"Here is an extremely rare EMS VSC3 "The Putney" Synthesizer, with the accompanying Cricklewood keyboard. Most VCS3's are extremely rare, but this one has the distinction of belonging to Al Kooper, noted guitarist, synthesist, record producer and arranger. This was used on many of his recordings in the 1970's and 1980's, and was restored 3 years ago to its original glory. A full set of replacement pots were purchased from EMS, but the tech who serviced it found that the original pots were still in fine shape, and after cleaning and lubrication, performed as they should. So, this comes with a full set of replacement pots for whenever service needs arise."

EMS VCS 3 The Putney SN 3211

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"This is a rare chance to secure an original VCS3 in excellent condition. This is one of the most iconic and revered synths of all time.

The VCS3 (nicknamed the Putney) is an analog monosynth housed in a distinctive angled wooden case, a truly classic synth. EMS (Electronic Music Studios) was created in England back in 1969. The VCS3 was one of their first synths and it is still a great, unique, funky little unit! Pictured above is the Mark I model. Pictured is another unit with the small wood-cased DK2 voltage-control keyboard required to play the VCS3.

It has three oscillators, and a unique matrix-based patch system. Instead of patch wires, the VCS3 uses a patchbay grid in which the synth components are laid out, and signal routing is accomplished by placing small pins into the appropriate slots. The VCS3 was, in actuality, a modular type synthesizer reduced down to an extremely portable size.

We are often asked whether mods adversely affects the value of a VCS3. Some collector types may view it as sacrilege, but most who buy a VCS-3 to use often value mods highly – many of our customers ask for more, rather than less, modifications. So, in short, in our view the answer is mods often add value/appeal rather than detract. These wonderful synths should be used rather than placed in glass cases. You won't see another VCS3 with as many perfectly integrated mods as this one has."

Erica Synths Syntrx II Review and Demo // Not just for Bleeps, Fizzes and Ambient Soundscapes

video upload by Starsky Carr

"The Erica Synths Syntrx II is one of the most talked-about synthesizers of recent years — but three years on from its release, is it still worth your money? In this in-depth review and demo, I finally get hands-on with this modern spiritual successor to the legendary EMS VCS3 and EMS Synthi, and I want to bust two big myths: it's NOT as complicated as it looks, and it's NOT just a crazy sci-fi sound effects machine.
🎹 What's covered in this video:

-Syntrx II vs the original EMS VCS3 / EMS Synthi — key similarities and differences
-Syntrx II vs Syntrx I — what changed and why
-The 16x16 digital pin matrix explained simply
-Using the Syntrx II as a standard 3-oscillator monosynth
-The trapezoid (looping) envelope in practice
-All-analog signal path walkthrough
-Onboard 3-channel sequencer, DSP reverb and delay, envelope follower
FM, self-oscillation, noise modulation, and filter techniques
-Sample & hold circuit — how to set it up
-The joystick as an LFO / recording modulation source
-MIDI setup tips (offset fix, CC assignments for X and Y axes)
-Patch saving — what it DOES and DOESN'T save, and why it matters
-Honest pros and cons

🎵 Extended drone demo — 5 minutes of the Syntrx II running a single live patch with the trapezoid looping envelope, FM, noise, filter modulation via joystick, and DSP effects. The full version was over 10 minutes — it really is that good.

💷 Price context: Original EMS Synthis now sell for £24,000+. The Syntrx II comes in under £2,000. If you've ever wanted that Synthi sound without selling a kidney, this might be your answer."

Three Phutney EMS clone PCBs, Tuned

Click the auction link on top when you get there for additional listings.

"Set of Three Phutney PCB Cards – EMS VCS3 / Synthi A Clone A set of three fully built Phutney PCB cards for the EMS VCS3 / Synthi A. These are the highly regarded clone boards designed by Derek Revell, widely considered among the most accurate reproductions available for anyone wishing to recreate one of these classic synthesizers, or to replace cards in an original EMS instrument.

The boards were professionally assembled by an experienced audio engineer, using new old stock germanium and silicon transistors to get as close as possible to the character of the original EMS circuitry.

They have been extensively tested and calibrated in my 1975 EMS Synthi AKS. My original intention was to use them to build a VCS3 “Cloney”-style synth, but that project never materialised.

During testing, resistor values were carefully adjusted until the cards performed and sounded indistinguishable from the original EMS circuit boards.

The sale also includes: • Header and PCB solder-in edge connectors to simplify wiring during a build • A set of blue edge connectors with solder tags if you prefer the more traditional “old-school” wiring approach

All three boards are fully populated, tested, and confirmed working. As mentioned, they were bench-tested and run inside a working EMS Synthi AKS, allowing direct comparison with original EMS cards during calibration.

If you are planning to build a vintage EMS-style synthesizer, this is an excellent starting point, as the boards are already assembled, tested, and carefully tuned to match the performance and sound of a 1975 Synthi A / VCS3."

EMS Synthi AKS Mk2, 1975 w/ Docs & 7" Record

Note: links to listings are affiliate links for which the site may be compensated.

via this Vemia listing

Click the auction link on top when you get there for additional listings.

"A superb and highly original EMS Synthi AKS Mk2, manufactured in 1975, in full working order and very nice cosmetic condition as shown in the photos. The aluminium front panel is in excellent shape and fitted with the original vernier dials, which have developed a lovely natural patina with age and use. The Spartanite briefcase is also in very good condition and retains the correct EMS London badge.
This is a genuine, unmodified example that retains its original character and components, something that is becoming increasingly difficult to find. It has clearly been a well-loved and carefully maintained instrument. I have owned it for the past 11 years, but it’s now time for it to move on to someone who will give it the use it deserves.

The Synthi A itself has been recently serviced by a professional vintage synth technician, and the KS sequencer was serviced four months ago by Robin Wood at EMS in Cornwall, ensuring everything is functioning exactly as it should.

Included with the synth: • Extra patch pins • Original Synthi–KS sequencer umbilical cable (excellent condition) • UK mains cable • Two keys for the Spartanite case so it can be locked — a great security feature… after all, no one would think of stealing a locked briefcase synth!

Also included is an excellent collection of original EMS documentation and ephemera, which is becoming increasingly difficult to find with surviving instruments: • Original EMS user manual, bound for protection • EMS 7' 33rpm demonstration record with cover • Original guarantee form (unused — unfortunately the manufacturer’s warranty has now expired!) • Several original EMS leaflets for the Synthi, VCS3 and Synthi 100 & Synthi Hi-Fli • Unused patch cards from 1975, in two different formats • Original 1975 EMS price list • An unbound copy of the Synthi Educational Handbook

Overall this is a beautifully preserved and highly original Synthi AKS Mk2, complete with period accessories and documentation — something that is becoming increasingly rare.

If you are looking for an authentic EMS instrument with real provenance and ready to continue making extraordinary sounds for decades to come, this is a wonderful example. Serial Number: 45104KS"

RING SM Sounds - A Ring Modulator/Sub-bass Generator & CP-3 Mixer for #eurorack

video upload by AJH Synth Official

"Playing around with the RING SM from AJH Synth. This is a hugely useful module, combining a 3-way all-analogue Ring Modulator, a -1 and -2 octave sub-bass generator, and 5-channel Moog CP-3 based mixer.
This is a real ring mod, as opposed to the more common, simpler and cheaper circuits found in many synths, such as the Odyssey, which often used CMOS chips to mimic the same behaviour. The authentic vintage circuit recreated in the RING SM is based on the Ring Mod of the EMS Synthi/VCS3, and has a hugely thick, rich tone.
The Sub Bass generator derives shaped square waves at 1 or 2 octaves below the pitch on an incoming VCO. This shaped squares are slightly curved at the edges, almost a cross between a square and a sine wave, which produces a much better balance of harmonic content and warmth/fatness than the common, purely square or sine sub basses found on most synths and modules, resulting in thicker yet more musical sub-octaves. Additionally, the 'Double' feature can generate an octave above the incoming triangle or sine wave.
The CP-3 mixers saturates as you'd expect from this classic vintage design, with soft clipping, and a boosted gain level on input channel 5."

EMS Universal Sequencer Playlist

video uploads by analogia pl

A few of these have been featured on the site before. You can use the player controls to skip around.

Playlist:

1. EMS Synthi with Universal Sequencer and RSF Kobol #emssynthi #rsfkobol #rolandph830

It’s a tune done on the Synthi and EMS Universal Sequencer with some help from RSF Kobol processed by Roland PH-830 phaser.

2. 2 x EMS Universal Sequencer with Roland MC-202 #emssynthi #emsuniversalsequencer #mc202

Universal Sequencer is playing a sequence on the Synthi and the 202 - that’s why it’s called “universal” as both sequence and real time layers have CV/gate outputs. No effects other than spring reverb on the Synthi.

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

Tracklist:

01 - Buchla 100 and EMS VCS3
02 - Serge Paperface
03 - Modcan A-Series
04 - ARP 2500

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."
