CMOS Sound Experimentation Board

A modular experiment board for hands-on exploration of sound generation using simple 4000-series CMOS logic ICs. Developed at the Karlsruhe University of Arts and Design (HfG Karlsruhe) within the Circuitry-Based Sound seminar. Unlike conventional synthesizers or DSP-based systems, the board relies entirely on discrete CMOS logic chips arranged as a patchable interface for experimental sound creation and live performance.
