The Unperson Chains Chaos: RYK Side FX Gets the Sparky Treatment
Four-Headed FX Monster
RYK Modular’s Side FX isn’t your average effects toy. This thing runs up to four independent effects at once, letting you stack, split, and reroute like a mad scientist at 3 a.m. Whether you’re after pitch-shifting chaos, tape simulation grit, or reverb soup, the module’s arsenal is broad enough to keep even the most jaded Eurorack heads grinning.
The Unperson doesn’t waste time on pleasantries—straight into building an effects chain from scratch, with a menu that reads like a greatest-hits for modular noise freaks. Pitch shifter into tape sim into dual delay into plate reverb? Sure. Each effect is its own little universe, and you can only pick one from each category, so get clever with your combos.

Twist, Mod, Recall—Without Losing Your Mind

"The muting of effects is actually called send mutes and it's a really cool feature because we can trigger the mutes with the external inputs."

Interface-wise, Side FX is refreshingly direct—no menu-diving nightmares here. Modulation comes in hot, with four external CV ins and a four-pack of internal mod sources (LFOs, random, envelope follower). Routing modulation to pretty much anything is a button-hold away, and muting effects isn’t just an on/off kill—it’s got smooth tails for slick transitions.
Saving your madcap patch? Easy. The preset system lets you burn your favourite mayhem into memory and recall it mid-set. Effects order and routing are next-level too, with seven different algorithms letting you go serial, parallel, or full-on dual-mono for processing separate audio streams. It’s all there, minus the brain-melt.
Patch Hacking: Getting Weird in Real Time
The Unperson gets down to business, stacking effects and using send mutes to trigger chaos with external sequencers. The send mute function doesn’t just cut—effects trail off, making it perfect for evolving jams and sneaky transitions. It’s like tossing effects in and out of the mix without killing the groove.
Sequencing the effects themselves? Absolutely. Using gear like the OxyOne, you can automate send mutes and create intricate, evolving effects chains that sound more like a live set than a static patch. Bitcrush, pitch shift, delays—everything’s game, and the module never sounds flat or polite. If you want to hear the real madness, you’ll need to catch the video and hear it squirm.

"This is what I really love about the send mutes. You can get these just sort of simmering background effects."

Presets: From Ambient Soup to Rave Bunker
Factory presets aren’t just demo-fodder—they’re legit starting points for mangling sound. The Unperson rips through a pile of them: lush reverbs, crunchy delays, spacey resonators. Whether you’re after shimmering ambience or straight-up audio destruction, there’s a preset to kick off your next toaster-fight. And yeah, you’ll want to hear these in action—text alone won’t melt your face like the real deal.
Real-World Rigs: Performance Tricks You Need to See

"And the fact that this has sort of four categories of effects that we can layer on top of each other is a major bonus in my opinion."

The Unperson doesn’t just twiddle knobs—he’s wiring up drones, sequencing effects, and using Side FX as a proper performance weapon. Chords are frozen, delays tap-dance across the stereo field, and the granulator locks in textures that’ll haunt your dreams. If you’re the sort who wants to actually perform with your rack, rather than just stare at blinking lights, this module’s performance features are begging to be abused. But honestly, this is one of those cases where you need to watch the video to get the full dose of inspiration.
