"Faithful recreation of the ARP 2600 analogue synthesizer. The Korg reproduction retains all of the ease of use and sound of the original semi-modular legend and adds real improvements for integration in a modern studio, not least MIDI, USB and vastly improved outputs.
Choose between the pre and post lawsuit filters, both retain the unique "ARPness' of the filter tone
This particualry synth has only had the lightest of use in a home studio and really needs to be properly cherished and played.
All original pieces included such as flight cases manuals cables etc.""

via JULIEN*S
"THE FLORIAN SCHNEIDER COLLECTION
Auction to be held at Musician's Hall of Fame & Museum, Nashville, on November 19
An incredible collection of more than 450 artifacts from the life and career of Florian Schneider, co-founder of the pioneer electronic band Kraftwerk."
Pics and videos featuring some of the gear below, and his Lederhosen for good measure (thanks greg!).
Update: the post has been fully updated with all the synth related gear. This may just well be the longest post to be featured on the site. I wanted to capture all the pics for all of the details including notes, scuffs, and of course serial numbers. It's an interesting look into what he used, the condition he keped his gear, in some cases, how he actually used his gear. Note the phonetics on the keys of the Casio CZ-101 and DX-100. Note the Midi Switch Box with a built-in speaker? What's that about? Note the camouflage key strap on the Korg RK-100 Remote Keyboard. Did he pick it out himself or did the keytar just come with it? Note the repeat midi controllers and the MIDI saxaphones. Wind was his primary instrument. You'll find a ton of the acoustic gear he used in the other listings. This is a fascinating insight into both what and how he used his gear.

Rack Mount Sennheiser VSM-201 Vocoder
Starting Bid $5,000
Estimate $20,000 - $40,000 USD
A late 1970s Sennheiser VSM 201 Vocoder with no serial number from the personal studio and collection of Florian Schneider of Kraftwerk (see images). While it’s said that only a few dozen of these Vocoders were produced, a few examples made it into the hands of forward-thinking musical artists including Herbie Hancock, Daft Punk, and of course, Kraftwerk, who used a VSM-201 like this on their albums Man Machine (1978) and Computerworld (1981). The VSM-201 has an intelligible sound that has not yet been bested by modern gear. Includes power cable. This VSM-201 has been removed from its wooden enclosure (which bears the serial number plate) and modified with a metal rack mount casing, presumably for live use. Requires 240v, IEC power cable not included.
Dimensions: 19 x 9 x 9 inches
Category: Kraftwerk, Equipment
Provenance: PROVENANCE From the Estate of Florian Schneider

Synthesizing with Moog | Lesson 3: Vibrations
video upload by Moog Music
"Sound is a phenomenon of vibrations in the air. In this episode, we look at the source of vibrations on the synthesizer – the oscillator. We investigate how to tune the oscillator to a particular note and how to add oscillators together. We also dive into the topics of harmonics, looking at how the shape of oscillation creates distinct tones with different harmonic characteristics.
Written, hosted, filmed, and produced by our team of electronic musical instrument experts, this new seven-part educational video series makes learning the fundamentals of synthesis accessible, engaging, and inspiring for anyone curious about science, music, and how the two worlds converge.

Googlish:
"Kraakdoos (aka Cracklebox) is an experimental electronic musical instrument designed by Michel Waisvisz in the 1970s.
This device allows you to produce sound by completing the circuit with your fingertips — each touch creates a different tone, intensity and character.
This version, revived with VAEMI's modern design, features:
• Transformer-isolated line output,
• Internal speaker and external output option,
• LM709 op-amp based analog circuit,
• 9V battery operation.
All PCB and electronic components of the synthesizer you see in the picture will be provided to you as part of the workshop fee. You just need to come to the lesson without bringing anything with you. We will also provide the necessary materials such as a soldering iron, solder, flux, speaker, battery. If you have done a few soldering jobs before, these lessons may be perfect for you. At the end of the lesson, you will have your assembled synthesizer. At the beginning of the lesson, you will be given all the electronic components and a set of schematics and our synthesizer. Relevant notes will be distributed. After introductory topics such as "What is electricity?", "Basic information about the electronic materials used", and "Reading schematics", we will proceed step by step on the synthesizer, section by section, understanding how each section works. At the end of the lesson, we will all be playing our synthesizers together.
During the workshop, participants will build their own Crackleboxes, learn the electronic structure of the device, and finally take home their own instrument. 🎶

Click the auction link on top when you get there for additional listings.
"In excellent condition and fully functional. Most importantly it has had the essential regulator modification. The instrument has been well looked after, having been kept in a non-smoking and pet-free home studio.
The synth comes with the original user's guide and a suitable UK mains power adapter. If you intend to use it outside the UK you will require a 9VAC 1.3A adapter for your local mains voltage.
Ensoniq's swansong, the FIZMO is an incredibly rare and highly sought-after 48-voice synthesizer which uses 2nd-generation Transwave technology to create very organic sounds unlike any other synth available. The top panel is festooned with realtime controls for many of its features, including the unique and quirky 'F I Z M O' knobs which alter various parameters per patch. It is most revered for its ability to create immense textures and soundscapes, often from just a single note.
For deep diving using a computer, there is a reasonably priced Mac / Windows application available called Fauxmo which is a standalone editor / librarian GUI. It edits the instrument via MIDI in real time."

Synthesizing with Moog | Lesson 1: Listening
video upload by Moog Music
Synthesizing with Moog
"'Synthesizing with Moog' invites you on an enlightening journey that answers a complex question: how exactly do synthesizers work? https://inmusic.to/bdhnff3m
In this first episode we go back into twentieth century history to understand the origins of electronic music, discussing concepts like modular design and voltage control to learn how they combined to make the synthesizer instrument we know and love today. We then pose some questions to try and understand how listening works. How is sound created in the air? What does a speaker do and how does a synthesizer control it? How does the ear work? And finally, how do our brains perceive the sound around us? Listening, after all, is the foundation of any musical practice.

Mother Global Settings Editor for the Moog Grandmother and Matriarch by DIRE Studio
via DIRE Studio
"The proper Grandmother and Matriarch editor has landed.
Mother Global Settings is an intuitive editor for Moog's Grandmother and Matriarch synthesizers. Sporting a 500-series rack inspired control-per-function interface, it's a huge improvement over the quirky global settings editing method of these instruments.
For Mac and iPad.
Supports the creative flow.
Each setting is accessible with two clicks/taps at maximum, allowing you to concentrate on creating your music. Actual values are instantly visible on the screen, which may also prevent a disaster by letting you see output voltage levels. And we have added octave buttons to easily set and check keyboard transposition, as well as a sequence selector override for the Matriarch, letting you quickly switch to any sequence — not just adjacent ones.
Expanded control panel.
Separate items for oscillator frequency ranges on the Matriarch. Fine grained control over MIDI output and local control. Extra glide toggle and arp/seq gate length settings managed by the app. And a panic button in case the synth goes rebel.
Presets.
Save all global settings, as well as our extra settings, into files that you can archive with other project material or share with others. Quickly recall them when needed. And of course you can reset all settings to factory defaults.
Keyboard control.
Keyboard shortcuts for settings affecting synthesizer parameters that you may wish to change during live performance or recording: Gate Length, Swing, FW/BW End Note Repeat, Allow Seq Random Repeat, Delay Seq Change, Pitch Variance, Gated Glide, Legato Glide, Paraphonic Unison, Update Unison on Note-Off, Noise Filter Cutoff, Delay Filter Brightness and Multi Trig.
Equally at home on stage and in the studio.
Direct USB connection for the fastest operation and complete auto-detection — perfect for live performance. 5-pin MIDI support for connecting via MIDI interfaces — and even through MIDI routers — allows you to integrate the app into complex studio setups."

"Serial number 0115 (written in blue Biro pen on the wooden underside of the instrument).
This is one of the first OSCar synthesizers made and it has great provenance. On 26 April 1984, I visited the designer of the instrument, Chris Huggett, at his apartment in Headington, Oxford. He demonstrated the synth and said, “Take it home and, if you like it, send me some money”. So I did … and this is the instrument that is being sold now. I took it back to him a few months later and he fitted the MIDI board.
The instrument has recently been restored by Andrew Jury (Synth Prof). All electrolytic capacitors have been replaced, ribbon cables and headers have been replaced, the battery is new, mains switch has been replaced, keyboard busbar and spring contacts cleaned and polished and much, much more. Consequently, the instrument is in full working order."

Sequential Introduces Fourm: A Four-Voice Analog Synth with Polyphonic Aftertouch
A New Fourm of Expression
San Francisco, CA — September 23, 2025 — Sequential has announced the release of its most affordable, synthesizer to date. Fourm is a compact, 100% analog instrument that redefines expressive electronic performance. With its warm, organic tone, hands-on modulation routing, and a uniquely responsive polyphonic aftertouch keyboard, Fourm is ready to bring your musical ideas to life.
At its core, Fourm delivers four analog voices of genuine Sequential sound, derived from the legendary Prophet-5 — complete with dual oscillators, a classic 4-pole lowpass filter, and envelope curves modeled after the 1978 original. The result is unmistakable Sequential warmth and punch, now with overdriven feedback for a performance-ready edge.
For the first time in 40 years, Sequential has returned to polyphonic aftertouch. The team developed the new Tactive™ slim-keys poly AT keybed to work in concert with Fourm’s analog synthesis engine. Every element was co-designed and precisely calibrated to unlock new levels of expression, enabling a deeper connection to our signature sound that no off-the-shelf keybed could deliver. The result is a more expressive bond between player and instrument, energizing new modes of creativity.
“Wowww holy smokes: this thing sounds and feels amazing,” said Bryn Bliska, (keyboards for Chappell Roan, Maggie Rogers, Jacob Collier). “The polyphonic aftertouch is seriously so fun… Sequential nailed it.”
“We’re so excited to bring this innovative all-analog keyboard into the world,” said David Gibbons, Sequential CEO. “At a price-point that most people expect to pay for a monophonic synth, we think this product will invite legions of musicians who have longed for the magic of polyphonic analog sounds to start their journey of discovery with Sequential.”
Notably inspired by the Pro~One, Fourm’s top-panel modulation matrix puts deep sound design at your fingertips—no menu diving required. Modulation sources and destinations are clearly labeled, connections are made with a button press, and color-coded indicators make even complex routings easy to manage.
With its compact footprint, professional-grade build, and a sound engine rooted in Sequential’s most iconic instruments, Fourm is a powerful new voice in analog synthesis.
About Sequential
Sequential has been at the forefront of synthesizer innovation since 1974, creating instruments that inspire musicians and shape the sound of modern music. With a legacy built on the iconic Prophet synthesizers, Sequential continues to push the boundaries of sound design with cutting-edge technology and exceptional craftsmanship.

Tom Oberheim: The Genius Behind the Greatest Sounding Synthesizers
video upload by Anthony Marinelli Music
"Today, we’re at the home of Tom Oberheim — one of the original pioneers who shaped synthesizers and music history. Tom's legacy includes some of the most groundbreaking innovations: (a stand alone ring modulator, the first commercially available phase shifter pedal (my personal favorite), an early digital sequencer, the Oberheim DS-2, and the SEM the first commercially available polyphonic synthesizer made in 2, 4 and 8 voice models, followed by favorites such as the OB-X, OB-Xa, OB-8, Xpander, Matrix 12, DMX drum machine and more... of course, most importantly he gave us the unmistakable "Oberheim sound" on his entire collection of iconic synthesizers that have inspired compositions and performances on countless records by multiple generations of artists.
Joining me for this special interview is my friend Rob Rosen from Rosen Sound—talented musician and renowned expert in synth restoration and preservation, and someone who's worked closely for a while with Tom to keep Oberheim instruments and ALL vintage synthesizers alive for future generations of musicians.
We’ll also be joined by Marcus Ryle, who's done so much. Marcus began his career working closely with Tom, at Oberheim, was a session musician, designed dozens of affordable and accessible products for Alesis - including the ADAT multitrack recording, Quadraverb digital reverb, and HR-1 drum machine, and later co-founded Line 6 (creating innovative guitar effects and revolutionizing digital modeling technology). His insight into Tom’s innovations—and his own contributions in music history —makes this a rare, deeply meaningful conversation.
Let’s get into it."

Crumar Spirit by Cherry Audio is a meticulously crafted virtual recreation that captures the unique and captivating features of the exceptional analog monosynth from 1983, originally designed by some of the most legendary figures in the synth industry. In collaboration with Crumar, we have reopened a time capsule to revive this Italian cult classic and thoughtfully elevated it with Cherry Audio's signature style.
Spirit is a gateway to sonic experimentation, whether you are after wild, unpredictable timbres or warm, analog tones. It is not a polite instrument. Nor is it clean, safe, or obvious. However, twist a few knobs and it will reward you with some of the most colorful sounds you have ever heard from a virtual analog software synthesizer.
Crumar Spirit includes over 430 sensational presets in 12 categories
Producers will find immediate inspiration in Spirit's extensive preset library, created by a talented sound design team led by veteran sound designer James Terris. And don't miss the Spectres for Spirt Preset Pack (sold separately), featuring an additional 100 additional presets by James Dyson.
A "Little Synth" Designed by Legends
Crumar S.P.A., based in Castelfidardo, Italy, was a notable player in the 1970s musical instrument industry, specializing in home organs, digital pianos, and multi-sound keyboards, and with a significant focus on the U.S. market. Sante Crucianelli, the son of the owner, became the driving force behind Crumar's design and strategies. Crumar became known for its open lab culture, frequently allowing competitors to test instruments, a rare practice for the time. Another key figure during this period was Luciano Jura, a designer, musician, and programmer. Luciano became crucial as Crumar's point of contact with synth pioneer Bob Moog, which led to a collaboration that resulted in the creation of Crumar's Spirit synthesizer.
Although many details have been lost due to the passing of key figures and the closure of Crumar, the development of the Spirit synthesizer in the U.S. is well documented. Key contributors to the project, codenamed "Little Synth," included Moog engineer Jim Scott, Moog clinician and electronic music historian Tom Rhea, and Bob Moog himself. The project likely began around 1980 or 1981, and incorporated elements from earlier projects by Scott and Moog. Rhea played an essential role in defining the Spirit's key features, such as the keyboard scanning setup, panel layout, functional architecture, and technical documentation. The Crumar Spirit went into production and was released in late 1983.

4/8/25 (octaves overlay) SWTPC Psych-Tone + ADR Pan Scan + Eventide H3000B
video upload by Cfpp0
"4/8/25 (octaves overlay) SWTPC Psych-Tone + ADR Pan Scan + Eventide H3000B
Do people still have stereos at home, with two speakers? The SWTPC Psych-Tone synthesizer is running through the ADR Pan Scan, and its stereo outputs are hard-panned on the Mackie Onyx 1640 mixer. The Eventide H3000B is on an auxiliary send, fed by both channels. The Pan Scan rate is close to, but not the same as, the rate of the Psych-Tone sequence, which creates the random feel of the automatic panning. The H3000B delay fills the center of the stereo field. I recorded the same sequence in three videos, each with a different range setting, and they are overlaid here."

RITM-2 Synthesizer (1982) - 1 OSC Clone Moog Prodigy
video upload by LFOstore
"According to information that is actively circulating and being replicated on the Internet, the RITM-2 synthesizer was created in 1982 by Viktor Anatolyevich Nikulin, an engineer at the Kirov Musical Instruments Factory, at the request of a musician friend.
The device was well-received by the company's management, and in 1984, it was put into mass production, which continued for 10 years. During this time, the instrument's design underwent three further improvements. It was the only Soviet synthesizer where all components and controls were housed on a single printed circuit board.
Functionally, it consists of one tone generator, a noise generator, a sound signal mixer (triangle, saw, rectangle, noise), a low-pass filter, two full-format envelope generators (attack, decay, sustain, aftertouch), and a low-frequency modulation generator. It is a portable keyboard instrument weighing approximately 9 kg, housed in a plywood case with a lid.
The front panel had two versions: black and white. The main feature of the instrument, which determined its character, long life, and fame in the professional environment, was its unique and harsh sound.
The production capabilities of the enterprise were quite modest, and only about three thousand instruments were produced over the course of 10 years. RITM-2 was produced exclusively on orders from the administrations of houses and palaces of culture, as well as from leading communist enterprises that had their own musical groups.
During the Soviet period, it was impossible to purchase a rare instrument on the open market, and the RITM-2 was not widely known among musicians who were not affiliated with amateur groups. It was not until after 1993, when the Soviet government's support for amateur music, along with the cultural palaces and the Soviet government itself, ceased to exist, that the RITM-2 synthesizer began to find its way into the hands of professional musicians both in Russia and abroad.
The electronic musical synthesizer Rhythm-2 is a single-voice
keyboard instrument designed for solo, ensemble, orchestral performance of musical works of various genres, as well as for educational purposes and obtaining new sound effects. It can be used both in pop orchestras and at home in conjunction with an amplifier-acoustic device having an input sensitivity of no worse than 0.775. It is possible to use a low-frequency amplifier of a radio receiver, TV, tape recorder. The sound quality of the synthesizer will depend on the quality of the amplifier-acoustic device used.
On the Rhythm-2 synthesizer, it is possible to imitate the sound of classical musical instruments (keyboard, string, reed, percussion) with a certain degree of authenticity and create original sound effects (wind noise, the sound of a passing train, the sound of a sea wave, a shot and the whistle of a bullet).
The synthesizer can be used to play melodies with randomly changing pitch or timbre."
