The ARP Odyssey was an analogue synthesizer introduced in 1972. Responding to pressure from Moog Music to create a portable, affordable (the Minimoog was around US$1,500) 'performance' synthesizer, ARP scaled down its popular 2600 synthesizer and created the Odyssey, which became their best-selling synthesizer.

The Odyssey was a 2-oscillator analogue synth (compared with the Minimoog which had 3 oscillators) and was the first synthesizer with duophonic capabilities (the ability to play two notes at the same time). All parameters were editable with sliders and buttons.

There were many versions of the Odyssey over the years - shown here is a Mark III.
