"Clandestine Projects go by many strange names. Projects which changed the course of history for better or worse. Manhattan, Bluebook, MK Ultra— hell—even Alan Parsons…

PROJECT ANTIDOTE (codename THE MACHINE) is the latest of such world-changing endeavors. But rather than another top-down government control-scheme funded by covert appropriation, the Military, Moonies, the Heritage Foundation or Rand Corp— PROJECT ANTIDOTE is conducted by a grassroots coalition of outsiders far from the eyes & ears of the surveillance-state.

Miles down a random dirt road a working group was assembled from the ranks of OFF!—the Hardcore Punk Supergroup—& Trogotronic’s Subhuman Resistor-Wranglers. Their mission: Design the ANTI-SYSTEM.

While silicon valley oligarchs were squandering unimaginable sums to develop “brain-enhancement implants” at zillion-dollar vivisection labs, PROJECT ANTIDOTE relentlessly refined THE MACHINE at a secret forest shanty dubbed “THE PUNK WORKS”. Success was soon realized when the pathway for organic audio-to-mental frequency-coupling was established, whereby minds are FREED rather than controlled. What’s more THE MACHINE viscerally resonates with only the MOST radical free-radicals to achieve a critical mass of illuminated population no longer subject to THE SYSTEM.

THE MACHINE includes a holistic tuning array of

11 Parameter Knobs
10 Element Light Emitting Array
All-Analog Audio Circuitry
Right vs. Left Hemispherical Design
Endless Audio-to-Brain Setting Possibilities
12v Worldwide Power Supply
Plug & Play for rapid deployment at blistering amplitudes, its immediate effects are clearly notable when the uninitiated strike a peculiar pose with each fore-finger inserted deep into the ear canal. Congratulations: IT’S WORKING!

As a redundant precaution, plans are being subliminally disseminated via unlimited multimedia release. Hidden diagrams are embedded in LP sleeves, Sportswear & Midnight Movie plots only visible in complete darkness. This way if all our efforts fail, the intrepid underground technicians among us can independently construct THE MACHINE in shanties the world over."

"673 WaveWraith is an Analog Vacuum-Tube instrument which combines the power of the Valkyrie model with the MotherMutant model's interface in a no-compromises ergonomic console. Simultaneously delicate & brute, terrifying & beautiful; time invested in Wavewraith bears dividends of ghastly key-borne transitions, lengthy Rube Goldberg cycles & endless foley ideas for the classic sci-fi horror movie of choice."

trogotronic c4 4 Channel Analog Audio Controller v5

video upload by

"20 years ago we introduced the Original 4 Channel Joystick Audio Controller. For the first 5 years most folks didn't even understand what it was. The next 5 the knockoffs came. Soon whole genres of the most disturbing music ever put to speakers was born of primitive fast-cut real-time multichannel switching.

The New v5 Features:
4x4 discreet 1/4" ins / outs
Electronic Control & 4 Discrete Analog Signal Paths
An Illuminated Full-Sized Ultra-Fast Switching Stick
Gate Signal Input
Remote Control Jack for m2 Footswitch Accessory
Modulator Button & Speed Control = Impossibly Fast Attacks
Independent Mode for each Channel = ON until OFF or OFF until ON

Ask anyone who knows: Trogotronic c4 still goes from zero to smoking hear-holes with NO BLEED like the knockoffs.

The Original remains the BEST."

Analog Audio Tube Mayhem // SpazeDrum + Infernal Noise Machine + Trogotronic 679 #TTNM


"Just a little LOUD AND DISTORTED Trogotronic Infernal Noise Machine SpazeDrum Sound of Shadows SOUND DESTRUCTION! WAAAGH!!! Well ... so ... I wanted to use the Flight of Harmony INM-E to process the analog Gotharman SpazeDrum output. But then I thought: "Why not step it up a notch?". So I added the Trogotronic 679 vacuum tube ... THING ... and sent the result through Flight of Harmony's Sound of Shadows delay too.

I love to hear from you and talk about synths and stuff, so always feel welcome to post a comment or send me an e-mail to:

This is the first post to feature one.

"Being of humble subhuman heritage there remains an aspect of joining the modular knob-mob that bugs us: the exorbitant cost of entry due before even the first bit is added to the system. Worse, in spite of the considerable costs, many of the available set-ups are a compromise: wherein there’s little or even no power capacity whatsoever or the mere offering of +5v tap is an optional luxury; wherein fragile / easily damaged enclosures or table top tinker toys are touted as options; wherein infuriating substandard mounting systems are the norm rather than the exception. After testing many of these half-assed ideas we decided that every part used in Collier Series Euro-Modular Cases should be formidably robust & user friendly—even when this meant that some parts chew into our net. The m/168 Collier Case’s ultra-powerful, worldwide-compatible 10,000 mA Power System coupled with the best rack hardware available on the planet enclosed in a nearly indestructible case is born a turnkey classic of road-defying durability & outstanding value. And now its available in the original splash-proof base model m/168 & a new version m/168s with power inlet with switch plus removable cord.

m/168 Collier Case Original Model

Rugged Splashproof Brief-Case
2 Rows of 84hp = 168hp Capacity
Twin-Pin Removable Case-Lid w/Finger Pulls
PREMIUM Swiss Rails = No Half-Assed Loose-Nut Comedies
10 Amp (10,000mA) Power System INCLUDED
Power Boards Accommodate Up To 30 Modules w/+12v, +5v & -12v
Triple Voltage Status Lamps for Power Board (+12v/+5v-12v)
Power System Works ANYWHERE ON EARTH
STANDARD Power System Supplies = Quick/Easy User Service
Plenty of Stainless Module Mounting Screws INCLUDED"

Xiu Xiu Explore Hideous Sound Design (No Talking)

video by Perfect Circuit

follow-up to this post.

"During their recent visit to our studio, Angela Seo and Jamie Stewart from Xiu Xiu showed off a number of ways to make sounds that were as hideous and disgusting as possible. After filming with all of their varied setups, we ended up with way more sounds than we could cover in just one video. While our main video provides some valuable artistic insight into their processes and choice of equipment, we wanted to share a glimpse into their sound crafting without interruptions.

In their first jam, Angela sculpts feedback loops with a collection of her favorite pedals from Earthquaker Devices, Boss, and Death by Audio, while Jamie helms the mixer and Trogotronic’s Valykrie, a modified test equipment oscillator. Next, Angela switches over to her Waldorf Streichfett, while Jamie moves to a couple pedals of his own: Death by Audio’s Echo Dream 2 and Benidub’s DS71 Dub Siren. Angela and Jamie then both perform some solo Eurorack patches, and Angela closes things out with a solo performance on her Streichfett and pedals.

Sit back, grab some headphones, and lose yourself in the depths of Angela and Jamie’s noise, chaos, and unpredictability.

Xiu Xiu Makes the Most Horrendous Synth Sounds Humanly Possible

video by Perfect Circuit

"Toting an extensive range of sonic machines, experimental group Xiu Xiu’s driving members Angela Seo and Jamie Stewart recently paid a visit to our studio to give us a lesson on intentionally crafting “the most disgusting sounds” possible. With their eclectic assortment of test equipment oscillators, a towering Eurorack modular system, effects pedals, and more, prepare your eardrums to be blessed (or barraged, depending on your inclination for harsh electronic sounds) by the pummeling frequencies contained in this video.

With some of our favorite pieces like the Make Noise DPO, Verbos Harmonic Oscillator, and the aptly named Total Sonic Annihilation from Death by Audio, Angela and Jamie show off a few setups for building up immensely destructive audio. Their valuable insight into curating feedback and noise with intention offers plenty of valuable tips and considerations for prospective explorers of the unpredictable and harsher worlds of sound design.

Trogotronic m/277 Dual Tube VCA Tutorial Videos by Learning Modular

Published on Jun 15, 2018 Learning Modular

"This set of five movies covers the Trogotronic m/277 Stereo High-Voltage Tube VCA / Overdrive / Preamp module. Even if you don't have this specific module, the series covers a lot of useful information on managing signal levels to get different sounds out of a module, stereo and faux stereo processing, and the differences between putting the VCA before or after the VCA.

The first movie is an overview & demo of the module. The remaining movies cover using it as an output overdrive processor, using it as a stereo-izer (panning etc.), how it behaves as a VCA in the “normal” position after the filter, and how that behavior changes if you place it before the VCF.

These movies are also part of my Eurorack Expansion course on"

All tubes by Weinglas

"'All Tubes' is the latest release from European noisemaker Weinglas. All tracks from this strange ride into darkness were created with the help of modular synthesizers and sound machines made with tubes. Thanks to Brian from Zerosum Inertia, Eric from Metasonix and W.T. from Trogotronic, who designed and produced these strange machines, Weinglas could turn the warmth and rawness of these old fashioned elements into never-before-heard walls of noise, sounding modern and vintage at the same time."

The following is a video for Tubemaster 2, the 10th track on the release on Vicmod Records.

Published on Nov 19, 2016 Wein Glas

"A Strange Electronic Sequence from a Buchla 200e Skylab with a Zerosum Inertia ZIMM03 Tube Module installed.
