New Uses for Old Circuits

"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

"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."

New Uses for Old Circuits 03: Sources Of Inversion

New Uses for Old Circuits

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

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."

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."

New Uses for Old Circuits 01: Slew Generators as Lowpass Gates

video upload by La Synthèse Humaine

New Uses for Old Circuits

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

In this video we start from the basics and look at the two most famous modules of the Serge system: the Dual Universal Slope Generator (DUSG) and Smooth/Stepped Generator (SSG). These two flavors of slew generator allow us to not only create modulation sources but process audio signals, acting as low level lowpass filters."

Self Playing Patches by BENGE

video upload by Memetune Studio

"This series of studies explores an idea that Benge has been working on over the past year or so, namely that of Cybersynthesis. This involves programming self-contained patches on various modular systems which, once set in motion, will produce dynamic, evolving soundscapes, sometimes purely abstract in nature, at other times veering towards the more melodious

Many different methods were deployed in the patches, depending on the system being used, but normally multiple sequencer and switching devices were combined to give varying degrees of control over long time periods, often without repetition

Other things like random control signals and semi-random events were combined with the sequencers and switching units to bring variation to the performances the machines were making

The key idea at the heart of Cybernetics is the concept of bringing control to chaotic processes. To do this, some kind of feedback loop would ideally be established that can monitor and limit events that might otherwise spin out of control. The Serge and Modcan systems featured here each have various comparator circuits that can, to a certain extent, achieve this highly advanced synthesis feature

In the absence of such sensor paths, it is sometimes possible to use audio or voltage mixers and feedback chains to set various parameters to be on the very edge of chaotic behaviour, an approach used in many of the patches on display here

Other techniques such as the quantisation of voltages and the forcing of notes to play within certain predetermined musical scales were also employed in some of the pieces, which is another way of taming chaotic elements into into a more musical realm

Overall, a wholly experimental approach was applied to the various setups, with the intention of providing an insight into how these machines can behave. Of course, each system has an almost limitless depth to the complexity of patches available, and each track on the album provides just a single snapshot of each instrument used. But hopefully it provides an interesting glimpse into the wonders that these self-playing systems can achieve

Semiqiuncentennial Tension

video upload by Rhythmicons

"An EMS VCS3 does a throbbing drone. The Moog Model 10 is sequenced by a synthesizers dotcom q960/q119 with a little help from the Mos-Lab envelope.

The Serge comprised of licensed circuits by Elby Designs, Catgirl Synth, all lovingly paneled and assembled by Rich at Lower West Side Studios of Canada. There is a Buchla clone of a Source of Uncertainty module assembled and paneled by Jason Fry of Free State FX that is randomizing various parts of an M401 Multimode (Arp 1047 clone) also built by LWSS.
From the 401, the audio heads to the Analog Craftsman Gristleizer. The result is a little rhythmic bubbling.

The title is a nod to Tricky’s Pre-millennium Tension album but nevertheless reflective of the current zeitgeist.

But hey, no sirens this time!

In the meantime I crave my own."

https://akihikomatsumoto.sellfy.store...

About this Pack
This updated sample pack is composed entirely with Serge Modular Synthesizers — systems known not for emulating instruments, but for redefining how sound is shaped.
Included are raw noise textures, slowly morphing drones, and intricate one-shots captured through extensive patching with Random*Source Eurorack modules and classic Paperface 50 series panels.
Each sound reflects the chaotic elegance of analog voltages in motion. You’ll hear modulations that escape grid-bound sequencing, and timbral behaviors that emerge from complex feedback, slewing, and intermodulation — the kind of detail digital systems rarely capture convincingly.
