The Unperson Unleashes the Korg Poly-800: Cheap, Cheeky, and Still a Street Weapon

Back in 1983, Korg dropped the Poly-800—a synth that didn’t just undercut the competition, it mugged them in a dark alley and ran off with the loot. Most polysynths of the era were heavy, expensive, and about as portable as a fridge. The Poly-800? Light, affordable, and ready to crash your bedroom studio.

What made it a game changer wasn’t just the price. Two DCOs, an analogue filter, and up to eight voices of polyphony meant you could actually play chords without your wallet crying. The Unperson wastes no time pointing out how these units still pop up on eBay for sensible money, making them a go-to for anyone who wants classic sounds without the vintage tax.

Let’s get one thing straight: the Poly-800 is paraphonic, not truly polyphonic. All voices share the same filter and VCA, so don’t expect Prophet-style luxury. But that shared filter trickery gives it a unique bite—especially when you’re stacking chords and triggering envelopes in weird ways.

Programming is a keypad adventure, with numbers for everything and presets that start at 11. Want to tweak resonance or envelope release? You’ll be punching in parameter codes like you’re hacking a mainframe. The Unperson walks us through the quirks, showing off the six-stage envelopes and the infamous chord memory—eight-note stacks if you’re brave enough to go single DCO. There’s even a sequencer, but it’s got more switches than a dodgy toaster. It’s all part of the Poly-800’s charm.

Here’s where the Poly-800 earns its street cred. The Unperson builds a full track using nothing but this synth, recording each part separately and stacking them into a split-screen performance. No DAW, no laptop—just pure hardware hustle.

The layering shows off the Poly-800’s versatility. Bass, pads, leads—all from the same box, each with its own character. The jam isn’t just a technical demo; it’s a proper tune, with groove and grit. The split-screen setup lets you see every part in action, making it clear how much you can squeeze out of a single synth if you know your way around its quirks.

If you want to see how a so-called “budget” synth can fill a room, this is the bit you don’t want to miss. The video captures the energy and rawness that words just can’t do justice.
