Model 13700 via this auction
Update via Vedic Scapes: "This Module was not built by me but likely assembled by a customer who bought a kit version."
"Model 13700 Multi-Mode filters from the DIY Buchla module builder known as 'Vedic Scapes'. Clone of a filter design from Belgian synth manufacturer Lassence.
Bouncy, acid-y, self-resonant 24db filter on top and a rich growling 12db filter on the bottom. The bottom has a feedback knob which seems to inject sound between the two filters. Multiple attenuated audio and CV inputs on both.
This module has very solid construction and everything is in great shape.
This is the mk 1 version."

Waldorf Blofeld Synthesizer Desktop Version

via this auction
"Offspring from a noble house - the little synthesizer machine with the big and evil sound.
Waldorf is back in the game. With the Blofeld. This synthesizer offers all the unique qualities that made Waldorf a truly legendary brand.
The engine inside the heavy duty, full metal chassis of the Blofeld delivers the same fat and rich sound that so many Waldorf users worldwide love when they play their Pulse, Q, Q+, Micro Q, Microwave, Microwave II/XT, or even the flagship Wave.
Yes, you've heard it right. The Blofeld is not only capable of producing these warm, organic analog sounds known from the Q synthesizer line, it also sports a wavetable engine like its predecessors with "Wave" in their names.
This unique synthesis system is based upon the revolutionary PPG Wave synthesizers of the early 80s. So when you listen to the Blofeld for the first time, you will instantly recognize those edgy, hard-hitting and bell-like timbres that have been an integral part of so many world hits from the PPG era on, and become increasingly popular once more.
In fact it is amazing to realize that nowadays this complex technology fits into such a slim and elegant device. And for a price no-one would have imagined a couple of years ago.

EAR BUZZ - News from EAR

The first shipments of Model 10's will be delivered and shipped to our dealers Monday. US customers will have them available as early as the day after that. Please leave more time for international shipping to our European dealers.
Major announcement forthcoming on EAR-GROUP.NET
In the next few days Electro-Acoustic Research will announce the first of two new partners into the consortium which will expand it's products and services into an entirely new direction. Keep your browsers here for the official announcement...soon!
Plan B Model 24 Heisenberg Generator progress report
The Model 24 PCBs and faceplates have arrived. Some initial units have been built, but we've determined some slight tweeks required to the firmware. We just felt that your entire system bursting into flames may be a bit too severe for some users. Just kidding - it's only a software interrupt issue, nothing major. Shipments will commence very shortly.
Plan B Model 16 Spectral Multiplexer progress report
The M16 design has been finaliized and with that effort a few new features have been added to what already was a robust set of control options. Go here for details. The board layout process is now in full swing, faceplates are on order and we should be seeing the first of these within a month or so.
Module Statistics added
We have added module statistics (width, maximum current draw) to all released products on the site. They follow directly after the mdule's descriptions.
EAR featured in the Computer Music Journal
The Summer 2006 issue of the prestigious Computer Music Journal features a nice column or two on Electro-Acoustic Research. We'd like to thank our friends Elainie Lillios and Colby Leider for making this happen.
Model 15 ~ a great sine wave just got greater
The Plan B Model 15 Rev. 1.5 boards have arrived. Aside from some minor component placement changes, these new boards have an improved sinewave shaper which reduces the total harmonic distortion by approx. 1/2% (that's one half of one percent). As the photo indicates, the M15 sine has always been real good...but now it's real real good! Instructions for updating your rev. 1.1 to 1.4 boards will be posted in a few days, keep an eye out on this site for updates. For a photo of the resultant waveforms from this change, go here
Model 12 MARK II
The Plan B Model 12 has had a bit of a makeover, adding a Q Low/Q High switch which throws the filter into super high resonance response. It's completely sick, but we think you'll like it Go here All Shipments forom here on in will include the Mark II artwork and functionality.
Model 14 Released
The Model 14 Dual Proocessor has been released at a limited introductionary price of $225 Click here for more info and photos
Model 13 Redux
Like the Model 17, the Dual TImbral Gate has gone through a bit of a facelift with a redesigned board which ellnimates point to point wiring. It's now all done with a single flat cable and the addtion of a second PCB . Go here
New Gallery Section
The homepage was taking too long to load, so we moved our fotos to their very own section. Use the Navbar GALLERY tab to check them out or go here
Plan B Mystery Meat
the following link is a soundbyte of an all-Plan B patch which along with a single Model 10, Model 13 and Model 15, incorporate three new modules you've not seen nor heard before...but you will real real soon One hint: that's NOT a model 12 filter you're hearing. . Go here

Prophet-5 Analogue Renaissance Rev-1 Downgrade
video upload by synthlegends
Additional posts here
"Some tweaking and demonstrating the downgrade mode of analogue renaissance.
What I like in this mod is the boost switch, called Q-compensation and 12 dB Filter, which makes much power even with high resonance in the filter. You can listen it in the first patch in this video. The recording was made without processing, effects and just raw into the audio interface in mono. For further information go on the website of analogue renaissance.
I kept my curtis filter chips, so I can built this prophet everytime back in the original state.
Here is the description from the website of analogue renaissance:
This modification for the Sequential Circuits Prophet-5 reverts the Rev 3 sonically to the earlier, much bigger-sounding Rev 2! The two Prophet 5 versions sound different due to the nearly complete redesign of the voice architecture to use Curtis’ CEM chips instead of Dave Rossum’s SSM chips for the transition of the Rev 2 to the Rev 3 model. This difference in sonics has made the Rev 2’s more desirable - and significantly more expensive. Fully working prototypes have been built and tested, and have the following features:
No mods to the Prophet 5 PCBs are required.
A REV -1 simply plugs into the IC sockets, replacing each CEM3320.
Only 1 extra wire for the -15V supply needs to be soldered.
Electronics have been added that cancel out the pollution from the CEM3320’s level shifting circuitry. The little that remains (30 to 100dB attenuation depending on frequency content and Prophet component tolerances) is also moved entirely to the filter's input. So, it get's further attenuation of 24dB per octave beyond cutoff.
Extras:
The input signal has been increased a bit, since the 2040 likes to be driven a bit harder. This is no issue for the purists as it can be attenuated in the ‘mix’ section of the prophet-5.
By design the SSM2040 is also self-limiting, so the output level has been increased a lot as ample headroom was available, and this gives a much better signal-to-noise ratio and dynamic range.
REV -1 also adds two new features not present in the original Rev 2:
variable Q-compensation that restores the loss of bass when resonance is increased (14dB is lost at the onset of self-oscillation in the original filter design).
the option to use the REV -1 as 2-pole filter instead of the original 4-pole configuration. Most non-linear effects happen in the first two filter stages, and the 2-pole mode lets you hear these effects unfiltered by the last two stages.
The combination of these two extra features will make a Prophet 5 sound absolutely monstrous!
Switches to select 2-pole or 4-pole mode and the amount of Q-compensation will be included with mouting hardware.
Thanks for watching and listening."

Vintage MOOG SIGNAL PROCESSORS
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
See the original advert for the set in this post.
via the seller: "THIS IS A ONCE IN A LIFETIME OPPORTUNITY FOR ANYONE TO OWN ALL THESE UNITS WITHOUT HAVING TO WAIT YEARS & YEARS TO FIND THEM ALL... IT TOOK ME MANY YEARS TO FIND THEM ALL AND SPENT LOTS OF MONEY ON THEM PLUS ALL THE ELECTRONIC MAINTENANCE I HAVE GIVEN TO EACH ONE OF THEM TO HAVE THEM WORK ALL 100%.
I have 5 units in a robust ATA Molded PE Shock w/ Rubber Shock Suspension (12U Space) Model: G-Shock-12L almost new with both front and back lid covers with it's own locking key as well... (REFER TO PHOTOS...) And the Moog Parametric Equalizer as a single unit because it didn't fit in the case unfortunately... But you get all 6 units shipped together as a complete set... NOTE: On the last picture the Bode Frequency Shifter, Bode Vocoder, and the second Moog Parametric EQ ARE NOT included in the bundle they are there just because that's where I had mounted both Parametric EQs but you only get one of the Parametric EQs and not 2 that are pictured there along with the other Bode stuff... Although the Bode Units are going for sale as well but are being sold separately so please refer to info description or ask questions if you're not sure. Thanks...
Here's what's included in the bundle:
- Moog 16 Channel Vocoder 327A - Model: MBVO - X 1 Unit
- Moog Custom Engineering String Filter - ( Fully Calibrated...) - X 1 Unit
- Moog Custom Engineering Dual VCO - ( Fully Calibrated As Well...) - X 1 Unit
- Moog 12 Stage Phaser - Model: MPKH - X 1 Unit
- Moog Three Band Parametric Equalizer 304A - Model: MKPE - X 1 Unit
- Moog Ten Band Graphic Equalizer - Model: MKGE - X 1 Unit
Here's some info you may want to know about each unit:
* Moog Dual VCO - The Moog Dual Voltage Controlled Oscillator was built in very limited quantities by the Moog Custom Engineering Department A.K.A. Modusonic which has 2 Ultra-Stable VCOs based on the 3rd Revision of the Minimoog 921A VCO With Temp Comp UA 726 Matched Differential Pair Transistors. SUPER FREAKING PHAT..!!! Personally I think it beats any Minimoog I've own... The waveforms are just "EARGASMIC"... =) You've got to hear it for yourself... The Moog Dual VCO was designed to add that extra two oscillator fatness to other Moog Synthesizers as the Multimoog, Micromoog and the Minimoog at the time; although the Minimoog required the addition of the Keyboard CV Output Modification so it could control the Moog Dual VCO's pitch and route it's output back into the Minimoog's External Audio Input... The Micromoog & Multimoog did not require this mod because they have already a Keyboard CV Output Jack as well as their respective audio input. So basically you can use the Moog Dual VCO with any Analog Synthesizer with a Keyboard CV Output (1 Volt/Oct.) and an External Audio Input to pass the Dual VCO's output signal back in it and voila two extra fat Moog Oscillators in your set up.
* Functions, Features & Input/Output Option:
- Master Tune - Controls overall tuning of both oscillators or one when only used as single...
- Pulse Width - Controls width of both oscillator's pulse waveforms when used either as single or dual.
- Octave Select Multi-Switch Knob with: LO, 32', 16', 8', 4', 2'. (Both Oscillator 1 & 2 have their own Multi-Switch Knob)

* Moog 16 Channel Vocoder - The Moog 16 Channel Vocoder was designed by Genius Engineer and Pioneer In Electronic Music Instruments Harald Bode in the mid 70's about and first released in about 1977 under the "Bode Sound Company" Brand which was manufactured by Polyfusion under the name of Bode Vocoder 16 Channel Model 7702, and was then licensed to the Moog Synthesizer Brand in about 1978 which was then released as The Moog 16-Channel Vocoder 327A Model MBVO. Both Vocoders are almost identical in circuit design except for a few slight variations in the type of components that were used in each but functions and features are basically the same...

Macbeth Micromac D
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"This Macbeth X-Series Micromac D fully analog synth is in excellent cosmetic condition, it works as it should, no functionality issues. It has seen very light use.
This is a rare synth, was made in the UK out of production, and hard to come by. Built like a tank. Solid enclosure and solid controls. No cheap Chinese plastic components here.
“The fattest vintage sounding desktop analogue synthesizer available.”
Sold with its power adapter for 220v.
A masterpiece by Scottish synth designer genius Ken Macbeth, this is Ken’s take on the classic Minimoog Model D concept of a 3-VCO synth with a 24db ladder filter.
Ken Macbeth is - besides Wowa Cwejman - the best boutique analog synth builder of our time, doing everything the old-school way of through-hole solering. This is true analog!
The sound that his synths deliver is simply out of this world and the Micromac D is no exception. Despite its desktop size it packs a heavy punch. Seriously - in terms of sound this is as good as it gets.
Here are the specs:
3 x 1v/octave tracking voltage controlled oscillators.
Oscillators 1 and 2 featuring 4 waveforms: sawtooth, square, triangle and sine. oscillators 1 and 2 feature pwm control inputs.
Oscillator 3 featuring 6 waveforms: sawtooth, square, triangle, sine, ramp and lower frequency noise.
Oscillator 2 can be hard synchronized to oscillator 1.
Oscillator 3 can be used as a modulation source, both in the audio range and the low frequency range. oscillator 3 can be used to modulate oscillators 1 and 2 as well as the voltage controlled filter. oscillator 3 can be disconnected from the main controlling cv.
Oscillators 1,2 and 3 feature separate control voltage inputs for external control sources.
Oscillators 1,2 and 3 have separate audio outputs (pre-mixer) for external proccessing in other systems.
Oscillators feature separate attenuated volume controls into the filter.
Oscillators 1,2 and 3 feature both course and fine tune frequency controls that have a range above and below the audio spectra.
Noise generator features white noise with its own attenuated volume control into the filter. setting 6 on the oscillator 3 waveform control allows a lower frequency noise to be used for modulation effects and can also be used as audio source.
1v/octave voltage controlled filter:
24db/octave transistor ladder low pass filter. oscillates at high 'q'/resonance.
Tracking of the filter from the main cv input can be 0%/half/full (0v/octave, 1v octave and 1.5v/octave)
The filter also features a separate 1v/octave external cv input for other control sources.
The vcf is swept directly by its own envelope generator.
2 x envelope generators. ads/switchable release type. filter eg can be switch between a positive going envelope or an inverted envelope. filter eg can be switched to sweep oscillator 2 for hard synchronization sweeps. vca eg can be diconnected via an external vca cv input socket.
All analogue circuitry used in the design is the 'old school' through hole parts."

Reon Driftboxes SE, J, and W
REON drift boxパフォーマンス Published on Mar 9, 2016
Note the video above is from March in 2016, so these are not technically new. Reon gear tends to be promoted via Japanese channels. As you can see their website is primarily in Japanese only. They also do a bit of one off and customized gear. Check out the pink one!
Previously featured Reon driftboxes included the driftbox S, S ver II, R, Q, V, E, C, T, and G announced here, back in 2013. There were also modular versions and a Roland branded DriftBox R model announced in 2015. You can find demos and pics via the Reon label here.
BTW, the different spellings and capitalizations I'm using for Driftbox is on purpose. Roland branded it DriftBox with a capital D and B, and Reon interchanges between driftbox, all lowercase, and Driftbox with the capital D. I have also seen it as Drift Box.
That said, not featured here on MATRIXSYNTH before now, are the driftbox SE, J, and W. The following are some details Google translated from Reon.

John Bowen Solaris Test Drive by Carbon111

via Carbon111, via this VSE thread where you will find more images and info.
"I was privileged today to have given John Bowen's Solaris a test drive in my studio! Though its not quite finished yet and there are some re-designs in progress, I can honestly say its a programmer's as well as a player's dream!
It sounds absolutely wonderful and is very powerful! It took a few minutes for the interface to sink in, but once it did...wow! Flexible, deep and yet relatively easy to program due to the excellent UI despite the huge number of available parameters and choices. Most parameters are not buried in menus and are easy to access and tweak.
There are a ton of audio-rate modulations available on this thing, none of which generate any artifacts or aliasing at all...lots of FM possibilities, linear as well as exponential. The Moog-style filter was as warm and squelchy as one could want and could be run in other modes besides LP! The "Obie" clone was a good state-variable emulation. The oscillators were plentfull in both quantity and variety. Each patch has a unique architecture, essentially a massively parallel yet integrated "multi" unto itself.
I was suprised at how organic and non-digital it sounded! A one-on-one "taste test" against my analog gear proved this thing has that elusive low-end "beef". Its no slouch as a complex wavetable synth either, holding its own easily against my Waldorf Microwave XT and Ensoniq Fizmo.
You can do FM, physical modeling, subtractive, wavetable and vector synthesis on it as well as the warmest VA I've yet heard.- I'm really blown away! Time to start saving...or figuring out what will have to go"

Some specs via this thread on the John Bowen Synth Design Forum (BE SURE TO CHECK OUT THE THREAD FOR MORE including clarifications):
"The hardware Solaris has the equivalent of approximately 6 Scope boards (the 14 DSP cards), so 6 x 14 = 84 Scope generation DSPs - but remember, you would have to be running your Scope Project at 96 kHz as well...
We have lots of software to finish, so I can't report exactly as to the polyphony count, but here are some of the other specs:

Q&A on the Acxel II Resynthesizer and the Sogitec 4X

The Sogitex 4X is mentioned in the Q&A below. You can find more info on the Sogitex here. The following is some info from that site: "The Sogitec 4X digital synthesizer at IRCAM during the 1980's, was the direct result of Luciano Berio's demand that live electronic sound ought to consist of at least a 1000 sinewave oscillators (1), in order to be interesting for the composer and the audience alike. It was the last huge hardware, that IRCAM instigated before it turned to the ISPW and subsequently to software solutions in the shape of jMax and Max/MSP. The 4X's eight internal custom-built processors were capable of altogether 200 MIPS (2), which being the equivalent of 1000 sinewaves, 500 filters or 450 second order filters (3). Each processor contained a data-memory, an address-memory, a microprogram-memory and a function-memory. For calculations it used 24 bit fixed point units consisting of a multiplier, a arithmetic and logic unit. It also had 256 internal (programmable) clocks and a large dual buffer for recording and playing. The algorithms were cross developed on DEC en Sun mainframes in Fortran and C. (4&5)."
Q&A on the Acxell II via an anonymous reader:
Q: If i understand well,its posible to acxelize a complex sound source from a pre recorded wav with the soundbuilder then use this resynthezized model in acxelink mode again to be able to control that sound it real time via an external audio input (1 or more?)( each one )

via this auction
"This Synth is in perfect shape. Every controllers, every switches respond perfectly as well as the Q knob. Based on discrete circuits with different filter types, an arpeggiator, very good modulation capabilities, dynamic sound processing and elaborate MIDI control, this synth is definitively a modern synth.
This Omega 2 SC, the most affordable Studio electronics Omega model, can easily compete with a pair of analog mono synth, at a far lower price. Think what you could do with two voices combined into a Multi ? 4 oscillators, 2 sub-oscillators, 2 filter flavors (Moog and Oberheim), modulated by 6 LFOs, 6 enveloppes, ... no other analog synth can rival this synth except another Omega with more voices.
This 2 voices polyphonic synthesizer, 2 parts multitimbral stereo analog synthesizer comes factory-fitted with Moog and Oberheim filters and can be expanded with optional CS80, 2600 and TB303 filter cards. Filters can be added per voice giving you a range of filter flavors, unbeatable in the modern synth production. This Omega offers 128 Multimode patches and 256 Factory Presets.
Impressive pads, brass, organs, leads, basses, and many of the other classic analogue sounds, as well as great abilities to create a wide scope for experimentation and ample opportunity for extreme noises, this synth will dramatically increase your creativity.
And if it's not enough for your creativity, I'll provide you for free, the Theriot and the Cadix patch bank as Sysex files (value $99 each). This 2 patch banks are those coming with bank C and D of the C.O.D.E. 8.
Listen to this juicy Phat Fu demo of the Omega :"

MPC5000 Demo Track

"I am betatesting the new MPC5000, which has a VA synth on board. And a quite good sounding one as well. Did a demosong for it.
SynthSCD.mp3
It has a three voice synth on board with all kinds of filters (some
*very* good sounding ones!), two ADSR's, 2 LFO's, sync, crossmodulation, ringmodulation, noise, etc.
The VCOs have sine, sawtri (really from saw to triangle wave), Pulse, White Noise, Pink Noise, Red Noise and PWM)
Filters: Lowpass, Highpass, Bandpass, BandStop, BandBoost, Model 1, Model 2, Model 3, Vocal 1, Vocal 2 and Vocal 3. Most filters with choosable 1, 2, 4, 6 or 8 poles!
Envelopes are snappy. There is a stereo spread that positions the indivual position of each VCO in the stereofield.
There is great arpeggiator as well, plus you can route the synth through the build in effects (to many to mention, and very nice ones in there as well).
The synth is *completely* controlable with the so called Q link
controllers: 12 buttons, 8 knobs and 4 sliders. The user interface is very cool.
The song is pure MPC, only the drums are samples (also from the MPC).
Regards, Boele"
