"Nice condition vintage analogue 'Symphonic Ensemble' polysynth / string synth / organ with excellent control over tremolo, ensemble and vibrato. With three outputs you can send different parts to different effects. The string volume pedal is also very effective at breathing life into sounds. There is a multi-pin output for a rotary speaker - not checked. But everything else was serviced in 2024. As usual, the massive wood-veneer endcheeks are not in perfect condition, but the control surface and keys are very good. Serial number 8632, switchable voltage, currently with a UK plug. These are solid machines: packing 18GBP."

"Pretty good condition considering how old it is - the endcheeks have the usual minor damage on the corners but the panel, knobs, keys etc are very good. It needs a litle work* to be 100%: it has probably about 4 duff keys (will need re-coating with the special compound you can get) otherwise works over CV, Internally from what I remember, it has a slight crack on the pcb which had been patched up and resoldered by the previous owner. Few noisy pots etc."

"Released in 1977, the Yamaha CS30 is the flagship of their CS Monophonic range. It is as close to a modular synthesiser that Yamaha ever made and its modulation and routing options are extensive. This one plays and sounds great. The synthesiser responds to all the pots and sliders as it should and it's ready to use and create weird and wonderful noises and textures. However, to get it to 100 percent functionality the synth requires a service to fix a few issues. Neither the combined 1+2 audio jack nor headphone output work, though the individual 1 and 2 jacks are fine. The sequencer works when switched to Manual and steps through by pushing the red button. However, the 'Clock' function only works when the synth has been powered on for a while and has 'warmed-up'.
Cosmetically the synth is in pretty good shape with nothing broken or missing. There are lots of very small dots of blistered paint, some with a hint of surface rust. The most noticeable ones are at the top of the control panel but these have not increased in size or number over the past decade-or-so. They don't look too bad, in my opinion. Inside is clean and dry with no signs of damp. One of the C keys has a cigarette burn (WHY??!!!) which has melted the plastic slightly. However, all keys are secure and function correctly. The case has a few marks here and there, but overall it looks good.
The case was designed to make servicing very easy. The front control panel is hinged at the back and can be opened by removing just two screws from each side panel. This then reveals a very neat collection of boards and wiring.
The CS30 can be easily integrated into a modern MIDI studio setup. By using an appropriate converter you can interface various features of the synthesiser via its numerous control inputs and outputs:
Foot Controller (CV) for volume in.
Sequencer CV and Trigger (gate) out.
Key Voltage (pitch CV) in and out.
Trigger (gate) in and out.
External (audio to the filter) in.
It features two voltage controlled oscillators (VCOs), two voltage controlled filters (VCFs - both featuring low-pass, band-pass and high-pass options), two voltage controlled amplifiers (VCAs) and three envelope generators. It also sports a ring modulator and a voltage controlled low-frequency oscillator (LFO).
It is fairly unusual for a hard-wired synthesizer in that it features a variety of switches which allow the user to re-route the signal flow from the usual VCO-VCF-VCA convention. For example, VCO 1 can output a square wave through VCF 1 whilst also outputting a high-pass filtered sawtooth wave through VCO 2. Another example is that the envelope generators can be assigned to any of the VCO, VCF and VCA modules and can also be inverted. Because the LFO is voltage controlled, the oscillating speed can be governed by an envelope generator and different waveforms can be applied to the other modules all at the same time. The CS30 also features an external signal input for filtering other musical instruments and audio sources, which can also be used as a modulation source. It includes an onboard eight-step analogue sequencer."

"One of very many items from Calum Hunter's superb home studio - and probably the jewel in the crown. This is a rare black version of Tom Oberheim's classic original Two-Voice synth. Cosmetically it looks a bit tatty at first glance - but on closer inspection, the bad areas where the paint has come off in places are all just on the chassis surrounding the SEMs and sequencer. Oberheim's preparation of these areas was obviously not up to their usual standard. Those pieces are usually white, and they simply over-sprayed them without preparing the surface well enough. In contrast, look at the black section immediately above the keyboard, which is really good.
All the modules (the important bit) are actually in extremely good condition - and apart from the sequencer having four little knob caps missing, near mint.
It would be simple to respray the bad chassis bits if you wanted. The tolex, keys and case hardware are pretty good for their age. There is no lid. The mains socket has been replaced with a safer IEC one. Voltage (TBC) is UK /European.
It has been tested by Audiocircus and is sounding great."
"After a comparison with the TIME-SHIFTER (see the last video) [posted here], let's go back to the TRICOMP alown, this time at audio rate.
The basis for creating a square wave signal is to use a comparator, starting from a sawtooth or triangle wave.
Ok, this is in all synths…
But what can you do with 3 comparators, along with a whole logic circuit connecting them?
...not to mention, if you only get pulses…
In short, a few examples of using the TRICOMP to make PWM a bit richer and more complex than usual.
Thanks to the excellent ROSSUM TRIDENT, which served as my sound source.

"Step back to 1978 and discover the iconic Roland CR-78, the first programmable drum machine that changed the way artists approached rhythm. Before the 808 and modern drum machines, the CR-78 gave musicians the power to create and store their own drum patterns. In the hands of artists like Phil Collins, Peter Gabriel, and Blondie, it became iconic. For this Vault, we’ve preserved the much-loved character of the CR-78 and expanded its sonic potential with some tasteful effects."
The Crow Hill Company creates …RHYTHM MACHINE as latest free VAULTS… VI, preserving vintage classic’s character while expanding its sonic potential
EDINBURGH, UK: The Crow Hill Company is proud to announce availability of VAULTS - RHYTHM MACHINE as its latest VI (Virtual Instrument) release ready for all to download and make music with for free for the rest of their lives — literally preserving Roland’s 1978-vintage CR-78 CompuRhythm’s classic character as the Japanese giant of electronic musical instrument manufacturing’s first programmable drum machine (that changed the way artists approached rhythm and, in doing so, stamped its musical mark on a number of notable hit records that subsequently secured its iconic status in the annals of music technology history for all eternity), effectively expanding its sonic potential with some tasteful effects as a result — as of October 1…
Far from stretching the boundaries of truth, it is fair to say that the introduction of Roland’s CR-78 CompuRhythm changed the course of history as the first computer-controlled programmable drum machine. Most rhythm machines before its late-1978 introduction were preset-only affairs, forcing their users to pick from the likes of ‘Bossa Nova’, ‘Rock’, and ‘Waltz’ — more in keeping with the home organ-orientated terminology of the time. The CR-78, however, offered something new — namely, an ability to program rhythm patterns and store them in memory using the external WS-1 programmer optionally offered by Roland. Indeed, its 14 onboard instruments include bass drum, cymbals, hi-hats, rimshot, snare drum, and tambourine alongside several Latin-type sounds, such as bongos, claves, and cowbell — all generated using analogue circuits, giving it a distinctly warm, punchy character. Thanks to the CR-78’s analogue nature, though, the tempo control is not exactly surgical, but this foible only adds to its charm. And, as history has borne out, when placed in the creative musical hands of Blondie, Phil Collins, Peter Gabriel, and others, it became an iconic instrument in its own right.
"Even though I’ve got dozens of unfinished projects on my trusty Teenage Engineering OP-XY (some of them almost ready) I felt the need to break the cycle. I had the sense I was starting to repeat myself. So I turned to one of my favorite analog synths, the KORG minilogue xd, looking for a patch that could spark something new. And from that came this track… though I’m still not sure what exactly it is.
As usual, the atmosphere is dark, but halfway through it unexpectedly takes on a rock-inspired twist before returning to its original mood. I even tried reworking the idea on the OP-XY to make it more polished (and complex), but in the end I decided to record it raw—exactly as it came to me.
Hope you enjoy it. I plan to explore this same process on other synths as well. Let me know in the comments if this journey through analog synth sound design intrigues you.
🎧 For the full experience headphones are highly recommended.

"The Oberheim DMX is a legendary vintage drum machine known for its punchy, organic 8-bit sampled drum sounds that defined countless hit tracks of the 80s, from New Order to Run-D.M.C. With its iconic swing, individual outputs, and rock-solid build, it delivers the classic analog-meets-digital groove that modern gear can’t replicate.
This DMX is in great condition and includes the factory MIDI and Memory Expansion board. The "Play" button is black instead of the usual white. The DMX includes a flight case that's in good condition.
This DMX was serviced in September 2025 by Synthchaser. Sliders and pushbutton switches were cleaned, and the Synthchaser Battery Eliminator was installed, so songs and sequences are saved without the need for a battery that poses leakage risks and requires periodic changing by a synth tech."
"Well I had an ideas to make famous synthesizer sounds for Hydrasynth and give them away. I’ll drop the link tomorrow, I am falling asleep, as usual it took 5 times longer than I thought to everything done.
I started off with Ben Bohmer and Beyond abeles lead, I though why not to a modern track mixed in with vintage ones.
Then Daft Punk, Europe- the final Countdown, Duran Duran, Axel F Harold Faltemyer and the unison sweep from Rush originally on the OBx I think.
So much nostalgia in these classic synth sound and very happy with the results"

"Monday night I went to a very tiny bar in Lostant IL called the Lost Ant Cafe for fried chicken because the third shift clerk at the Tonica Casey's had a long conversation with Squiche and I about a bunch of stuff on the way back from Knobcon and I asked her what local fried chicken she liked. This was the only place I can remember from the conversation, and it's about a quarter mile down the road from a legendary upper Illinois River valley supper club called The Bull's Head which has been closed for too long. If you don't understand the relationship with the upper Illinois River valley, Italian supper clubs, and fried chicken then I don't know what to say other than you need to touch grass.
I came back to the studio and did this with Lyle. I think it demonstrates how absolutely fried this thing can sound. EBM guys are gonna want to save their pennies for the heaviest (by weight) bass machine they've ever played.
There is a modest amount of distortion on this example, in addition to slow LFOs from each voice controlled by each voice's auxiliary VCAs whose level is set by the Active Attenuators generating a simple voltage offset (something it does if you plug nothing into it) then multiplied to all four voices with the Active Multiples. These LFOs are fed into the second control input of the Vanilla Filters.
Each voice is panned across the soundfield with the output mixer.
In this example I only tweak the gate time on Continuo, global filter frequency and envelope amount, and the amount of the LFO to the filters from the Active Attenuators on the right side of the synthesizer.
As usual with Lyle videos, no effects or mastering at all, simply normalised.
"Hey all, happy to make a jam in honor of Inky da Cat (Lisa Beynon).
She is greatly missed - RIP.
Unfortunately, I had a serious time crunch and had to rush this one out. It was fun, but as usual I had bigger plans for it. I had to upload almost a week early as I'll be away for the InkyFest and deadline just before.
All jams submitted are 10 min or less this time.
Enjoy..."
"The Behringer Syncussion clone is a simple beast. It creates mighty bass drum hits with no effort and has beautiful noise. That in itself is something I find puzzling: If this cheap clone can so easily create big hits why are cheap drum machines always so dinky and gutless?
Here I do some lengthy noodlings with the SY-1 Syncussion with one channel through the Zen delay and the other through the Echolocator. This duo is really growing on me. The Zen has some good grit and saturation, while the Echolocator has various tricks with its freeze, shimmer and filter.
About halfway through I digress into a basic overview of the controls, then it's back to noodling. The DB-01 does a good job with sequencing although the original plan was to drive everything with the LXR-02. But horrors! I discovered that the MIDI out functionality on the LXR-02 is totally broken - confirmed by Erica Synths. Hoping for a fix on that soon. In the meantime the DB-01 will have to battle on as my sequencer.
If there's one thing I could change on the SY-1 it would be to add clock sync to the LFO. For me unsynced LFOs are a huge miss. Otherwise it's an excellent little synth. Two of them mounted in a Eurorack case could easily make for a powerful drum voice solution.
As usual, no DAW processing of any kind, it's all what you see.

MiniBrute 2 has evolved from the legendary monosynth that revolutionized the analog scene with its mixable waveforms, Steiner-Parker filter, and Brute Factor. Now with semi-modular architecture, you can splice its genome and expand its raw power into the world of Eurorack modular. From the earliest electronic instruments, synthesizers have expanded and enhanced the possibilities available to musicians. We decided not only to apply this mantra to the sound of our new instrument, but to synthesizer itself. MiniBrute 2 was born! A synthesizer that would sound huge and yet be compact, self-contained and versatile. An instrument that would be both comprehensive and evolving.
The MiniBrute 2 has nothing to hide. Take a look at its front panel, get yourself acquainted. You’ll notice the now-iconic Brute oscillators, the acidic Steiner-Parker filter, and the mayhem-inducing Brute Factor knob that has become the signature Arturia synth element for many fans.
Looking a bit further, beyond the usual modulation sources and controls, you’ll notice some exciting, unexpected features: a second VCO; a second LFO; new VCO and Filter frequency modulation possibilities; modifier-related modulation destinations; a brand new, loopable AD envelope. Once tamed, this little beast will reveal the full range of its vocalizations, including raging leads and piercing sequences, as well as smooth pads and purring bass."

"Some people might argue that the Elgam Ringo is not exactly an organ, but it was sold as such, though back in 1978 everything that was polyphonic and had a divider based tone generator was generally considered an organ.
(I will probably get mutilated by a mob of angry Polymoog owners now.)
It doesn't have a bass section, which I find quite odd given that it has a drum machine. I would rather have had a bass section. Therefore I am using it together with the mysterious Hohner bass pedals - mysterious because I seem to be the only person in the universe who has this set: Nobody seems to know anything about it.
Because this organ is very basic - five rhythms and four voices - I have made this demo shorter than the others, so there are only 5 songs against the usual 6-8.
The songs are:
Pennies from heaven (John Burke / Arthur Johnston)
Den rige og den fattige (Gustav Winckler / Bent Werther)
Mormors kolonihavehus (Erik Clausen / Leif Sylvester Petersen)
Tanze mit mir in den Morgen (Kurt Hertha / Kurt Göetz)
Wolgalied (Franz Lehar)"
"This demo steps through the patches of the new Vol.2 Factory sound bank for the GND-1T, which can be downloaded from its website. This new bank makes extensive use of the many new features added to the GND-1 since its introduction last year. They are too many to list here, so to find out more please check the GND-1T website: https://richardvanhoesel.com/gnd1t
The demo only has time to play each patch for a short time, but in a more typical / musical context, each patch can be given much more time to develop its full dynamic potential and tonal variations. This bank also includes a few 'keyboard patches' at the top of the bank, which aren't included in this demo.
As usual, everything you hear in these demos is a direct stereo stream recorded from the GND-1T, without any additional processing or effects."
