DivKid Unleashes the Deuxd: Stereo Filter Mayhem for Modular Maniacs

DivKid’s back at it, this time diving headfirst into the Deuxd from Mehr Music Machines—a Eurorack stereo filter that’s as subtle as a brick through a window when you want it, and as clean as a monk’s laundry when you don’t. We’re talking cross modulation at audio rates, stereo filth, and enough patching tricks to keep even the most jaded modular heads awake at night. If you’re after a filter that can morph from buttery smooth to bonkers chaos with a flick of a switch, this one’s got your name on it. Don’t let the polite panel design fool you—this is a proper rave bunker tool, and DivKid’s demo is all about pushing it to the edge.

Stereo Street Weapon: Deuxd’s Core

Right out the gate, DivKid introduces the Deuxd as a stereo filter module that’s all about flexibility and cross modulation. It’s not just another pretty face in the rack—this thing’s got dual filters, each with their own low pass/high pass switch, resonance, FM inputs, and a global cutoff that can sync or oppose the two sides. The summed output even lets you pick between filthy diode clipping or dirtier distortion, so you can dial in as much character as your mix can handle.

What really sets Deuxd apart is its focus on stereo audio rate modulation and experimentation. DivKid points out that this might be the first stereo filter with cross modulation to hit the scene, and it’s clear the module wants you to push it hard. The layout is simple, but the sonic results are anything but—think clean sweeps one minute, then gurgling, overtone-laden chaos the next. If you’re after a filter that can keep up with your most unhinged patch ideas, this one’s got the muscle.

The circuit design for the resonance is really quite hot. It starts to oscillate below half of that pot turn, but the tone and the effect…

Cross Modulation: Pre, Post, and Pure Mayhem

Deuxd isn’t just about basic filtering—it’s a cross modulation playground. DivKid breaks down how the module offers both pre and post filter cross modulation, with clever internal normalisations that let you route audio and modulation signals across the two filters without a spaghetti mess of patch cables. Pre-filter FM lets you get those classic audio-rate modulations, while post-filter XMOD takes things into wild, interactive territory.

The beauty is in the details: you can blend subtle harmonic movement or go full-on rubbery, buttery, overtone insanity. The summed output’s dirty/filthy switch adds another layer of character, making Deuxd a proper tool for mangling everything from basic oscillators to complex drum mixes. It’s the kind of module that rewards experimentation—just when you think you’ve tamed it, another twist of the knob sends your patch spiralling into new territory.


From Bass Monsters to Stereo Soundscapes

These are really kind of complex, rubbery, buttery, audiorate, overtones. Without the need for any complex patching.

DivKid wastes no time showing how Deuxd can be the backbone of monster bass patches. Pair up a sub square and a saw, run them through the filthy sum stage, and you’ve got a backend that kicks like a drunken horse. The module tracks pitch, animates with envelopes, and lets you crossfade harmonically between voices for smooth performance transitions.

But it’s not all about brute force. Deuxd shines when stereoising mono sources, turning a humble single input into a wide, animated stereo field. With independent filter modes on each side and clever modulation, you can pan, tilt, and dance your sounds across the spectrum. Whether you’re after a thick bassline or intricate spectral blends, this filter’s got the range to cover both ends of the sonic street.

Performance Patches: Clean Meets Chaos

Where Deuxd really earns its keep is in live performance patches. DivKid runs drum buses through it, flipping between clean sweeps and all-out distortion with a twist. The summed output’s dirty mixing stage adds a thick, processed mono centre to your stereo beat, and the cross mod controls let you inject as much instability as you fancy.

Things get even more interesting when you start patching feedback loops, variable bandwidth filtering, and stacking modulation sources. The module’s internal routing means you can go from notchy phaser-like effects to utter, gurgling filth without losing musicality. It’s a filter that begs to be played, not just set-and-forget—perfect for anyone who likes their modular performances unpredictable and a bit dangerous.

I like playing with the depth of modulation to both sides and the manual sweep into this modulated really characterful state and then back…

Deuxd in Action: Real-Time Sonic Alchemy

This is the kind of thing I'd love to talk about and to nerd out over synthesis techniques.

The last chunk of the video is a real treat for patch nerds. DivKid dives deep into the pre and post cross modulation options, showing how you can create everything from clean sine-based FM to slurpy, moist filtering that sounds like a toaster-fight in a rainstorm. There’s a masterclass in using dummy cables to clean up your modulation, and a reminder that sometimes the best results come from just pulling cables and seeing what happens.

If you want to see Deuxd pushed to its limits—independent dual mono filtering, voltage controlled resonance tricks, FM drones, and feedback patches that spiral into hours-long wormholes—this is where it happens. Some of the nuances and sheer filth are best experienced with your own ears, so don’t just read about it: watch DivKid’s demo and prepare to lose a few hours in the patch bunker.
