Emu Emulator III SN 1290697 w/ Extras

via this auction

"Emu Emulator III EIII Vintage 16bit Analog Filter VCA Hard Max Ram Sampler Synth. Condition is Used.Very good condition EIII produced first in 1987-not to be confused with the later and much less coveted EIIIX all digital sampler.This is the very rare 4 space rack unit that typically sells for much higher prices than the keyboard.Comes with 2 manual that are missing some content but a digital manual is available online or I will attempt to burn a disc with some extra files.Also sending along 2 cd-roms produced by Emu Vintage Synths and Special Effects and power cable.The 2gb hard drive already has some of the vintage synth on it along with the operating system 2.40.This is also the 8mb. max ram version.Depeche Mode used this model extensively on 1989s Violator.The Analog Filters and Vca create a superb WARM playback of any content you play through it."

Modified MAM MB33 Analog RETRO Bass Synthesizer w/ Circuitbenders Acid FM Mods

Published on Mar 21, 2017

"MAM MB33 Retro with Acid FM mods: This video shows the filter FM mod modulating the filter cutoff at audio frequencies using the internal square and sawtooth VCO waveforms as FM sources. It also demonstrates the Filter Lock mod that holds the filter and VCA open with no envelope, the resonance boost, and the overdrive mod.

The MB33 retro seems to be designed to slightly distort the output stage at full volume, much like the TB303 did. The Drive mod boosts this distortion savagely for some grungy acid techno sounds."

via the creator Mirco Trentin:

"Two years of hard work, many hours spent for development and many hours for soldering, at the end domilasiezento is alive. Domilasiezento is a dialect Veneto word of 2600. I diced to build it 2 years ago, I'm searching for schematics, pcb, components equivalences, i redraw all pcb's with a CAD but I keep the original layout. Result is DOmilasiezento, Full size, same graphics 3rd generation with 4072 VCF, midi implementation with duophonic cv, case copper with modern tolex and of course a spring reverber.

This is my creature.
have a fun

TM Synthesis FLUX - Temporal Modulation Rhythm Sequencer For Eurorack Launches on Kickstarter

Follow-up to this post. You can find the Kickstarter here.

"Flux is a Temporal Modulation Synthesis™ Complex Rhythm Sequencer for Eurorack.

With Flux, I aimed to create a rhythm sequencer that went beyond quantized rhythms. I wanted the ability to compose true polyrhythms, Euclidean rhythms, realistic and complex rhythms easily. Developing Flux with these goals in mind resulted in the Temporal Modulation Synthesis algorithm. I believe that with Flux I have now arrived at the perfect set of parameters to interact with the TM Synthesis algorithm easily. The ARM Cortex-M7 provides the processing power to execute the module with 64-bit double floating point precision, calculating rhythms with an extremely high degree of accuracy.

This next section has a lot of info about Temporal Modulation Synthesis, if you don't care about the details, prefer to experiment or just want to make exciting rhythms, skip to the Humanize section!


Temporal Modulation Synthesis applies a curvature to time, creating rhythms by modulating the linearity of trigger distribution within a step (each step can output a density of between 1-64 triggers). This video shows the density of a single step sweeping from 1 to 64:"

Don Martin's Moog Music Cincinnati Modular System

via this auction

Not the sharpest pics, but this is definitely not something you see everyday. A Don Martin Moog Modular. Don owned the rights to Moog Music while Bob Moog was running Big Briar. Bob sued Don Martin to get the name back in time for the release of the Voyager and Bob Moog's re-entry into the synth market. There was also Alex Winters in the UK who own the rights to the Moog name at the time, making Minimoogs (you can see one here). Don Martin also made a Minimoog, often referred as the Donimoog.

This is a fascinating bit of synth history.

From the listing:

"Don Martin's Moog Music Cincinnati Modular System
8 modules + Power Supply and cables
you can find info about these modules at and on the net (Bob Moog, Don Martin, lawsuit, etc.)

1 X 9501A oscillator controller
1 X 9501B oscilator
1 X 9504A low pass filter
1 X 9504B high pass filter
1 X 9503A random signal generator
1 X 9502 voltage controlled amplifier
2 X 9511 enveloppe generator

power suplly
connectors cables
s-trig cables (+trig converter if needed)

those modules are sold as collector items.

they are faithfull recreations of the first moog modular, using the same strange power voltage, fully compatible with original moog systems, but not with modern standards.

the high pass filter is not working properly, due to a component failure, but I can probably have it fixed.

I deliberately set a high price to avoid an impulse buy which could create a misanderstanding.

If you are interested, you can contact me, ask anything you would like to know and make an offer.

The photos are a little blurred so I will post more and better photos later.

Thanks for your interest."

Casio VZ-10M Rack Module MIDI Synthesizer

via this auction

"Included are the original manual, MIDI specification booklet, and two ROM soundbank cards in their original vinyl protective sleeves — the standard RC-100 card that was included from the factory, and the increasingly hard to find RC-110 "US COLLECTION". NOTE: The power supply is for 100-120V 50/60 Hz power only, and I'll include a normal grounded power cord for a buyer located in either USA or Canada.

Also, while this synthesizer module is in very clean condition (among the cleanest specimens I've seen actually) it is not strictly "mint". I've circled some minor scuffs in the finish in yellow in some of the listing images, so please look carefully — some of them I was hardly able to capture with camera and were otherwise something I had to really look for, but I also wanted to be absolutely transparent about the condition of the item you are buying. The display remains reasonably bright and easy to read, and is also free of scratches (as is the rest of the faceplate). There isn't even noticeable rack rash on the ears. The owner's manuals are in good, very readable, unmarked condition but the cover flap on the owner's guide is a bit torn at the bottom and like the MIDI spec guide exhibits some shelf wear.

Honestly I think this is in many ways a more charming synthesizer than the original Yamaha DX-7, for which this synthesizer along with its keyboard cousin (the VZ-1) were Casio's answer on the market to. The quality of the individual oscillators is (imo) noticeably better, there's ring modulation, and the timbres rawer and somehow "dirtier". It's noteworthy that sound output on this module is a bit crisper and quieter than those of the VZ-1 (and yes, even the DX-7). With the right timbres through a quality reverb, this could be a lovely instrument. Sadly, I no longer play."

New Wicks Patchy, handmade synth from Rare Beasts

Published on Feb 10, 2020 Rarebeasts

"The Wicks Patchy is a tiny patch synth that lets you experiment with sound by connecting modules in different ways using small cables.

You can be super creative with this instrument as you get to choose how the modules are connected.

This synth has 3 modules, VCO, Gate and LFO that can be connected in hundreds of ways.
The 5 controls at the base of the unit can be connected to any of the module inputs. To get started all you have to do is connect the power via a USB plug and attach your speaker or headphones. Now just attach one of the 5 controls to the VCO input and you are making sound, change the sound by connecting the modules in different ways. Instruction are included giving details of all the connections."

RolandJX-8P vs MKS-70 duel | Which one sounds best?

Published on Feb 10, 2020 Espen Kraft

"The MKS-70 is in fact two JX-8Ps stuck in a rack. It can be set up as a 12-voice 8P, split, dual, whole and unison mode.

But is the sound any DIFFERENT from a 8P, and which one sounds the "best"?

What do you think?
