"A compact valve synth capable of the spectacular analog displays that make high voltage tubes essential for any serious electronic music aficionado.

In rare moments of clarity we’ve long glimpsed a brutish dream burning in the solder smoke: A compact valve synth’ capable of the specular analog displays that make high voltage tubes essential for any serious electronic music aficionado. Now the low hanging fruits of our labors are within reach & truly rotten to the core

Yes: “high voltage”—no small task for a euro module. Reason being: even the best euro format power supplies were never intended for providing “B+” (arcane engineer speak denoting High Voltage feed for vacuum tubes). Rather than compromise both the operating specs of the tube & capacity of your modular’s power supply the M Series 676 ships with it’s own. Simply plug in the included wall-wart, give the tube a few seconds to warm up & voila! Tangled in wires already? We get it, and in addition to the power jack on the face there’s another power tap hidden on the rear of the module should you want to get crafty to keep things clean. The advantage is twofold: no capacity is taken from your existing supply and the vacuum tube employed is a common model in current production (so there is no worry should it require replacement after many years of faithful service).

Like any Trogotronic worth its salt the 676 Fury’s functions are not conservative… Meaning, while there are two Main Oscillators, other parts of the circuit can command more complicated frequencies in an intuitive manner. Similarly the Main Oscillators themselves may be applied as filters serving to broaden the utility of the instrument even more so. With regard to BOTH mayhem AND stability 676 Fury’s switch settings offer different parameter reactions: Toggles “down” Oscillators & Track navigate pitch black F-5 electron turbulence; Switched UP same controls “play nice” in crimson livery with accordance to classical form.

Features

4/1/24 Roland (& RYK, Lana) System 100m + Trogotronic 676 + Zerosum Inertia PLXNA2 + Lexicon PCM 70

video upload by Cfpp0

"The RYK Modular 185 sequencer for Roland System 100m sequences two 112 oscillators, which run into the 121 VCF into the 130 VCA, with an envelope from the 140. The 130 goes to the Zerosum Inertia PLXNA2, which goes to the Mackie Onyx 1640, with some Lexicon PCM 70 (Cascade BPM). The RYK 185 also sequences a Lana 212 VCO, which runs into the FM CV on the PLXNA2. This all produces the bass line melody. Another output on the right 112 VCO goes to the input on the Trogotronic 676, which creates the dissonant drone that is slowly faded in on the Mackie (with a lot more PCM 70)."

Trogotronic 277M Stereo Tube VCA Eurorack Module

"Trogotronic M-Series 277 offers a high-gain Vacuum Tube Stereo VCA without sonic compromise. Tube Harmonics, Bass-Heavy Compression & Stereo Imaging are applied with 2 Discrete High-Voltage VCA Circuits.

Yes: “high voltage”—no small task for a euro module. Reason being: even the best euro format power supplies were never intended for providing “B+” (engineer speak denoting High Voltage feed for vacuum tubes). Rather than compromise both the operating specs of the tubes & capacity of your modular’s power supply the M Series 277 includes a wall-wart to deliver both High Current & High Voltage to the valves without taxing your rack’s supply. Low voltage / low current circuits patch via included ribbon cable & use only a modest amount of power (see specs below for details). 277 provides front & rear jacks for the included supply to facilitate access from outside OR inside your rack (cuts down on added wires getting tangled with patch-cords on the frontside).

Use at the end of a patch: Rich tube harmonics & brawny compressed low-end add warmth to your cold digital effects / signals while reinforcing plastic sounding low voltage analog sound.

Use to portray mono signals as vast stereo audio panoramas: The 2 discrete channels run in parallel add depth to mono signals (patched to both inputs) with organic stereo imaging built into the circuit. The same mono signal can be dynamically panned via CV Amplitude inputs.

Use as a stereo overdrive effect: The Drive CV is discrete (1 for each channel independent of the other) so creation of dynamically panning stereo overdrive effects via CV Drive is a cinch.

Use as external input stereo preamplifier: Gain afforded by the 277 is more than adequate to make even the tiny signal of a guitar or microphone patched straight to the input scream. As a modular synth is more than 1000 times louder you may well wonder what happens when such signal is fed through the 277 with controls all set to “eleven”: brutal distortion!

Features

2 Tube VCAs
2 CV Amplitude Inputs with Attenuator Knobs (1 per channel)
2 CV Drive Inputs with Attenuator Knobs (1 per channel)
Ample gain for use as a Stereo External Input Preamplifier
Zero to +5 volt CV-Range compatible w/most LFOs, Envelopes etc.
Warm Tube-Harmonics
Compression with Low-End Enhancement
Compelling Stereo Imaging
CV Controllable Panning
Pannable Stereo High-Gain Tube-Overdrive Effect
Warms cold digital effects & low-voltage solid-state signals
Included High-Current Power Supply = low impact on your rack’s “built-in” supply
4 CV Lamps: 2 Blue (Amplitude A & B) / 2 Red (Drive A & B)
2 Slovakian Max. Gain, Twin-Triode Vacuum Tube run at high-voltage"

Trogotronic 676 & Makenoize Rene - range of sounds.

Published on Nov 22, 2012 by DJjondent
"This is a reply to a number of requests regarding the sound of the Trog 676 valve oscillator.
Just tweaking its VCO to demo its audio range.

The Rene touch sequencer outputs two CVs (x & y axis).

Named after the French philosopher & mathematician René Descartes.
http://www.youtube.com/watch?v=BHihkRwisbE

The lovely thing about it (apart from the touch aspect) is that it doesn't run in a straight line.
It uses a Cartesian coordinate system:
http://www.australiancurriculum.edu.au/Glossary?a=M&t=Cartesian+coordinate+system
I'm using just 2 clocks here,but it can take 4 clocks & 2 CVs.

Great for composing complex musical patterns."

"If not for Metasonix, I would never have bought any eurorack. Metasonix is a legendary company, producing legendary products. And, of them, this R-56 is amongst the rarest.

The R-56 has been out of production for years, and will never be re-released. We’ve all asked. The parts are simply not available. So these are rare, and expensive.

It’s a WTF sort of module. A spring reverb you can voltage control. It has a unique sound, even within the Metasonix realm. Customers complained about wanting MORE gain, said the great Tube Pioneer, so this module has it. That insane gain, plus the ability to feedback an electromechanical spring reverb, make it a module that requires finesse (and maybe an attenuator, or matrix mixer). If you are impatient, or unfamiliar with Metasonix‘s quirks, please pass on this listing. It’s odd. Really weird. Also it requires a lot of power for the cold inrush, power on, tube warm up, so you’ll need a nice beefy power supply like an RKP or Trogotronic.

The video in this listing’s photo section features the sound of this exact module.

More likely, you’ve been longing for this, but the blood sport that is Metasonix’s secondary market has kept you from your dark distorted springy dreams. Realize them now. Live them. Buy."

MODEL 673 WAVEWRAITH

video upload by trogotronic

"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."

"Little brother of the double-wide 277 the 177 does in mono what big brother does in stereo. The unique design of the M-series 177 delivers not one but two stages of high-gain (& high voltage) vacuum tube signal path without sonic compromise. Harmonics & Bass-Heavy Compression unique to valve topology are delivered with an economy of “hp” real estate (7.5hp!), meager power supply requirements & cost while maintaining Euro Format CV compatibility.

Martian Devil Chickens - Trogotronic 679m Demo - Mark Steiner

Published on Jul 19, 2014 Mark Steiner

"Nothing is input (CV or sound) into the 679 in this demo.

The 679 sound and CV is routed to an Animodule DD Dual VCA. This causes the 679's wave form to control the panning of it's own sound and really draws a nice sound image across the stereo spectrum.

The reverb is Valhalla Shimmer.

At about 13 minutes in, the sound is also routed through a Doepfer A-125 Voltage Controlled Phase Shifter, whose phase is also CV'd at various levels by the same 679 output.

All live adjustments on the module knobs.

This is a rediculously long demo, and it may be good to just click through here and there to get an idea of some possibilities. I included my whole exploration take here as it's the kind of thing I'd like to hear when considering a module.

Love the 679.

You definitely discover sounds more than design them with this creature.

I love the nice vactrol and tube sound with this module."

"Includes ribbon cable and mounting screws. Nice condition showing just normal wear and typical rack rash. Works perfect. If you are into noisy experimental stuff, this is your module. You can even run audio into it. This thing is really bizarre, hard to understand / control, and full of surprises and happy accidents. Very cool. Black panel version. Getting really hard to find these now."
