Custom Buchla modules - Synovatron

I'm finally getting around to building some half size Buchla modules.
This first one is a Euro to Buchla trigger converter.


I commissioned  these from Tony at Synovatron back in 2014.
Tony supplied the kits and two fully built modules.
The built modules are awesome. I use them all the time.

I'm putting together a second Buchla performance case and thus my need to get these kits built.



Almost there..

To be continued........

A tale of two computers - CSIRAC and Tec-1

This is a story of two Australian inventions that I think are worth remembering
as they both have a part to play in the evolution of electronic music.
One so big it will fill your house (if you possessed it). The other a fraction of its size that you can build yourself.

The first is CSIRAC.

CSIRAC  stands for Council for Scientific and Industrial Research Automatic Computer).
This was originally known as CSIR Mk 1. It was Australia's first electronic programmable digital computer, and the fifth stored program computer in the world.  She ran her first program in 1949 which makes her 70 years old this year.

I first saw this machine at the Melbourne Museum in 2016. (sadly no pics) . You can today pay her a visit at the Scienceworks centre, also in Melbourne.  (Maybe take her a birthday cake)

 CSIRAC is the oldest surviving first-generation electronic computer (The Zuse Z4 at the Deutsches Museum  in Germany is older, but was electro-mechanical, not electronic). CSIRAC was constructed by a team of scientists led by Trevor Pearcey Geoff Hill and Maston Beard. Though it had but a fraction of the brain power of your average smart phone it was a revolution in its day.

In addition to being used for things like weather forecasting and banking,  CSIRAC was the first computer in the world to play digital music. This took place during Australia’s first computer conference in June 1951. The tune was Colonel Bogey, . Sadly there are no recordings.


The second Computer we are looking back at is the TEC-1

 It is a single-board kit computer first produced by the Australian hobbyist electronics magazine Talking Electronics in the early 1980s. The design by John Hardy and Ken Stone was based on the Zilog Z80 CPU.

If you are a regular reader of this blog you will probably know who Ken Stone is. The founder of Cat Girl Synths (CGS).

Th TEC-1 used a  Zilog Z80 CPU, had 2K of RAM and 2K of ROM in a default configuration.

Those twenty round keys on the right are the main input. They are made up of 16 hexadecimal keys for numeric inputs and address, a GO key to execute a program, + and - keys,

This is the original prototype.

The TEC-1 was first featured in 1983, in Volume 1, Issue 10 of the Talking Electronics magazine, pages 57 to 75. I plan to build one of these and will document it in a future blog and hopefully use it to play a tune or two ... maybe Colonel Bogey.

It the 1984 issue of Talking Electronics magazine,  (Volume 1, Issue 11, pages 11 to 36, and pages 50 to 55) are two peripherals designed by Ken Stone for the TEC-1 -an 8x8 matrix display, and a relay driver board. These allow the TEC-1 to be interfaced to other equipment.

Notes:
+ Colossus (1943) was the first electronic digital programmable computing device, and was used to break German ciphers during World War II. In December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February. Colossus included the first ever use of shift registers and systolic arrays, enabling five simultaneous tests, each involving up to 100 Boolean calculations, on each of the five channels on the punched tape.
A reconstructed working copy of one of the Colossus machines is now on display at Bletchley Park.

+ ENIAC (1945) (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in the US. ENIAC was the first Turing-complete electronic device, and performed ballistics trajectory calculations for the United States Army.

Lorre-Mill U Tone build notes

Some pics of my build of the U-tone diy synth.
Looks like a cool way to learn about CMOS ICs.

Lorre Mill make the wonderful Double Knot synth.


"The utone circuit uses CMOS logic, a resistor ladder, and a few other simple pieces to create audio forms. The scale inherent in this instrument is the undertone series, giving divisions of the main clock frequency."

Only the PCB is supplied



I'm not sure how I will eventually encase the synth.
I may end up incorporating this into a larger project.

tHE CMOS ICs used are a CD4046BE & two CD4015BEs

The CD4046BE is a PLL (Phase Locked Loop)
The CD4015 is a Counter Shift Registers, Dual 4-Stage








 Quite a easy build.


Lancaster's CMOS book is the bible


I'm not sure how i'll encase this.

An evening with This Is Not Rocket Science


Teenage engineering - They have gone modular

I was surprised and delighted to see this today.
I'm a big fan of this Swedish company.

The teenagers have got a new series of synths out.
Beautiful Scandinavian designs.
Their website describes this as the poor man's modular but I can see these being sold in art galleries.

The System 400 (as my friend Justin pointed out) harks back to the EMS Synthi E
And I think the similarities are more than just its colour

The Synthi E was designed for education, and I feel that these new TE synths will open up the world of modulars to a much wider audience.


The flat pack idea reminds me of  IKEA. Another Swedish company... who are known for selling good, minimalist designed products at affordable prices.

As far as I can tell from the manual, the patch cables are 3,5mm but the module size is their own format (not Eurorack).

The 400 has  3 OSCILLATORS, NOISE, RANDOM GENERATOR, 2 ENVELOPES, 2 VCA'S, LFO, FILTER, MIXER, SPEAKER BOX, POWER PACK AND A 1–16 STEP SEQUENCER.

THE COMPLETE KIT COMES WITH CHASSIS,16 MODULES, 15 PATCH CABLES.

It doesn't look like you can move these modules around within the system.
The kit comes with a flat metal face (reminds me of my old Meccano set) where you bend (the edges) to make the case...

The modules are then screwed onto the back of the face ??


The other two synths released are the 170 & the keyboard

The 170 is a analog monophonic synth with step sequencer. It costs $349USD and includes a chassis, nine modules and eight patch cables.
The modular membrane keyboard has tuneable keys and a step sequencer. It seems to be designed for use with the 400 & 170 model... and hopefully will conform to Eurorack CV/ gate standards

The module dimensions are here.

The TE system uses M2 screws., 5mm spacing mount holes. Module dimensions are 30x90 for a 6HP module. ie the height is 90mm which is approximately 2U

Euro specs are M3 screws, 5.08 mm spacing mount holes, and a 3U height.

But the PSU  is compatable ... both +/-12V

I hope this is the first of many future module additions. Maybe a case that allows for free placement of the modules..... I can see this system expanding

Masters Of Modern Sound - AGNSW

An awesome exhibition. There is one more day to see this music/painting combo.
I saw this last night.
This is part of the Festival of Sydney 2019




The program:

Shchukin, Matisse, Dance & Music

This multimedia installation is by Saskia Boddeke & Peter Greenaway.
Shchukin comissioned the paintings Dance & Music for his Moscow residence in 1910.
They are now in the collection of the Hermitage.
The dancers are from the Dutch National Ballet and music by Italian composer Luca D’Alberto,

I enjoyed all the performances esp Caterina Barbieri
http://djjondent.blogspot.com/2019/01/caterina-barbieri-masters-of-modern.html

If you miss the performances, there are still these masterpieces to see.
Some of my fav pieces:
Cézanne, Fruit 1879/80; oil on canvas, 46.2 x 55.3 cm, Inv GE 9026, The State Hermitage Museum, St Petersburg

Kandinsky


Sonia Delaunay-Terk’s illustration of Blaise Cendrars' text



Othon Friesz - Roofs & Rouen Cathedral, 1908

Henri Matisse

Black Square (1932)
I wish there was more Malevich.Can't get enough of this guy.



Corin Illeto, Becky Sui Zhen & Casey Hartnett performed surrounded by masterpieces of the Hermitage.



You can see the Masters of Modern Art from the Hermitage till March 3rd, 2019.



Caterina Barbieri - Masters Of Modern Sound

I really enjoyed this performance last night at the Art Gallery of NSW, Sydney, Australia.
This was part of an exhibition of art from the Hermitage, St Petersburg, Russia.


The exhibition attempted to fuse the paintings with modern music.

Thank you Caterina.


I was blown away with the breath of sounds Caterina was able to provide with such a small rig.
A lesson that less really is more.

For the geeks out there who are wondering about the system format. As far as I could tell from a distance:
Case: Make noise 7U shared system with a central CV bus.
Top row: Orthangonal Devices ER 101 sequencer, Make Noise Echophon, Erb Verb,
                LxD filter VCA,   Maths, Optomix (Voltage controlled filter/amplifer/LPG),
                Doepfer 190 USB midi to CV
Bottom row: Verbos Harmonic Osc, Make Noise woggle bug & DPO, ALM Pamelas workout,
                    Doepfer 135-1 VCA/mixer, doepfer A-105 VCF SSM 24dB Low Pass & Doepfer ADSR??

Possibly, Caterina was using a laptop to process the audio. Not 100% certain about this. I read somewhere she uses Abelton and is a fan of the ping pong delay. That's a Novation midi controller at the bottom with a MOTU audio interface.

RIP Alan R. Pearlman

A good innings.
He can stand shoulder to shoulder alongside the likes of Don Buchla & Bob Moog.

Alan was born in NYC in 1925. He worked for NASA and served in the US military before founding ARP instruments ( (originally Tonus, Inc.) in 1969. He designed amplifiers for NASA's Gemini and Apollo programs


ARP shaped the early development of analog Synths.
These 2500 & 2600 synths were and still are among the greatest synthesizers ever made.
I love both these instruments. Though many describe the 2500's matrix as unreliable, I wish more manufacturers would adopt this technology. It really makes the 2500 special.

The 2600 was produced from 1971 until 1982. Instead of the matrix, it used traditional patchords.
The synth has preset internal connections so users can get sounds out of it & play it straight away without any knowledge of modular synthesis or patching.

These internal connections are broken when a patch cable is inserted, making this synth 100% modular. This was I think one of the earliest if not the first time such a idea was implemented.  It's so common these days and most people don't give it a second thought. Alan was a true pioneer.

A great sequencer !!!

The ARP Little Brother was meant to be a companion to the 2600.


These are battery powered modules (9V DC). They were intended to educate kids.
The modules helped to teach me be the basics of synthesis.


The ARP Avatar guitar synthesizer.

Thank you Alan.
(June 7, 1925 – January 6, 2019)
