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 outputs and 2 gate outputs. The CV IN is associated...

The AI011 Analog VCO is a robust and stable analog Eurorack VCO. Using the legendary curtis 3340 IC, the Oscillator provides buffered Triangle, Square, and Ramp waveforms, as well as a triangle to sine wave shaper to provide a sine wave output. The...

This module is based on ideas presented in a 1969 IEEE paper titled - Hybrid Implementation for Sampled-data controllers. The paper presents the canonical form of a generalised digital filter made using analogue elements.....yes this is an analogue...

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...

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 capacitors. Very easy build, no special components needed...
