Ian Fritz/Elby Designs ChaQuO Explained by Learning Modular

Learning Modular

"This movie takes a deep dive into how the ChaQuO – a quadrature oscillator driving a “double “well” second order chaos circuit – works under the hood. I deal with the design on both a building block and actual schematic level, meaning many of the concepts and explanations can also be applied to software emulations of chaotic modulators. What we learn in the circuit-level explanation is then applied to the controls on the actual module, driving just a single synth parameter – filter cutoff – to make it easy to hear as well as see the results."

Ian Fritz/Elby Designs ChaQuO 2/2: working in multiple dimensions


"Most chaos-based modules have multiple outputs, taken at different points in their internal feedback loops. All of the outputs run at the same underlying frequency and are related in a general way, but have different waveforms present. In this movie we exploring using it to drive two and then three parameters of a 2hp Vowel vocal synthesis module, making it 'speak in tongues'…"

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."

Modular Synth - Patch in Progress 34

Published on Jul 11, 2016 isvisible / isinvisible

"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.

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!

"This is one of two custom built Metalbox Ian Fritz ChaQuO quadrature oscillator/chaos generators in Wiard 300 format.

The main function of this module is a versatile chaotic signal generator (cg). chaotic signals are signals that have varying degrees of interesting irregularity without actually becoming random. The Chaos Generator is an analog electronic simulation of the classical driven double potential-well problem, with the addition of extra gain in the circuit loop, and an extra cross-coupling path to extend the range of chaotic patterns available.

The double-well system is a "second-order" system and therefore requires an external driving signal. This is provided by the second part of the module, a sinusoidal quadrature oscillator (qo). The two parts of the module may be used together or separately. The Chaos Generator may be driven by any output of the built-in Quadrature Oscillator or by any external oscillator. The oscillator may drive the Chaos Generator or be used independently as a four phase oscillator for the usual spatial modulation and other applications. Both parts of the module are manually controlled. The Quadrature Oscillator has a frequency span of ~0.03 hz to ~3 khz in two overlapping ranges.

The module has a maximum current draw of 45ma..."

"A healthy dose of chaos for your eurorack modular!

The ED108-ChaQuO is a combination of a Chaos Generator (CG) and a Quadrature Oscillator (QO) and was designed by Ian Fritz.

The main function of this module is a versatile chaotic signal generator (CG). Chaotic signals are signals that have varying degrees of interesting irregularity without actually becoming random. This CG is an analog electronic simulation of the classical driven double potential-well problem, with the addition of extra gain in the circuit loop, and an extra cross-coupling path to extend the range of chaotic patterns available.

The double-well system is a "second-order" system and therefore requires an external driving signal. This is provided by the second part of the module, a sinusoidal Quadrature Oscillator (QO).

The two parts of the module may be used together or separately. The CG may be driven by any output of the built-in QO or by any external oscillator. The QO may drive the CG or be used independently as a four phase oscillator for the usual spatial modulation and other applications. Both parts of the module are manually controlled, to provide a compact, cost-effective unit. The QO has a frequency span of roughly 0.03 Hz to 3 kHz in two overlapping ranges.

This is a unique and complex module, we advise you to read the manual thoroughly to get the best grasp of how to use it.

The Completion

YouTube Published on May 2, 2012 by davidryle "A generative real-time recording of the modular synthesizer and Kontakt5. The synthesizers.com Q172 quantizer Aid module is sending midi pitch data back into my DAW (Steinberg's Cubase 6) and I'm routing it to Kontakt 5 with an instance of Sonic Couture's "Bowed Piano" sample sets. I also routed the midi through to the Yamaha TX816 with 8 modules playing a superb piano rendering. Days worth of patching on the modular for everything else. Some modules of note are the Ken Stone BiNTic filter/oscillator, J.Haible Tau "Pipe" phaser, Ian Fritz ChaQuO and 5 Pulser, two CGS01 sub oscillators and one CGS01 in Harmonic Sequencer mode.The HS mode is generating the pitch data for the formerly described piano patches and the high pitched sliding sounds in the background. The dotcom sequencers and STG sequencers are producing voltages for the BiNTic dark ambient industrial sounds in the background. A final white noise to the Q107 filter, Sputnik VCS, Cynthia QLPG, SSL digital delay and Oakley Deep Equinoxe phaser and STG signal amps round out the sound voices."

"Ken Stone's superb Bi-N-Tic oscillator/filter from a kit build by the Bridechamber. Not just any old filter mind you. I used an SSL/Ian Fritz Double Dekka VCO and an Oakley vco with some sequencers and envelopes to play with this demo. The only filter is the BiNTic. Plenty of external excitations from the DDVCO "A channel" and some exponential FM from an EG modified "B channel" of the Double Dekka.
The Oakley vco is sending a triangle waveform through an Ian Fritz 5 Pulser which is modulated by an Ian Fritz ChaQuO chaos generator & quadrature oscillator. It then goes to the input of the BiNTic.
Octave switching on the Double Dekka is with an STG Soundlabs voltage mini store.
The sequencers (Q119 and Q960) are timed with the SSL Tap Tempo LFO. It's multiplier is modified with one channel of the Q960 for the staggered steps.
The Oakley vco has an LFO modulation (linear FM) from an Oakley VCADSR and MultiMix. The release timing of the envelope is voltage controlled by a row of the Q960."

Yusynth Modular First Flight

YouTube Uploaded by GoldenCardiganCult on Mar 13, 2012

"This is a quick video of the maiden voyage of my DIY modular synth.

Most of the modules are Yusynth designs, but it also includes a few Paia, CGS and Ian Fritz designs.

The patch is fairly straight foward. The two randomized sequences are generated by Reaktor (via a Paia MIDI2CV). A Kurzweil Mangler is adding a small amount of Delay.

About 2:05 you will hear the second VCO frequency modulated by an Ian Fritz Chaos module.

A big thanks to all of the DIY synth community, but especially the Yusynth designer Yves Usson. His designs are brilliant and sound unbelievably good! Hopefully this video does them justice.

Thanks for watching!"

Some additional info:

"The modules are:

Yusynth
2 x VCOs
2 x Filters (Steiner and EMS)
VCA
Mixer
Balanced Modulator
Random (S&H and Noise)
LFO
ADSR

Paia MIDI2CV and Triple VCA
CGS Joystick and MFOS buffered multiples (Voltage Distribution II schematic)
Ian Fritz Chaos (ChaQuo without the quadrature LFO)"

Repose in C major

YouTube Uploaded by davidryle on Nov 19, 2011

"Slowed everything down from an earlier patch, rewire the clocking and reset the pitch voltages for an entirely different feel from the last session. Actually, much more work than just that but essentially the idea. This was not patched from scratch as usual.
A lot of fun coaxing some flittering pitches out of the MFOS quad quantizer to an oscillator sent through the Q107 filter, which was the last voice mixed into the piece. Also had fun mangling the mid tones coming from the Oakley vco with the CHaQuO. Havoc tuning never sounded so peaceful.
I plan to record about an hour of this just rolling along for a loop to sleep by but the melodic stuff will have to be randomized a bit more.
Another noteworthy thing was the use of three part chord structures from the Q960 and Q119 to six oscillators. The effort to plan each chord change was time consuming. Something close to composition (for a change)."
