This module is a dual sample & hold with voltage controlled slew for each channel. It contains a simple jerk chaos circuit running at approx. 300Hz to supply a signal for sampling. So, it is similar to the Buchla 265 Source of Uncertainty except is...

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...

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...

  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 drive is an anti-log circuit, it works a little...

The AI Synthesis Tape Echo Interface is an innovative eurorack synthesizer module that brings an undeniable warmth and character to your sound. This module is designed to replicate the classic analog tape echo effect, providing a rich and organic sound...

  NLC1088 Mogue Mixer/VCA   MOGUE is a VCA and Mixer inspired by early Moog designs, with some mods to get them into ‘Eurorack standards’ (!). Both circuits can be overdriven to get some wave-shaping action. The mixer can handle CV...

  NLC1087 Dual LPG This is a pretty standard lo-pass gate, except it uses the black box vactrol method seen in the Shat-noir Phaser and Noiro-ze VCF/VCA. DG analogue switches are used for changing between filter and gate modes.     On...

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 EN1, EN2 and EN3 VCOs along with some NLC injected in...

  circuit abbey neo mixer new from circuit abbey-- 4X4 matrix mixer The Neo Mixer is a 4-in, 4-out matrix mixer with a twist: Multiple Neo Mixers can connect together with the inputs normalled. Because the inputs are normalled you...

  NLC1022 Divine CMOS This circuit takes two input signals and divides them down by /2, /4, /8 & /16. It then XORs these divisions (XOR = Exclusive OR). All of these signals can then be mixed to create the output waveform. If this is done at...

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 it takes the concept of pinging the LPG or ringing a...
