New Uses for Old Circuits Series

"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.

In this video we look at the al-Jabr (الجبر) patch - a patch that injects inverted signals into the feedback loop to tame chaotic behavior, and uses the rate of change (derivative) of a signal as a cybernetic regulator."

'SIEGFRIED' | VC RES EQ + VBR | Serge Modular | Episode 11

video upload by Cinematic Laboratory

"The VC RES EQ is big, very big and the VBR (Variable Bandwidth Filter) makes it even bigger. But even then, it's not a combo that would appeal to the 'mainstream' eurorack audience. The 4U version joins both modules under one panel and is called 'SIEGFRIED', inspired by Wagner's dragonslayer in the classic Ring des Nibelungen epic 15 hour opera which ends in Ragnarok - the Apocalyptic end of the Gods. Now that's a much better setting! We need mist, heroes, dragons, Gods and something close to Mount Doom. Tolkien didn't like Wagner's work at all, in fact, he hated it. With this eurorack combo you can now create your own adventure, keep the ring for yourself and throw Frodo into Mount Doom.

This is one of my favorite videos so far and I just LOVE the sound of the VC RES EQ. The VBR is added to tame the harsh sounds that often come from the 'pet dragon', but if you play it with your fingertips, prepare for myths and legends.

As always, this video is not sponsored, but I am enjoying a small 'artist discount' from Random*Source because I make videos like this. Dear Serge, if you're watching this, THANK YOU for being Serge and thank you Random*Source for keeping the legend vibrant, alive and kicking."

New Uses for Old Circuits Series

"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.

In this video we look at the textbook example of a nonlinear and chaotic system - the logistic map. We explore how to use the Serge as an analog computer to take numbers and multiply, add, and subtract them, and further how to create a discrete feedback sequence from them.

Building a Serge BESTIA III panel with Serge Eurorack

video upload by Cinematic Laboratory

"I am aware my Serge series is a bit of a niche in eurorack, but I feel it shouldn't be. They may seem complicated, or maybe too simple with the minimal grid panels and the lack of leds. Maybe even eh.. underwhelming compared to the competition. Also, many Serge videos focus on the raw voltage paths, so many of them just scream, tick and growl. This video is no exception. However, if you truly want to know what modular synthesis is about to enjoy absolute voltage freedom (a challenge by itself) a Serge system can teach you a LOT about the gear you already have - even when you never get to own single Serge module. As always, I am not trying to sell you anything, I am not an influencer and I no longer care (too much) about the latest hype modules anymore unless it blows me away. This is now an educational channel. It always was. And it's my duty - and privilege - to try and show you why Serge changed the way I patch. If you don't know what you're missing, you won't miss it. And if none of this appeals to you, that's also a valuable 'lession'. Your personal experience is all that matters - and the music you love most.
I am still a beginner, with Serge you may always know nothing between your previous and next patch. But if you're looking for magic, there's a lot of magic hiding behind those modest panels."

Exploring the Serge Modular Stereo VCFQ #sergemodular #eurorack #modularsynth

video upload by The Machines Won

"Exploring the legendary VCFQ filter in stereo!! It's a perfect filter to pair with the medusa. I hope you enjoy listening to these patches as much as I enjoyed making them.

There are some jams at the end if you want to hear more musical applications with the filter. A few pinging sections of course, some pads, ambient, industrial and synth wavey goodness.

Lots to explore with this versatile filter, now made better in Stereo!"

Nonlinearity And Feedback

video upload by La Synthèse Humaine

New Uses for Old Circuits Series

"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.

In this video we look at simple feedback systems and explore linearity and nonlinearity. We see how basic audio feedback through a linear system (basically a volume knob) can accentuate or attenuate what is already present in a sound. But sending the feedback through a nonlinear system transforms the sound into something else entirely."

Deep dive into the PCO aka Precision Oscillator by Serge Modular

video upload by Stazma

"Today we check out the one of the most (seemingly) simple building block of the Serge Modular: the PCO aka Precision Oscillator.

This module does have some tricks up it's sleeve and is not as simple as it seem especialy, when it comes to it's sync behaviour, but overall it's a great sounding analog oscillator that is well... very precise hahaha.

This makes it ideal in this dual configuration to be used as a classic "carrier" / "modulator" configuration with itself and with other modules.

Have fun!"

Stereo VCFQ | Serge Modular | Episode 10

video upload by Cinematic Laboratory

"Serge Modular made the legendary VCFQ stereo. While having three inputs and six outputs, the AGC (Auto Gain Correction) and Notch out had to go. In normal operations, it's a true VCFQ which you can use in both mono and stereo patches. The AUX input can have dramatic results when self patched as feedback. I'll be using the VHIKK X in this video as the primary source, a source that doesn't need an extra filter to sound good. In fact, this creates the challenge of which module dominates which. In general, it's always the module that cuts the other one's frequency range. Finally, I'll use my mono VCFQ and the ST-VCFQ to process the X's L/R channels independently. Now the fun begins :)."

New Uses for Old Circuits Series

"New Uses for Old Circuits is a series looking at linear and nonlinear processes in the modular system.

In this video we get right to the heart of the matter and discover what defines a linear system (and therefore what defines a nonlinear system). Linear systems are systems that obey the laws of homogeneity and superposition, whereas nonlinear systems are ones that break these laws."

In this video we go through every module in the Serge synthesizer to discover which circuits create an inversion at the output. As a result, we create perhaps the most boring synthesizer video on YouTube, but we also lay some important groundwork for the future - creating a conceptual map of the Serge that will be very helpful in feedback patching.

Apologies about the periodic focusing issues - I'm still working on it :)"

Serge Modular Synth Res EQ | Feedback Drone

video upload by Akihiko Matsumoto

"Serge Modular Synth (Sample Pack) https://akihikomatsumoto.sellfy.store... Created entirely with the unique sonic character of Serge modular systems

About this Pack
Serge Tcherepnin once described his instruments not as tools but as open systems for discovering relationships between sound and control. The Serge Modular Synth is built on this principle. It does not simulate acoustic behavior; it generates its own logic of vibration. Each circuit is an experiment in how voltage can behave as if it were alive. 　

This sample pack captures that principle through Random Source’s modern Serge system, combining the GTO, GTS, and Res EQ with the reissued 50th Anniversary Paperface. The recordings move fluidly between the precise tension of Eurorack signals and the raw, physical tone of classic 4U banana systems. Every patch was shaped through direct voltage interaction rather than digital post-processing, preserving the unpredictable complexity that defines the Serge approach."

About this Pack

It does not simulate acoustic behavior; it generates its own logic of vibration. Each circuit is an experiment in how voltage can behave as if it were alive.

The recordings move fluidly between the precise tension of Eurorack signals and the raw, physical tone of classic 4U banana systems. Every patch was shaped through direct voltage interaction rather than digital post-processing, preserving the unpredictable complexity that defines the Serge approach. 　

Why Serge Matters
Serge Modular was designed in the 1970s by Serge Tcherepnin. It was created as an open-ended tool for sonic experimentation. Influenced by cybernetics and avant-garde composition, this system rejects musical hierarchies and embraces uncertainty.
In Serge, control voltages and audio signals are treated as equals. The circuits invite exploration through feedback, cross-modulation, and unpredictable interactions. Every patch is a process of discovery rather than reproduction.
This makes Serge a powerful choice for artists seeking sounds that are not pre-shaped or confined by rules. The textures you will find in this pack are unstable, alive, and deeply human. 　

Inside the Pack
The collection includes loops, one-shots, and drones. It extends from tonal minimalism to complex, evolving noise structures. You will find FM and AM modulations, unstable oscillations, and dark ambient layers that drift beyond equal temperament. There are moments of feedback that verge on collapse, SSG circuits running into chaotic self-modulation, and subtle rhythmic patterns that carry the unmistakable texture of analog uncertainty.
Each sound maintains the distinctive grain of Serge synthesis: harmonic richness without symmetry, motion that arises from interaction rather than programming. This is material for artists who value the tactile quality of electricity, who hear circuits as compositional partners rather than instruments. 　

Who This Pack Is For
Ideal for producers working in experimental electronic music, sound design, ambient, noise, or techno.
This pack suits those who are not satisfied with polished libraries and are looking for materials that add edge, texture, and risk to their work. 　

Continuous Evolution
This library is a growing archive. New sounds are added through regular updates at no additional cost for existing users. If you already own the pack, simply log in to your Sellfy account and new files will appear automatically. For those new to the collection, this is an invitation to enter a sonic environment that is never fixed but always evolving. 　

Not Just a Sample Pack
Some of the included tracks were originally composed as complete works. These can be experienced as finished drone pieces or used as inspiring source material. The lines between sample and sound art are intentionally blurred."
