Arp Omni-2

Released in 1978

The Arp Omni-2 took the same great architecture of the original Omni and placed it inside a sleek all-steel chassis. Along with new envelopes, the Omni-2 also employed Arp's new concept of "Tri-Phonic", where each section (Strings, Synth, and Bass) was given it's own dedicated output.
