Nu-Trix The Synth Guy Unleashes Polyrex: Juno Vibes, No Fuss

Polyrex wears its Juno inspiration on its sleeve and doesn’t pretend otherwise. Nu-Trix The Synth Guy wastes zero time—straight into the interface, no history lectures, just a quick nod to Safari Audio’s pedal roots before diving headfirst into the synth. The first impression? It’s all about simplicity. This isn’t one of those labyrinthine soft synths that require a PhD to get a decent sound—everything’s upfront, clearly labelled, and ready to tweak.

You get instant access to the core building blocks: square, saw, sub, and noise, right where you need them. If you’re after a deep menu dive or endless modulation madness, you’re in the wrong rave bunker. But if you want to slam out 80s tones in seconds, Polyrex is basically a sonic toaster—drop your MIDI in, and out pops hot synth bread. Nu-Trix’s style suits this perfectly: quick, pragmatic, and focused on what actually makes noise.

The oscillators are everything you’d expect from a classic Juno tribute, but with enough flexibility to keep things spicy. You can blend saw, square, and sub, plus throw in some noise for those dirtier textures. Pulse width modulation is strictly for the square wave—just like it should be—driven by a single LFO that handles multiple duties. There’s no detune between the main waves (they’re locked), so don’t expect instant chord stacks, but you do get a fat, unified sound.

Envelope controls are stripped back but effective. There’s only one envelope, but you can switch between traditional amp shaping and gate mode for snappy, on-off action. Want to get a filter envelope moving while the amp stays loud? Easy. It’s classic workflow, and Nu-Trix points out the same quirks you’ll find on vintage boxes. This isn’t a synth for menu diving—just twist, play, and let the sound do the talking.

If you like your synths dry, Polyrex still sounds solid, but once you flick on the built-in effects, things get wide and wild in a hurry. Chorus comes in two flavours—stackable for that classic, lush stereo sweep. Nu-Trix is clearly a fan of the second chorus mode, which gets properly wide and gooey, perfect for those big nostalgic pads or aggressive basses.

Delay and reverb are on tap, too, straightforward and effective. You can sync delay to tempo or run it free, and the reverb adds just enough space without drowning things. There’s nothing here to trip over—just instant atmosphere at the twist of a knob. If you want to deep-dive every parameter, you’ll have to watch the video; words don’t do justice to the fatness of those chorus-drenched sounds.

This is where Polyrex flexes its muscles—Nu-Trix runs through a blitz of sound demos, and the bass patches are absolute monsters. The combination of sub, unison, and fat chorus delivers the kind of low-end that would get you evicted from most London flats. The poly/mono modes mean you can go from lush six-voice chords to snarling mono leads with a click.

There’s plenty of variety in the presets, too, from classic Juno sweeps to noisy, modern-sounding textures. The video’s the only place you’ll hear the full punch—written words just can’t capture the weight of those wide, chorusy basses. If you’re hunting for sounds that slap straight out the box, Polyrex is a proper street weapon.
