Simmons SDS-1 EPROM Digital/Analog Drum Synth & Huge EPROM Library (60 EPROMs) SN 005758

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

via this auction

According to the listing, this is the one featured in these videos.

"Includes 60 SDS Drum EPROMs, for use with Simmons SDS-1, SDS-7, SDS-9 drum synths.

Up for auction is a white vintage Simmons SDS-1 EPROM-based electronic drum pad in working condition, including 60 different Simmons EPROMs which are also compatible with Simmons SDS-7, and SDS-9 drum synths.

The EPROMs included with this auction are reproductions of original Simmons EPROM chips, almost all of the chips are original Simmons sounds, and is rare to see such an expansive library of Simmons EPROM chips being offered on eBay. I have posted recordings of all of the chips in this auction being performed by the SDS-1 in the link below.

The Simmons SDS-1 is a single voice drum synth that uses 8k or 16k EPROMs to play back 8-bit drum sounds and effects. The drum synth can be triggered by hitting the drum pad or via an external trigger input. There is a modulation section on the drum synth that allows you to set the pitch and pitch bend direction, then a separate runtime generator allows you to dial in a random pitch generator that can range from subtle to extreme. Please check out my link below to some MP3s I made with the SDS1 drum synth as well as YouTube videos (the SDS-1 in the YouTube video is the same one being auctioned here).

The Simmons SDS EPROM drum pad is confirmed 100% working, ZIF, LED, external trigger, output, and knobs are all functioning properly. All 60 drum sound EPROMs included with this auction have been tested/verified and are also confirmed working. Battery functionality has not been tested, as the battery cover is missing and is often missing on these vintage drum synths.

Admin: Update on Auction Posts

Just a heads up, but I will no longer be saving off auction shots in flickr sets. However, I will continue to put auction posts up. Instead of "images via this auction" where images was a link to the flickr set, posts will now read "images at this auction" with this auction being a link to the auction. You can go to the auction to grab the images yourself if interested.

Why am I doing this? Three reasons.

One, it is beginning to consume much more time than I want it to. I post way more now than I used to (30+ posts a day) and I'd like to get some of my time back.

Two, the images have actually become saturated. How many images of a Juno-106 do we really need? Whenever I scrub an auction, if an image looks familiar (they all are beginning to at this point) I'll check my flickr sets to see if I posted them already. This takes a LOT of time and I'm finding that I'm putting up dupes.

Three, I had a seller contact me who said the images I'm capturing are having an adverse effect. People are accusing the seller of grabbing my images for their auctions when the images I have were most likely from that seller's auction! Yep... I was originally capturing the images for two reasons, one for posterity (it would be cool to look back 20 years from now) and two, so people could verify auction images. If you see a questionable auction, you could check the flickr archive and do some research. Well, it looks like that second reason might have backfired. That seller has asked me to remove all of their auction pics. This is the first time that has happened. People are usually thankfull that I put their auction up, but I can understand. The problem with this is that once the Ebay auction link has expired there is no real way to verify who the images came from. Moving forward I'd have to archive and note each seller. That would not only take way too much time, but some sellers might not want me to do this. In short there is no way to keep everyone happy, so I've opted to stop archiving images for now and continue to put up posts for those that want to see and grab them for themselves.

The downside? Once the auction is gone, the images are gone so they are lost. I am still a bit on the fence because of this. I feel like I'm doing an disservice to everyone. If you have an opinion, feel free to comment.

Site Update: A Note on "Auction" Posts

This is just a heads up, in gear for sale posts, new posts will feature "via this listing" instead of "via this auction". If you search for old gear pics be sure to run two searches on the site, one with "listing" and one with "auction" for posts older than today. The reasoning: when the site first launched in 2005, auctions were king. The messaging stuck to make searching for previous posts easier. Since then fixed price listings have taken over and posting via "this auction" when it's not an actual auction no longer feels right. Via this listing is more accurate as it can be either an auction listing or a fixed price listing. I wish I thought of this back in 2005, but again, back then they were auctions. This post is just for regulars on the site who like searching for old pics. Use "auction" for posts prior to today, and use "listing" for newer posts.

The Auctions label, however, will remain for all posts featuring "via this auction" and "via this listing". Unfortunately labels aren't included in the site's search functionality.

You might have also noticed a new statement on top of all auction/listing posts:

Quintron Drum Buddy


Remember this post on the Drumbuddy going up for auction? It looks like the time has finally come.

images via this auction
"Up for auction is a brand new Quintronics DRUM BUDDY, a one of a kind light activated analog synthesizer / rhythm machine hand crafted by New Orleans musician and inventor Quintron. The basic principal of operation is that there are cadmium sulfide light sensors hidden inside the colored tubes around the rotating black can and as the light holes pass them by, the various oscillator sounds are charged, filtered, bleeped and blooped in a variety of different ways. Each of the 4 oscillators is represented by a different color and each has been designed to complete a total rhythm kit, much the same way that the different elements of an acoustic trap set go together. The Blue pipe is the “kick drum”, the red is the “snare drum”, and the green is the “organ oscillator”. This green oscillator is raw VCO melodic organ tone controlled by “general” and “fine” tuning knobs for playing songs in a whole new way - no chromatic scales on this instrument. The yellow is the “space” or “scratch” oscillator which is plain un-effected, eerie sine wave tone which increases and decreases directly depending on the amount of light that is shed upon it. There is a 10 turn / 10K potentiometer wired to control the spinning can motor speed. This allows the player to precisely beat match DRUM BUDDY rhythms to DJ records, drum machines, railroad crossing signals...whatever. There are also various oscillator filters, on / off switches, and momentary buttons on the top panel and a general volume mixer on the front. There is also a light dimmer on the top panel which is a way to uniformly change the overall sound of all oscillators together. At its core the DRUM BUDDY is a straight up old school analog synth (built from scratch with the finest components) with a VERY unusual activation system which allows the player to create a variety of different fixed rhythms or to “scratch” the different sounds by using the momentary switches and spinning the can by hand. In addition to the sound synthesizing capabilities of the DRUM BUDDY, it is also a signal processor and can filter any instrument THROUGH to produce a strange ethereal bubbling effect onto the original signal. This is called the “WOBBLE FEATURE”. There is a bypass on the top panel for this feature and the best thing about this new 2008 addition is that the wobble feature is a totally separate circuit from the DRUM BUDDY synthesizer sounds so that you can play BOTH at the same time and they will be in perfect rhythmic tandem....the possibilities for new sounds and rhythms are endless. ABOUT THE CABINET: The cabinet was built by New Orleans furniture maker Marvin Hirsch out of 100% virgin pecky cypress. The wood for this particular one came from the original Cypress harvest (sometime between 1880 and 1930) and the tree itself could have been hundreds of years old when it was cut. The pecky dark streaking is quite rare and is the result of a fungus that only effects older cypress trees. This special swampy wood is a living antique and most certainly predates the purchase of Louisiana by the United States in the early 1800s. Only 10 cypress Line Drum Buddies were built and there are no plans to build any more ever. The Drum Buddy up for auction here is serial #1 and was originally intended to belong to Quintron (he decided to keep serial #6 with a strange cracked knot in the back as well as #10 - a green sinker cypress cabinet). All Drum Buddies in the world (less than 50 total and only 10 Cypress-Line) except this one here have found homes. This is it for a long long time....possibly ever. The cabinet is truly one of the most beautiful ever made and very unique. Profffits from this sale will go to the New Orleans Musician’s clinic. Please visit http://www.neworleansmusiciansclinic.org to learn about their tireless effort to provide health care to noninsured New Orleans musicians. This Drum Buddy comes with two different cans - a “TWO STEP” can and a “SLOW RIDE” can as well as a manual, power cord, and a static DRUM BUDDY DUSTER for cleaning the instrument. Also included will be a special kit for instructing how to cut your own cans! You will also receive the original broadcast version DRUM BUDDY INFOMERCIAL on Vhs tape and a rare signed test pressing of the original DRUM BUDDY DEMO lp. We understand that this price is very high for your average musician but please keep in mind that the many duties of this auction are being handled by a third party furniture store in Brooklyn called FRESH KILLS and that part of the auction profffffits will go to the New Orleans Musician’s clinic. Fred and John at FRESH KILLS are old childhood friends of Quintron and are very friendly. Don’t hesitate to stop in and see the Drum Buddy in real life and take a test drive or PLEASE don’t hesitate to email me thru this auction with any questions. SEE DRUM BUDDY DEMO VIDEO.

Roland CMU-800R for Sale

Remember the Roland CMU-800R demoed by James Gallant at this year's Pacific Northwest Synth Meeting? Well, at the meeting James mentioned he purchased one brand new from a school that was going to auction off another one. Well here it is. Note these are extremely hard to find with interface card and software. This one is brand new. If you ever wanted one of these, here is your chance. Note that the proceeds will go to the school, so this is also for a good cause. No title link as there are just these two shots.
Here's a link to the auction.

Details:
"This is the second of two extremely rare units from the same source (described below). There is a very cool blog [Matrixsynth! :)] devoted to synthesizers. You can see videos of the first unit we listed in operation and being demonstrated by the successful bidder at the following link.

Up for auction is an all original (and very very rare) Roland CMU 800R in ABSOUTELY NEW condition. This unit is in original Roland packaging, and has never even been unbagged until now (we opened the shipping bag to take a picture of the back of the unit.) It includes the original box, original manual, Apple interface card, interface cable, power cord, and a copy of the original Apple format 5.25” floppy disc with Apple software. The disk copy was made by the gentleman in the above mentioned video, and is an exact copy of the original software (The disk in the picture is the original disk, not included in this auction.) Several Roland brochures are included as well. The Apple interface card has the original metal foil around it used for ESD protection (we will add a modern ESD bag for the card – but we will leave the metal foil intact.) It appears this is exactly what Roland shipped – Box, manual, cable, interface card, power cord, and the unit itself. The original Styrofoam inserts for the box are missing – we will use bubble wrap to pad the unit.

Special Feature: The winning bidder of the first unit spent a fair amount of time figuring out how to get it to work. He has written a wonderful 1 page document to help guide you through that first power-up. This invaluable “Setup Tips” document is included with this sale! It includes a color photo of how to orient pin 1 on the interface cable – a very valuable piece of information.

The winner of the first auction has suggested I include a couple additional interesting facts about these units:

First, they require an Apple II e with at least one floppy disk drive to operate. These are available on Ebay for reasonable prices.

Second, all the eight channels of control voltage and gate outputs on the back of the 800R can be used to control both vintage and modern analog synthesizers that work on the 1V/octave standard. That's pretty much every analog synth out there except for those by Korg and Yamaha.

A history of these units can be found at: link

Scroll on down a little over half way at the above link, or search for the heading “Milestone: The Roland DG CMU 800R CompuMusic”. This unit is a piece of history. Well, maybe a small one. The Sound on Sound page says it all. These were way way ahead of their time, and almost none remain in operating condition.

This unit was donated to a local school decades ago, and sat untouched for years. Unfortunately the original Roland box has “Sound Mixer” written on it in black felt pen by confused band director. To the best of our knowledge, this unit is exactly what was shipped from Roland. We have no way to test it, so it is sold as is, with our belief that it is exactly as shipped by Roland in its day, a couple decades ago. Check out the matrixsynth link for details on how the first unit ran.

All proceeds from this auction will be donated to the local public school instrumental music program. Bid with the assurance you’re helping a small town music program!"

Again, here's a link to the auction.

Update: Note that this seller has been known to sell the software.

Apple II alphaSyntauri Music System

images via this auction


"Apple ][
Alpha Syntauri
Mountain Computer Music System

Complete Apple //e based setup
Fully working, with lightpen, monitor, disk drive, manuals

This auction is a genuinely rare chance (I hate the phrase, but I haven't seen one of these on auction for a year at least) to obtain a Mountain Computer Music System based AlphaSyntauri. This is a digital synthesizer and sequencer package dating from 1979-1982 in terms of hardware - they went out of production in 1985 or so. It is very similar to the Passport Soundchaser system. The complete setup consists of:

AlphaSyntauri "Pratt & Reed" based 61-key velocity sensitive keyboard, which I have rebuilt and cleaned with new bushes. It would benefit from replacement of the foam damper strip along the base below the keys which has disintegrated with age, but this is largely a cosmetic component. This is the same key mechanism used by many classic synthesizers. There is also an interface card for the keyboard.

AlphaSyntauri's preferred bundle of the "Mountain Computer Music System" voice cards - 8-voice (technically 16 oscillators) stereo sound generator and interface board with lightpen, with wavetable synthesis. This has the original box, in poor condition, and manual (no original disks). The system was also available with three-voice square wave cards from A.L.F, which are very limited.


An Apple //e unenhanced system. To be chronologically correct, this should have a ][+ or //e, this is the nearest I can get to a ][+. Enhanced //e models have timing issues. This is equipped with a duodisk disk drive and interface card, and a Philips monitor of suitable persistence for the lightpen to work. It is also equipped with a higher-output, better cooled AE PSU which should make it rather more reliable despite being 25 years old. In the picture, an 80 column card is visible - this is included in the auction but will not be fitted, as it appears to cause minor timing issues with the synthesizer (I added it to the system to include with the auction then remembered why I removed it!).

Software, including the B3 wavetable generator. This is quite complicated to use, but the results are impressive. To be fully useful, the software needs Apple II paddle controllers - either the later, 9-pin D-sub connector type or earlier ones that connect internally. I no longer have a set of these, but will attempt to locate some before the auction ends. They sell for a few bucks on eBay US when they come up.

It's hard to really fully explain how main "MetaTrak" system works, but it features a sixteen track sequencer, is multi-timbral, and quite flexible. By 1979 standards, it was absolutely stunning. Rather than try and explain what it sounds like, here's a link to a recording of a demo track provided with the system called Galaxy Gap [player above] - this has been played back directly from the system for sale, recorded by myself. It is not multitracked or processed in any way. During playback, the notes are represented on screen in a similar style to the panels on "Close Encounters" - when using other software modules, they are bar-graphs showing velocity.

You can play live over an existing track in MetaTrak. Other software has different features; documentation for the Mountain Computer Music System is included but I had to dig around the internet to find out how to use a lot"

Lupine Systems First Vintage DIY Analog Synthesizer For Sale

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

via this auction

Here's an interesting bit of DIY synthesizer history. The only other post to mention Lupine Systems went up last October here. Below are the details from the auction including a link to an audio demo. Note there is a Lupine Systems website still online.

Details via the auction:

Hello DIY synthesizer fans! Way back in the 1970's I designed a number of synthesizer systems. Many of them were basic but for the time they were quite impressive.

I used to build small devices while in school to impress my friends. I often gave away copies of the diagrams, many of which I have seen online in one form or another -- many are very simple in nature and have survived the many years. This design is a hybrid -- the keyboard is digitally scanned but the audio is generated by analog circuits. This combo allows for the use of a matrixed keyboard. The heart of the system is the M50240 Top Octave Generator chip for which the output is divided down to lower frequencies and blended to form the sound to be processed by the filters.

Up for auction is a copy of one of my original synthesizers. The original was built using pad-per-hole and point-to-point wiring. I decided a while back to draft a set of printed circuits for this design "just for the heck of it". Up for auction are the results.

The PC board had a few drafting errors which have been professionally corrected with jumpers (a corrected version is now available but not yet up for auction).

All controls are fully functional and since the photos were taken I have added knobs to all of the rotating controls. I have also added a 1/4" phone jack for the audio output mounted on the rear (not shown).

PLEASE NOTE: THE AUCTION IS FOR THE SYNTHESIZER PC BOARD SET, NOT THE KEYBOARD SHOWN. The keyboard IS HOWEVER INCLUDED. The keyboard is CHEAP and is not of high quality so it is being TOSSED IN WITH THE AUCTION to get you started. Note in the photos that one key has been replaced and does not truly match the rest but plays OK. IT IS HIGHLY RECOMMENDED YOU REPLACE THE KEYBOARD WITH A DECENT ONE rather than rely on this toss-in.

Schematics are included with this auction.

Milton Analog Sequencer 6x16 Vintage Style CV/Pulse Kit


via this auction

"Peter Grenader’s Milton Sequencer
aka Cyndustries Milton Sequencer
aka Plan B Model 21 Sequencer

Up for auction is a partially assembled Milton Sequencer. I was Order #5 for this straight from Peter. I was really looking forward to this sequencer to control some modular gear and I almost fully populated the Engine and one Bank board--but then I ran out of time and the project sat for several years. It’s not going to sit anymore—it’s going to get built very soon by your hands!!!

If you haven’t seen the Milton, it is a dream analog sequencer that has highly configurable functionality depending on parts you populate on the boards--it is a great design! This auction includes all parts for the maximum configuration allowed by the Engine board. You may choose to do this maximum configuration or you can build it any way you like. You even get to design its user interface and control panel to be the centerpiece of your analog rack in whatever format you desire. Hopefully you'll make this an art piece! Fun stuff!

For a while Cynthia Webster for Cyndustries Modular Synthesizers company was making these but her module is no longer available. Currently similar (but inferior) pre-configured sequencers are available from Peter's Plan B company in the Module 21 series. Winning this auction you will get your Cynthia/Plan B sequencer you’ve been wanting; and you can configure the functionally well beyond anything offered commercially! This is your chance to get a nearly full parts kit for all 6 bank boards and you can get started right away!

Included in this auction

>>>> 1 Milton Engine Board…this is mostly populated. Has “Cynthia CYN10” and “PCB by Ken Stone “screened on it.
>>>> 6 Milton Bank Boards…one board is mostly populated, the remaining 5 are not populated. (note that in the picture, one pack of 3 boards is opened and each is displayed while the other pack of 3 is still sealed--under the Main Engine PCB).

>>>> 1 Milton 2-sided Original Schematic and electronic documentation. I will provide this hard-copy 11x17 inch 2-sided schematic along with all other electronic documentation I have available on a CDr. Also I have a printed copy of the manual dated June 2003.

>>>> Various Parts to finish the project. Parts include resistors, capacitors, diodes, ICs, transistors, LEDs, switches, pots, knobs (and faceplate mounting washers and nuts; knobs have a "soft" feel--same as Blacet uses; I have blue and gray knobs included!), professionally made ribbon cables connectors (that are used to connect the boards) and various other required parts. There are a few parts that ARE NOT INCLUDED—the stage gate output jacks (because I hadn’t decided banana or 1/8" mini-jack) and power supply (you have to provide 12-15V DC power).

Sequencer Configuration Choices

I was going for the fully-loaded setup. Of course, you can choose your own configuration and if less than mine you will have some spare parts.
My configuration was going to be:

6x 16 step CV banks
6x 16 step Programmable Pulse Bus
6x 16 step Stage Pulse Outs (output jacks not included)
1x 16 LEDs

Now that is one heck of an amazing analog sequencer! I was going to use the pulse outs to trigger drum sounds but you can use them for whatever you wish." via bug.out

SKYSLIP Base via this auction

"This is an auction for a SKYSLIP Base for a Yamaha DX7 Synth.

This is the BASE that the Various ROMS are attached to (using a small screw in this base). It does NOT contain any sounds. I am selling 3 of the ROMS (1, 4 and 5) which contain the sounds (two banks of of 32 programmes each). I thought it best to sell this separately, in case someone's base has broken but they have all the ROMS.

It comes with the original box and instructions.

The base and ROM 1 are the original design, but ROMS 4 and 5 are the newer red-on-black ones. They all work together. They were produced in 1985."

MFB SEQ-01 Drum Sequencer & Eurorack Synthesizer Drum Modules

Note: Auction links are affiliate links for which the site may be compensated.
MFB SEQ-01 Drum Sequencer via this auction

"Complementing MFBs new DRUM-modules, MFB announces SEQ-1. A trigger-sequencer specialized on creating rhythmic patterns.

SEQ-01 allows to build 16 patterns each consisting of up to 32 steps. All patterns can be saved and consist of 12 tracks.

Patterns offer switchable A/B-parts that can also be used as 2-bar-patterns.

Each step of the 12 tracks can be programmed in one out of three accent values.

„Pattern +“ and „Pattern –“ inputs allow switching to adjacent pattern by trigger signals.

Start/stop and tempo (Clock) can be accessed directly on the module but also be controlled through external signals.

Vice versa, the SEQ-1’s clock output and start and stop functions can be used to control other modules.

RESET allows resetting the selected sequence back to step 1.

SEQ-01 is not only useful to control drum and percussive sounds. Modular synthesizers offer lots of options for trigger-based control like sample ?& hold, switches, clock-dividing, sequencers, logic modules, envelopes and more.

An example: while standard S?&H or clock divider modules are usually fed by a linear clock, the SEQ-1 turn this into rhythmic triggering!

And because the SEQ-1 offers 12 trigger outputs you will surely have some spare outputs for special purposes beside triggering your drum-modules."

MFB Drum-04 Bass Drum Eurorack Synthesizer Module via this auction

"The DRUM-04 module is based upon the circuit used in the MFB-503. It offers a tight bass drum that is adjustable over a wide range in both pitch and decay.

Due to the construction of DRUM-04 as a modular component, the bass drum’s sound parameters Attack, Decay, Tune and Pitch can be addressed through CV-signals from envelopes, LFOs sequencers etc.

Attack adds a short impulse to the sound. By mixing this with the main bass drum sound, the result offers added percussiveness.

Decay controls the release length of the sound. The decay can last up to 2 seconds.

Tune sets the bass drum’s basic pitch between approximately 30 Hz and 100 Hz.

Pitch controls the duration of a applied pitch modulation. The depth of this modulation is fixed.

Drive defines the amount of overdrive applied to the bass drum.

Noise adds a variable amount of noise to the sound.

The module accepts different trigger signal types. These signals do not necessarily need to be analogue or digital triggers. You may also use drum pads, piezo-pickups or even dynamic microphones. Use the sensitivity control to adapt for the input signal. Dynamic trigger signals will not only affect the volume but also attack, decay and pitch."

"Analog snare drum module. The circuitry is from the snare drum of MFBs 503 drum computer but it has been modified and extended with CV inputs for controlling parameters.

- Snap is the decy time of the noise that can be up to 2 seconds.
- Decay controls the tonal decay time of the two oscillators that can range up to one second.
- Tune is used to set the general tunig of the snare drum. Frequency range from approx. 100 to 400 Hz.
- Pitch controls the length of the pitch bend, while the modulation depth is fixed.
- with D-Tune you can detune the two oscillators of the snare
- Noise adds a analog noise to the sound to emulate the snare wires

The snare drum module can be triggered with different signals. This doesn´t have to be an analog or digital trigger signal; you can also use drum pads, piezos or dynamic microphones. You can control the input sensitivity with the Sens parameter. When using dynamic triggers, not only the volume will be affected but also snap, decay and pitch!"

MFB Drum-07 HiHat / Cymbol Eurorack Synthesizer Module via this auction

"Analog drum module for creating HiHat (open and closed) and cymbal sounds. The circuitry is based on the hi hat-section of MFB´s 522 but instead of white noise a "metallic" mix of oscillator sounds is used.

Following parameters can be edited: tune (for all three instruments), decay of open hi hat, decay of closed hi hat, decay of cymbal, tone of cymbal.

Additionally the decays of cymbals and the hihats can be controlled by voltages.

All CV inputs have attenuators. The trigger inputs of the thre instruments are equipped with sensitivity controls.

A special feature of the cymbal sound is the Tone-Input which gives you the possibility to use external sounds instead of the internal square wave generators."

MFB Drum-08 Clap Eurorack Synthesizer Module via this auction

"The Drum-08 is MFB´s new module for generating analog clap drum sounds. Due to the two audio output you can use it in stereo, too.

Drum-08´s circuitry is based on the clap of MFB´s own 522 but it has more parameters: Reverb (decay of noise), Claps (number of claps), Space (distance between claps), Decay and basis (stereo width of the signal).

Additionally there are CV inputs for the claps, space and decay parameters. The trigger input has a sensitivity control."

Hartmann NEURON Survival Kit : Motherboard + 250GB HD

via this auction
" This Kit includes :
* One drop in replacement motherboard
* A new pristine Hard Drive breed ! This is your rare chances to get, for this powerful machine, an extended 250GB version of the original Hard Drive.

Original Hard Drives found in the NEURON were usually within the range of 20GB minimum up to 80GB maximum in some occasion. The provided Hard Drive in this auction is resulting of my intensive works to extend the last Linux partition while keeping all the original linux operating system information safe. The resulting Hard Drive is a 250GB unit from Western Digital, well know for it's silent and cool operation.

As a consequence, the available space for all your Models and Sounds comes up to 230GB. Here this noticeable improvement will relatively cost you as much as some 80GB hard drive clones that were sold here on ebay some months ago. Keep in mind that this is more than just a clone : All of the original NEURON hard drive has been analysed in details such as the Boot records (Mater and Extended ones) and allmost of the original partitions in the respect of the original information close to the byte ! Such an evolution could not be affordable using standard tools such as driveimage, partition magic, nor Acronis, but thanks to my own Linux know how.

Consequently, this auction is for you the occasion to provide your NEURON with a large significant space for your creation, models and sounds, but also the occasion to insure of a second 'Life' for your machine ! : NEURON users community has reported some of the original Hartmann motherboards going dead because a batch of bad components described as the 'Capacitors Plague' . It causes (we will see further occurences of this problem in the future, so it may hit your own neuron motherboard also....) a chemical decay of some of the inner PCB layers. A a consequence, I strived until I found out The motherboard type that fits exactly as the original design as well as its respective shape factor. This new motherboard will run exactly as your previous board. This new board may help you in fixing your Neuron if it's currently faulty, or represents a backup for the future. Keep your Ram, your processor, your Fan as they are since all of them will fit with this new board. Hence, No RAM or Processor upgrade of any sort on your side is needed. The provided motherboard in this auction has been tested and validated within the NEURON Synthesizer : It will run exactly as the original motherboard design (which was the Shuttle Spacewalker MV25). BIOS and Jumpers configuration have both been entirely pre-configured.

> It's a 'plug and play' combo , as soon as it reaches your door.

The hardware is provided with some instructions about how to install the motheraboard, what to connect and where, etc. The extended 250GB hard drive comes into your NEURON synthesizer as was your original drive the first day in, with ModelSet v4 , SoundSet v4 and OS 1.5 all installed."

Note on Ebay Auction Links

All Ebay auctions on this site are affiliate links. What are affiliate links? In short paid links. The way it works is Ebay charges you to put an item up for auction. That's how they make money. They keep 100% of that charge if the buyer comes to the auction directly. If a buyer comes to an auction through an affiliate link like the ones on this site, then they give a percentage of that 100% to the owner of the affiliate link. That would be me. I figure if I'm going to put a link up to an auction, why let Ebay keep 100%. They are a big company and they can afford to help support this site. I do all of this on my own free time and I believe sites like this should be free and supported by ads that are useful and relevant. Never buy anything you do not want to. Also, note that the affiliate fee comes out of that 100%, it is not an additional charge, so it does not cost the buyer or seller of the auction more. Why is Ebay willing to do this? Because they figure it will drive more traffic to them. In my case it would probably be the same as I do not put up posts for the sake of the affiliate links. If I did you would see a whole lot more going up. I was actually a bit uncomfortable with the amount I put up so I created MATRIXSYNTH-B to cut the noise down. I only put the most interesting items up here - either the best shots, the rarest and most unique items, or interesting bits of synth history found in the details of auctions - I only put up posts if they merit a post regardless of the source, whether that be Ebay, Flickr, or other. Why am I putting up this note here? Because I do not want to put it up with every single auction post that goes up. I don't think most would appreciate having to read this in every single post. Why not just say it's an affiliate link in the post and be done with it? Because affiliate links mean different things to different people and I want to explain exactly what it is on this site. Note that there is still a bar for MATRIXSYNTH-B. I frequently post auctions people send me on both MATRIXSYNTH and MATRIXSYNTH-B, and I respect anonymity, although on MATRIXSYNTH I will only put auction posts that meet the bar above. If I posted everything on Ebay, you would see everything here go up. Note saving and posting all of this stuff does take a lot of my time, and it doesn't cost you (buyer or seller) anything. I spend 3-6 hours every single day, Monday through Sunday, on the blog. What I do get from Ebay helps with the sanity.

The Sonica - Serge

Title link takes you to one more shot via this auction and this auction.

Details:
"Up for auction is the extremely rare Sonica, built by Frank Eventoff. Only 650 of these were ever produced, making it a highly collectible electronic device. Very few are now known to exist, and listed below is some information I discovered when researching the history behind this unique instrument.

In 1979, the first Sonicas were produced, a collaboration with Larry Heller. There were 650 eventually built, but very few are seen nowadays. Serge Tcherepnin of Serge synthesizers (analog modular) did the oscillator design, and the oscillator inside the Sonica is indeed a Serge oscillator! The bodies have an interesting gourd/phallic shape, and were crafted of carved wood. The neck is incredibly comfortable, and easily fits into the hand, facilitating the sliding action used for playing the Sonica.

Creator Frank Eventoff's neighbor in Silverlake was a modelmaker and carved the bodies - they produced them in runs of 24 at a time.

Donna Summer bought one of the runs of 24 and created a Sonica Orchestra !!! They performed live in Hawaii, with all the musicians in her band equipped with Sonicas at some point in the show!

The body is made from finely hand carved mahogany.

The sound of the Sonica can best be described as somewhere between a sitar and violin. When run through a simple delay, an amazing array of soundscapes are derived. The front panel features a Key/Pitch Knob, and an On/Off Volume Knob. It also features three buttons. " Slider ", which is a tremolo type effect, " Tone ", which is actually a tonal boost, and " Half-Step ", which raises the note an octave. It features a built-in speaker, with an 1/8 inch output to connect to an amplifier or recording device. It runs on one 9-voly battery which is installed by accessing a plate on the backside of the device. This device includes the original carrying case, and original owners manual. The Key/Pitch Knob seems to adjust the key only intermittently. This may be solved by fine tuning the Key Knob, which is explained in detail in the owners manual. All other functions operate perfectly. This device is guaranteed to work upon arrival, but due to the vintage nature of this instrument, it must be sold as is. Winning bidder to submit payment via Paypal, Cashiers Check, or Money Order within 5 business days of auction end, to include $ 20 insured shipping within the continental U.S."

E-mu Drumulator Drum Machine, MIDI, and EPROMS Kits


via this auction

"The Drumulator is a sample based drum machine from circa 1983. The original Drumulator stock sound set was gritty, lo-fi, 12-bit samples of basic drum sounds, which become a classic in many songs of the 80s. The company now known as Digidesign, or Avid (Pro Tools), created sound sets for the E-Mu Drumulator and other sample-based drum machines, called Digidrums Sound Chips. This auction includes 9 Digidrums Drumulator EPROM kits (5 EPROMs in each kit) in addition to the Drumulator stock drum kit, and a custom 808 sound kit from drummob.

The EPROM sockets inside the Drumulator have been outfitted with 5 removable high-quality EPROM ZIFs that allow for easily removing and installing of drum kits.
