Electric City @ Society City
Thanks to Ed (Elk Elektroniks) & Josh (Society City) for teaming up for the synth meet
last Sat (23rd Sept) in Wollongong, NSW (Australia).
It's primarily a book store that doubles a a co-op collective.
The volunteer-run art-space, cafe / bar, bookshop and community venue that is perfect for arts, music and collaboration.
Electronic music, Jazz, Poetry, book reading, movie nights.
Everyone needs to utilise this space to keep it open and running for the local community.
Hopefully this will become a regular meeting.
Carsten's preparation (at my place) using the AE modular

Cat Full of Ghosts - XCHGN - video exchange - build notes
Some build notes for the CFOG XCHGN video module
Some personal build notes
Here is the link to the official CFOG page
Most of the parts can be
purchased from mouser
This video module is Eurorack compatable, though I'll probably use it standalone.
It's a "dirty"video mixer that I plan to use to expand my analog video gear.
pretty sound advice :
Small video mixers are not common so this looks worth a try.
This is described as a "dirty mixer" so I expect it will distort the signals as
I transition from one channel to the other.
The RCA connectors
DPDT : on-none-on
x 1
SPDT switch x 3
on-off-on
1k pot - linear
Inductor
a pretty easy build..
The final pic
The XCNGN (exchange) is all about getting more out of vintage analogue gear.
So what does it do?
The main features include:
- Two x 2:1 switches to add two additional inputs to your video mixer
- A dirty mixer for creating distortion and disruption as you transition between two video inputs
- A passive sharpener to heighten the edges of your signal (a classic effect)
- A loop out/bypass function to switch from direct feedback to feedback with effects instantly
- Two x 2:1 switches to add two additional inputs to your video mixer
- A dirty mixer for creating distortion and disruption as you transition between two video inputs
- A passive sharpener to heighten the edges of your signal (a classic effect)
- A loop out/bypass function to switch from direct feedback to feedback with effects instantly

Korg Kaptivator - video sampler effects mixer
The Korg Kaptivator dates from the 1990s
This is a mix between a Roland Edirol video mixer and an Akai MPC style sampling playback machine except its for video clips.
They are pretty rare so I am luckly to have scored one the last time I was in Japan.
Its a mixer, a sampler and a FX all in one.
Very useful if you have a limited amount of space.
My basic video set up usually is either a
Korg KrossFour (4 channel Mixer and effects)
and
Korg Kaptivator (sampler, effects & mixer)with cameras & the odd video synth
or a
Korg Entrancer (effects)
and
Edriol/Roland P10 (Sampler)
and
1 or 2 cameras for live feed and a video synth.
each system has its strengths and weaknesses.
The edirol P10 uses SD cards , so is easier to connect to a PC.
The Kaptivator does have a firewire connection which Ive never tested.
Combining both is a awesome way to go, though ,maybe a bit overkill ??
Anyway, the reason for this post....
I was having trouble last night getting my cameras to input a live feed into the Kaptivator.
They just wouldnt sync.
Notice the right screen is divided into 4.
The lower right corner is the video input... its blank
----------------------------
Page 14 of the manual is the important bit to read:
To select an external video source
Press the INPUT key to select one of the external video sources connected to the kaptivator.
Press the INPUT key to select one of the external video sources connected to the kaptivator.
The VIDEO INPUT indicator shows the status of the selected input.
Input 1 Lit: Currently selected
Blinking rapidly: No connection, or wrong signal format
Blinking slowly: Copy-protected signal was detected
Input 2 Lit: Currently selected
Blinking rapidly: No connection, or wrong signal format
Blinking slowly: Copy-protected signal was detected
DV Input Lit red: Currently selected (DV set to input)
Blinking rapidly: No connection
Blinking slowly: Copy-protected signal was detected
Green: Indicates that the DV connector is set to “Out”
dark (unlit) Input is off (black screen), or Main Out Capture is selected
For some reason it all works fine today.
The important thing to look for is the red lit numbers 1, 2, DV as you press that green input button
If its Blinking rapidly: No connection, or wrong signal format
You need to see a solid RED
This is how everything should work if your routing is 3 Layers
This is setting 31
This mixer setting mixes between the two clips 1st then adds the external input last.
This can be changed.
For the record,
For the record,
the cameras I've successfully used with the Kaptivator for live feeds are:
Panasonic SDR-H80
Sony HDR-XR260VE
a standard CCTV camera
PAL setting (as I'm in Australia)
The Kaptivator's input 1 is a composite.
Input 2 is S-video
I used a simple composite to S-video cable for this input as both cameras are
only composite out.

Hopefully, there will be many more nights like this.
Thanks to everyone for organising this

Cat full of Ghosts - Video Equations
These are my personal build notes for the CFOGs Video Equations synth.
Its a video synth that uses mathematics to produce the graphics.
It was designed by Robert Jordan.
The build was quite easy .. just a few hours.
Ed of Elk Elektroniks supplied all the parts so attending the workshops is a easy
way to build them.
But if you don't live close to Wollongong Australia then you can order them online.
CFOGs is based in Melbourne Australia.
+ official BOM and BUILD GUIDE:
https://github.com/cfoge/Video_EQ
https://github.com/cfoge/Video_EQ
I like to start with the lowest profile components ..
in this case the diodes
These are 5V zener diodes. There are 14 of them.
Resistors next. Start with the 100ohm ones ... there are 20 of these.
...I think this is LSD
IC headers Next
...I've installed the 5mHz Crystal and the push button switches.
The yellow components on the left are Resistor Arrays
The jacks on the right are CV inputs.
Add the 2 Caps, the power input jack & the voltage regulators
+ Voltage regulators (series)
The rear of the PCB:
Pots, & LEDs
The finished product
The 8pin IC with a "N" is the EPROM
EPROM (erasable programmable read-only memory) is programmable read-only memory (programmable ROM) that can be erased and re-used.
The KIT was supplied with two. One marked with a N, the other with a P.
N = NTSC
P= Pal
The 16 pined IC on the right is a Analog to Digital converter:
579-MCP3208CIP
The big chip in the centre is a 32-bit microcontroller
P8X32A-D40
I'm using a DC 9V supply
Centre -ve
