VOID Modular Gravitational Waves Demo

Sean Pendleton

"A demo of the Gravitational Waves dual VCO -

VCO 1 and 2 saws and VCO 1s sub are mixed Timo’s SSM2044 and them direct to output. I think I wrongly called that a Fonitronik Module, but it’s actually based on Foniks implementation.

Envelopes are provided by the VOID Modular Dual ADSR"

Void Modular Graviton VCO Demo

Published on Aug 15, 2019 Sean Pendleton

"VOID Modular Graviton VCO Demo by Pressurewave

A swiss army knife of a VCO in 8hp. Triangle, sine, saw, pulse, /2 suboctave square, /4 suboctave square, white noise, pink noise. The noise is normalized to the FM attenuverter, so you can do anything from 'a little dirty' to 'tuned noise'. It's 3340 based, so it's very stable, but enough extras to give it some personality."

Sirius’ Veil Stereo VCF Demo

Published on Jul 5, 2019 Sean Pendleton

New eurorack module & synth kitten.

"Sirius' Veil is a stereo state variable filter with interesting features.

First 3 minutes - Gravitational Waves as input
Last two minutes - Drums as input

The right audio input is normalized to the left audio input for mono input signals. There is a master cutoff control and master CV control in the middle, and a switch to invert the master CV to the left channel for panning type effects. Each channel has VC resonance, cutoff offset, offset CV, and a VCA. The right VCA is normalized to the left VCA.

You are able to choose the filter state (LP, BP, HP, NP) with a push button, or a it can be changed via a gate or trigger into the "state" input. A three position switch on each side selects the number of steps available (2, 3 or 4).

Pairs great with a Gravitational Waves!

Available in my Etsy shop.

A really boring demo of the Brutalist VCF

Published on Nov 23, 2018 Sean Pendleton

"Demo of the new version of my 'Brutalist' VCF. The Brutalist is a Polivoks-ish style filter with resonance boost, overdrive, and a lowpass/bandpass mix output. It’s available from my Etsy store https://etsy.me/2Ah0vhb [VOID Modular] I will also have DIY PCBs as soon as I write a build guide."

VOID ADSR

My ADSR Published on Jul 21, 2018 Sean Pendleton

"More test driving of the ADSR I made. The outputs on the left are normal, attenuverted, and a mix of the two ADSRs attenuverted outputs. There is a switch to turn an incoming gate signal into a trigger if you want your envelope extra snappy. That's also my mixer with mutes next to it and on the top right my 'Brutalist' filter."

Dinky's Taiko

I just got a Dinky's Taiko. Published on Jan 2, 2017 Sean Pendleton

"Messing With Dinky's taiko and shit for about 9 minutes. BSP is the master clock, all sequences are from the Klee and Turing machine. Yeah, I had my phone turned stupid. I know. I yell at people for this, but I recorded the whole thing this was and didn't want to rerecord. DANK DINKY'S FARTS."

New Eurorack Manufacturer Tsyklon Labs

CHAOS DIVIDER HV Eurorack Clock Modulator Module

"A clock signal. A serial chain of pulses. Some wide, some narrow. Some pulses are taller than others. Others, not so much. A clock may not the most exciting signal that gets passed around a modular synth, but it is certainly a useful signal. Take that clock pulse and pass it back out. But maybe instead of high fidelity, you drop every other pulse. Or maybe every third, or fifth, or eighth. By dividing your clock train, you can run an entire “drum set” of modules with one input and many outputs. But what happens when you add unpredictability, chaos if you will, to a normally pedestrian module? You get a CV controllable, multi-divisor, revolutionary clock modulator we call the CHAOS DIVIDER HV:

It is easy to be distracted by the glow of the Mode indicating Nixie tube (HV means HIGH VOLTAGE), this is a hard module to miss. But look past the neon beauty, and you will see a module with brains too. Front panel or CV selectable divisor mode, 9 outputs (inverted or normal outputs selectable with front panel toggle switch), division reset via push-button or trigger/gate input, and front panel and CV controls for Intensity and Interval chaos variables. Oh, and a clock signal.

The Mode control lets you select the divisor sequence from the list displayed to the left of the Nixie tube. In CHAOS mode, the divisors change at random according to the Intensity and Interval chaos variable selectors. The Intensity variable changes the range of the randomly selected divisor and the Interval variable changes how often divisors are recalculated. In non-CHAOS mode, the Interval variable introduces slip (or delay) to the outputs. This causes the outputs to be delayed from the incoming clock signal. Similarly, in non-CHAOS mode, the Intensity variable selects whether the slip applied to all outputs is the same (low Intensity) or varies across the outputs (high Intensity).

A few technical details: CV input allowable range is 0-10VDC. Anything over 10VDC is limited to 10VDC. The output pulses can be individually configured from 5-10VDC with a twist of a trimpot. Front panel controls behave as an attenuator for CV inputs.

Add our expander module, the CHAOS DIVIDER SPUTNIK (by the way, Sputnik means “Companion” in Russian), and unleash all the features that make the CHAOS DIVIDER a clock modulator for the people, Comrade!

Technical Specifications:
– 129.4mm (5.095″) Front Panel Height (3U Eurorack format)
– 12HP Module Width
– 51mm Module Depth
– Power Consumption: +12V = 165mA, -12V = 0mA, +5V = 0mA

Front panel graphics were designed by the inimitable Hannes Pasqualini @ Papernoise

Assembled modules retail for $400 USD, and Front Panel/(3)PCB/Rare Parts sets sell for $85 USD."

CHAOS DIVIDER SPUTNIK Eurorack Clock Modulator Expander Module

"In Russian, SPUTNIK means “Companion” – and that is exactly what the CHAOS DIVIDER SPUTNIK module is. A companion, or more accurately, an expander module for the CHAOS DIVIDER.

Want to change your CHAOS DIVIDER clock divider into a frequency divider? Flip the “Division” switch, Comrade! Would you rather have twice as many clock outputs and go half as deep with the divisions? The “Split” switch was added just for you. Do you need Gate outputs instead of Trigger outputs? There is a switch for that too. There is also a front panel control and a CV input for dialing in Gate Length.

Can you keep a secret, Compai? Each CHAOS DIVIDER comes with a 4HP blue acrylic place holder panel. Our shpiony report that this place holder is nearly identical to the CHAOS DIVIDER SPUTNIK panel. So you can use the place holder to save 4HP in your rack for the CHAOS DIVIDER SPUTNIK, or, if you are an enterprising Udarnik, you can use the place holder panel to make your own CHAOS DIVIDER SPUTNIK! #diyforthepeople

Technical Specifications:
– 129.4mm (5.095″) Front Panel Height (3U Eurorack format)

CORE Eurorack Passive DI Module

"Do you need to connect your Eurorack synth to a balanced audio Live or Recording rig? Find the solution with our Transformer-Based Passive DI module called CORE.

CORE is a passive transformer coupled direct injection unit for connecting a Eurorack synth to the microphone/line levels in mixers and recording equipment as well as passing the Input signal directly to the Thru connection. CORE features a Sowter 8044 12:1 DI Transformer with a Mumetal core and an XLR connector from Neutrik. Signal Attenuator and Ground Lift controls (both pre-transformer) help you trim the signal as needed. While the audio portion of this module is passive, it can be connected to a Eurorack power supply to provide LED indication of Ground Lift mode – BLUE halo around the transformer for ground connected and a RED halo for ground lift.

While the audio circuitry of CORE is passive, if you connect CORE to your rack’s power supply for the backlighting/ground lift indication, expect that it will draw 4mA or less.

Technical Specifications:
– 129.4mm (5.095″) Front Panel Height (3U Eurorack format)
– 8HP Module Width
– 35mm Module Depth
– Passive Audio Path
– Power Consumption: +12V = 0mA, -12V = 4mA, +5V = 0mA

Assembled modules retail for $220 USD, full kits are priced at $149 USD, and “Supply your own Transformer” kits sell for $70 USD."

BELKA and STRELKA Eurorack Germanium Fuzz Module

"Start with CV control over two stages of gain powered by Russian Germanium transistors. Dose the circuit with 4 different types of diode clipping. Top it off with a power starve pushbutton, a feedback circuit, and a squirrelly transistor derezzing circuit. Take all of these components, give them three orbits around a dying star, and you have our fuzz singularity, the BELKA and STRELKA.

Named after the first two Stardogs to fly into space and return safely to earth, BELKA and STRELKA is a Germanium Fuzz module with selectable clipping modes and CV control over Gain Stages 1 and 2. BELKA and STRELKA features NOS Russian Germanium transistors in the gain stages and NOS Russian Germanium and Silicon diodes for clipping. The clipping section also features hard and soft LED clipping as well as a purposefully mis-biased transistor that sounds so squirrelly that we had no choice but to name it after the Stardog Belka (squirrel in Russian). The BELKA and STRELKA fuzz module also has an adjustable feedback function that blends a portion of the output straight back to the input of the module. Lastly, the Starve pushbutton, when pressed, disconnects the first gain stage from the +12VDC supply and lets it fizzle out as the charge on the starve capacitor discharges.

Technical Specifications:
– 129.4mm (5.095″) Front Panel Height (3U Eurorack format)
– 8HP Module Width
– TBD Module Depth
– Power Consumption: +12V = TBD, -12V = TBD, +5V = 0mA

Front panel graphics were designed by the inimitable Hannes Pasqualini @ Papernoise

After building our first set of prototypes and reviewing them at our test facilities, we have made the difficult decision to delay the release of this module until later this year. It is so very close, yet we know we can make it much better."

"Love Rings and Braids, need to build more of both. I can't wait to build Clouds and Elements. Klee is controlling the Rings, Turing machine on the Braids. Drums are a Corny Rhythm controlling a Barton Analog Drum, Decaying noise, and Synthrotek DSM. Radio Music and Wogglebug are making noise in the background. Kept things simple."

Modular Drums

Published on Oct 7, 2015 Sean Pendleton

"Playing with some simple modular drum patches.

Bass drum is the Mankato filter self oscillating and swept by an AR, then going into a CGS tube VCA.

Snare is the the noise form the TH super controller, Swept by an AR, then into a wasp filter clone, and into the CGS tube VCA

Hihats are 2 vcos into a ring modulator and then into a VCA.

Other drumish sound is a Wogglebug Ringmod out going into a vca. Always remember to screw your Wogglebug panel in before using.

Drone at the start is the Orgone Accumulator

Bass is an XR VCO triangle going into a MFOS Wave Freaker + a second XRVCO Saw, and then into the MA Discrete SVVCF

Leadish thing is the TTSH"
