Is Arp a different company from Korg?

ARP Instruments, Inc. was a company founded in 1969. They produced some iconic synthesizers which were popular with some legendary keyboard players including Elton John, Herbie Hancock, Jon Lord, Jean Michel Jarre and Kraftwerk. ARP eventually went on to surpass Moog as the world's leading electronic musical instrument manufacturer until they tragically closed their doors in 1981 due to financial difficulties. Over 30 years later, Korg worked closely with ARP Instruments co-founder David Friend to develop their reinterpretation of the original Odyssey, a project which has been extremely well received.
