"Roland SH-2 Analog Synthesizer (1979) w/ Original Gig Bag included for free!
I’m pricing it lower than usual for a quick sale due to an unexpected expense. No issues with the synth — just need to move it quickly.
It’s in good condition, fully functional, and sounds amazing — rich, fat bass and creamy leads that only real analog gear can deliver.
Cosmetically, there are some normal signs of age, but everything works as it should — all keys, sliders, and switches respond perfectly.
The SH-2 is a simple layout, huge sound, and built like a tank."

Rare Folktek Micro Garden - Electro Acoustic Drone Synthesis
Note: links to listings are affiliate links for which the site may be compensated.
via this eBay listing
You can find demos in previous posts here.
"For sale is one of the rarest and most sought after in the Folktek Garden Series, The Micro Garden. It is signed by the developer and artist Arius Blaze. It is in very good cosmetic, and 100% operational condition, with no noisy pots, etc. The Micro Garden will ship to include the Power Supply. Insured shipping is $ 40 within the Continental U.S., and all sales are final. Listed below is some information provided by Folktek.
The Garden is a conceptual sound art work and a phenomenal instrument for extending micro sounds into waves or generating odd sounds based on an acoustic source. The sound very much reflects the aesthetic - an electric garden with waves growing from the sound field they're created from. The sound board and spouts of wire extending from it are picked up with high sensitivity and run through a digital delay with a very warm sound. This delay can be as tight as possible or extend to about one and a half seconds. Every sprig of string has a unique sound and the Garden can be played as a percussion piece or soundscape generator. The feedback can be adjusted to generate long extensions of micro sounds to become waves then captured in long format if desired. There is as much musical potential as there is a potential for strange sounds - bits of waves can be stretched in real time and become distant-relative abstractions of themselves."

100 Oberheim Expander/Matrix12 single FX patches by Arthur Springer
video upload by Really Nice Audio
"So whilst on soak test I came across this crazy bank:
Notes from the .txt
ART SPRINGER STRIKES AGAIN (free)
Reviewed by Mike Metlay
All right, gang, I know what you're expecting in this space, so I'll oblige you and get it over with. Ready? Here goes: "WAHOOLAZUMA! Everybody's favorite twisted puppy is back from the audio torture chamber, and he's brewed up the most brain-slashing package of monstrous elektronoyze EVER! This stuff's great for warping your brain patterns, killing your cat, etc..."
Okay. Happy now? Good, now let's get serious. I heard from Art recently that he didn't get a terribly good response to his first mailing, and that few, if any, XUG members looked him up for his second set of patches
He seemed in a pretty good humor about it, but I couldn't help wondering if my presentation of his patch set didn't scare a lot of people away just by the wording. So, with a new patch set from Art (more diverse than the first two) in hand, I'd like to try again.
One of the most unhealthy trends I see in today's patch-editing software is the patch randomizer, that cute but overused utility that generates random patches at the click of a mouse. Literally thousands of these random patches are being sold by unscrupulous hackers as "original sounds," and a whole new generation of MIDI morons is springing up (pardon the pun) whose idea of "good programming chops" is the ability to tweak a randomly generated sound into something that (almost) works. No program of this type exists yet for the xpander, and I'm glad of it: the lack of computer-generated garbage on the market forces the user community to seek one another for new ideas, rather than some electronic I Ching. We come together in this Group to share ideas and learn from one another and I believe that studying another human being's work beats watching a computer coughing up random numbers. Which brings us to the music of Art Springer.
In my opinion, these patches are important. VERY important. I get so enthused about Art's work because I see in him a reflection of my college days, when I puttered about with ARP and Buchla modular monsters creating sounds for the sheer joy of it, putting together tonalities never before heard on Earth rather than trying to make a realistic shakuhachi. This was, and often still is, the meat and potatoes of electronic music to me. And when I hear Art telling me that people- Xpander users!-are returning his work because it's "too weird," I know something's wrong. The Xpander isn't a sampler or a digital piano. It's not an imitative instrument by nature. It's a powerful, multiply interfaceable modular synthesizer with a great deal of flexibility. Art Springer takes a stance on its use that no other Group member has had the courage to try: using its Power as a CV percussion device to enhance the sounds of his more traditionally oriented synths. (By the way, Lionel and I are big fans of his music ... it's not as inaccessible as you might think, and the odd tonalities make his dance pieces a lot of fun.) This is a new idea to a lot of you, and I don't blame you for being frightened. But it's better to learn from someone whose ideas differ from yours than to convince a computer to feed you something safe. I'd like to suggest something simple to start with: get one of Art's sound sets, trigger your Xpander with your drumbox, and try writing music with these sounds as part of the atmosphere rather than conventional drum noises. Or do something completely different. The important thing is to try to expand (hm) your horizons to something new. These sounds of Art's do take getting used to, but I think you'll learn a lot from them. Trust me."

The sound slowly folds into itself — echoes become layers, layers become memory.
Recorded in one take.
No editing, no overdubs.
In this video I explore FM synthesis on the Tiptop Buchla 258t and 259t, using the 245t sequencer to modulate pitch and rhythm, and the 266t for random voltages. It’s a liAnd two featuring Moog for good measure:
ve patch talk — I build the sound and explain what happens in real time, fit's my first video like, hopefully you will like it.

Recorded live in one take — with external effects, Zoom Ms-70 CDR, Grandmother’s raw sound shaped into a soft, floating atmosphere.
🎛️ Gear used:
• Moog Grandmother (analog synth)
• Internal spring reverb & Zoom Ms70 CDR delay
Hi, this is the first video of VoxModula Archives. VoxModula is an ongoing collection of sonic fragments — recordings where synthesis meets the quiet presence of the surrounding world.
Each piece is an observation of sound as a living material: unstable, imperfect, shaped by voltage and time.
The project does not aim to perform or entertain, but to document the space between intention and accident — where tone becomes memory, and noise becomes evidence of existence.
These works are presented without manipulation or spectacle, as if retrieved from an open archive of moments.
Nothing here is fixed.
Everything breathes.
Oberheim OB-8
video upload by Vykaar Tones
"Quick demo of the over sized , great sounding Oberheim OB-8 with the cheap non velocity keyboard implementation that everyone used at the time compared to the sequential T8 that had a great keyboard but didn't sound as good as the prophet 5! I prefer my TEO-5 or the OB6 I had before but I still have the rev4 Prophet 5 desktop."

Computer Creates 2hrs of Ambience
video upload by Saß
"Enjoy the angelic ambient drones of the Destiny+ Programma900. Use the sounds of this synth to meditate and calm yourself, enjoying hours of relaxation and comfort. Let the reverb wash you away as the harmonics take you deeper into soul-searching; who knew mathematics and experimental audio signaling could sound so good. I hope you enjoy this different style of video, let me know in the comments if you do!"

Sonicware ELZ_1 Play | Ambient explorations
video upload by Jay Hosking
"Please support my work on Patreon: / jayhosking
Two ambient pieces composed and performed live on the ELZ_1 Play, with effects.
00:00 - Song 1
04:22 - Song 2
Sonicware sent the ELZ_1 Play over for me to explore because of its big new firmware update. To be honest, there is an overwhelming number of synth engines and effects within the ELZ_1 Play and I only briefly explored the options with any systematicity. Most of the time, I found the synth was a nice device to tweak presets or dial in a sound quickly based on a particular engine type.
A few of the synth engines are quite beautiful and unique, including some tuned noise that it is really pretty. For these explorations, I was mainly drawn to sounds I can't normally make on my other synths, like electric pianos or organs. The options to make and tweak whatever you want are there, but they require you navigating the menus to find them. That aspect works perfect well, but mostly I found the ELZ_1 Play was a great couch device where I noodle.
The biggest and best surprise was definitely the looper, which allows you to have four separate, synchonized or asynchronous loops just spinning away. The looper is an easy way to quickly find inspiration and compose something new.
For these live performances, I've also paired the ELZ_1 Play with a few effects to extend or build the ambient sketch into something a little more complete. The Walrus Qi adds some granular, delay, chorus, and reverb to the finale of the first piece, and the Meris Polymoon adds its phased delay-verb to the second. I also thought I'd try the Soma Cosmos as a different take on the looping idea for the second track.
Overall, I found the ELZ_1 Play to be a good companion for those tired days where all the music-making energy I had was on the couch. Having so many engine types meant I could explore new sounds, and having the asynchronous looper meant I was often quickly in the territory of a full piece.
Thanks for listening.

"This is a unique opportunity to buy a monster synth, that is also a piece of synth pop history. Two cabinets plus the original keyboard, all lids, interconnection cables and original manual included. The first cabinet is a Roland System-700 Lab is one of the rarest and most sought-after modular synthesizers ever built.
Introduced in 1976 as part of Roland’s legendary System-700 series, the Lab version was designed as a compact, self-contained modular laboratory for advanced sound design, research, and education — but with the same discrete analog circuitry, massive sound, and build quality as the full studio system.
This one was owned by Bill Vorn, keyboardist of the synth-pop band Rational Youth, used in the following albums dated 1981 to 1983 : Rational Youth, Saturdays in Silesia, City of Night and I want to see the light, as reported in the certification signed by Bill Vorn himself, provided in the item. The second one is another original SYS 700 one, connected and internally cabled to the main one by means of the original cable, with the super rare modules that you see in the picture: an additional, multimode filter, the great output module and… a professionally custom module with a perfect ARP 2600 VCF clone… plus other stuff.
All the best Sys 700 modules, featuring the iconic vintage Roland tone — warm and incredibly dynamic — and offers an extraordinary range of sonic possibilities thanks to its flexible patch architecture. Perfect for collectors, professional studios, or synth enthusiasts looking for a centerpiece instrument with historical and musical significance. The system sports a comprehensive modular architecture with 3 oscillators, 2 filters, 2 VCAs, 6 envelopes (!), mixer, phaser, spring reverb (HUGE) and …utilities.
Legendary System-700 sound — powerful basses, evolving textures, experimental tones. What to say more? Fully functional and in very good cosmetic condition with minor signs of use. You will never find another in such condition. Last call…"

WaterWork Preview 1
video upload by ParadisoModular
"This video shows a patch that I made over the last month that is all derived from independent water sounds. from I fade the straight audio in occasionally as a stereo pair, but also run it through many effects (e.g., a flanger, granular effects that give it more of a water slap sound, etc.) and fade those in and out too, plus also use the water sounds as triggers (coming from envelope followers) and clocks for lots of audio events, use the water amplitudes to affect various processes, vocode the water against chords, and also run the water sound through one of my frequency/voltage converters that is in turn quantized to a scale that works with the chords, and form different kinds of sequences through that. The water sounds drive essentially everything in this patch. Occasionally I drive my vocoded water sounds through a 'Mellotron' tracker pedal, crossfading the source between the raw and reverbed versions. And so on... - there is lots more going on in this patch. I've evolved it through several versions, tweaking different sounds and processes, and I have hours of this recorded at various stages in case I do something more formal with it. But here's a good 5 minutes of it recorded last week, to give interested folks a flavor of what it does. All autonomous - no real-time input from me - a generative patch essentially driven entirely by the water."
EMS Synthi 100
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.
"This is my EMS 100, serial number 007, clearly licensed to thrill. Arguably, one of the most iconic if not the most iconic modular synth ever built. This is the unit formerly owned by TC media composer Bruno Spoeri. It came to me in a very good state and I enjoyed it for a long time.
I have owned several VCS3s and AKS over the years as well and I would describe the EMS 100 as sounding substantially more organic. It can of course do all the weird and wonderful stuff an EMS synth is known for and take this to extremes. But it also excels at playing it melodically (yes it can do that) which is much helped by the dual manual keyboard which is velocity sensitive (!) and very expressive.
I want the buyer of this wonderful item to be as happy with it as I was. The EMS is therefore currently being refurbished by a world leading specialist with huge experience in servicing and building modular synths and commercial studios all over the world. State of refurbishment The EMS has undergone a complete overhaul. The refurbishment also includes the woodwork and the dual keyboard.
As reported by my tech, the sound generation and the keyboards are fully functional. We haven't managed to fix the sequencer in time for the auction. We also need to fix one of the two spring reverbs. If these two issues haven't been fixed before the auction end I will contribute 5k Euro to the repair as a lump sum reduction of the purchase price. It will be in the buyer's discretion to decide on the further course of action.
Shipping: The EMS 100 main unit is a substantial item. It is currently sitting at my tech's premises. It can be delivered by him with a lorry to most parts of central Europe (within reason). This is to be arranged between the buyer and my tech and will have to be compensated on terms agreed between the buyer and my tech. My tech will also be happy to help setting it up after the journey.
If overseas shipping is required, the EMS main unit can be divided into two parts, the lower pedestal and the console (i.e. the synth itself) which is sitting on the pedestal. Along with the dual manual keyboard this will result in three parts for the shipping. It is no problem to build a crate. This will be have to be arranged by the buyer with my tech.
Important: All shipping arrangements must be made by the buyer with my tech. The ownership of the EMS will pass to the buyer upon receipt of the auction price while the EMS is still sitting at my tech's place. It will be shipped directly from him at the buyers instruction, arrangements and risk. My tech is of course happy to assist with shipping and he has experience with shipping. He has shipped large format consoles over the Atlantic, so he knows what he is doing. As always, the buyer is of course responsible for all import duties and taxes as normal. (Within the EU that is zero!)
Bidding: I kindly ask bidders to only bid with serious intent. Please do not bid if you cannot follow up on your bid. Please keep in mind that the bid constitutes a binding contract and not following up can cause substantial damage to me and/or other bidders. I trust that you understand.
VEMIA note: on reflection, given the pretty remarkable condition of most of the Synthi, we think 'very good' is a more accurate cosmetic score. Please look at the photos to decide for yourself."

I have kept it in a dry healthy environment. It was bought in Europe and I checked it in the US using a European plug and a proper power transformer. The internal loudspeaker doesn’t seem to work. In the video I connected it to an external speaker. Batteries didn’t seem to power up the synth. Not sure why, the connexions are clean. Maybe modern alkaline batteries are weaker than the older ones. This looks like a toy but is actually a very powerful and sought after synth.
TECHNICAL FEATURES
Improved filter: The CS01 II features a 24dB resonant low-pass filter with an adjustable slider for resonance, a significant upgrade from the 12dB filter with a simple on/off resonance switch on the original model.
Sound generation: It includes a voltage-controlled oscillator with selectable waveforms (triangle, saw, square), pulse width modulation, and a white noise option.
Envelopes and LFO: A single ADSR envelope generator controls both the amplifier and filter depth, and a basic LFO can modulate the VCO pitch or filter cutoff.
Portability: Designed for portability, it has a mini-keyboard, a built-in speaker, and can be powered by batteries.
Controls: It includes pitch and modulation wheels, a glissando (portamento) function, and an input for a breath controller.
The CS01 II is a monophonic synthesizer, meaning it can only play one note at a time.
Sound: It is highly regarded by electronic musicians today for its ability to produce "bubbly and growling" bass sounds and other fat analog tones.
Target audience: While its small size and simplicity made it a good beginner's synth when released, its excellent sound quality has made it a valuable instrument for experienced musicians."

How to make the Rush Tom Sawyer synth sound [No Talking] #synth #rush #tomsawyer #oberheim #teo5
video upload by SynthSoniq
"This video is a tutorial on how to make the Rush Tom Sawyer synth intro sound. It's good to know how to create this patch even if you don't want to play Rush, because it teaches you about filter envelopes, resonance, and the general character of a synth's filter. I like making it on any synth because it gives me a feel for that synth's sound. It's then easy to add some attack to the envelope to turn the patch into a great pad, or decrease the decay to make some cool bass sounds."
CS15 w/ Don Solaris mods & Yam Case

Click the auction link on top when you get there for additional listings.
Here’s Yamaha’s classic duophonic (with a little effort) synthesizer with Don Solaris’ mods to facilitate chaining the VCFs for something closer to a 24db/octave response. There’s also a mod to the LFO’s rate control to get better use of it at audio rates - a welcome addition to the CS-15’s already pleasing sound palette. All told, the mods make a good sounding, but somewhat limited instrument rather less limited! It’s in great condition for a synth of this vintage, and was serviced a few years ago by the same techs who performed the mods. The sliders don’t have a “buttery smooth” glide, but are silent, as are the pots. I hear a very, very faint crosstalk between filters while the serial mod is not engaged, and I can’t say whether it’s due to the modification or, as with my old CS30, it’s part of the synth. It’s not noticeable in practical use, but if you’re actively looking for behaviors like this, you might hear it. It’s also like a 50 year old keyboard, so… I would rather have the single-voice CS-30 with its modulation possibilities, but I also just don’t have the space anymore. Please find the details of the mods here: https://greatsynthesizers.com/wp/wp-content/uploads/2019/07/cs-15_mods_DonSolaris.pdf Will ship from Berlin, Germany in its Yamaha-branded hard case.

Pure Filter Satisfaction - The Stylophone CPM DF-8
video upload by Stylophone
"PURE FILTER SATISFACTION CPM DF-8 - Beauty & the Beast of all filters. Release date is 20th Nov - No Pre-order required."
Check with dealers on the right for availability.
"The Beauty is in our smooth, discrete analog recreation of a 2045 (24 dB/oct) LP filter that has been used to great effect by artists such as Massive Attack, Radiohead, and for that distinctive 90s nostalgic filter house sound synonymous with Daft Punk.
The Beast is our proprietary analog GEN R-8 (12 dB/oct) filter that can snarl and howl in all modes (LP, BP, HP, NOTCH).
We then decided to combine the 2045 Lowpass filter with the Highpass of the GEN R-8 to create three additional filter types, a Bandpass (BP+), a phaser-like Band Reject (BR+), and a very wide Notch filter (NOTCH+), for some truly unique filter sounds.
Both filter channels have all eight filter types and are controlled by two full ADSR envelopes with multiple trigger modes to cater for every need. They can be triggered by a gate signal, by an audio signal threshold, by a manual trigger button, and they can even auto-repeat in a loop mode, acting as LFOs.
The release date is the 20th of November. Available from stylophone.com and all good music stores."

Roland SH-3
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing

"A special early synth from Roland in overall great functional condition, with two exceptions note below. Cosmetically the control panel and keyboard area are in nice shape, but the case is pretty beat up, with bad latches, missing metal piping on one side, bent piping on the other side, and a missing power cord door. According to the previous owner, this unit actually went out on tour with a pop band in the 70's, and it shows. As you probably know, the SH-3 gave way to the more common SH-3A, with the most noticeable change being the switch from the SH-3's diode ladder filter to the the SH-3A's transistor ladder filter.
I've thoroughly tested all functions, pots, sliders, and jacks and here are the two functional issues I've observed:
The output and headphone jacks are scratchy and presumably need to be cleaned. It's easy to get an output cable or headphones seated and working, however you may have to twist the plugs in the jacks or reinsert them to get a good contact.
There is some bleed-through from the square/sine LFO that's present in the audio path, most noticeable at quieter volumes or at higher registers. It's not difficult to set up a sound where the bleed-through is either not noticeable or barely noticeable, particularly with everything running loud and with lower waveforms engaged. I have access to another SH-3 that has the same problem (but worse), so I suspect this may be a problem that Roland engineered out of later the SH-3A circuitry, but I can't be sure. Regardless, this is something you may want to attend to at some point should you find it bothersome.
In addition, the 8' "chorus" setting on this and the other SH-3 I've played is noticeably more intense than the SH-3A's I've played, so I suspect this is another feature that Roland tweaked when shifting to the SH-3A circuits.
I recently put $730 into having the synth partially serviced by a noted synth tech, which included:
Fixing an issue whereby the waveform sliders were interacting with each other and significant bleed-through of some waveforms was present.
Cleaning the keyboard and eliminating some squirrely notes and double triggering that had been present.
Replacing some capacitors.
Better securing base of the power cable.
Cleaning a scratchy sider.
So in selling this I'm mostly trying to break-even on those repairs, plus make a little to cover Reverb's fees."
