  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...

This is the SMT Euroroack version of Ray Wilson’s AR ENV module. ​ Gated mode provides classic AR response. Triggered mode provides AD response. Retriggerable as soon as the attack cycle completes. Attack and release times from 1 mS to 20 seconds...

  AI Synthesis AI006 Eurorack Stomp Box Adapter The AI006 Eurorack Stomp box Adapter is an updated take on a classic utility circuit that converts the higher signal levels of a modular system to be converted to the lower level signals that most...

  NLC1078 Bi-Di Dual Choppers   This is a dual stripped version of the original Chopper. It is a very easy build with few components. It can sort of be used as a 1 into 2 switch or 2 into 1. A CV signal can be used to help control the switching...
