01Overview

HX-ODDY recreates the sound of the ARP Odyssey, a 1972 duophonic analog synth known for its rich character and its ability to mimic natural instruments. UVI built the plugin around the white-face Mk1 model, which served as the reference for development. The instrument covers Windows and macOS and is available in VST3, VST2, AU, AAX and Standalone formats, making it usable in most major digital audio workstations.

Sound Engine and Analog Character

HX-ODDY uses a Hybrid-X engine that combines deep hardware sampling, two hardware-based wavetable oscillators and physically modeled filters. UVI says the goal is to capture the essence of the white-face ARP Odyssey Mk1 using top-tier sampling and DSP techniques.

The original synth is described as duophonic, with oscillator cross-modulation and filters that could produce a broad sonic range. HX-ODDY is designed to reproduce that range, from bass and leads to pads and arpeggios.

Patch Design, Presets and Arpeggiator

For sound design, the plugin offers a three-layer architecture, ADSR envelopes, modulation routing, analog-modeled filters and macro and studio effects. These tools let you build custom patches from the ground up.

The included library holds 280 presets built from more than 13,000 samples and 181 layers. An arpeggiator/phraser with built-in pattern presets supports sequencing of dynamic lines.
