UVI is a Paris-based developer of software instruments, effects, and sample libraries for music producers, composers, and sound designers. The company grew out of Univers Sons, a French audio retailer and developer founded in 1986, and has built its reputation around deep-sampled virtual instruments and hybrid synthesis tools used in records, film scores, and video game soundtracks.

UVI's flagship product is Falcon, a hybrid instrument and sound design environment combining subtractive, FM, wavetable, granular, additive, and physical modeling synthesis alongside a sampling engine, modular effects, scripts, and MIDI processing. The company also develops the free UVI Workstation player, the SonicPass subscription service, and the iOS apps Ravenscroft 275 (a sampled grand piano) and BeatHawk (a mobile production studio).

Beyond Falcon, UVI's catalog spans orchestral and world instrument libraries (World Suite, Orchestral Suite), vintage synth recreations (PX Apollo, Vintage Legends collections), drum and percussion libraries, and a range of effects plugins including Sparkverb, Thorus, Relayer, and Rotary. Its soundware is often built around recordings of rare or historically significant hardware, which has made it a go-to source for producers looking for niche timbres and recreations of classic gear.

UVI has 78 products cataloged on Equipboard, including Virtual Instrument, Synth Plugins, and Instrument Bundles. Their gear is featured by 13 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Deadmau5, Vernon Reid, and Ferry Corsten. UVI's catalog spans the full price spectrum — from entry-level options to high-end flagships.
