Befaco diy modular synth & eml polybox

Befaco diy modular synth

Published on Jun 8, 2014 xamstradx·4 videos

"Having fun with my Befaco DIY modular synth (2010-2014, and growing)

Everything recorded in live, all sounds coming from the main output.

Patch 1 - Using MidiCV module ( Multi4 mode ), different sequences and filter functions.

Patch 2 - Using MidiCv module ( Poly mode ) trying some chords and pads. Don´t expect it to excel at this, it´s not what it is intended for. But with some tweaking you can still get some polyphonic goodness.

Path 3 - Random+rythmical pattern using internal functions (no midi here).

All sound recorded with the camera microphone, sorry for the poor quality

Kits are available at befaco.org."

eml polybox Uploaded on Aug 4, 2011 xamstradx·4 videos

"Got this eml poly-box for some years now, i decided to put up some quick demo due the lack of info, and sometimes curiosity, about it.
It´s is a cute, tiny, and exotic synth companion who basically turns a mono synth into a pseudo poly-synth (well not exactly, but more or less).
I bealive it was designed to work with EML electrocomp series. So to take the best of it you need a modular or semimodular device i´d say. Here it is with my diy modular synth.

'From the Peter Forrest guide to all things synth: 'A curious and rare product - only 130 ever were made. Designed to turn monosynths into pseudo-polyphonics. Twenty-six "note memories." Connect a monosynth audio out to the PolyBox input, play a note on the monosynth, hold down a chord on the PolyBox, and the PolyBox will fill out the chord from the original root note. Then you could route the PolyBox back into your synth (if it had an audio input) to use the synth's filter and envelope. The PolyBox's own sound was limited to pulse wave

Here is how EML describes it:
'Poly-Box is a pitch following variable chord generator controlled by your synthesizer and Poly-Box's own keyboard with built-in memory. Poly-Box takes a single pitch from your synthesizer and creates two banks of pitch sources. Each pitch bank contains 13 simultaneously available pitch sources at precise semitone intervals - covering an entire chromatic octave. The pitch banks may be in the same or different octaves, and can cover the range from one above to three octaves below the synthesizer oscillator.'"

ADDAC System Limited Edition Skateboard

"ADDAC System limited edition skate decks just arrived!"

Update via Andre Goncalves:

"Some further info regarding the ADDAC System skate deck:

ADDAC System + Fall Skateboards joint venture supporting the local skate community

This project was personally driven and it’s my public admittance of being a skateboarding fan
I picked up skateboarding in the late 80’s, and while i was never that good at it i kept riding throughout all the 90’s, did a 10 year hiatus when i moved to Lisbon but picked it up again in 2010 (really needed some activity that would take me away from the laptop and the soldering iron) skateboarding was still in my heart and still felt challenged by it so, without being too crazy about it, i cleaned the dust of my old skateboard, which by then was almost an artefact from the past, and started frequenting a recently built nearby skatepark. At the skate park there was a few people that were there almost every time i'd go there and we started getting acquainted, after going through the phase of them calling me Sir (damn, i felt old when it happened, most of them were born in the late 90’s some in the early 2000’s!!) we’ve become friends and I started to know them better, and how they deal with the urge to skate and the money necessary to do it. Skating can shred your wallet especially if you practice daily, shoes and decks only last up to 2 months this hoping you don't break a deck on some unfortunate landing. So i watch them struggling with these money issues while riding 2nd and 3rd hand boards all soft and chipped out which greatly influence their progression in the sport, i remember how the exact same thing happened to me 20 years ago and i felt compelled of supporting these young guys. I started by helping them have access to cheaper prices being the ebay intermediary and buying stuff online whenever they asked me to and from there i started thinking on this project, making decks to support the local skate community.
After a small conversation with our good friends at Fall Skateboarding we immediately started preparing this joint venture!

So, in this context, we made 50 decks from which 25 are reserved for the local park kids, these will be sold at production price becoming the cheapest decks in Portugal!
The remaining 25 will be numbered and signed by me and sold at 45€ per deck.

These are good quality decks, made of canadian maple hardwood with mellow concave.

All the very best and keep shredding!
Andre Goncalves"

Patch a Parametric EQ - Serge Synthesizer Tutorial

Published on Jun 9, 2014 Doug Lynner·23 videos

"Use three filters to create a parametric EQ.

Though this synthesizer tutorial is illustrated on a Serge the concepts apply to many modular synthesizers. Let me know how you apply this on your modular synthesizer.

Many thanks to Guest Host, San Francisco Sergian, Dmitri SFC of coa-modular (http://www.coa-modular.com) for this Patch of The Week!

soundmachines BI1brainterface MindWave to Control Voltage / MIDI equipment interface. Free your Mind.

"BI1brainterface Desktop Edition, this is it.
The picture is a rendering of the final product, currently in the final phase of hardware prototyping.

BI1brainterface, brain activity to CV/MIDI interface.
The product release will see two different version: the eurorack module and the stand-alone desktop BI1brainterface.
Functionalities are shared 100% between the two and we designed the Desktop Edition to be used by the non-eurorack customers!
Those will include big format modulars, MIDI based equipment, and more...
Both products will have an integrated user interface with a graphic OLED display that allows ther use to configure the machine.
Smoothing of the signals, trigger threshold, additional algorithms, scaling, midi channel and cc for each output are completely configurable.
We did not forget the tinkerers that, adding to the voltage outputs, will enjoy the availability of an RS232 interface that outputs the values of the EEG readings OR could drive the DACs by sending serial commands.
The BI1 is compatible with the Neurosky MindWave Mobile headset.

Korg Kronos Demo: Combi Gods Bathtub V2.0 QR

Published on Jun 9, 2014 Qui Robinez·48 videos

"Who remembered that great combi on the original Korg KARMA (the red one) called Gods Bathtub? It was one of the best combis of that synth. Now i've recreated that combi on the Korg Kronos and modified it to my personal taste.

It's called Gods Bathtub 2.0 QR and this demo shows the various elements in the combi, the KARMA programming, and the extra sounds."

Moog Releases the Werkstatt-01

Introducing Werkstatt-01 Published on Jun 9, 2014 Moog Music Inc ·267 videos

"The Moog Werkstatt-Ø1 is an analog synthesizer kit. Once assembled, you will have the satisfaction of owning a Moog synthesizer that you've built yourself. The Werkstatt-Ø1 is also an excellent platform for exploring the world of analog synthesizer circuits.

In this video, Moog Engineering Technician, Rosser Douglas, gives you an overview of the build process and functionality of the Werkstatt-Ø1 synthesizer.

Moog Werkstatt Analog Synthesizer Demo by Daniel Fisher

See the banners on the right (top and dealers section below) for shops that carry the Werkstatt-01. Support shops that support MATRIXSYNTH! They help make the site possible.

"The Werkstatt-Ø1: Moogfest 2014 Kit is a patchable and compact, one oscillator analog synthesizer. It was originally created as a kit, to be the foundation for exclusive “Engineering VIP” workshops at Moogfest 2014. Due to a number of requests, Moog is offering a no-soldering-required version of the Werkstatt-Ø1: Moogfest 2014 Kit in limited quantities, at select US dealers only. Assembly is extremely simple: Any user can quickly build an analog synthesizer based on classic Moog circuits, and if desired, study the analog circuits. Werkstatt was created to be an educational tool, but it is also a formidable, compact analog synthesizer from Moog."

Pendulum Ratchet simple patch

Published on Jun 9, 2014 Todd Barton·166 videos

"Here is a very elementary patch for the Pendulum/Rachet. Hope this helps those just getting started with the P/R.

What I love about it is the ability to "generate a bunch of correlated pulses." These pulses can then, in turn, trigger a 281e or two and, a 266e and, of course, a 251e/250e. When trigging the 281e it, in turn, can create lots of different CVs to send all around your system.

Chris Muir's design is brilliant and an incredibly powerful addition to any Buchla system. Here's a link to the PR description of functions:
