Nyquist Nightmare

Audio Mangling Modulator/Demodulator

This module is a modulator/demodulator. The top four knobs interact with each other to take a signal and mangle it beyond all recognition, or if you're patient and lucky, let the signal come through mostly unchanged.

What is going on there? you ask. The input is used to frequency-modulate a VCO that can oscillate beyond anybody's hearing range. The resulting (possibly ultrasonic) signal frequency-modulates a second identical VCO. This leads to the kind of signal degradation you might expect from an AM radio transmission. Or a short wave signal fighting its way through a hurricane.

The rest of the knobs control filtering; high-pass to remove the truly ground-shaking rumbles the top for knobs can generate, and resonant low-pass to get the harsh high pitches out of the signal, and emphasize (for example) the frequency range of human speech, if you want to pass old movie dialogue through this.

Also included are a wet/dry control (while prototyping this module I would sometimes spend minutes looking for the perfect knob settings to allow a signal through just to realize the signal source had stopped playing), a CV input for the low-pass filter with an attenuator knob, and a effect volume knob.

Some fun things to try:

with zero input, try to get a modem sound!
connect a simple waveform and massage the top four knobs to fold the wave in surprising ways
David Lynch. Put David Lynch through this.
turn the resonance of the low-pass VCF up and use this as a VCO (not 1V/oct, I'm afraid
Turn both "Carrier" knobs all the way down, so the VCOs are stalled, and listen to the signal bash its way through

Compression & Dynamics Patching on Eurorack Modular Synths // Sump Pump by Robots Are Red

video upload by DivKid

"Here we have SUMP PUMP from Robots Are Red (with circuit design from Setonix Synth). It's a 6HP stereo Eurorack noise gate that can also invert its behaviour into a compressor and with the 'floor' control it can also be an expander. We've 3 umbrella sections in the video with compression, noise gate and sidechain ducking techniques. Check out the patches and let us know which is your favourite. There's also an exclusive run down of the dirty bass patch on / divkid"

PATCHES // DUCKING & SIDECHAIN
17:48 Big dumb bass ducking - good fun & how to set it up
19:34 Creatively duck ambient FX - I love this mixing/production trick

It's a noise gate, it's a noise suppressor, it's a compressor, it's an expander, it's stereo.

The Specs and Stats:

Width: 6hp
- Attack and Release knob for envelope(s)

- Threshold for suppression/compression (0V - ~8V)

- Floor controls the amount of suppression/compression from -100dB to Unity and even up to +10dB for expanding the louds louder or make the quiets a bit louder.

- Level controls your overall output level

- Gate/Comp switch: When in "Gate" mode, whenever the input falls BELOW the threshold level, the envelope will engage towards the floor setting. When in "Comp" mode, the envelope will trigger when the input rises ABOVE the threshold setting.

-Stereo inputs and outputs. The envelope follower is assigned to the Left input, so the L input can also be used as a sidechain input for a mono signal (into In-R).

- Engage input. This is a gate input for manually engaging the envelope.

- Threshold CV input. This offsets from your knob position.

- Floor CV input. This also offsets from your knob position.

- Duck CV Input. This is an envelope follower input that applies and inverted envelope to the level of the signal. Send a simple pulse or trigger, an actual kick, an envelope, or anything else into this to duck your signal.

-Envelope Output. The envelope Output does not follow the "floor" settings and always outputs a full voltage envelope.

Special thanks to SetonixSynth and many others for really helping make this module a reality.

Creative Eurorack Distortion & How To Use It // HEAD BANGER from Setonix Synth & Robots Are Red

video upload by DivKid

"Distortion has been an essential tool for my music making for most of my life, whether that was playing guitar, working with synths in amps, re amping synths and production stems through pedal FX or smashing mixers, tape machines and other gear I've always found it fascinating and with the options to CV control distortion in modular it's even better!

Head Banger from Setonix Synth & Robots Are Red takes the Swedish Death Metal sound of the Boss Heavy Metal pedal, heavily re vamps it for a wide range of input sources, adds CV control and a creative feedback path and presents itself in Eurorack form. While the name and styling lean on the metal heritage it's been interesting to find a subtler warmth and crunch, synths in tube amp like tones and blown out noisy cassette style grunge for more ambient music.

The Head Banger is Pure Sonic Destruction

video upload by Metamyther

"The Head Banger Eurorack distortion module is a raw, aggressive tool designed for pushing sounds to their absolute limit. This brutal distortion module delivers crushing overdrive and a send/return that can feedback, ensuring explosive walls of sound. The Head Banger adds a unique, high-voltage character that cuts through any mix. Perfect for any system that needs to hit hard."

via Setonix Synth

"The HEAD BANGER Heavy Metal Distortion brings the authentic “chainsaw” sound made famous by the Swedish Death Metal scene to your Eurorack synthesizer! This tonal monster conjures an unholy union between high-quality VCA circuitry and the most legendary distortion circuit in Heavy Metal!

The HEAD BANGER (a collaboration between SetonixSynth and Robots Are Red) gives the modular-based metalhead total control over a wide range of tone parameters: a three-band EQ with 20dB of boost/cut per band, Distortion amount, plus bass boost (Doom) and soft limiting (Crush) switches. These controls will faithfully recreate the classic compressed, grinding Gothenburg sound when fully “dimed,” but they can also provide a great range of saturation reminiscent of 4-track tape and vintage consumer mixers at other settings.

So, users pursuing more mellow sounds need not fret: despite its “heavy metal” tag, the Head Banger offers a fantastic range of distortion flavors perfect for subtly or un-subtly “"warming up” just about any sound that dares approach its input.

But if you thought Jack (Setonix) and Brian (RAR) would simply emulate a famous pedal and call it a day, you would be gravely mistaken! The Head Banger is fully optimized for use with your drums, oscillators, filters and other modular audio effects. It offers full CV control over Input Gain, Feedback amount with Send/Return loop, and Dry/Wet mix. This allows the user to create a dense web of sound and selectively re-integrate it with the original input signal in a number of interesting ways.

With the arrival of the Head Banger, Eurorack users finally have access to the most highly regarded distortion circuit in aggressive music. And now it has more CV control and synth-friendliness than ever! For anyone with a love of harsh, heavy, and/or distorted sounds, the Head Banger is a must-have!"

Glitchy High Speed Switch || Turbocharger by Hakai Labs

video upload by Robots Are Red

"Turbocharger is a 6hp high speed switch between two signals. By default one signal is 5v and the other is 0v. There is an internal oscillator to act as the switching clock. The oscillator also has PWM control. CV control over all parameters. And the 'Do Not Touch' knob... well you'll just have to watch to see it's glitchy goodness.

"Turbocharger is finally here!

Turbocharger at its core, is just a simple super high-speed switch (not a VCA) between 2 inputs. This sounds boring, but the switch is run by a CMOS switch IC capable of switching at extremely high speeds. This, paired with its internal oscillator, with PWM controls, makes for some fun experimentation. The best part is you don’t even have to use the internal oscillator. There is an external clock input that you can patch in your own pulse wave to control the switch.

Turbocharger is an idea that I (Scott Danesi) have had for some time now. After watching a presentation by Jon Sonnenberg (artoftravelogue.blogspot.com) back in the day at one of the early Knobcon conventions in Chicago on Wave Replacement Synthesis, I thought, I could do that in one module but make it crazier. So, what started out as a simple “Turbo” gate for the NT Controller module, now turned into this monstrosity.

The front panel art was created by the talented Aurich Lawson.

New SetonixSynth SkyWave VCO

Feature Rundown w/ Robots Are Red video upload by SetonixSynth

"In this video, Brian aka Robots Are Red breaks down the unique control scheme of the new SkyWave Segmented VCO with audio examples that demonstrate its raw harmonic power."

via Setonix

SkyWave Segmented VCO

The SkyWave is an all-analog voltage controlled oscillator capable of producing many different timbres and unique harmonic behaviors, thanks to an original step-based control scheme which allows the user to dial in completely different wave-shapes and levels for successive oscillator cycles.

The SkyWave uses an internal feedback loop with the clock output of the oscillator triggering a step sequencer which in turn cycles through settings at the frequency of the core oscillator, thus changing the shape and level of the waveform output on a per-cycle basis while also staying in tune and tracking pitch like a typical VCO.

SkyWave Features:

-Complex analog oscillator in 14hp
-Unique “segmented” behavior
-Variable level and waveshape with full CV control and PWM
-Unique “SkyWave” output with sequential waveform control
-Selectable # of steps, clock input and reset for step sequencer
-Audio or LFO output frequency range
-Additional Sine and Clock waveform outputs
-TZFM/TZPM, 1V/Octave and Hard Sync inputs
-Clock division and per-step CV control via Scaffold expander

Technical Specs:
Width: 14hp
Depth: 30mm
Peak Current Draw:
80mA @ +12V, 60mA @ -12V
Input Impedance (All Inputs): 100kΩ
Output Impedance: 1kΩ

"Two fuzz channels based on the fuzz face circuit with a built-in pickup simulator.

Gnarly is a 7 knob beast that will destroy whatever you throw at it. It has many dead zones in the pots that will adjust based on the position of other pots. It's all about finding the sweet spots and living on those fine edges. The transistor pairs on this section are replaceable.

Oomph is a 5 knob bass friendly take on the fuzz face and compliments the upper harmonics of the Gnarly section. Pickup simulator - Fuzz circuits offer unique sound when paired with the inductance of the pickup coils in a guitar. This why it is often suggested to have fuzz pedals as your first in a pedal chain. So we've built-in a coil to simulate your eurorack signal being emitted by a guitar pickup. We've also included a pickup simulator output so you can use it to interface with other fuzz instruments (pedals, modules, etc.). As an added oddness - you can also input your guitar into the pickup sim output (just don't plug anything into the normal input). This will still get you Eurorack level output. Please don't input Eurorack levels into the pickup sim output.

Tips - Experiment with the pickup simulator and buffered signal. Use the PS.Level to keep the signal low, borderline on cutting out. You find lots of joy in the gnarly section by keeping this level at the edge."

Mr. Wavey by Blue Lantern Modules

video upload by Robots Are Red

"What is Mr. Wavey? Well, the boring answer is Mr. Wavey is a 12hp oscillator follower. The fun answer is that Mr. Wavey takes a boring triangle and pulse oscillator and turns it into a waveform powerhouse. With 12 waveforms spanning from the basics like Sine and Pulse, to subs and double ramps, to blended or sequential unique waveforms. Or control Mr. Wavey with 2 separate oscillators for some even more unique morphing waveforms. Or slow things down and use it as a more unique and weird LFO.

via Blue Lantern

"Stack: 2 Level PCB sand which
Caution, not skiff friendly. Compatible with POD cases by 4MS

Does this module require another module?
Yes, you need an oscillator vco module. Best compatibility is a vco with triangle wave and square wave.
Self oscillating sine wave from a VCF module can be used but will not take full advantage of the module.

What does this do?
This module takes two external sources (patched) from an external other module. It wants a triangle waveform and a square waveform.
The internal analog circuitry will make you a variety of wave forms, selectable by knob. You can also blend the output with a slicer and a sub harmonic generator on the second channel.

This module upgrades your boring vco. The wave shapes found on this product is 15+ years of analog circuits I have gathered.

You get two channels of waveform banks. Each can output something separate and different.

There is CV control for the Waveform selection banks, Sub harmonic selection bank, and Pulse Wave Modulation on channel 2."
