Serge/4U System

Handbuilt Serge/4U modular synthesizer, complemented by low level digital modules of my design. The left two panels are constructed as a single unit from aluminum enclosures that house early Serge modules built from Prism Circuits PCBs, a switching power supply, aluminum bus bar power distribution, and perfboard-constructed balanced I/O modules. Panel legends are printed paper with original Serge designs, from files provided by Prism. The right two panels follow the same scheme, with a mix of Serge and Serge-inspired modules built from CGS PCBs. Paperface graphics designed by me, inspired by Serge. The lower chassis contains a similar bus bar power system and threaded rails to mount individual modules. Modules include a Doc Sketchy Freak Shift and Hale/LW Analog Delay, re-paneled Doepfer A-110-4 and WOMS Sinulator, and CGS builds with either penciled and clear-coated blanks or Loudest Warning panels. This section also houses an attenuverting amplifier and full wave rectifier, and five digital modules designed and constructed by me on perfboard and aluminum blanks. The box on the top right is a breakout box for a Sequentix Cirklon CVIO.

Digital modules:
Unclocked 7 Bit ADC and DAC (design based on Doc Sketchy's Folding Quantizer)
7 Bit Latch built around a 74HCT373
Window Comparator with 3 bit ADC and DAC built around a CD4532 and CD4528
CD4094 based Shift Register
