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).



Society City is a place for conscious creativity. 
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


Terry's video rig

Love seeing the module. esp with the Ukranian Trident. Slava Ukraini. Glory to the Heroes.

Roland RS 202 - internal pics

 I recently purchased a Roland RS 202 on line.
Wasn't sure if it was even working.


This synth was made in 1976. The older brother to the RS-101 (a commercial flop).
The 202 has a vibrato & Ensemble/chorus..... the precursor to the famous "Juno effect".

These are still reasonably priced. 
Its fully polyphonic, That is all 61 keys can be played simultaneously.


There are 3 sound presets:
String 1 (low cello & bass)
String 2 (higher pitch -- Viola / Violin)
Brass


These are some pics of the internals.


All those hand wired looms.

Tone control & Filter (FL-6A) board (above)




Power supply board is to the extreme left.
Modulator board (ET-8A) in the middle
Tone generator & gate circuit (AGH-2B)to the extreme right


Below is the Tone generator and gate circuit board.
It connects to the keyboard.
The ICs are LM3216 (x10)
TC4001
The big IC in the centre is a LM8071

Close up of the Modulator board
The 3 ICS are Panasonic MN3002 chips.
These are BBD chips for the Chorus ensemble

PSU


Lovely to see these handmade / soldered boards.
They sure don't make them like this anymore.

Elk Eletronics meeting tonight



Welcome to Electric City! Special thanks to our new hosts Society City and Barley Grass Bar in Wollongong.
We are excited to bring you an immersive lineup of electronic music and projected artworks exploring the theme of Hadopelagic - Deep Under the Ocean.
We will have an opportunity for a collecting modular jam, so if you have a portable modular synthesizer, please feel free to bring that along to join in the jam at the end of the night.
Entry is Free with food and drinks available from the Barley Grass Bar.

Creating a Melodic Soundscape From Scratch on Freaq FM

..

Looks great.
There is a DIY kit available

Freaq FM 8-bit Digital FM Generative Synthesizer
2 independent FM voices each with user-controllable waveform, modulation envelope and LFO, integrated with a 16-step generative sequencer.



  .

2 independent 8-bit FM voices
2-operator FM (for old-school prince of persia vibes!)
Multi-mode FM ratios - quantised, free-multiple, independent
Multiple operator waveforms for carrier & modulator - Sine, Triangle, Overdriven triangle, Saw, Square, Noise, Off
Attack/Decay modulation envelope per voice
LFO per voice with multiple waveforms and configurable destination: modulation envelope (attack, decay or depth), FM ratio, note length

2/1.5 track polymetric sequencer with up to 16 steps per track (Both tracks use same note sequence but can have different step-counts for poly-metric rhythms)
Multiple generative algorithms - (semi)random notes, (semi)random runs, arpeggio, drone
Sequence mutates/evolves at user-defined rate & note-density
Selectable tonic, octave & scale - Ionian (Major), Minor (Dorian), Pentatonic, Phrygian (GOA!), Octaves, Fifths

VC ADSR - NLC build notes - part 2

Some build notes for the Nonlinear circuits VC ADSR.
The attack, decay & release stages are voltage controllable.
(not sustain).

This is part 2 on my build.

WIKI


I'm up to building a light proof box to house some LDRs and LEDs.
These make a diy vactrol circuit.

This is a super  simple module that uses a 555 timer, op-amps and some diodes to make 
a ADSR envelope generator.

It's based on the classic Jacky/Kirschman 555 ADSR circuit from 1980.
Andrew has replaced the Attack-Decay-Release pots with DIY vactrols.
The 555 controls the sequencing while the diodes switch the currents.

This is the box so far:

time to solder the LDRs / LEDs

1 x 10K linear pot. (type B)
6 x 100K linear pot

One of my favourite movies.
I think (like most of the men of my generation), Grace Kelly was my first love.
