Hello and welcome to my ultimate guide to using boolean logic gates creatively and musically for music synthesis. This video is a demo of the eas Eurorack module by Instruo but it’s also an in depth tutorial on all things logic with a “DivKid’s Logic 101” beginners guide to logic gates that ramps right through more advanced patch based problem solving.
eas is a multi channel logic module with 4 logic gates and 7 simultaneous outputs in 4HP. It also featuring some clever normalising of inputs and outputs to allow for a greater amount of varied signals from less inputs.
Logic can be such a great problem solver for a Eurorack system that I jumped at the chance to make this video a hybrid of demoing a specific Eurorack module but also making something that can serve as a tutorial for the use of logic gates anywhere you may find them, in any format. We’ll be turning basic clocks into melodies, making unique beats from simple gate sources, syncing up sloppy playing, processing audio with CMOS style ring modulation, creating possibly the greatest gated fuzz fx and plenty more. The timing index is below so you can skip around and the find the right sections to suit.
