nonlinearcircuits SPASM - LDR controlled (!) chaos

"This module takes the classic Sprott jerk circuit and replaces all the resistors with LDRs.....a 7 way vactrol."

"This module takes the classic Sprott jerk circuit and replaces all the resistors with LDRs.....a 7 way vactrol. This means the brightness of the LED in the giant vactrol controls the frequency of the circuit.

It is a very easy build and will give you a very flexible chaotic circuit. The CV inject jack allows you to control the chaos with gates and CV, some signals will cause it to pause or stall, others will make it glitch & freak out. CV freq controls the LED which, in turn, controls the resistance in the LDRs.

It is a very flexible build; you can use any LDRs you like, so long as they are the same. You can also use any capacitors you like for CAP, so long as they are the same.

Of course, the LDRs and capacitors you choose will affect the behaviour & frequency range of the circuit. GL5516 LDRs go to 500kΩ off resistance whereas GL5549 go to 10MΩ+ (anywhere from 10MΩ to 20MΩ), so will be a lot slower but will give a much wider frequency range and some very unpredictable outputs. Similarly with capacitors 10uF will be a lot slower than 10nF.

If going for the more extremely slow values, GL5549 LDRs and 10uF caps, the module will stall at minimum pot settings and generally needs a CV on the CV freq input to make it operate. This is actually a good thing as you can turn the signals on and off with CV or gates.

Volca jam for Jamuary 2019: day 3 (Abel)

Published on Jan 4, 2019 Slenterende Beer

"'Jamuary' is a yearly event where people upload short music jams every day throughout the month of January. This submission is for January 3rd, by Abel.

We're huge Tycho fans, and this jam is clearly inspired by their music.

Korg Volca Sample + Korg Monotron Delay
Korg Volca Keys + Zoom MS-50G
Korg Volca FM + Source Audio Ventris
Korg Volca Bass + Chase Bliss Audio Thermae + GFI System Specular Reverb V2
Arturia Beatstep Pro
Arturia Keystep
Miditech MIDI Thru/Filter
Mixer: Behringer XENYX UFX1204
Power: Strymon Zuma

Video recorded with iPhone 7. Audio recorded with UFX1204 in "standalone" mode, recording directly to USB HDD.
If you have questions about how everything (Volcas, effects, controllers) is connected (power, audio, MIDI), check out this video: https://youtu.be/lGTxhh5q1W4

nonlinearcircuits Signum Hyperchaos 1

Published on Jan 4, 2019 cirtcele

"This is an expansion of Primal Hyperchaos, based on the description in a paper by C Li, et al. The internal signum switch has been brought out to the panel. It can be used as a stand-alone switch (don’t expect it to be clean and nice) or it can be used to inject signals into the hyperchaos circuit or control the switching of the hyperchaos."

See this post from 2017 for additional details.

nonlinearcircuits GENiE 1 - GEneralized Nonlinear Extrapolator

Published on Jan 4, 2019

"This module is made of 3 neuron circuits and a difference rectifier."

"GEneralized Nonlinear Extrapolator

This module is made of 3 neuron circuits and a difference rectifier. The neuron outputs are fed to the switching pins of the next neuron’s attenuated input; 1>2, 2>3, 3>1. This means the circuit will work with a single input signal, delivering all kinds of mayhem at the outputs.

There are also 4 shared inputs so that the same signals can be fed to neurons 1&2 and neurons 2&3. The Difference Rectifier compares the outputs of neurons 1&3 to the output of neuron 2. If you want to use the neurons individually then turn down the input pots or use the upper neuron specific inputs to disconnect the signals coming from its neighbour.

Just like a set of synaptically connected neurons, this module is noisy and unruly. It is never going to learn anything it lives in and for the moment. It can be used to process audio, CV or audio and CV……do whatever you like to it.

The name is from the computer described in the 1964 Keith Laumer novel – The Great Time Machine Hoax, although this module differs in ability (can’t time travel or get married ….. afaik), the name is quite suitable.
