Squid Axon - NLC - Build notes

These are my build notes for the Nonlinearcircuits Squid Axon Eurorack module.

The Squid Axon is a circuit based on the Hodgkin- Huxley
 equation describing the chaotic behaviour observed in giant
squid axons.


Andrew's Build notes are here:
http://www.sdiy.org/pinky/data/Squid%20Axon%20build%20and%20BOM.pdf

Andrew's Blog info:
http://nonlinearcircuits.blogspot.com.au/2016/03/squid-axon.html

Basically it's a 4 stage analog shift register with two feedback paths, one nonlinear and one linear.


 I like to get the surface mount ICs on first.


I'm using this DG411 - from mouser.
 According to the specs, it requires the 100K & 120k resistors.

See Andrew's build notes.

 Get the rest of those SMDs on the board.
You're nearly there.

Pauline Oliveros RIP

Pauline Oliveros will be sorely missed.


The picture above is of her with a Buchla 100.
She was a central figure in the development of experimental and post-war electronic art music.


Pauline was born on  May 30, 1932 in Houston, Texas.
She passed away on November 25, 2016.

Oliveros, along with Morton Subotnick and Ramon Sender, formed the San Francisco Tape Music Center
in the 1960's.
She made a huge contribution to the development of Electronic Music.
Her legacy will enrich the lives of generations to come.

Fairlight CMI IIx - Demo - Locust

This is one of the demo tracks that was released in the 1980s for the Fairlight.
The Fairlight I'm using is vintage 1982.

All sounds are from the fairlight with no added effects, etc

 It's important to load the instrument file (LOCUST.IN) first, then load the .RS file (LOCUST.RS)

 Opening page for the Locust tune.

Fairlight CMI - Page 9. The Keyboard Sequencer

Here is Page 9 with replay file ALHUMBRA.SQ loaded.

The sequence file was loaded from this disk which can be viewed via page 2:

Here are some help sheets for page 9:





Nara, Japan

Nara. Japan's ancient capital (8th century).
Today, it's the capital of Japan’s Nara Prefecture, in south-central Honshu.


Nandaimon, the Great Southern Gate.

Main Temple, Nara.
Tōdai-ji temple.
Tōdai-ji (東大寺?, Eastern Great Temple) is a Buddhist temple complex, that was once one of the powerful Seven Great Temples, located in the city of Nara, Japan. Dates to 728 AD.
It's the world's largest wooden building.

. Daibutsu, Tōdai-ji's 15m-high bronze Buddha.


Komokuten, one of the pair of guardians in the Tōdai-ji temple.


According to the legendary history of Kasuga Shrine, a mythological god Takemikazuchi arrived in Nara on a white deer to guard the newly built capital of Heijō-kyō. Since then the deer have been regarded as heavenly animals, protecting the city and the country.
Tame sika deer (also known as spotted deer or Japanese deer) roam through the town, especially in Nara Park. (Wikipedia).



On the park's east side is the Shinto shrine Kasuga Taisha, which dates to 768 A.D. and more than 3,000 lanterns.

Fairlight Synth - Initial pics

Thought I'd upload some pics while this baby is behaving.
At times she has a mind of her own.:-)

This is the first page you will see when the Fairlight boots: Page 1, the Index.

Page 2: Disk Control
Provides a directory of all the files currently loaded.
Type P2<return>  to access page 2.
Files with the ending ".VC" are voice or sound files.
Files that end in ".IN" are instrument files.

Type L,A,filename<return> to load a file.
This is Page 6
Page 6 (Waveform drawing) can be accessed by typing P6<return>

This page allows direct drawing of audio waveforms using a lightpen.

This is page 7 (Control Parameters)
This allows you to set, modify & control the parameters for each sound file such as the volume, attack, decay, portomento, etc

You can of course reach this page by typing P7.
  
And finally the famous "Page D"

It's the Voice Waveform Display.
You reach it by typing "PD<return>"
Page D shows a 3D picture of the waveforms of any voice.

There are 2 formats:
A (above) and B (below)
Format B has a much higher resolution than Format A, but is less "3D" in appearance.

3trins to banana breakout box


The 3trins mini patchbay is wonderful but at times difficult to see (esp in low light).
And I'm a big fan of bananas. .. they are stackable and fast.


My initial attempts were to build a permanent panel.
Soon ditched this in favour of one that I can plug in and remove when I like.


I'm using mini bananas:
