You can find demos of the Noodlebox in previous posts here.

"Tested in great working condition, super fun sequencer! Includes AC power supply.

Noodlebox is a four part sequencer for making electronic music. It has analog CV/Gate outputs for each part and supports MIDI.

There are independent sequencer layers, each with a CV/Gate output. Each layer runs separately to the others (although staying in sync) and has its own step count, clock division etc.

Each layer has four pages of up to 32 steps each. Pages can be used for A/B/C/D type pattern variations, for verse/chorus type song sections or chained to make a single pattern of up to 128 steps. You can cue up lists of pages for automatic cycling (up to 32 pages). Arranging pages is designed to be quick and easy to do creatively in a live setting.

1985 Sequential Circuits TOM 4-Voice Drum Machine

Additional SYNTH CITY Listings

"Fantastic working unit, fully serviced by our in-house technician. Recapped, all buttons cleaned and rebuilt external power supply. Fully functional.

In 1985, the TOM was a really advanced drum machine, fully programmable and featuring digitally recorded drum sounds. It is similar to the DrumTraks, but much more advanced. Its sound fidelity is very electronic and it offers just eight of the most basic drum kit sounds. However, each drum sound has a much more flexible tune control than any other drum machine of its time, allowing you to change cymbals into gongs, for example. All sounds can also be layered, allowing for chord-like drum tones, tom rolls and all kinds of wacky sounds. You can also play its sounds in reverse and program the pan position and volume of each sound. Sounds on EPROM cartridges can add up to eight additional drum tones for different sounds. This machine is also MIDI equipped, able to transmit and receive all of its controller information including volume and tuning."

Studio Electronics MIDIMOOG w/ Original MiniMoog OSC Board SN 1123

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

via this auction

Pics of the inside below.

"Original model MidiMoog.. Not very many of these made. This was one of SE's first builds. These few MidiMoog's had an original vintage Moog MiniMoog OSC board.. this is one of those.

It all works great.. Thesis Audio completely went through it a couple of years ago.. It is working and sounding great.. just like a vintage minimoog!

In many ways its better than a vintage minimoog.. it has MIDI, it has LFO and Filter Aftertouch!!! And is very portable.. all with the Mini sound.

A couple of things to note. There are scuffs and scratches around the body, The first WAVEFORM knob is a little loose from its post.. NOT THE POT.. just the plastic knob over the metal pot post.. needs a new set screw. And.. while its perfectly scaled and in tune across many octaves.. you may have to scale and tune it after transit.. takes 5-10 min and super easy.. tuning / scaling pots are accessed via the back panel with a mini flat head screwdriver. Might not need tuning when you get it, just stating for full disclosure."

Behringer Cat Retro & Modern Patches: Bass, Lead. No Talk Demo

video upload by Anton Anru

"Welcome to the soundset for the Behringer Cat synthesizer.
«Analog Classics» is a collection of 60 patches: 18 Leads, 16 Basses, 16 Plucks, 5 Chords, 5 FX.
It includes famous sounds that are found in many electronic tracks, from vintage to modern, musical solo timbres; retro basses that will fit into any track or performance. The patches will add uniqueness to your music, featuring the characteristic sound introduced by the Behringer Cat.

📦 Get the soundset:

Plucks are excellent for use with arpeggiators or sequencers. In most examples of this category, I utilize an arpeggiator. Behringer Cat doesn’t have a built in arp/seq, but you may integrate your preferred arpeggiators or sequencers from your DAW or MIDI controller.

Chords are patches that involve intervals between the oscillators, such as major/minor thirds and others, creating the illusion of a chord.

The presets are suitable for a variety of genres, including: ambient, electronica, IDM, deep, techno, house, progressive, trance, lounge, downtempo, funk, jazz, pop, chill out, new age, cinematic, breaks, jungle, drum and bass, dub and others.

The soundset is presented in the form of PDF-Document. Each page contains notes that explain how the patch works, what parameters are worth tweaking during playback, and how to develop the timbre during a performance.

There are audio examples of all patches inside the folder with the soundset.

Tiptop Audio Officially Releases ART Line of Eurorack Modules

via Tiptop Audio

"Today, we are celebrating the release of the first set of ART-equipped modules, marking the first time this technology is ready for purchase. We are starting with the release of the ATX1 Analog VCO, Vortex Digital OSC, Octopus USB/MIDI interface, ART V/OCT Quantizer, and Control Path dual analog envelopes plus VCA.

On our website, we have dedicated the ART landing page as the knowledge base HQ for ART. There, you will find plenty of educational videos, module video manuals, and uploaded video playlists of music filmed during beta testing. ART is simple to use and easy to understand, and with those videos, we made sure all aspects and potential misinformation have been addressed. Additionally, more information is in the process of being added in the coming days for both DIY enthusiasts and module makers on how to implement ART, including a free reference design that adds ART to Mutable Instruments Braids and Plaits.

The creative process of making music on a modular synthesizer is a unique tactile and aural experience. With ART modules, we are entering the territory of tunable instruments and polyphonic multi-timbral compositions but with the sound design power and immediate interface of a modular synthesizer. The initial release focuses on the mono VCOs that you can use to build voices quickly or combine for discrete polyphony. Very soon, we will extend the lineup with the fully polyphonic ART modules and the release of the Polytip patch cable."

A classic all analog saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analog polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. We consider the ATX1 the best sounding analog VCO we ever created.

Audio Damage Introduces AD057 Axon 3

video upload by ObXession

via Audio Damage

"A drum sequencer that thinks outside the box, where each beat is a live wire, sparking and connecting to create a rhythm that's alive. That's Axon 3 for you - not just an update but a complete overhaul of our legendary Axon series. This isn't your ordinary drum machine; it's a sonic adventure, blending the familiar with the futuristic.

At the heart of Axon 3 lies a sequencer inspired by the complex workings of artificial neural networks. Picture neurons, buzzing with energy, passing triggers in a dance of precision and chaos. When a neuron hits its trigger threshold, it doesn't just respond; it sings, through its internal synth voice, sends a pulse out into the MIDI universe, or both. The connections between these neurons aren't random; they're the building blocks of a rhythm sequencer unlike any. And with a dash of probability magic, we've introduced a drum programming style that's utterly unique.

But that's not all. Each neuron in Axon 3 comes equipped with a powerhouse of a synth voice, drawing on the best of both subtractive and FM synthesis, supercharged with a model inspired by our Boomtschack analog hardware drum module.

Axon 3 wraps all this rhythmic innovation in a sleek interface complete with a full mixer, crystalline delay, punchy compressor, and multiple outputs. Whether you're crafting yout next IDM masterpiece, scoring a film, or just exploring new sonic territories, Axon 3 is your co-pilot in this thrilling journey into sound.

So, are you ready to break the rhythm barrier? Welcome to Axon 3.

• Greatly expanded synthesizer voice, with a full model of our Boomtschack analog drum synthesizer hardware (RIP).

• Pitch and scale quantizing of the internal synthesizer voices, for easier melodic programming.

• Extensive randomizer for changing some or all parameters.

• Cymbal oscillator from Tattoo added to noise section.

• Rough Rider compressor added to master output.

• Likelihood of trigger event and ratcheting added to sequencer, to greatly expand the rhythmic potential.

• Artificial Neural Network sequencer features seven neurons, and is easily programmed to create strange new repeating rhythms.

• Seven FM/VA percussion voices that also buss together to create a single monolithic complex percussion synthesizer, via AM and FM busses.

• Full mixer with pan, level, mute, and solo on each voice.

• Built-in stereo delay, for live playability.

• Built-in Rough Rider compressor on the main outputs.

• MIDI in and out, for driving Axon's voices from DAW and hardware sequencers, or driving other software and hardware from Axon.

• Internal transport for non-synchronized playback.

• Resizable vector-based user interface.

• XML-based cross-platform, human-readable preset system, with copy/paste, for easy transferring of your own presets and third-party offerings."

Moog Minimoog Voyager Signature Edition SN 523

via this auction

"This is an excellent Bob Moog Signature Voyager V3.5 (Serial number 523 of only 600 produced). All synthesizers in this line were inspected and signed by Dr. Moog. Moog offered solid wooden cabinets for this model. Maple, Cherry and Walnut. This one is Cherry Wood. Unlike its cousins this model has full MIDI as well as a complete compliment of control voltage 1/4 inch connections. An accessory port is also part of the in out options. I have used this synth as the main brains of a modular setup as well as an incredibly flexible controller for Omnisphere and Keyscape!! This really is a nice machine and the reason I am selling it is because I have two voyagers. This synth was used in a smoke free studio. Lastly this is one beefy synth! It is extremely well built and weighs in at around 38 pounds. The origional retail price was $3495.00!"

Baby Audio ATOMS -Unusual Physical Modelling Synth - Sonic LAB Review

video upload by sonicstate

"We take a look at the brand new Baby Audio ATOMS - a physical modeling synth based on the Mass-Spring concept.
At a basic level: The specific physical model has been turned into an instrument by Silvin Willemsen and Baby Audio. There are masses (usually balls) connected by springs (virtually of course). These are excited by a bowing action and so the masses move and the springs react.

In its simplest form these are sine waves, but with additional parameters thrown in the algorithm they become more complex.

Weird, yes and sonically pretty pleasing when process by the rest of the ATOMS voice architecture - namely, a filter and a reverberator.

What you'll find are atmospheric, organic and certainly unusual sounds that share a common ground. Its an early release, with a couple of missing things - MIDI mapping for instance, but these we suspect will soon be added.

Available now priced at $59 intro offer from"

Sound Examples - Atoms - Baby Audio

"Synthesis from the other side
Atoms is a new kind of synth plugin that uses cutting edge physical modeling to generate an endless variety of organic and otherworldly sounds. Use it to build rich and alive textures the world hasn’t heard before.

Physical modeling simulates the behavior of real life instruments. But Atoms takes you beyond what’s possible in the natural world. Its features are deep enough to explore the outer bounds of sound design, yet so simple that you can easily mangle, shape and create.

Atoms is powered by a simulation of interconnected masses and springs with tweakable properties and dimensions. The model is triggered by a virtual bowing action that excites the system and makes it vibrate to generate sound.

Nothing in the natural world is ever truly static. Physical modeling mimics this by generating sounds with the same organic fluctuations as acoustic instruments.

Atoms takes it even further. Its six main parameters can be automated with a selection of powerful motion options to add extra life. This lets you create soundscapes that are constantly shifting and re-generating, like a natural organism.

If you’re used to working with sample libraries, Atoms will bring a new level of otherworldly realism into your tracks.

Atoms comes equipped with a powerful randomization engine. It’s a musically calibrated algorithm that selectively adjusts each parameter based on its relationship to the others, giving you usable patches with every roll of the dice.

You can narrow the algorithm further by limiting the random ranges for any knob or locking parameters from changing.

Finally, the Recycle button is a second randomizer that will create new patches similar to the current patch. Once you have a sound you like, click recycle to explore related options.

The bottom panel gives you a range of creative effects to further sculpt your sound. You can also choose between four sonic profiles, each offering a different structure of the mass-spring network simulation.

With the exception of Space (reverb), all effects in the bottom panel are created inside the physical model itself. This gives you a range of unique modulation effects that are an inherent part of the physical model and sound more natural than any separate FX chain ever would."

Arturia Keylab Essential 88 Review & Demo

video upload by Starsky Carr

"Here's the latest in Arturia's Keylab Essential range. It's the 88 key version, and works just like the others, but is BIGGER!!

It's quite hefty for a MIDI controller, but portable considering it's keyboard is 88 keys. There's no aftertouch and its semi-weighted, not hammer action, but comes in at a great price. So if you can live without those extras and you want a full range keyboard it's well worth a look."

"We were asked to beta test a new modification for the Solton Programmer 24 - expanding the drum section from a single kit to 32 vintage drum machines.
It adds the classics like the three Linn Drum machines, the Roland TR-808, TR-909, Roland CR78, Korg Mini Pops 7 as well as lesser known machines like the Elka Drummer One, Elka Drum Star 80, EKO Ritmo 20, Siel MDP40, Wersimatic 24, CRB Computer drums and many more 🤩
The additional 31 drum kits will perform just like the original Solton Programmer 24 drum section.

This is a total game changer for more than the obvious reasons - the Solton Programmer 24 has a sequencer, 8 separate drum volume sliders and 8 audio outputs as well as trigger capabilities for the individual drum sounds. It also sends clock and has Midi in/out/thru so it can be easily incorporated to whatever you got cooking with other machines.

It’s a non-invasive modification and fully reversible - no soldering - no drilling holes anywhere - it's installed by simply removing the four original drums eproms inside and hooking up a small additional board in place of two of them.

The modificationis divided in 4 memory banks of 4 drum kits each - you program the banks to your preference - this way you can quickly switch between the drum kits you use the most - or you can of course toggle through all the 32 drum kits sequentially.
Programming the memory banks is easy and sll the instructions you need are provided on Reverb :

The Solton Programmers drum section can accomodate 13 drum sounds per kit.
Some of the drum machines included featured have considerably less sounds and in those cases Andrea, the inventor and seller of the drum chip, has added more drum sounds in the same realm as the drum machine in question.
Due to the architecture of the Solton Programmer 24 the sample rate is 8 bit PCM 22500 Hz which sounds low but is definitely sufficient to maintain character and punchiness - I think it sounds damn good.
This video was made a few months ago and features a trial version that's now been upgraded - clips and smaller issues sometimes heard in the video have been ironed out and fixed on the version that's available for purchase.

Here's the complete list of featured drum machines

4Fade - Quad VCA Mixer for Eurorack Synthesizer

video upload by NoisyFruitsLab

via NoisyFruitsLab

"4Fade is a quad, stereo, linear VCA mixer around 2164 ICs with pre listening stereo headphone path and expanding features.

It delivers clean sound and clickless mutes around quick and high quality vactrols. Still vactrols deliver a slight fade out when muting.

Each channel has a gain stage with boost for low level signals and the level can be controlled

over common eurorack voltage for further dynamics like sidechaining, or DAW automation (MIDI / USB to CV needed! )

The 45mm channel faders got a LED for indicating the level.

The cue path is pre listening, but before the gain stage. A result of keeping the circuit as clean and small as possible without adding another series of VCAs.

So keep in mind, pre listening with gain down only!

The audio inputs are normalized from L to R for use with mono equipment as well.

The sum of all channels leads into a master volume pot and gets indicated over a 10 digit VU meter display after all.

On the backside are connections for the dual send expander and the 5MX stereo mixer to get additional channels.

Together they form a 9 channel mixer with a flexible send path."

Wine Country Sequential Is Winding Down

This the end of an era. Wine Country Sequential was formed by ex Sequential Circuits employees when the original Sequential Circuits went under. They specialized in servicing and providing parts for vintage Sequential Circuits synths. I actually own a Wine Country "Perfect Prophet-5" myself.

via Wine Country Sequential:

"The Long & Winding Road Ends..Soon

It's been 46 years since musicians experienced the polyphonic sounds of a Prophet-5, and 41 years since the Prophet 600 introduced MIDI to the world. Sequential Circuits Prophets have made significant contributions to music, film, & theatre for decades. Since 1987 keeping the Prophet sound alive has always been the goal of Wine Country Sequential, and it's been a long and interesting ride. The ride is now over, Wine Country Sequential repair services for Sequential Circuits Prophets ended in December 2023. However, Wine Country Sequential remains open for business as the liquidation of original Sequential Circuits parts & manuals in order to help vintage Prophets survive in the decades to come.

Liquidation of Sequential Circuits parts, manuals & archival documentation continues. Original Operation & Technical Manuals, Printed Circuit Boards, custom IC's, sound programs, Diagnostic ROMs and various other parts are available for most Sequential Circuits instruments. Wine Country Sequential will remain open for business in 2024 until the parts are gone.

Visit and for updates reflecting current availability of parts as the liquidation continues.

The Last Restored & Warranted Prophet 600 for sale by Wine Country with a 30 Day Parts & Labor Warranty is currently posted on at

Coming soon to is a Collector's Corner page offering original manuals, memorabilia, brochures, and even complete original engineering fabrication drawing packages for Sequential Circuits Prophets, drum machines, & other synths.

TipTop Audio ART Modules

video upload by Luca Longobardi

"Last series of tests before the imminent commercial release of the Tiptop Audio ART modules.
In this session, of which I recorded a small jam, I configured the system so as to have a good comparison on polyphony tracking.

One of the two ATX1 analog oscillators (bass line) is managed via CV through the ART V/Oct Quantizer, the other analog oscillator and the digital one (Vortex) are instead managed via Midi, all via the Korg Sq-64.
The Roland S-1 is routed in the Morphagene, the Just Friends uses the Mutable Instruments Ripples Resonance to ping it on the melody line entrusted to the digital oscillator and the Pladask Elektrisk Dradd adds some glitchy vibes via its Tape function. TX-6 for delay."
