Details on the Elby Designs Chaotica by Ian Fritz

This one in via Dimitry on The MATRIXSYNTH Lounge. Modularsynth.ru has a post up here on the Elby Designs Chaotica.

"Ian Fritz is known as developer of electronic circuits which utilise the Chaos Theory. One of these circuits that is called Chaotica, can be purchased from Elby Designs as assembled Eurorack module Panther ED120 or as DIY kit. The Chaotica is a third-order chaotic system with extensive voltage control...

It’s hard to understand the way it works without oscilloscope, but mainly, Chaotica imitates the process that can be imagined as some kind of particle moving in a 3-dimensional space. Three variables, x, y and z keep the coordinates of this particle. oscilloscopeThere is also vectorized time variable that can be reset and can flow at various speed. After reset, this “particle” always appears at the same point and starts to move in complex elliptic trajectories. The full path is completely determined by system parameters and can by repeated, but if some of the parameters changes even slightly, the path can change almost unpredictable..."

Serge - Ian Fritz DoubleDeka as a Trigger Sequencer

Published on Jun 17, 2016 isvisible / isinvisible

"Here's a video of a two panel Serge system comprising of two Ian Fritz panels. A Timbre Tantrum and a Chaos Theory.
The DoubleDeka VCO is acting as a trigger sequencer. It's triggering the following:
Bank A:
1. One side of a dual TGTSH (fed by the Chaotica)
2. A Teezer TZVCO
3. 4X4 AD/AR
4. Threeler VCF
5. Mixer

Bank B:
1. One side of a dual TGTSH (fed by the Chaotica)
2. A Teezer TZVCO (this one needs calibrating)
3. 4X4 AD/AR
4. One side of a Dual 2Q/4Q Multiplier
5. Mixer

Both banks mixed together and fed through a Bandive Accessit stereo spring reverb.

The second TZVCO (Teezer) needs calibrating, so sounds a bit off higher up the scale.

Cheers"

Chaotica as an Audio Source

YouTube Published on May 7, 2012 by MongoSynth

"This video shows Ian Fritz' Chaotica module being used as an audio source. The patch uses the X and Y outputs as audio streams (they also drive the o'scope) and the Z is used with DUSG to generate an envelope of sorts. The rate control is fairly high (hence the audio output). A pair of LFOs are driving the rate and gain. In addition I periodically twiddle the knobs. The volume is low at some points and but quite loud at others, so be careful...."

Laser Chaos

Published on Jul 25, 2013 pirxmodular·3 videos

"Chaotica is a third order analog chaos circuit with voltage control over many parameters, designed by Ian Fritz.

This video only scratches the surface of the circuit capabilities. I was manually tweaking the circuit parameters in order to generate various chaotic patterns. X-Y outputs of the circuit are connected to a DIY laser projector. The sound comes from the Chaotica Z output and is processed by Neural Agonizer spring reverb.

Beware of your speaker levels - the recording covers a wide frequency range."

"Make your patches evolve with chaos!

The ED120 is a multi-featured, autonomous, third-order chaos circuit with the following functions:

A third order system with a total of four nonlinear elements in the circuit path to provide a wide range of chaotic signals.

Exponential voltage control of rate (frequency) over a wide range, from creeping sub-audio rates to well up into the kHz audio range. Linear voltage control of loop damping, gain and offset. Many interesting sweep and modulation effects are enabled by these control inputs.

A Reset/Inhibit input which allows the system to be set to zero voltage at all three integration stages. This has many interesting uses. For example, the chaos path's evolution can be followed by varying the rate of a series of reset pulses. By limiting the range of an attractor's evolution, one can produce interesting and complex periodic waveforms.

Voltage outputs for all three system variables, X, Y, and Z.

Tech, No Enfermo & Filter Spank

Published on Jul 14, 2014 paulstodawall

"This recording was made using one each of the first two Ian Fritz 4U modular synthesizer panels. These panels are 100% Serge-compatible, but make a great little system on their own!

Other than some minimal EQ and level adjustments, this was recorded with no external effects or controllers.

I don't often take good patch notes, but I will try to briefly describe the basic patch idea. I like trying to make groove-based multitimbral tracks using smaller modulars, so that was the idea with this recording.

I am using the ChaQuO as the master clock in this patch. Since there are comparator inputs on the 4x4 and All-In envelope generators and the TGTSH S&H modules, the smooth, wiggly chaos outputs can be used for timing purposes.

The two drum sounds are the Teezer VCOs. Both are fairly simple pretty drum patches. The bass drum is the raw sine output, while the triangle output of the other Teezer is being processed by the Wavolver II waveshaper for the second percussion sound.

The bass line is the DoubleDeka graphic VCO being run through the Teezer VCF.

I may have been using the Chaotica for audio-rate modulation at some point as well.

There is a lot of flexibility using this two panels system!

Modulation: Periodic vs Random vs Chaotic

Published on May 22, 2020 Learning Modular

"What are the differences between periodic modulation (i.e. a normal LFO), a random CV source, and a chaotic CV source? Some may be surprised to learn that the chaotic source is actually a cross between a random source and a normal LFO: its output can be fairly consistent for a few cycles like an LFO, but then it will create its own variations on the theme. In this introductory video I demonstrate these differences, both controlling a filter cutoff (one dimension) and the two timbre parameters of a 2hp Vowel oscillator (two dimensions).

If you would like to dive deeper, I’ve created a pair of companion posts for my Patreon supporters. The first (https://www.patreon.com/posts/37383127) goes into more detail comparing these three types of modulators, including patch and application suggestions; the second (https://www.patreon.com/posts/37424894) goes deeper into explaining chaos theory and some common characteristics of chaotic CV sources.

I am also creating videos on Ian Fritz’s ChaQuO, Chaotica, and Hypster modules that will be made available to +5v and above Patrons, as well as those enrolled in the Eurorack Expansion: Extended (Tier 3) course on https://courses.learningmodular.com."

Luminous Trilogy & A CATALOGUE OF FM MATERIALS by Element433 ( a.k.a. Pere Villez)

via Element433 (Pere Villez)

"When I made the popular YouTube series 'FM Catalogue of Materials', many viewers commented that they would love to see some more of the 'music tech as cinema' style created in the videos.

My new project 'Luminous Trilogy' release, does exactly that. In part 1 'WTD', synths and synth technical diagrams, together with Pure Data/Max patches, become casual parts of the film's environment, which is set in an alt near future. Part 1 was realised with analogue modular, whereas Part 2 "Breath" was scored using binaural audio, VCV rack and live Indian tablas. Part 3 'Contrails' uses physical models, Samplicity's Berlin Studios and vintage FM hardware."

Update: Element433 has made the VCV patch and assets used in the film "Breath" below a free download. You can find instructions on downloading the patch and setting it up here: http://tinyurl.com/e433WpBrvcv.

Walking The Dulzaina - Luminous Trilogy - Part 1

Walking The Dulzaina is an edited one-shot music film which details the manic walkthrough time-lapse of an imaginary synthesised dulzaina (Spanish folkloric instrument) being taken for a walk through the "Las Vegas" like dressed streets of a small village festive celebration set somewhere in the near future.

The visuals are nods to the Bladerunner, Lynch, Weirdcore and Kubrick where the glow of transparent neon CRTs, display technical diagrams with a music technology theme. Some suddenly slide up from the ground, while others cross from one side of the street to another.

The music is inspired by minimalism, industrial techno synth-folk where Steve Reich and Techno meet Raymond Scott and 1960's BBC radiophonic.

Musical Equipment Detail:

Intro: Moog Subharmonicon through Fairfield Randy's Revenge ring modular - into two crunchy Elby Systems stereo valve preamps and out into a stereo pair of Doepfer A-199 spring tanks).

Dulzainas: Buchla Easel Command sometimes untreated and sometimes solo through a J.H. 'Son of a Storm Tide' stereo analogue studio flanger (built by Van Daal Electronics (second dulzainas and very low transition whoooses). Buchla and Subharmonicon sync locked and clock divided by Ornaments and Crime clock divider.

Final wormhole sequence: Subharmonicon through stereo A-199 Doepfer spring reverbs and Paulstretched.

This work is not sponsored by any the manufacturers mentioned. They are personally purchased pieces of equipment.

"Elby eurorack system using mostly Serge licensed replica modules (and a Doefper A-110-4!). All modules include banana jacks or have been slightly modified (i.e. not irreversbly; a single contact was moved on the jacks of the VCS, Chaotica, and A-110-4—connectors fit quite nice and snug) to permit banana jacks. Lightly used otherwise, most modules bought direct from Elby. Powered wooden case by Dutch Modular SynthLabs. This is a full complete system designed to exhibit the most functionally-dense, multidimensional Serge modules (which only banana jacks can really exploit—e.g. system can be programmed for the availability of seven different audio-rate VCOs) into the portable, travel-friendly 6U 2x84hp eurorack format. Also includes DIY 0V ground jack attached to power bus which allows interfacing with external equipment."

"My Ian Fritz panels (Serge) playing very nicely with my Eurorack set-up.

The AFG is clocking the Pithoprakta, which in turn is triggering everything else.
Elements - Bass
Rings - Processing audio from the Radio Music
AFG - low clicky audio processed by the ADDAC Fixed Filter Bank, which has each frequency being modulated by various Ian Fritz designed modules (Chaotica, ChaQuo and Jerkster)
Serge Modular (Ian Fritz - Chaos Theory and Timbre Tantrum panels) - Plinky plonky piano sounds, warbles and atmosphere.

Cheers"

This one make me think of what John Carpenter might sound like exploring modular. Very Carpenter-esque. Love it.
