Voltage Labs Unleash the Polivoks-8: Soviet Fury Goes Polyphonic

Voltage Labs have rolled into Superbooth 2026 with the Elta Music Polivoks-8, a synth that takes the infamous Soviet Polyvox and cranks it up to eight voices of analog chaos. Forget nostalgia—this thing is a modern street weapon, packing digital brains with pure analog muscle. Dual oscillators, classic filters, joystick madness and enough play modes to keep your rave bunker shaking. If you want a taste of vintage grit without the vintage headaches, Voltage Labs’ slick demo is the place to start. Just don’t expect polite sounds or polite commentary—this beast is here to rumble.

Soviet Legacy Reloaded

Voltage Labs kick things off by introducing the Polivoks-8, a synth that doesn’t just nod to the Soviet era—it drags the Polyvox kicking and screaming into the present. We’re talking eight voices of pure analog, all based on the original Formanta Polyvox circuits from the 80s. It’s not just a reissue; it’s a full-on resurrection with modern muscle.

The Polivoks-8 is no museum piece. Under the hood, you get digital control for patch saving and modulation, but the sound path stays stubbornly analog. This is the kind of hybrid that actually makes sense—old-school filth with new-school brains. If you ever wanted to run a rave bunker with Soviet hardware, here’s your ticket.

It's like eight analog voices, which are reproduced at the original circuit from the Soviet Formanta Polyvox synthesizer out from the 80s.

Oscillators, Filters, and Modulation Mayhem

Each voice consists of the two oscillators, like a classic Polyvox, but it also has the analog ring modulation between the oscillators.

Each voice on the Polivoks-8 is loaded with two oscillators, just like the original, but there’s more: analog ring mod, FM between oscillators, and a sub-oscillator that can drop one or two octaves for extra rumble. You’re not just getting the basics—you’re getting a full arsenal for dirty, aggressive sound design.

Filter fans, rejoice. There are two: the classic Polyvox filter (with the same Soviet schematics) and a ladder filter, each with their own envelope. Add in a third envelope for the VCA, and you’ve got modulation options that’ll keep you busy until the next ice age. This isn’t just a polite polysynth—it’s a toaster-fight in a box.

Joystick Antics and Play Mode Madness

MIDI polyphonic extension? Check. USB-C and easy firmware updates? Of course. But the real fun starts with the joystick—a two-axis mod monster that can be recorded and replayed through the modulation matrix. It’s like strapping a rocket to your LFO.

Play modes are where things get wild: classic poly-8, para-2, mono, and three flavours of unison. The unison modes let you stack and detune voices for a sound that’s fatter than a warehouse PA. You can even split or layer sounds, so if you want to shake the walls or just annoy your neighbours, the Polivoks-8 has you covered.

We have a joystick, which could be used for real-time modulation, like two axes of it, X and Y, and we can record the joystick and use your…

Authentic Soviet Guts, Modern Wrapping

Voltage Labs made sure the Polivoks-8 isn’t just a tribute—it’s got the original Soviet micro-schematics inside, now built with modern Latvian production. That means you get the gnarly, unpredictable character of the OG Polyvox, but with reliability and features that don’t suck. It’s the best of both worlds for anyone who wants real analog bite without the vintage drama.


Sound Demos: Grit, Growl and Glory

The video doesn’t just talk specs—it throws you straight into the sonic deep end. From classic polyphonic pads to unison basses that could flatten a small car, the Polivoks-8 shows off its range. The joystick modulation and play modes aren’t just for show; they push the synth into wild, unpredictable territory.

You’ll hear everything from layered textures to fat, detuned leads, all dripping with that unmistakable Polivoks attitude. The analog ring mod and FM add extra dirt, while the filters snarl and scream in true Soviet fashion. If you want polite, look elsewhere—this thing is all about attitude.

Honestly, words don’t do it justice. The real grit, growl and chaos are best experienced in the video itself. If you want to hear what a modern Soviet beast sounds like, you need to watch—and maybe brace yourself.
