The Unperson Unleashes the Instruo Neoni: Triangle Core Mayhem in Eurorack

The Unperson kicks things off with a confession: the Instruo Neoni has been gathering dust in the rack, but today it’s getting a proper workout. This isn’t just any oscillator—it’s a triangle core beast, meaning all its waveforms start life as triangles before being twisted into shape. The Unperson admits the technical details are a bit mysterious, but the sonic results are what matter.

With five independent outputs—square, saw, triangle, sine, and a folded sine—the Neoni is ready for modular mischief. The Unperson’s setup is classic: PAMS, Maths, a variable waveform generator, and a taste of West Coast flavour with the LXD and wavefolder. Right from the start, it’s clear this module isn’t just for vanilla bleeps; it’s built to get dirty and experimental.

Here’s where the Neoni starts flexing. True through-zero FM means you can push frequency modulation into wild territory without your pitch going off the rails. The Unperson patches in a sine wave from the variable waveform generator and flips between traditional and through-zero FM modes, instantly hearing the difference—through-zero keeps things musical, even as the modulation gets gnarly.

There’s a switch up top for toggling between FM flavours, and the Neoni holds the fundamental note like a champ when in through-zero mode. If you’ve ever had an FM patch turn into a tuning nightmare, this is the antidote. The Unperson’s verdict: this is where the Neoni really shines, especially when paired with clever modulation and sequencing tricks.

Wavefolding on the Neoni isn’t just a gimmick—it’s a full-on transformation. The Unperson demonstrates how the folded sine output morphs a basic waveform into something rich and unpredictable, especially when you start modulating the fold amount. Add a bit of delay and things get lush, evolving, and borderline chaotic.

But it doesn’t stop there. The sawtooth output has its own modulation quirks, and patching CV into the fold or FM inputs takes the sound from polite to monstrous in seconds. The Unperson’s advice: don’t be shy, throw modulation at it and see what breaks. For anyone chasing complex, evolving textures, this is the Neoni’s secret weapon.

Time to get sharp. The Unperson patches the sawtooth from the variable waveform generator into the Neoni’s sync input and runs a familiar sequence. Instantly, the sound gets a harder, more aggressive edge—think toaster-fight in a steelworks. The sync input lets you carve out tones that’ll cut through any mix, no matter how crowded.

It’s not just about brute force, though. The Unperson shows that by tweaking the sync and combining it with other modulation sources, you can find sweet spots where the Neoni balances aggression and musicality. If your patches are getting lost in the fog, hard sync on the Neoni will drag them back into the spotlight.
