"OCS-2 is a digital, semi-modular, analogue style synthesizer. Small, but very powerful and flexible, it provide an incredible sound quality. Dedicated to knob addict, this synthesizer is full of feature that define it’s own unique sound.
Why is it so special?
First, the sound quality is impressive : this is not a cheap 8 or 16 bits synthesizer : it implement state of the art audio synthesis algorithm.
OCS-2 provide lot’s more than the essential of a modern dual oscillator monosynth. Original waveform, shape morphing LFO, there is a lot of unique feature :
30 control knobs
Few atypical waveform with incredible fat sound
LFO that can continuously change waveform
A CV GENERATOR with different algorithm to generate random to rhythmic modulation
4 audio effects A very powerful digital connection matrix
A light sensor to control sound with hand gesture
Customizable and possibility for software update
Very compact
Incredible sound quality
What is inside?
2 VCO providing 15 different waveform
1 VCF (multi-mode, including a 24db/Octave low pass resonant filter)
1 VCA
1 ADSR
3 LFO (2 with configurable waveform, 1 with CV frequency control)
1 custom CV GENERATOR with 4 different algorithms (Attack Release, dual LFO, Random, Non Linear)
1 audio effects processor with 4 different effect (Distortion, delay, bitcrush, waveshaper)
1 ring modulator
1 CV controlled MIX (for VCO1 and VCO2)
2 octaves keyboard with portamento
1 digital matrix to connect CV to modulation fader
1 Stereo line-IN with envelope follower and gate control
1 MIDI input (note / velocity / pitch wheel / modulation wheel / control change)
3 analog CV IN and 1 GATE IN
1 light sensor
Why will you love it?
Since it is very small, you can carry this synthesizer everywhere. You can even use a 9V battery as power supply. With an embedded audio multi-effect, you don’t need anything else!
But this synthesizer can also adapt to your setup: add a midi keyboard and your ready for endless jam.
OCS-2 is also perfect as a computer complement : prepare some midi loop and use them in combination with the modulation faders as CV controls.
With a line audio input, 3 analogue Control Voltage In, and one 0/5V Gate IN, OCS-2 can also be a great addition to your modular setup.
The extensive number of physical control allow an easy and effective sound tuning. 30 faders intent a direct access to all sound parameters, so you can only focus on the music.
The light sensors is also a great for music expressiveness : use the shade of your hand to control your sound! Your performance on stage will never be the same thanks to this feature. This is also attractive for studio work since it introduce a very different control than a fader rotation.

The image to the left is via modulargrid. It appears the brand will fall under the moniker auxren.
The following are some details in via Oren:
"This one is mainly open source and meant to be a non-daunting way for people to learn to surface mount solder. The files and info is on github.com/auxren/tripsquad.
Cost for parts and everything is around $60. I'll have circuit boards and panels for purchase and I might even hand build some if people want complete modules, but the purpose is to get people to build something easier than the other surface mount projects."
Premières notes du synthétiseur Quinoa - First notes of the Quinoa synthesizer

A ce jour, le synthétiseur "Quinoa" est quasi terminé et l'on peut déjà en sortir quelques notes.
DIY (Do It Yourself) synthesizer. The sources will be shared soon.
Actually, this synthesizer called 'Quinoa' is pratically finished and we can heard some sounds."
"Ardurack is a multifunction eurorack module based on Arduino.
It has 8 functions all centered around pulse/square signal:
Trigger by the push of a button (2 to 100ms per impulse).
Tap-Tempo trigger (2 to 100ms per impulse).
Modulator, a voltage controlled square wave LFO. Frenquency range is fixed between 0,5Hz (2000ms) and 15Hz (65ms).
Simple square wave VCO (gated or continuous mode).
Complex square wave VCO 1 (gated or continuous mode).
Complex square wave VCO 2 (gated or continuous mode).
Noise (gated or continuous mode).
440Hz Tuner
The conception and functiunalities of the Ardurack make it differ from other modules in it’s own unique way.
Every single mode has it’s own particularity. They may seem simple at first but with well-thought and clever addons, they transform the module in a complex utility workload machine! For instance things like having a hold option on the trigger when it is high, the doubling of the modulator period by the simple push of a button or the gated mode on the VCO’s which avoids the need of an external VCA.
The developing philosopy of the module started from one constraint: The Arduino ProMini board based on the Atmega328p microcontroller. The idea is to extract all good working signal from this chip for the eurorack world. This chip only provides digital signal or square waves. Therefore every output mode is based on square wave / pulse / triggers.
Eventhough it is deliverd fully assembled, functional and equipped with the different modes explained, it is up to you to make this module yur own. You may upgrade or downgrade it’s hardware or firmware! It is possible to re-programm it with the Arduino environement and an FTDI adapter. You may also want to add more inputs and/or outputs out of the non-exploited I/O on the ProMini board. You buy the hardware, the assembly and the developping, the rest is up to you!
As to say, it is also the first official module from Cavisynth Labs.
First of a long list to come!"
"SEQ-UFD is a fuly & small ( 18HP ) 8 step sequencer based on Arduino.
To begin with, why this name: SEQ-UFD ?
Ok, I think “SEQ” it’s obvious, but “UFD” ? no idea?
This means absolutely nothing! Maybe you can found something but the only way is a pun in French.
In French, SEQ-UFD is pronounced the same way as C.Q.F.D (cé. cu. èf. dé )
C.Q.F.D: “Ce qu’il fallait démontrer” -> This was to be demonstrated. Voilà!
Number of steps selector controled by knob
Multimode controlled by knob or CV
Internal or external clock ( internal: 20 to 2500 ms )
Trigger output: ideal for EG (70 ms)
External clock input + reset steps input
8 separated gated output ( like Doepfer A-161 clock sequencer )
8 steps with voltage controled by knob
CV outpout with range controled by knob
List of available modes:
Like the Ardurack, the developing philosopy of the SEQ-UFD started from one constraint: The Arduino ProMini board based on the Atmega328p microcontroller.

Quit using blind panels and fill up that extra space in your rack with 2hp modules! These modules are packed with tone and utility. And at $150 a piece, how can you pass them up?
Also featured are Expert Sleepers Disting mk3s and the FH-1. The FH-1 is translating the MIDI from Ableton Live into 1v/oct control voltage and gate information, and the Distings are working together to create a CV signal for the FM input of the Osc module - a little vibrato!
Tim Trzepacz is the man behind SoftEgg & Rhythm Core Alpha. He also developed a modular keyboard design as you can see below.
"(S1 / E4) Supplyframe DesignLab opened its doors this July to four creative resident teams building hardware projects in Art, Design, Technology, and Science. The new series 'Open Source' follows DesignLab residents step by step in their creations. Episode 4 explores resident Tim Trzepacz and the creation of his music hardware synthesizer the NanoEgg. After successfully launching a software synth developed for the Nintendo, Tim has begun the journey creating a fully analog hardware synthesizers.
"'I also do crafty stuff like display stands for my product and portable stages and such,' Trzepacz says. 'I love performing, and will play music anywhere. I’m really active in the greater Los Angeles chiptune scene, and for that, I need to make interfaces to do stuff on Arduino and Propeller boards.'
Now with this multi-part design for a synthesizer controller keyboard, Trzepacz says he wanted to create a modular design which would allow designers to 3D print as many sections as they need."
"Double Knot is a patchable synthesizer system which is both sequencer and voice. It can be thought of as something of an indeterministic "groovebox". A stereo instrument with two identical voices that can give different rhythms, melodies or cross timbral slaps. The idea of this instrument is to invite reconciliation of linear and nonlinear systems, and to encourage the building of multiple-feedback synthesis architectures. User interface is with rotary potentiometers, switches, and banana cables. Patching puts are banana ports of round brass tube. Clock in and out are 3.5mm jacks bearing 5V square waves. Audio output is 3.5mm line out."
We a new maker in town! This is the first Lorre-Mil post here on MATRIXSYNTH.
"This is a rough demonstration of a home-made synthesizer named the 'ESL i-Lander.' The synth is a combination of purposely short-circuited electronics from a toy keyboard and parts from a MIDI keyboard that utilize iPad effects synthesis. iPad programs used are Audiobus, Loopy (to create loops from the audio of the ESL i-Lander), Turnado by Sugar Bytes (MIDI effects synthesis), and Cubasis (the DAW recording all audio)."

"Making sounds with a home-made synthesizer that is a combination of purposely short-circuited electronics from a toy keyboard and parts from a MIDI keyboard that utilize iPad effects applied to the short-circuited sounds. Toggle switches, a big button, and a small reset button were applied to the new, short-circuit sounds of the toy keyboard electronics."
"This is my eurorack filter with a Curtis CEM3320.
2/4 pole switchable, normal / hard saturation, 2 channel mixer, resonance and frequency cv.
Playing around a little bit"
"Based on Digisound 80-6A."
Update: I asked RyuX if this was a one off or if they would be made available in any form. He said, "I have made a couple of PCBs for the prototype, of course i had to do some modifications to have it fully working. It would be possible to give away some PCBs along with Instructions. I don't plan on giving away completed modules as the CEM3320 Chips are very rare."
There were rumors of the CEM3320 being re-issued when the new CEM3340 was announced, so there might be some hope.
The above is a demonstration by Adrien Duchemole who is lucky enough to own one of the first Ondomos.
[Update: I found a few additional demos of the Ondomo on YouTube. Three, including the initial unveiling of the first version in 2014, have been added to the bottom of this post.]
In October of 2012, a post here on MATRIXSYNTH featured the Asaden Eleki-Ribbon. It appears that project was just the start of something pretty magnificent. Asaden has painstakingly recreated his version of the Ondes Martenot. Details follow.
Pictured here is an image of two new Ondomos and an original Ondes Martenot (center) via Adrien. Note the wood on them is much darker than the one pictured below from the Asaden website. According to Adrien, Asaden did an initial run of 100 Ondomos.
The following are some details, Google translated from Japanese, via Asaden (forgive the translation):
"Ondomo - Legacy Of Love
More than 15 years, continues to study the Ondes Martenot, it can be more easily available, it is even more portable also easy, anywhere play as, from Japan made from the feeling that new Ondes Martenot.
Once the Ondes Martenot easy Mochiaruke ... Ondomo that has been produced in such a thought (Ondomo) has packed the hopes and dreams in only 64 cm of width.
If even plug it into an electrical outlet, because it is equipped with a built-in speaker, you can play anywhere at any time.
Instrument called Ondes Martenot, and Ondes Martenot unique sound is hoping the producer that the more spread in the world."
"1928, is an electronic musical instrument was born in France. Announcement initially referred to as the (meaning of the Buddha 'musical waves of Martenot') 'Ondes Martenot musical-Ondes Musicales Martenot', it will be later referred to as the 'Ondes Martenot' or simply 'Temperature ondes'."
"Morris Martenot (Maurice Martenot, 1898.10.14 - 1980.10.08) represents a musical talent from early childhood, early on cello, piano, musician learned the basics of music, also deeply involved with music education and thought, in his later years Mesodo of relaxation is also established. On the other hand, there is a deep knowledge in electronic and mechanical engineering, in the First World War in prison as a communication soldier. Ondes Martenot The impetus of production is, where you start from the sound clear the triode vacuum tube was in the ear. Repeat the research and trial along with the end of the war, Paris in 1928, it announced the musical instrument in the Opera, and caused a sensation. Then, playing to countries with Ginette Ginette of the Ondes Martenot player sister trip, in 1931 we came to Japan in Japan. Ondes Martenot for the Morris, and the desire of as a musician to continue to seek a sound of its own, desire as a thinker to practice the human way and way of life are fused, will he had a life's work would live ish myself. 1980, continue to seek the sound of his own until his death in an accident, improvement until the end instrument was overlaid."
"And a body part to play, set in a variety of speakers (Buddha di Few Suhl Diffuseur). Its kind, there is a regular speaker and similar principal principal, resonance resonnances to create a reverberation by spring, a built-in gong characteristic resonance of metallic metallique, Palm palme to leave a sound strings stretched wooden body.
