Origins
ARP Instruments developed the Odyssey in 1972 as a direct response to the Minimoog and the growing market for portable, performance-oriented synthesizers. Co-founders Alan Pearlman and David Friend designed an instrument that would offer professional analog synthesis in a more compact and affordable package than ARP's semi-modular 2600. The result was a two-oscillator duophonic synthesizer that became one of ARP's most successful products.
Design & Technology
The Odyssey featured two voltage-controlled oscillators switchable between sawtooth, square, and pulse waveforms with oscillator sync and pulse-width modulation. Its dual-filter architecture allowed switching between a resonant low-pass and a non-resonant high-pass filter. Two envelope generators—an ADSR for the filter and an AR for the amplifier—provided flexible shaping.
The instrument offered duophonic capability, allowing two notes to be played simultaneously—one controlling each oscillator. A sample-and-hold section, sine/square wave LFO, and 'ring modulator' (actually an XOR circuit between pulse waves) expanded sonic possibilities. All parameters were controlled via sliders and switches on a clear, logically arranged front panel.
Three distinct filter designs appeared across production runs: early Mk I units used a two-pole filter similar to Oberheim SEM modules; Mk II models initially employed a four-pole design comparable to Moog's filter before adopting ARP's proprietary 4075 design; Mk III units standardized on the 4075 filter.
Production History
ARP manufactured the Odyssey from 1972 until the company's bankruptcy in 1981, producing approximately 5,000-6,000 units across three major revisions.
Mk I (1972-1975) featured white or cream-colored panels, the two-pole filter, and rotary pitch bend. Some late Mk I units added CV/gate interfaces. Mk II (1975-1978) adopted black and gold livery, added standard CV/gate, and transitioned through various filter designs. Mk III (1978-1981) introduced orange-on-black styling, the 4075 filter, unbalanced XLR output, and Proportional Pitch Control (PPC)—three pressure-sensitive buttons replacing the rotary pitch bend.
After ARP's demise, Korg acquired the rights and reissued the Odyssey in 2015 in collaboration with David Friend. This reissue offered all three original filter types switchable, MIDI connectivity, USB, and both full-size (FS) and compact (module) formats. Behringer released their interpretation in 2019 with additional features including digital effects and sequencing.
Notable Users
The Odyssey appeared on countless recordings across diverse genres. Its aggressive, cutting tone made it popular for lead lines and basses in electronic, rock, and funk music. Artists including ABBA, The Beach Boys, Chick Corea, and Depeche Mode incorporated its distinctive sound into their work.
Cultural Impact
The Odyssey helped democratize professional analog synthesis, offering capabilities previously available only in larger, more expensive instruments. Its duophonic operation influenced subsequent synthesizer design, and its filter designs became reference points for analog emulation. The 2015 Korg reissue demonstrated enduring interest in vintage analog sound three decades after production ceased, helping spark the modern analog revival.
Market & Collectibility
Original ARP Odysseys remain highly desirable, with prices varying by condition and revision. Mk I units with white panels command premiums for their rarity and distinctive character. Mk III models are most common and affordable, though still valued for their unique PPC implementation. The Korg reissues offer authentic sound at lower prices, making vintage units collector's items while preserving accessibility to the Odyssey's sonic palette.
