ARP 2600 Modular Synthesizer SN 26690 & 36710

via this auction

"We meticulously refurbished this 2600 in an attempt to future proof it and to make it better than others you may find. This included the following work:

Replaced all faders and slider caps with brand new ones, so all faders work great, with no crackle at all (our cost for these parts was nearly $500)
Rebuilt power supply in an attempt to greatly extend its life.
Replaced synth section handle with similar one.
Replaced tantalum caps as a preventative measure to greatly extend this units life.
Replaced reverb tank rubber bushings.
Replaced rubber bushings in keyboard.
Cleaned keyboard J-wires and bus bars.
Resoldered feet of all modules.
Replaced Cinch Jones connector.
Replaced 3 4027-1 and 1 4015 submodules with our tech's exact replicas so future repairs will be possible (the originals are sealed and cannot be opened for servicing).
Corrected mistakes made at the factory (a couple connections were never soldered!)
The tolex was a bit chewed up along the edges, so we used a black marker to color the wood where it was showing. Replacing the tolex is possible but we're unfortunately not set up to do that here, so we will leave that decision up to the buyer.
Lengthy burn in test, systematically tested multiple times and working perfectly.
...and more.

This work required a total of 30 hours of skilled labor.

The synth section comes with a lid, though it appears to have come from a later 2600 as the tolex does not match. The keyboard section comes without a lid. Sale includes power cord and new Cinch Jones keyboard connector cable."

"This unit has been fully refurbished and is working perfectly. It was disassembled and cleaned inside and out. A couple minor repairs were performed. The aftertouch has been tested and is working well. We want our items to hopefully continue to work well long into the future, so we paid our tech to do some preventative work in an effort to future-proof this VS. All tact switches were replaced with new ones and work flawlessly, as they seldom do these days. Although the original display was working well, we replaced it with a much better and way brighter brand new one that can easily be seen in the dark. The battery still held the onboard memory, but we replaced it anyway so its next owner shouldn't have to worry about it dying anytime soon. We also reloaded the factory patches. The power capacitors have been replaced, which is something we normally do with synths of this age. This VS is better than most other VS's you'll find and is being sold by perfectionists. One thing we should mention for those as critical as we are is that the data slider wobbles ever so slightly when moved, but there's nothing wrong with it - is in fine working order. This VS should make its next owner very happy. It's a real pleasure to play!"

OBERHEIM OB-X 8 Voice Synthesizer

via this auction, also on Reverb


The stock OBX has poor tuning, so we modify them to improve their tuning and make them playable.

This treatment requires approximately 60 hours of skilled labor, and our pricing naturally reflects this.

This OB is for the discriminating electronic musician who simply wants the best.

This unit is working perfectly and sounds like nothing else."

ROLAND JUPITER-6 Analog Keyboard Synthesizer SN 311707

via this auction, also on Reverb

"Like nearly all the high end vintage analog synths we sell, this item has been METICULOUSLY disassembled, cleaned inside and out, FULLY serviced by professionals who’ve been servicing and selling vintage synths for more than the last 2 decades, and systematically tested multiple times over a long period to ensure it’s working exactly as it should. No BS. No ebay surprises. We’re perfectionists and don’t cut corners. Although this instrument came to us in relatively good shape, we want our items to be better than the rest and invested *many* hours of tech time plus parts costs to fully overhaul this unit so it would be clean, working like new again and as reliable as possible for its next owner. This was a serious investment of time, love, and money, and was definitely worth the effort and is of course reflected in the higher than usual price. If you’re looking for a great sounding example of this model that works just like it should without needing to invest hundreds or thousands of dollars in tech fees and waiting from weeks to years, this one should make you very happy.

DETAILS: we paid our tech for 20 hours of skilled labor to not only fully refurbish this unit but also to future-proof it, so it hopefully wont need any work done to it for a long time. Power supply recapped and rebuilt, all pots replaced with new ones, replaced voice card caps, cleaned inside and out, cleaned key contacts and bus bar, replaced battery and reloaded patches, etc. This is costly work that makes our JP6 much better and more valuable than others you may find. Ebay limits the number of photos to 12. There are more on our website."

360 SYSTEMS SPECTRE Oberheim SEM Based Guitar Synth

via this auction, also on Reverb

"We fully serviced this unit a few years ago and used it occasionally since then. The 360 Systems Spectre is an Oberheim SEM (synthesizer expander module) with a built in guitar interface. The SEM is legendary for its excellent tone, thanks in great part to its sweet multimode filter. We got this unit without a guitar pickup, so it hasn’t been tested with a guitar. We had our tech rewire the transpose A and B jacks so they’re now CV and gate inputs so this unit can be controlled with a Roland or similar type 1 volt per octave synth with CV and gate outputs. Since we don’t have a pickup to test this unit with, we don’t know if the guitar interface section is working, so although we have no reason to believe it’s not working, we cannot guarantee it and are therefore selling it as is. 1 of the latches that holds the case closed is missing but the case still closes ok. There's a new fuse-holder too."

The Datanomics SYNTHI 100

This one is in via MATRIXSYNTH reader, Daniel Araya of Camp303 who also restored the Belgrade SYNTHI 100 featured here.

"I just restored the University of Cuenca Synthi 100!

This is the last S100 ever made, by the company Datanomics that took over EMS in 1979.

They produced this unit in 1981/82 and it was used at Gabinete de Música Electroacústica de Cuenca (G.M.E.) until it was put in storage for many years.

Now, thanks to professors Sylvia Molina Muro and Julio Sanz Vázquez a new G.M.E. is started and the Synthi 100 is restored to be used at the University.

The Synthi had been stored in a good environment and was in a nice state.

This machine is very different from the other S100's, it is completely redesigned internally by Datanomics and is using CEM chips (Curtis Electromusic Specialities) that made it a lot simpler to service because the reduced number of components.

The sequencer and keyboard are based around Z80 microcontrollers and are greatly improved from the old ones. Some components had not aged well so I changed out every power supply capacitor and replaced some broken IC's and went through all modules and functions.

I managed to fix about 97% of it in two days, a small part of the sequencer and some controls are still left for the next visit.

The new studios are modern and spacious and sports an amazing vintage quadrophonic Genelec 1024B sound system that is also being restored as well as some cool vintage outboard effects and various reel to reel tape recorders.

I also discovered an original ad/article for this synth while researching, check this out.

The Commodore Music Maker Deluxe

Published on Dec 10, 2019 MrCaliforniaD

"I made this keyboard out of a broken Commodore machine and a Arturia MiniBrute keybed.

This thing is not a MIDI controller nor a Arduino / Raspberry Pi design. It uses carbon contacts that act as switches and connect directly on the keyboard matrix inside a Commodore 64.

Because of this, it can be used with ANY programs that allow the musician to play notes directly on the C64's keyboard, allowing you to use a wide vierity of original music programs that were compat"

Trovarsi Eurorack Techno Tutorial With Noise Engineering Modules

Published on Dec 10, 2019 Perfect Circuit

"LA-based techno artist Trovarsi recently came by our shop to talk about modular synth techniques. If you're curious about how to make techno with a modular synth, this is a great place to start. In this demo, she shows that even the most modest setups can be powerful musical tools when approached with some fundamental techniques and a healthy dose of experimentation. Learn more here:

Trovarsi uses a 62hp Intellijel Palette case of Noise Engineering modules to create an array of alien percussion, slithering bass lines, and frantic, aggressive leads. By linking several sequencers and modulation sources to a single clock source (the Horologic Solum), she keeps everything moving together. Her only sound sources are a Basimilus Iteritas Alter and a Manis Iteritas—but by deploying some clever patching, she expands these into a complex tapestry of fluid, yet aggressive sound.

Proving you don't need a lot of gear to make compelling sounds, Trovarsi turns this tiny system into a full-fledged, in-your-face groovebox."

New Panoptigon Format Disc – GRAND PIANO

Panoptigon plays SILENT NIGHT Published on Dec 1, 2019 optigandotcom

"SILENT NIGHT recorded on Quilter Labs' PANOPTIGON, featuring the new Panoptigon format disc GRAND PIANO (available now!) as well as the Optigan format DARKSOPHONE and Orchestron format VOCAL CHOIR and SOLO FEMALE VOICE discs. Please see for more information."


Published on Dec 10, 2019 optigandotcom

"Announcing a new disc for PANOPTIGON from Quilter Labs! This is the third disc in the new Panoptigon format, only playable on Panoptigon (

GRAND PIANO expands on the concept of our original Orchestron format Piano disc, in that it takes advantage of the full 60-note keyboard of the Panoptigon format, and also we've arranged more complex rhythmic figures for the individual notes, in 6/8 time. As with all of our discs featuring rhythmically articulated scale tones, GRAND PIANO is best used for playing sustained chords to produce rippling, arpeggiated patterns and textures. It's also great for playing in reverse for even more ambient effects.

GRAND PIANO can only be played on PANOPTIGON, and is NOT compatible with Optigan or Orchestron.

The raw piano recordings used on this disc are open-source samples available here:"

How to use a Raspberry PI as a synthesizer

"How to use a Raspberry PI as a synthesizer. Table of contents below! The Raspberry PI is a popular card-sized computer. In this video, I show how to set up a Raspberry PI V3 as a virtual analog synthesizer with keyboard and knobs for realtime sound tweaking, using standard MIDI controllers and some very minor shell script editing. The result is a battery powered mini synth, creating quite impressive sounds! There's a demo at the start of the video showcasing some sounds I came up with.

The Roland XV-5080 Comes to Roland Cloud

Published on Dec 10, 2019 Roland Cloud

"Released in 2000, the Roland XV-5080 stepped onto the scene, leaving a mighty footprint. Described for years as “Roland's ultimate sound module,” the XV-5080 boasted immense PCM-based multitimbral synthesis power, sophisticated modulation, an array of pro-quality DSP effects, and compatibility with the popular SRX Expansion Board series.

Its fidelity and technological adaptability were unmatched at the time and embraced heavily by composers and producers spanning a wide range of genres.

The rackmount Roland XV-5080 was an undisputed hit.

With over 900 presets in its library, Roland Cloud’s XV-5080 facilitates genre-hopping fluidity. From low-end theory to iconic retro game sounds and symphonic masterpieces, this instrument is limited only by the imagination. The categorical search function makes finding the perfect sonic complement to your workflow effortless."

Roland Juno-106 Analog Synthesizer (1984) Forever Young - Alphaville

Published on Dec 10, 2019 RetroSound

"(c) 2019 vintage synthesizer demo by RetroSound
supported by UVI:

I think each one of us has a soundtrack of life, that is, certain songs that connect with formative situations in life. The first love, a moment when you were very happy or maybe even unhappy lost someone.
The song "Forever Young" by the German synthesizer pop group Alphaville was released in 1984. It was the band's second single. There are songs that shape one in many different ways. This one is in my personal Top5.
In 1989 I was lucky enough to catch an Amiga license album. In the GDR, Western music was hardly to be found. The VEB Amiga Berlin pressed few albums, which were under the counter and if, then only with relations to get. In July 1989, shortly before my 17th birthday, I was able to buy an album on the black market. This moment of happiness.
I wanted to cover the track, as a small tribute to this wonderful song.
In the original they used the Jupiter 8, PPG wave, Logan String Melody 2 and for the solo at the end the Arp Odyssey. I recorded everything with the Juno-106. That is also from the year 1984.;)

all synthesizer sounds: #Roland #Juno-106 Analog #Synthesizer (1984) except the aah sound is from the Emax
drums: E-MU Emax samples
recording: multi-track
fx: reverb and delay"

Looping is one of the most exciting things to do on an iOS device. Musicians, vocalists, noise makers, professionals, beatboxers, and hobbyists alike will be delighted by this new looper app from AudioKit.

Inspired by one of the most popular hardware loopers on the market, the legendary RC-505 Loop Station, L7 brings this power to iOS. Easy to use for beginners. Powerful enough for the stage and studio.

L7’s killer features include “VoiceTune” (inspired by Auto-Tune) and the ability to apply eight different effects to each audio track individually. AudioKit L7 is the first iOS looper to have both input (microphone) and output (performance) effects.

You can turn every-day sounds like humming, whistling, and finger tapping into dreamy musical motifs that sound like they were recorded in a professional studio.

Additionally, L7 is the first iOS looper to have effect triggering, which allows you to automatically trigger multiple effect changes in time with the metronome. With this feature you can create powerful, spontaneous musical moments like bass drops and beat changes.

Users can save their sessions and can even export their creations and use them in a professional digital audio workstation (DAW) on their computer to make full-fledged tracks.

L7 is a premium app, which means that once you’ve bought it, it’s entirely yours. There are no in-app purchases, ads, or subscriptions.

It’s available beginning Dec 10th for an intro price of $3.99

This app has an amazing story. Daniel Kuntz started making apps in high school, inspired and enabled by the AudioKit framework. When Daniel met the founder of AudioKit, Aure Prochazka, earlier this year, they quickly discovered their mutual love of loopers.

'AudioKit people were incredibly welcoming, which was a really big deal. I felt like it legitimized my work. It really encouraged me to keep going. I honestly thought they were out of my league. I did not ever consider that we would develop an app together. It’s like a dream come true.' – Daniel Kuntz

Aure was instantly impressed with Daniel’s drive, design skills, and musicality at such a young age. He enthusiastically wanted to partner with Daniel with the mission of creating the most fun and powerful looper for iOS. They might have done it."
