Nonlinearcircuits (NLC)

This 8hp Eurorack module is a squid brain cell simulator!The Squid Axon is a circuit based on the Hodgkin-Huxley equation describing the chaotic behaviour observed in giant squid axons. The...

This timbre generator is basically a clone of the Buchla timbre found in the Easel. I have added a simple tri2sine converter input, along with the regular input, and buffered output. The panel looks...

  NLC1057 Triad Triple EG These are AR or AD generators that will fire on a trigger or a gate, giving envelopes up to approx 25 seconds. A single gate to input 1 will fire all 3 envelopes, when...

Full kits include everything you need to build the module. This is a simple circuit that is capable of making a wide variety of sounds. With a sequencer it can be used as a crude VCO, but fed other...

  NLC1062 Bindubba Sequencer v3 PCB This is a new release of the bindubba3 sequencer which was originally released in March 2010, thouh there have been a few changes since that version. The...

  NLC1064 Divide & Conquer   This is a clock divider module containing 4 different dividers: /2, /4, /8, /16, /32, /64, /128, /256/1.5, /3/2.5, /5/3.5, /7 All sections will run off a...

  NLC1065 Sly Grogan   SLY GROGAN is an envelope generator based on the design in Electronotes #86. It can produce a wide variety of different envelopes and bursts, perhaps most interesting...

Another great module from nonlinear circuits! Primal Hyperchaos is based on the description in a paper by C Li, et al. It can be built to run at different speeds simply by installing different...

Hyperchaos Deluxe is based on the description in A UNIQUE SIGNUM SWITCH FOR CHAOS AND HYPERCHAOS by C. Li et al and is an expansion of the circuit used in Primal Hyperchaos. There are 10 different CV...

This VCO uses DG202 (or equivalents) analogue switches to achieve the thru 0 function, based on ideas presented in Electronotes EN#75.   Documentation Demo     On Demand...

  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...

This is based on the Korg PS3100 resonator circuit, except there are 4 BP stages instead of 3, it has a feedback path, the CV control section is totally different, the filter core components are...

This is 8 different rectifiers processing 4 input signals. It is happy to work with audio or CV or both at the same time. It has 16 outputs that will deliver 16 different signals made up of...

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...

This is a 1 to 8 multiplexor….or multiplexer if you prefer….with a thru and hold circuit attached to each output. the active output is chosen by whichever combination of the x00, 0x0...

This VCO was mainly designed as an upgrade for the dual OTA VCO. It is a traditional triangle core VCO with a built in VCA for the FM control section. The design draws on sections of the Electronotes...

  NLC1075 Lo Pass Gate v5   Full kit for the Nonlinearcircuits Lo Pass Gate, with the v5 PCB. All parts are bagged and labelled-- kit supplied with black knobs and 3pdt on-on switch per...

  NLC1077 Shat-noir Phaser   The core of the Shat-noir phaser is based on classic LDR based phaser designs, notably the Carlin, Compact Phasing A, Morely Phaser and ADA final Phase. The CV...

  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...

  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,...

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...

  NLC1082 Noiro-ze   This module uses the same blackbox technique as the Shat-noir Phaser.The VCF is based on the Steiner diode VCF but this one uses LDRs rather than diodes and a CV...

  NLC1083 Big Room   This module merges the Polyfusion reverb driver circuit with the NLC Segue for VC panning between wet and dry signals. It also has a VC feedback circuit....be careful...

This module is based on ideas presented in Electronotes #132. It is a VCF with a 'filter exciter' section to allow a wide variety of acoustic, semi-acoustic and not-acoustic-at-all sounds. In a sense...
