Synthesized, analog Hi-Hats are pretty fascinating. That’s because emulating any kind of cymbal using an analog circuit is tough since the sound a real cymbal produces is not quite pure noise, but also not really harmonic. Still, a couple of classic drum machines like the Roland TR-606 and TR-808 took their best shot at it, with quite strange-sounding results that have since become iconic in electronic music. Inspired by this, we decided to follow suit and continue our percussion-focused second season of educational DIY kits with the mki x DIY Hi-Hats.

We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module. 

NB! All kits in these series are simple and come with extensive user manuals that can be downloaded separately, therefore we will not provide customer support in case your DIY build fails to function or similar.
