Synthé modulaire compilation for free


In 2010 a new, French speaking forum about modular synthesis was born : Synthé modulaire and soon its founder, Mechaseb, came up with the idea of putting together a compilation of modular works made by the members of the forum.

So here it is now, free for you to download and enjoy : Compil Synthé modulaire 2011

This is a collection of tracks made with EMS, Serge, Buchla, Eurorack, 5U and SDIY modulars, showing off the huge potential of modular synthesizer systems resulting in the diversity of productions found on this compilation.

These tracks are not copyright protected but are intended for home use only.
Please feel free to contact me by e-mail for more information, or even better, come and visit our forum, become an active member of this lovely community of passionate modular synthesizer owners.

Enjoy !

Zeitdehner goes BIG

So, finally it arrived, on a beautiful summer day...my first 5U, Moog unit modular by Mos-Lab.


It took 6 months from the moment I confirmed my order to delivery of the modules.

Why so long ? Well, because Mos-Lab is a one man show and Sébastien, the man behind Mos-Lab, had to finish a few other orders before he could take on building mine. He works on an order by order basis and he does no stocking of items, he needs to outsource PCB and panel manufacturing, needs to source hardware and components and therefore he is dependent on delivery delays by his partners. That is obviously often the case with small manufacturers in modular business.

Why Mos-Lab ? Well, because I wanted to go back to the roots of modular synthesis and enjoy classic analogue sound, with a classic feature set, with classic ergonomics... and that's exactly what Mos-Lab delivers : faithful reproductions of original Moog modules.
Ok, but why no Synthesizers.com then ? Because Mos-Lab is a French manufacturer, which makes for easier, faster and cheaper shipping to Belgium (where I live)... no customs or import taxes, no VAT... and the price/quality ratio is excellent. This proximity facilitates communication and possible after sales logistics.
Also, Sébastien is quite a fine chap, very smooth and correct to deal with and he deserves to be successful with his business (don't they all do, so we can keep on playing those wonderful instruments).

So, what's in the box ??


All modules are well packed and protected, separately.

After unpacking, I placed all the elements, just to see if they fitted the cabinet I made more than a month earlier :


Then I fastened and connected the whole lot :


Now, let's have a closer look at those PCB's :

 Above is the filter trio : HPF, coupler and LPF
These are the three VCO's, the driver and controller

All PCB's are stuffed with discrete components and very few analogue chips. Circuits are not very densely populated, no SMD here... all in respect with Moog's original circuits (with just a few improvements here and there).

Now, let's see how this synth looks from the front :


I designed the cab to hold 2 rows of 12 MU . Shape and size remind that of Macbeth's M5.


When thinking about the system configuration, I deliberately chose for a basic selection of sound sources and treatments, to have a full Moog like quality audio path, leaving modulation and utility tasks to modules from my Eurorack system :


Upper row :
- CP10 mixer
- 904-A LPF
- 904-C filter coupler
- 904-B HPF
- CP10 mixer
- 905 spring reverb

Bottom row :
- 992 controls to oscillators
- 921-A oscillator driver
- 3x 921-B VCO
- Moon Modular 2U blanking panel with logo
- 2x 995 attenuators
- 911 envelope generator
- 2x 902 VCA

The blanking panel is there to replace the no longer produced, very rare and elusive 970 waveform processor (clipper/ring modulator) that I intended to include. The 970 just went out of production a couple of weeks before I placed my order . Though, I 'll be getting a 970 that I found second hand in the next few weeks :-)



  A family shot with his playmates : Moisturizer, The White Dwarf, FriFri Deluxe and Little Putney :



Just about a week after having received my system, I found a second hand 905 spring reverb and I couldn't resist grabbing it  for stereo reverb or to use in 2 voice multi timbral context, so here's the system as it looks today :


First impressions:

Assembly of the PCB's is done quite carefully and overall build quality of the modules is very good.
The hardware feels very solid and secure, controls are very smooth and well calibrated.
Layout of panel controls is logical, clear, very roomy and comfortable, which makes for easy access even with all ins and outs patched up.
The lack of attenuation on CV inputs makes several 995's, mixers and  VCA's indispensable.
Overall sound is very rich, wide, vibrant, organic, with bags of character. Both PWM and Sync are very effective and musical.
This system is taylor made for very expressive, classic leads and basses but also proves to be very effective at FX and more abstract or atonal works.
The LPF produces a very nice sine when driven into self oscillation, though with limited frequency range...it goes higher than it goes low... still, very much usable!
The HPF  also has a nice character and comes in very handy for all sorts of applications.
The filter coupler provides for band pass and band reject duties, putting the LPF and HPF in series or parallel. This one is a bit more tricky to master, but, when used correctly, provides a wide palette of very interesting timbres.
Both filters have a very nice and natural saturation at high input levels.
Oscillators are quite stable but not too much... there's just enough drift to have some movement and life in multi oscillator sounds. Also, tuning of the oscillators is a breeze and fine tuning is very precise. It makes it very easy to dial in a beating in between oscillators or to iron it out by dialing in the exact same frequency... very nice !
The envelope is quite snappy and it does a fine job but I miss a manual gate...
Reverb is quite nice and natural even if I would have liked it a bit less nice at times... with the possibility to distort the signal... like on an EMS synthi...

In conclusion:
This Mos-Lab synth had me waiting for a long time but it was well worth the wait. I now feel like I'm discovering real analogue modular synthesis again... leading me into uncharted sonic territories. This is such a different experience from Eurorack, on sonic level as on functional and ergonomic levels. Not better or less good, just different...and complementary. It's true that Mos-Lab modules are very "basic" but in combination with all the "crazy" modulators and treatments I have available in my Eurorack system... this is quite an explosive cocktail !
I'm so excited about this that I'm already planning on expansion of this rock solid, classic Mos-Lab modular  with some more "modern design" modules by Rob Hordijk, Oakley, COTK, ...

The never ending story...

Each time new modules arrive it is the excitement of reshuffling the setup, mounting and dismounting modules to fit the cabs, trying to keep the balance between aesthetics & visual symmetry, ergonomy and functionality. Time consuming, quite laborious but lots of fun. Once that is done, it is time to explore the functionality and possibilities of the newcomers... even more fun!

The following is a photo report on the evolution of my setup that shows the various incarnations of my modular over the past months up to it's current state. Enjoy !

An overall shot of the studio in those days and a close up on some dual channel oscilloscope madness





04/2010
Got myself a second Analogue Systems RS-15 case with some modules, also some more Livewire, a Tiptop Audio Z8000 matrix sequencer and a Roland System-100M 184 polyphonic 4CV/Gate keyboard



05/2010
Yes! I finally got a second hand Livewire Dual Cyclotron and replaced all the knobs by 19mm Eagle fluted ones

Ooops ! This is not mine ?! ... it is my friend Constantin's amazing dual EMS setup with his SDIY interface... beautiful !! I couldn't resist posting this one

Added a third RS-15 with some sequencing goodies

Yes! those knobs look and feel quite good

06/2010
At last... the Livewire cab is completed with a second AFG... thanks Nav ... massive  !

Preparing to incorporate my forthcoming SDIY FriFri Deluxe patch matrix/attenuator bank. Notice the two reverb tanks mounted externally, on top of the cabs

10/2010
Here it is, installed and all patched up (more on this in my SDIY page)

A broader picture of the whole lot, unpatched

02/2011
This latest setup saw the addition of some Plan B, Oakley and Synthesis Technology modules in the top right cab


3/4 2011


The latest additions to my setup are two STG Soundlabs modules, the Wavefolder and the Sea Devils filter.



Both circuits are based on Yves Usson designs.

The first, as its denomination suggests, will "fold" any incoming signal. By doing so, the Wavefolder will output a more complex signal and produce new harmonic content. Obviously , it works best on simple waveforms of audio signals. There's an Offset control that will determine at what "level" of the waveform the folding will occur. For instance, by adjusting the Offset appropriately, one could apply folding only onto the positive period of a bipolar signal. Fold mix control makes the balance between the original signal  and the folded signal. Gain control is a VCA on the input stage of the folding circuit.
Voltage control is provided for Gain (with attenuator) and Offset.
Basic application of the Wavefolder is to render a rather dull waveform more harmonically rich.
Wave folding can produce comparable results to those obtained with wave shaping or wave multiplying.
The Wavefolder is not a module I use very often but its use can be very rewarding if set up correctly.

The Sea Devils filter is a diode ladder design inspired by the circuit found on second generation EMS Synthi A and AKS, with a 24dB slope.
As its pedigree suggests, that filter has bags of character, it "sings" very well at high resonance settings,  with a huge frequency range and it tracks quite well to 1V/Oct...that makes the SDF a great sine oscillator to provide powerful bottoms with good definition and crispy, precise highs.
Also, it responds very well to fast, audio rate frequency modulation.
Volume drop at high resonance settings is not too obvious and there are lots of sweet spots just before and after the point of self oscillation.
At high input levels, the SDF delivers smooth saturation, which is very nice.
Voltage control is provided for Resonance, there are two 1V/Oct frequency modulation inputs and there's one scalable frequency modulation input with attenuator.
All of this makes the SDF my favorite in my current setup. I love it even more than the Analogue Systems RS-500e, which is also an EMS based diode ladder filter circuit.

Both modules are 14hp and benefit of roomy front panels. They are quite deep, so they won't fit into a skiff. Panel control layout is clear but positioning of the control input jacks can be somewhat confusing as they are not placed right next to or under their respective parameter. Build quality is excellent and working with these modules proves to be a very satisfactory experience.

Looking forward to grab a Post Lawsuit filter ...
