DIY EDU series Kick Drum module based on classical drum machines schematics
There’s nothing quite like the sound of old-school analog drum machines. Especially classic kicks like Roland’s 808 and 909 are ubiquitous in electronic music. Unfortunately, their circuitry is notoriously complex and difficult to understand. Enter the mki x es.edu DIY Kick Drum kit, which not only aims to shed some light on the fundamental circuit design principles behind those circuits – but also captures their unmistakable sound as a fully-fledged Eurorack module.
