Djupviks Gats // Grainy Reverb // Angry Filter

video upload by Lesjamusic

"‪@vikingsade‬ Djupviks Gats is a grainy reverb feeding into a wasp-style bandpass filter, with sample-and-hold modulation built into the signal path. By default, it samples your incoming audio to modulate the filter cutoff - creating stepped, glitchy textures that respond to your playing dynamics. The offset control lets you shape that response from aggressive ducking through to keeping the filter permanently cracked open.

In this video I walk through the module and show a couple of patches demonstrating what it can do.

Features:

Grainy reverb into wasp-style bandpass filter
Internal sample-and-hold with adjustable clock
S&H can sample audio or external sources
Bipolar offset control for shaping filter response
Pre/post feedback switch
External clock sync"

Gene CHROMAGENE - First Look

video upload by Gene Synths



"Pre-order at http://genesynths.com

Sound recorded directly from the back of the synth (No added effects / eq / reverb etc).

CHROMAGENE is an all analog, stereo polyphonic synthesizer with two halves. One half is an 8 voice 2 VCO polysynth where every oscillator can be tuned independently or transposed together, the other half is a polysynth that uses the Ring Modulated output of each pair of oscillators as its signal source.

This wide range of sound sources along with two analog filters and an on-board sequencer give Chromagene a wide palette of tones and textures.

Inspired by the earliest polysynths of the 1970s, it is fully polyphonic
(all 16 notes can be played at the same time), can be tuned to any scale or tuning,
is multi-timbral and touch sensitive.

The instruments key contacts are Immersion Gold plated and non-corrosive.

At the top, there are 16 tuning controls for the 8 pairs of oscillators. Each tuning control has a momentary pitch bend touch sensor below, so you can articulate each note individually. The top row of tuning controls (VCO-1) also shifts the oscillator below it, but the second row of tuning controls are independent. This allows you to preserve the tonal relationship by using the top tuning controls, or change it by detuning VCO-2.

These tuning controls allow you to tune the 8 pairs of oscillators to any scale, from a standard equal tuning to any microtonal, non-western or even unison tuning.

VCO-1 has a Pulse Width Modulation control and each set of oscillators has a master tuning control and an individual LFO control.

The 8 analog ring modulators take the VCO signals and multiply their output. VCO-2 is converted to a triangle pre-ring-modulator so that the ring modulated signal is fully continuous and not binary like pseudo-ring-modulators in some synths. This means you can create virtually any waveform by carefully tuning the input VCOs, and an endless variety of tones can be generated for each note individually.

The two filters, which can be panned from mono to full stereo using the panning control, are all-analog all-transistor low-pass VCFs, with individual cutoff, resonance and envelope-mod controls. The envelope amount controls go from negative (inverted) to positive. VCF-1 has mixer controls for VCO-1 and 2, and VCF-2, which is for the Ring modulated notes, has LFO cutoff modulation and Panning.

The 16 independent envelope generators have Attack, Decay, Sustain and Release controls.
The sequencer can be internally or externally clocked. Custom sequencer configurations can be set up, get in touch.

The synthesizer is built into a hand-made wood case.

Oddment ODD-1 Build Update & Demos

video uploads by oddment

Playlist:
1. ODD-1 Overview: Playheads

For a long time now we have tried to live by the words of the great Michael Bolton from the movie Office Space, "why should I change when he's the one who sucks?" But language evolves, and unfortunately, the word “grok” has taken on associations that are problematic. Oddment has evolved too. Starting from one quirky product idea, in 3 years we have grown and are now ready for manufacturing and fulfillment of this product, with ambition to make it the first among many. So with much consternation, we have decided to drop the name groc. When we thought about a new name, we thought that what we have is a little unusual, perhaps a little outside the norm...you might even call it, the ODD-1. This is the first in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off half of the encoders that control the granular synthesis engine - the PLAYHEADS function. Here you can control the level, starting point, tuning (aka pitch adjustment) and playback speed for up to 4 different granular playheads. The auxiliary functions available on the touch screen introduce random variability in different ways.

2. ODD-1 Overview: Grains

This is the second in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the second half of encoders that control the granular synthesis engine - the GRAINS function. Here you can control the size, spacing, left-right placement, and grain window shape. Each control also has a related function, introducing grain size variability, spacing jitter, binaural scatter, and a front-back bias for the window shape. The auxiliary functions available on the touch screen control a bandpass filter that can be randomized per grain and adjust whether grain size is regulated in the source sample or in the output signal, which can have a big impact on sound characteristics.

3. ODD-1 Overview: 03 Envelopes & Time Path

This is the third in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the ENVELOPES function. Here you can control the note amplitude envelope and timing, access 3 envelopes that can be used as modulation sources, and use our unique TIME PATH feature to dynamically adapt the playback speed.

4. ODD-1 Overview 04: Sample

This is the fourth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the SAMPLE function. Here you can choose a sample from the factory library or user-uploaded samples, control the playback mode and the section available for granulation, play and hold notes, set loop points and interact with pitch, tempo and channel information of the sample. We also show the auto pitch and tempo alignment features.

5. ODD-1 Overview 05: LFOs, Macros, Patching

This is the fifth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the LFOs, Macros and how to create modulation connections. There are 4 LFOs, 3 Envelopes, 4 Macros (assignable knobs), 4 Control inputs and MIDI information that can all act as modulation sources. Any parameter on the device is a parameter destination. Unlimited connections are made by holding down a destination parameter and then pressing or twisting a modulation source.

6. ODD-1 Overview 06: Filters, Saturation, Echoes

This is the sixth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the Filters, Saturation and Echoes modules. Two filters and two saturation modules per voice, both with multiple types of processing and modulatable parameters, allow for transformation beyond the granular engine. Two echoes sections with filtering and distortion in the feedback loop and fully modulatable parameters make ODD1 worthwhile just as a modular effects rack!

7. ODD-1 Overview: 07 Layers

This is the seventh in a series of videos to show all of the ODD-1's functions in more detail. In this one we show the dual Layer functionality. Essentially the entire system is duplicated so the ODD-1 is like having a dual modular systems, each with a polyphonic granular engine feeding two filters and two non-linear processors per voice, with 3 envelopes, 1 time path, 4 LFOs, 4 Macros and a independent modulation matrix per layer. In these examples we also remind that granular can easily do subtractive-style synthesis when using a basic waveform as the source sample.

8. ODD-1 Overview 08: Reverb & System

The final video in our eight-part series on the ODD-1's functions focuses on the upper-left row where we have global volume, system-level reverb and can work with banks of patches.

The reverb is a classic matrix-style parametric reverb. Think of it like a whole set of interacting delay units with slowly modulating delay times. Ok now that you have that in mind, that's it, that's what it is. It sounds sweet.

If two layers of modulating, granular goodness with a fantastic reverb on top wasn't enough, how do banks of patches to store every twist and connection sound?

And from their newsletter:

What’s in a name?

For a while now we have tried to live by the words of the great Michael Bolton from the movie Office Space, "why should I change when he's the one who sucks?"

But language evolves, and unfortunately, the word “grok” has taken on associations that are problematic.

Oddment has evolved too. Starting from one quirky product idea, we have grown in three years and are now ready for manufacturing and fulfillment of this product, with ambition to make it the first among many. And with much consternation, we have decided to drop the name groc.

When we thought about a new name, we thought that what we have is a little unusual, perhaps a little outside the norm...you might even call it, the ODD-1.

And we plan to keep that off-beat attitude. We hope that brightly-colored friends, ODD-2 and ODD-3, will be along to join ODD-1 after not too long.

Build Updates

We have a lot of exciting progress to report since the last time I wrote. Hop over to our YouTube channel to check out a build update video and some in-depth functionality demos.

We debugged and fixed several problems with the circuit board including the power-up, line input and output, and noise on the control signal inputs.

We got several bids from contract manufacturers in the U.S. and around the world and selected Soldered, based in the E.U. They came highly recommended, and we think their experience will be a huge asset as we go into production.

We worked with Martyna Alexander to tweak the graphic design of the front and back panel. We are thrilled with the updates, including our new company and product logos.

We have first iterations of our custom firmware, enabling full functionality of the device and full USB connectivity to a host computer.

We have completed first versions of the software that include all audio, MIDI and system functionality we intend to support for the release. After many months of playing and testing we re-organized a few functions to expand both the number of concurrent grain “playheads”, and to support banks of patches intended for convenient switching and management in live performance.

New SEOK Eurorack Modules - DRIPS, AT, M22, & ROTARIES

SEOK - DRIPS – Voltage Controlled Analog Filter [DEMO no talk]

video upload by SEOK synthesizers

via SEOK Eurorack Modules

DRIPS

A warm and bubbly 12 dB/oct analog Eurorack filter with dual voltage control of frequency. Low-pass, band-pass, and high-pass outputs in one compact 8 hp module.

With external signals, the filter stays soft, clean, and precise. Adding resonance gives a liquid acid tone (like a good filter coffee). When driven into self-oscillation, it produces sine waves perfect for deep bass, kicks, and percussive sounds.

An integrated VCA placed after the filter lets you shape both tone and dynamics in a single path – precise when clean, saturated and raw when pushed.

Raise the offset to move seamlessly from rhythmic sequences to heavy drones.

Background:
We wanted to build a versatile Eurorack VCF/VCA with a balanced function-to-HP ratio. For us, ergonomics are as important as function – it should feel intuitive and spacious around the core controls.

And since we’re from Sweden, we couldn’t resist adding a little warmth.

Olivella Modular Furia | Discrete transistor filter & VCA

video upload by Tom Churchill

"Olivella Modular's Furia is a 4-pole transistor ladder filter, based on the E-mu Modular 2100 LPF designed by Dave Rossum in the 1970s, paired with a discrete transistor VCA with tons of gain. There are no ICs anywhere in the audio path, so it has an authentically vintage sound, and it distorts in a really musical way. In this video, I give an overview of Furia’s signal path and controls and build a few patches to demonstrate how it sounds.

Chapters:
00:00 Intro & patch previews
01:42 Furia overview
07:41 Pinging the input
09:41 Overdriven acid
13:54 Furia as a low-pass gate
16:39 Dirty drum machine preamp
22:00 Audio-rate cutoff modulation"

"FURIA is a discrete 4-pole ladder filter and a transistor VCA with a variable response CV curve control. It isn't 'just' a filter, but an all-around vintage-sounding sculpting and performing tool.

The filter section is based on the venerable E-mu Modular 2100 LPF, but unlike it, there're no ICs in the audio path - even the output stage op-amps are transistor based, both in the VCF and VCA sections.

As its name suggests, FURIA has plenty of gain on tap: the INPUT LEVEL knob starts distorting around 9 o'clock and interacts with the resonance in interesting ways, while the VCA and its X10 input switch can transform the filtered sound into nasty acid basslines - no external distortion required.

You can use the filter and VCA independently or in series, with an AMP CV input that's normalled to the FREQ CV input to facilitate a LPG-like configuration.

The AMP IN allows you to mix a signal into the VCA after the filter - for example, a higher register FM'd or wavefolded sine wave with a bassier filtered sawtooth from the LPF stage.

Unlike most ladder filters, FURIA's LPF is fully DC-coupled, though internal offsets may produce slight clicks at the VCA stage.
To remedy that, the DIP switch on the back lets you selectively AC-couple the VCF and VCA inputs and outputs, reducing clicks and offsets for audio purposes. It also allows you to change the VCF -> VCA normalling for series, parallel or independent use."

Minimal electronic with glitched piano sound : Between the waves 2025-10-26 by atnr

video upload by atnr

"A piece created with norns shield and modular synthesizer — an ambient electronica work where glitch-processed piano tones emerge within waves of sustained electronic sound.

On the norns shield, the barcode script is used to record and play back synth pad performances from the ‪@SequentialLLC‬ Prophet-10. The connected ‪@KorgOfficial‬ NTS-3 adds reverb and occasional tremolo effects.

In the modular synthesizer, a piano performance is recorded into Morphagene, which is then modulated with CV signals from Quad Function to create glitch variations. The modular output is split into two paths: the original signal from Morphagene, and another processed through a Clouds clone. The original path is further enhanced with ‪@ChaseBlissAudio‬ MOOD MKII, applying micro-loop effects for additional glitch textures."

Morphor ECHON 6 BBD Resonator Synth Now Open for Pre-Orders

Morphor's ECHON 6 pre-orders are now open at Perfect Circuit

Press release follows:

Morphor marks upcoming availability of ECHON 6 as world’s first polysynth based around analogue BBD resonators by announcing opening of pre-orders

GHENT, BELGIUM: having twice turned heads and opened ears thanks to show-stealing showcases at SUPERBOOTH25, May 8-10, FEZ-Berlin, Germany and Machina Bristronica 2025, September 27-28, Bristol, UK, Morphor marks upcoming availability of its eagerly-awaited ECHON 6 — being billed as the world’s first polyphonic synthesizer based around BBD (Bucket-Brigade Delay) resonators, building upon the Belgium-based collective of artists, engineers, and musicians with a passion for creative sound experience and radical acoustic ideas’ illustrious Eurorack expertise in that area as its inaugural standalone (rack-mountable) desktop design — by announcing the opening of pre-orders as of October 23…

As an ANALOGUE POLYPHONIC MULTI-TIMBRAL BBD SYNTHESIZER — helpfully highlighted by the on point wording worked tastefully into its fitting front panel design’s execution, ECHON 6 brings the principals of modal synthesis into the analogue domain. Far from reimagining a digital concept with modern analogue circuitry, it readily redefines how resonance and excitation can interact. And as the world’s first polyphonic synthesizer based around BBD resonators, no less, each of its six voices features a discrete BBD RESONATOR that tracks the keyboard, producing organic overtones and complex harmonic depth. Duly allowing its users to excite those resonators in creative ways, ECHON 6 can generate anything from plucked and bowed strings over leads and basses to big pads and evolving soundscapes. Combining comprehensive multi-timbral capabilities, a 9 x 32 modulation matrix, a full analogue signal path, and a one-knob-per-function approach, ECHON 6 ultimately unites experimental sound design with classic polyphony. Indeed, its architecture invites exploration at every stage of that analogue signal path.

AD ENVELOPE + VCA WITH A BITE | ADDAC System - ADDAC816 Percussion VCA

"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."

Multimode Tube Filter, Saturator & Beyond! // VAMP from Apollo View Modular

video upload by DivKid

"With Vamp Apollo View modular took the early Korg MS-20 and MS-10 filter designs, which favoured non-linear character over stability and control, they added more character with a tube input saturation stage and tube resonance feedback path, further output clipping stage options and then designed in modern stability and control. I joke in the video the filter is so rubbery it might as well be wearing a gimp mask. Vamp is also multimode with low pass, band pass and high pass modes with routable pre/post VCA and gain option, smart normalled CV options and prevision circuitry to turn it into a full single module tube voice, killer kick drum and more.

VAMP
8HP Multi-Mode LP/BP/HP Sallen-Key Filter with Tube Saturation & Distortion

VAMP is a multi-mode analogue filter that gives you low-pass, band-pass, and high-pass responses in a compact 8HP design. At its heart lies a classic Sallen-Key topology supercharged with real vacuum tube (12AU7) saturation and multiple stages of clipping, letting you move seamlessly from smooth, hi-fi filtering to snarling, overdriven character.

One half of the tube is used to saturate the input, while the other half provide MS-20-inspired resonance limiting (tube, not diodes). With FLOW placing the VCA pre-tube or post-filter, and FANGS selecting Off / Soft / Hard output clipping, VAMP ranges from subtle warmth to ferocious harmonic destruction.

The First Synth with a Cause

GS Music leads with its synths in the fight for breast cancer prevention and early detection

After 11 years of dreaming, GS Music finally brings to life a project that speaks to the very heart of its team: supporting breast cancer awareness and early detection. The Argentinian brand — the first to manufacture polyphonic analog synthesizers in Latin America — launches a limited edition of the Pink E7, a synth that doesn’t just resonate sonically but vibrates with purpose.

“67% of our assembly team is made up of women. For us, it’s important that our actions align with the DNA of our team,”

says Elena Epuin, founder of GS Music and the main driving force behind this heartfelt campaign.

Breast cancer is a disease that can affect women at any moment in their lives. That emotional proximity to the cause is what led the team to finally bring an old idea to life — one that had been evolving for years.

A synth with soul (and heart)

“The idea of the pink synths has been in our heads for a long time,” Elena explains.

“For us, it’s vital to keep our synths connected to the human side of things. The E7 doesn’t just have a great sonic soul — it has a human soul too. I believe that’s why our clients stay in touch long after buying their synths.”

The result is a limited run of four Pink E7 units, in a soft baby pink tone with transparent iridescent knobs that perfectly blend tender visual design with raw sonic power. A true analog beast — seven voices of polyphony, multitimbral, with a fully analog signal path — now with a cause beyond the music.

All proceeds from the sale of these four special units will be donated in full to a leading oncological institution in Buenos Aires, reinforcing a campaign that goes far beyond sound.

A Batman, an idea, and a city

As a creative twist, Elena had an unexpected idea: she invited Buenos Aires’ own Batman influencer, with over 60,000 followers on Instagram, to join the campaign.

The result was an iconic and moving encounter that brought together synths, social awareness, and a local superhero who represents strength, visibility, and commitment to real-world causes.

And yes, here are the photos from that unforgettable moment — even Batman showed up for this.

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.
