This is another somewhat lazy design, but a nice easy build.. Basically grabbed the NLC Triad and replaced the pots for Attack & Decay with vactrols Not sure why it hasn’t been done before, it is a simple circuit and the results are fun; lots...

  NLC1069 Timbre & Timbre   This is simply a dual version of the Timbre!, which was based on the Buchla circuit. It is all smd (the single version is thru-hole) and the tri2sin circuit has been dropped, there is an input attenuator for each...

  NLC1080 Genie   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...

The AI010 Switching Attenuator is a 2hp dual passive attenuator with switched jacks that allow the attenuator to also work as a multiple. The top-most input is normaled to the second attenuator knob and the third attenuator input. Control voltage is a...

This is Ian's introduction in his article on the circuit: The Hypster is an electronic fourth-order hyperchaos generator for use in modular electronic music systems.  Hyperchaos is chaos on steroids, with the mathematical divergences being generated...

The AI Synthesis AI008 Eurorack Matrix Mixer is a 4 input, 4 output Eurorack Matrix Mixer. The mixer is buffered and DC coupled, so that it can be used to mix both Audio and CV signals to multiple outputs, or at the combined output. Use the Eurorack...

The NLC Mobius PiLL is a chaotic noise module. There are several papers describing ways to couple PLL (phase locked loop) ICs to create chaos. I have been sitting on a stack of them for years but found the actual circuits quite limited in...
