instruments, Inc. was an American manufacturer of electronic musical instruments, founded by Alan Robert Pearlman in 1969. Best known for its line of synthesizers that emerged in the early 1970s, ARP closed its doors in 1981 due to financial difficulties. The company earned a reputation for producing excellent sounding, innovative instruments and was granted several patents for the technology it developed. In 2015, the ARP Odyssey was revived by Korg.
