This is a 12 input mono mixer with Attenuators for each input, master volume, 1/4″ outputs as well as ground connection points. Circuit was basically straight from Ray Wilson’s Ultimate Expander synth mixer.

here we have a simple digital switch array. Using two quad 4066 switches I can turn on and off signals with the pulse out from any of the sequencing modules. Again we have yellow jacks to represent the connection points … Continue reading →

two identical 4017, 8 step pulse sequencers with clock and reset inputs. two identical 4015 shift registers with clock and data inputs. one 4024 divider two 4011 based ring mod circuits one R2R ladder two 4046 VCOs based on Nicolas … Continue reading →

This is 2 individual 4040 binary ripple counters. These are clock dividers which take a clock signal in and output several different divisions of that clock. Very nice for sequencing or creating sub octaves. The circular pattern was improvised and … Continue reading →

A simple-ish envelope generator from Eric Archer. This takes a trigger signal and outputs an envelope that shapes the input signal.

This is 6 triangle LFOs or Low Frequency Oscillators built from 3, 4069 Inverter IC chips. The schematic design is Scott Gravenhorst design.

It is simply six 40106 Oscillators, with high and low range switch, coarse tuning knob, output jack and indicator LED. This module is used as mainly clock signals to drive the various other sequencers, envelope generators, and other triggerable devices. … Continue reading →
