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.”

Wavefolder plus 3 sines plus 2 VCAs

Published on Dec 20, 2018 Randy Piscione

“Experimenting with different ways of generating timbres for a custom Eurorack panel I’m working on with PM Foundations. I took a sine into a mixer, and two more sines into two VCAs, and then those two also went to the mixer. The output of the mixer went to an nlc Timbre. I also ran an LFO into each of the VCAs.

The Timbre is the first version, so I

Vectrex vector CRT vs modular synth

Published on Nov 17, 2018 Jason Hotchkiss

“Playing with a vector CRT from a Vectrex game console using eurorack synth modules to drive the X/Y/Z lines. This just blows me away – I could keep staring at this all night!

Just a random first time jam with it so not much thought went into patching but used Befaco and Roland VCOs, Intellij uFold wave shaper, Hexinverter mutant bassdrum triggered by

CMS Goes Eurorack with the CMS 1004 (ARP 2500) – Pearlman Oscillator and T-mixer

“This is a quick preliminary demo of the new CMS 1004 Pearlman Oscillator. This VCO is a faithful reproduction of the massive VCO circuit from the ARP 2500, shrunk down to euro rack format. An analog CRT oscilloscope shows
