Logic in Eurorack with EAS from INSTRUO

Everything you need to know about logic in Eurorack with EAS from INSTRUO

"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."

Logic gates were originally used for the implementation of Boolean functions in computation and in electronic devices. These functions were performed on one or more binary inputs to create a single binary output.

In music synthesis, this concept can be appropriated for many things including the creation of interesting rhythmic patterns as well as patch-based problem solving.

eãs is the be all and end all of logic modules. Sporting all of the classic logic gate functions, it includes AND, NAND, OR, NOR, XOR, XNOR, and NOT.

Everything from syncopated rhythmic structures, to CMOS-style ring modulation, to creative solutions to your patch’s most glaring issues, eãs is there.

Logic, after all, is the beginning of wisdom, not the end of it.

eãs | noun (nature) a cascade of water falling from a height, formed when a river or stream flows over a precipice or steep incline."
