Make Noise Introduces PoliMATHS and QXG

video upload by MAKEN0ISE

Check with dealers on the right for availability. User video by Cinematic Laboratory further below.

PoliMATHS [MSRP: $459] is an eight-channel CV and Audio event generator for the New Universal Synthesizer System or any Eurorack modular synthesizer. It uses a single set of controls to generate complex functions at eight independent channel outputs. PoliMATHS’ functions are made up of two components: first, the well-known Rise-Fall envelope with variable Curve (familiar from the original MATHS and Function and 0-Coast Slope); and second, a variable-Shape Oscillation whose amplitude is controlled over time by the Rise-Fall envelopes. This oscillation can be either low frequency for the creation of complex control functions, or audio frequency for native generation of audio events/notes with optional tuned pitch control via 1v/oct control voltage. PoliMATHS also includes output headers for creating pre-patched connections to the control inputs of QXG.

Chain to QXG for immediate eight channel amplitude control


The Quad Stereo Gate (QXG) [MSRP: $239] music synthesizer module is a Four Channel Stereo Low Pass Gate and Mixer. Like the DXG before it, the QXG utilizes a new low pass gate circuit that does not use vactrols. This circuit is 100% analog and its response was arrived at after many months tailoring it to meet or exceed the expectations that have been set by all the vactrol low pass gates that Make Noise has created over the years. Additionally the QXG adds a Vactrol button to select between a Slow, low-pass-gate-like response emulating the decay time of a vactrol (Vactrol button ON), and a Fast precision response that still maintains the gentle filtering characteristic (Vactrol button OFF). Fast response can be especially useful when patching QXG with complex and quickly-changing functions such as those generated by PoliMATHS with the OSC circuit in use. The QXG also includes a Stereo Sum Output with voltage controllable Stereo Spread to quickly route all four channels across the stereo field. Each channel also has an individual output that removes the channel from the Sum when patched. In addition, QXG includes signal and control input headers for creating pre-patched connections from the outputs of PoliMATHS and MultiMod.

PoliMaths & QXG | How does it sound when you know nothing?

video upload by Cinematic Laboratory

"Today MakeNoise has introduced PoliMaths and QXG. My dealer already had them in stock (!) and allowed me to buy them - under the strict condition to keep it a secret until after the official launch video. So I had the opportunity to make a video in one day, without access to any help from the manual or the MakeNoise launch video. Normally I'd do my homework first, but this opportunity is rare. Usually, I can intuitively figure out how a module works, but with PoliMaths, almost nothing is familiar, and what's familiar works differently. So I've probably been using a MonoMaths, but since I decided to get two, there's still a Poli vibe to it.

This is probably one of the worst videos I've made so far, but it's fun to patch in the blind with zero knowledge, and this was the only day I could record, edit and post it. So forgive me for being a MakeNoise groupie. I am biased, but I also think it's for a good reason. MakeNoise managed to make something extremely innovative. I'll make a proper video soon, and I'll figure out what to do with this one later."

WHAT'S THAT THING ?

TRI for Trigger or for Three (!)
COMP for comparator.

It's a module that transforms any signal into triggers and gate signals.

The TRICOMP has 2 sections:
- The first generates triggers (hence the name)
- The second generates classic ON/OFF signals (GATE) combining the configuration of the 3 comparators.

The Triggers section:
When the input signal exceeds the threshold set by the associated potentiometer, instead of switching from state 0 to state 1, it generates a pulse.
The switch allows you to choose when a trigger is generated: either when the signal exceeds, or when it returns below the threshold, or both.
There is also an output that sum the 3 circuits.

The second section is a combination of the 3 circuits, and generate GATE outputs.

Typical use:
All typical use of the comparator function
Trigger generation for complexe rhythmic composition
Waveshaping tool, or complexe PWM.

Instruõ - ceithir | Project Overview

video upload by

"Welcome to the instruōduction of the ceithir.
This is the largest module I have designed to date. Measuring in at 58HP!
It’s been a design project I’ve been tapping away at in the background since Christmas Eve 2024. (It was my holiday entertainment)

I’ve been keen for a while to do a design project reminiscent of my approach ~10 years ago when I was designing the troika.
That was the original Instruō module and came about entirely because I wanted more oscillators in my rack! I actively Timelapse recorded the troika design process and scored it using that original troika to be an extremely nerdy music video!
I did a similar video document project when I designed the tràigh filter later that year.
I did actually record the harmonàig PCB design as well… but that never made a cut because I ended up getting too busy focussing more on the module development side of things more so than the documenting.

For ceithir I have gone a little bit further… I ran timelapse recording for the majority of the process, but also “vlogged” the process and did my best to record key milestones stages.
Over the coming weeks I am going to be publishing these as focussed mini documentaries that focus in on particular design stages.
Some of these include:
• sketching the interface layout/hardware components and then designing the interface graphics
• hardware layout considerations
• troubleshooting initial prototypes
• first power up and then calibration/testing of the first full hardware iterations

As Instruō has grown over the years I have enjoyed collaborating with this team of designers. Sharing ideas and learning from each other is a big part of how we create. I hope some of this series might serve as some form of reference to anyone interested in module design. I feel like it’s becoming more and more common for bands/artists to produce some behind the scenes content surrounding writing and production of new albums. I’m hoping the format translates to some module design bts content. It is perhaps not a step by step tutorial, but I have tried to capture the process quite comprehensively.

This module is a ridiculous one! I don’t know what the current next step is beyond a handful of them existing for my own personal rack(s).
If there is interest, please let me know and I can see what’s possible. This thing is definitely not suited for large scale production! But I am very excited to see what people do with it.

Thanks for reading.
Please feel free to join us on Discord and say hi!

Joranalogue Audio Design Introduces WALK 4 & WARP 1 Eurorack Modules

Press release follows:

"Emerging from the Joranalogue labs are two exciting new additions to our ever-growing series of fully analogue Eurorack modules. Let's dig into this dynamic duo.

First up: like a sample and hold with a master's degree, Walk 4 combines four analogue accumulators with a clock generator, four white noise sources and an auto reset to create a 10 HP voltage stepping, arpeggiating and random walking juggernaut.

With full voltage control and independent value and trigger inputs for each accumulator, there’s always more stochastic patching to explore ahead. And if you need a reliable master clock source with a huge range, 1 volt per octave tracking and external reset—that’s covered, too.

Meanwhile, its partner Warp 1 is a new breed of analogue waveshaper, based on a precise mathematical relationship between input and output, governed by a variable power function.

From subtle timbral colouring to wild hyperbolic distortion, it provides a level of control that’s unprecedented in waveshapers, combining meaningful parameters, clear LED indication, complete voltage control and DC to supersonic operation.

Friend of the brand BRiES already went and made a couple of excellent overview videos—be sure to check them out below. And, if you want to be among the very first people to patch these modules up, drop by our booth at Machina Bristronica in Bristol (UK), on Saturday the 27th or Sunday the 28th of September!"

Discover the POWER of Feedback with Isobar's Umbra

video upload by Metamyther

"Discover Umbra, the cutting-edge stereo feedback accumulator designed for adventurous sound designers, new from Isobar. With its unique approach to feedback through a send and return effect loop, Umbra opens up massive sonic possibilities, delivering everything from subtle textures to chaotic walls of sound."

00:00 - Intro
01:20 - Vhikk X Example
04:46 - Drum Example
06:49 - Saturation
07:35 - Multigrain
08:17 - Cursus Melody

"Umbra is a dual channel feedback processor with three discrete transistor core VCA pairs. Route any eurorack-level effects, compressors or filters through its send/return paths to create feedback loops ranging from subtle textured echoes to howling walls of sound. The input level VCA is positioned before the feedback circuit, allowing time based sounds to fade naturally when the VCA is closed. A soft clipping stage after all feedback keeps levels controlled while adding nonlinearities and character. The left-right channel normalling allows for both mono-to-stereo or true stereo operation.

Features:
- Discrete transistor core VCAs for input gain (L and R), VCA pair for return gain, and VCA pair for feedback amount.
- Switchable between stereo operation and serial mono operation, where the output of the left channel enters the input on the right channel, doubling up on feedback and processing, indicated by the color of the LEDs. Orange L and R channels = Stereo operation, Orange L channel, Blue R channel = Serial operation
- Asymmetric diode soft clipping distortion at output.
Level LEDs for input level and return level, to keep feedback, drive and gain under control.

Uses:
- Adding a filter, filter bank, delay, reverb, waveshaper, or any other effect into the feedback loop.
- Heavy soft clipping distortion.
- No input feedback mixing.
- 3 stage VCA with distortion"

"the zi51 is the metasonix r51 circuit, used with permission, redesigned to take 6ak5/5654 tubes (only use 6ak5 or 5654 tubes in this module) and added feedback.

the input knob controls the audio input level. distort controls the bias adjustment of the distortion level.

vca adjusts the amount of cv applied to the vca cv input.

you need to have a cv source applied to the vca cv input jack to get the most results from the vca knob.

feedback controls the amount of signal fed back into the input.

a modulation signal of at least 5v is recommended to insert into the vca cv input.

the module functions best when a modulation source is fed into the vca cv input to fully open the vca level of the module.

the distort and vca knobs interact with each other and the more voltage that is applied to the vca cv input the more effect the distort knob has when turned.

it is recommended to let the module warm up several minutes before operating and to start with settings as described:

Hacking the TIME-SHIFTER - Eurorack module

video upload by LARIX ELEKTRO

"A small addition to the TIME SHIFTER module:
Add a CV input to the MAIN-SHIFT parameter.
A CV input to this parameter hadn't been planned, as in the intended use, it wasn't relevant.
But actually, why not? That's the whole point of being modular: going where the manufacturer hadn't thought!

Ok, it's a bit makeshift, but it works…
More info on the site:
https://www.larix-elektro.com/PRODUCT...

Modules used:
LARIX ELEKTRO 4TOMS for the toms! obviously ;)
LARIX ELEKTRO Ritournelle CV Generator + Shift-R for the rhythm
LARIX ELEKTRO Ritournelle CV Generator (another one) for the CV controlling the MAIN SHIFT"

"WHAT'S THAT THING ?
The Time-Shifter is a delay for gate or trigger signales.
As all good time machines it can delay after and before (!).

The first idea is to find a way to build a swing or a groove.
So to decide which steps of which track is decayed, and how much.

To do this, it is necessary to be able to shift the events after and before. But before, we can't predict when an event will appear...

The solution is to decay everything, and then, decaying less than the others events.
So comparing to the new decaying events, it will sounds like it appear before.


The MAIN SHIFT defines this new reference.
So if you enter the main CLK signal into the input, the output of this circuit can be used as the new CLK reference.

The four circuits A B C and D works according to the value of the MAIN SHIFT reference:
- When the knob is centered, the time decay is the same.
- Left, means less time decay, so the event will appear before.
- Right, means more time, so the event will appear after.

Extend your module:
The module can be enriched by one expansion modules:
- The AttV-4 adds to the CV entries an adjustment of the CV value by an attenuverter.
The connectors on the back of the module save connectivity at the front.

Typical use:
- Groove (or swing, etc.) controlable by CV (!)
- Realignment of gates sequences.
(When using multiple sequencers with different latency)
- Signals sequencing adjustment.
(Be sur that a RST arrives at the right moment, for example)
(Be sur that a your S&H module sample after signal stabilization, for example)"

ADDAC Perc VCA and Friends Jam

video upload by Molten Music Technology

"Really liking the Perc VCA for the simplicity of its built in decay envelope and ability to grab a bassline with the minimum of fuss. Here's a quick demo and I hope to do a full review soon."

"While deep in its soul there’s a standard VCA with exponential response that can be used as such, in its heart pulses an AD envelope with a sharp attack and a variable decay internally connected to the VCA control input. When it opens its mouth it can whisper in your ear but don’t let this soft demeanor fool you, if driven to the extreme it will show its teeth and gnarly bite and chew on your cochleas with all its might.

The AD envelope has a fixed short Attack, just enough to avoid the typical “click” that happens when using a Gate signal to control a VCA, while the envelope Decay can be controlled via its knob or voltage controlled using the CV input and attenuverter.

We named it Percussion VCA as most percussion intruments have sharp attacks with variable decays just as its AD Envelope however it can be used for any purpose where a VCA is needed including for CV signals due to it’s DC coupled signal path.

Furthermore it also allows to be driven from a simple Gate signal while controlling its decay. This way it’s easy to plug a noise source, vco or any audio and turn that source into a percussive element."

Arcaico Instruments Introduces GLADIO Dual Slope Function Generator

video upload by Arcaico Instruments



"GLADIO is a dual generator of modulatable envelopes and slopes, inspired by the great classics of modular synthesis but reinterpreted according to Arcaico's vision.

Each envelope is a blade that sculpts time, a malleable flow that can become an envelope, a low-frequency oscillator, a complex shape generator or an interactive modulator. The name GLADIO recalls the ancient weapon, a symbol of precision and power.

OPERATING MODE:

AR (Attack-Release)
The envelope starts with the trigger and follows the attack and release curve. It is not affected by the gate duration.

ASR (Attack-Sustain-Release)

The envelope remains ‘high’ as long as the input gate remains active.

When the gate is released, the decay phase begins.

CYCLE
Transforms the generator into an LFO oscillator variable from 0.2 ms to 23 minutes.

Ideal for slow modulations or audio-rate oscillations.

FUZE
Envelope B follows Envelope A with a 90° phase shift.

Create quadrature modulations useful for stereo effects, timbre rotations and complex patterns.

EOC (End of Cycle)
Output that triggers on each completed cycle.

Can be used to synchronise other modules or to auto-trigger the envelope

SUM OUT.
use this output to mix the two envelopes and create new textures for your envelopes.

Biopower Audio Introduces Cerebellum Logic Matrix

video uploads by Biopower Audio

"CEREBELLUM is a Boolean logic matrix for Eurorack modular synthesizer. It can craft complex polyrhythms, arrange generative structures that evolve over the course of a piece of music, and even produce gnarly timbres when combining audio rate signals.

The module a final prototype. Please learn more and sign up for pre-orders at: www.biopoweraudio.com/cerebellum

The module accepts inputs on three rows, which may be operated upon by signals from four columns before output. An operation is active when a latching 15mm LED switch is engaged at each node, which displays the new signal. A second switch allows a choice of AND or XOR operands.

To extend the module’s functionality, each column provides a clock divider and static +5V “on” and NOT invert switches. The dividers alternate between a binary counter /x^2 (2 through 128) and a decade counter /x (integers 2 through 8) paired with a LATCH flip-flop.

A single signal at IN ALL addresses all columns, which have outputs after their division and invert operations. All dividers receive individual resets and RST ALL. Columns 1, 2, and 3 are normalled to rows A, B, and C respectively, allowing the creation of seven inter-related signals from one input.

CEREBELLUM is 30 hp and 38mm deep. Max current draw is 100ma (primarily from LED use!)

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!"

Filternator

Playlist:

1. "Filternator" module introduction

A no-talking introduction to our new module. Is it a Filter? Is it a Resonator? Yes...with a difference.

2. Filternator Stereo demo- no talking

Using two Filternator modules in parallel for stereo and the cool sounds you can make.

3. Filternator Drum & Guitar

What happens when you run a drum machine or a guitar through this module? Let's find out.

Filternator

"Is it a filter? Is it a resonator? Is it a filter bank? Yes- the new Filternator module is all of the above…with a difference. When developing the module and hearing how it treated signals, it was obviously filtering, but with high resonant peaks that were stronger than the incoming signal, at which point it was resonating up a storm. So what to call it? It’s resonating as much as it’s filtering, so we called it the Filternator!

It’s simplicity itself to use: plug your audio in the input, and the output goes to whatever you like down your signal chain. Use the wet/dry mix knob to control the amount of “filternated” signal you’d like to hear. Then comes the fun part: chose a mode, and start messing around with the switches. There’s a choice of three switches for the capacitors, and three switches for the coils used in the circuit. They can be used in any combination to set the filter frequencies and resonant peaks. If you like, automate the mix control with an external CV source. The one thing you don’t do is power it up…except for the external control voltage for the wet/dry mix, it’s completely passive! But unlike other passive filters, this design doesn’t drag down your signal level with resistors in the circuit, because there aren’t any. By using inductors instead, the signal doesn’t get attenuated as it does in a standard passive filter. Instead, it will actually boost signal levels as it nears the resonance peak.

Talk about skiff friendly, not only does it not take any power, but it’s nice and slim, just 12mm deep behind the (nice and thick aluminum) faceplate."

"Triquetra is a linear feedback shift register module, with three independent registers that have their own Gate and CV output. The clock for the second and third register are normalled to the first, but can be supplied with their own clocks to get a wide range of versatility from the module. A clock source is required to generate bits. The toggle switch will change between Looped and Free Run mode.

Each register has an attenuator for the CV output.

The Gate mode can be switched from a 50% clock cycle when the last bit is high, to a high output as long as the last bit is high. This gives the result of switching between either a “Trigger” style or “Leggato” style Gate. The Gate mode can be switched at any time by pressing all three buttons at the same time.

Each button corresponds to the three registers, and will cycle through the bit generating algorithms (seven in total). The LED will cycle through different colors corresponding to the following:

RED = LFSR1

GREEN= LFSR2

RED/GREEN= Small Number Modulus

BLUE= Fibonacci Sequence

RED/BLUE= Prime Number Sequence

GREEN/BLUE= Large Number Modulus

"Commonly audio Crossovers split an audio signal into several frequency ranges so that each resulting signal is adequate for the speaker drivers they are connected to, usually low range is sent to the big woofers, mid range to smaller woofers and high range to the tweeters.

Here we introduce our ADDAC607,a mono 3 band Crossover featuring 4 pole, 12db Sallen-Key active filters and volume controls for each band. Although ADDAC607 operates in Mono (for Stereo signals two modules can be used) there are 2 audio inputs that allow an easy way for Stereo to Mono summing. The [MONO SUM OUT] carries this summed signal. This output is pre-gain and can also be use as a buffered Thru output.

The possibility to split the signal into different bands makes possible several usefull processes, as examples:
- Independently process specific frequency ranges like adding delay only on the high range band
- Split a signal to feed 3 compressors for multiple band compression
- By controlling the [GAIN] knobs they can act as “kill” switches in DJ mixers to remove a whole band from the mix

This module is also a great companion for our ADDAC220 Dual Envelope Follower+ allowing to extract the dynamics from any signal in a focused frequency range allowing to, as an example, separate a kick drum from a snare.

There are three switches to select the bands operating ranges:
2KHz, 4KHz and 8KHz for the high range
370Hz, 620Hz and 1KHz for the low range

The three [GAIN] controls set the volume for each band. At noon they are unity gain, fully CW they are x2 amplifiers."
