Looking like mess of wires and knobs and resembling something Shady Tel might be familiar with, modular synthesizers stand at the intersection of art and technology. Individual modules follow the Unix philosophy of combining small tools that do one thing well. By connecting these modules in any of millions of different combinations, musicians create their own custom instruments capable of almost any sound imaginable. In this talk, the audience will get an introduction to modular synthesizers with the popular Eurorack format. Through a live demonstration of the author’s Eurorack system we’ll discuss the basic building blocks, introduce and walk through the classic “East Coast” subtractive synthesis style, and build up to some banging techno.
