Prepare for a sonic assault as optoproductions dives into the murky world of distorted rhythms. With a setup that would make any sound engineer’s hair stand on end, we explore the chaotic energy of Eurorack modules. Expect gritty, raw, and unpolished sounds delivered with typical British cheek.

Patch Overview: The Chaos Begins
Kicking things off, Melvin from optoproductions introduces us to a patch the likes of which you might find at the wildest underground rave. It’s all about distortion—gritty, raw, and real. The heart of this monstrosity is the Yarns module, tirelessly working away like a four-track MIDI sequencer. This module is the puppeteer behind the curtain, pulling all the rhythmic strings and setting the stage for some delicious chaos. Everything’s wired up to get those distorted rhythms pounding your eardrums with relentless fervour. Like a pub brawl in a sound chip, everything’s set for pandemonium.

"Hi folks, Melvin here from Optiproductions. I just wanted to show you a cool rhythmic patch with some distortion, filters and delays. Let's take a look."

A Proper Rhythm Rumble
The rhythmic engine kicks into gear with Yarns churning out beats more addictive than a dodgy kebab at 3 am. Trigger one is hooked up to Boba Fat, serving a kick drum synth that packs a punch. It’s paired with OCP, adding an envelope’s touch to the mix. Plaits snare mode takes command of trigger two, while trigger three dances with the hi-hat module from ST Modular. Finally, trigger four controls the hi-hat’s decay, shaping those tails like a master sculptor. It’s not just a sequence; it’s auditory art, and Melvin’s got it running like a well-oiled machine. The rhythms weave through this sonic tapestry, bringing to life an anarchic dancefloor right in your headphones.
Unleashing the Beast: Mini Drive and BBD Delay

Now we move into territory that’s grittier than a Camden basement gig—distortion. The Mini Drive from Music Thing Modular is the unsung hero, adding dirt and drama. It’s simple to assemble and doesn’t break the bank, perfect for those wanting to unleash sonic madness without financial regrets. The Erica BBD Delay takes centre stage, adding its own spicy echo to the mix. Treated to a fully wet setting, the delay’s feedback begins to swirl until it hums like a behemoth ready to roar. It’s a feedback loop of chaos, riding close to the edge like a hoarse shout in an overcrowded club.
Filters and More Filters
What’s funkier than filtering sound through a pair of mismatched socks? How about throwing a low-pass and a high-pass filter into the same patch and letting them battle it out? That’s exactly what’s going down in Melvin’s setup, with sound bouncing through both filters before heading into Clouds, set to Time Stretcher Mode. It’s like a freshly pulled pint—crisp yet cloudy and totally satisfying. High-pass filters add that perfect touch of texture, similar to crafting the perfect bass-heavy dub track in a smoke-filled room. Like a skilled DJ spinning on the decks, altering the filter order brings an entirely new flavour to the output—constantly shifting, growing, and never stale.

"That's cool. Right, let's see what we can do."

The Final Twists: Emergent Sonic Chaos
As we hit the home stretch, Melvin’s patch becomes a living entity, twisting and turning with each knob move. The output cascading through DVCA, a Mutable Instruments clone that’s all about that diode-induced clipping. It’s like an amp teetering on the edge, threatening to blow but holding just enough to maintain its wonderfully gritty growl. Playing with feedback and modulation brings new layers to the chaos. This patch embodies the ‘punk spirit’—unpredictable, raw, and with a sound that’s cave-wall heavy. Each element interplays, from distortion to echo to bare rhythms, culminating in a finale that echoes the rebellion of sound.
