New Erica Synths mki x es .EDU DIY Eurorack Enclosure & PSU

via Erica Synths

The mki x es. edu project takes you on a journey of building a complete, self-contained eurorack system. Those who are already into eurorack will find the mki x es. edu modules to be a nice addition to their existing systems, but those who are about to take their first steps into modular synthesizers will need a reliable and safe power supply unit (PSU) and eurorack-compatible enclosure.

We designed a DIY eurorack PSU based on a DC/DC converter that turns +12VDC from a wall wart AC/DC adapter into eurorack standard bipolar +-12V. This ensures the voltage in your eurorack system never exceeds 12V and any area in your eurorack case is safe to touch. In order to reduce the overall cost of the case we do not use eurorack rails with threaded inserts or sliding nuts, instead, there are pre-drilled, threaded holes to accommodate the modules of the mki x es. edu system in a specific order.

NB! The enclosure & PSU are designed specifically to accommodate DIY modules from mki x es. edu series and are not compatible with other eurorack modules.

We – Erica Synths and Moritz Klein – have developed 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.

In total, we have developed 9 kits to build a fully featured modular mono-synth: a sequencer, a VCO, a wavefolder, a noise/S&H module, a mixer, a VCF, an Envelope generator, a dual VCA and an output stereo mixer with a headphone amplifier. Additionally, an affordable eurorack case with a DIY PSU will also be available. While these kits are easy to build, we did not compromise on design and functionality. We will launch one kit every 4-6 weeks. Each kit comes with an extensive user manual (40+ pages) that will dive deep into not only the electronics behind each circuit, but also the fundamental principles of sound synthesis.

We hope that the mki x es. EDU project will inspire future engineers and will contribute to the ever growing diversity of electronic music technology.

Lil' Nicky (Erica Synths mki x es.edu DIY synthesizer full system)

video upload by Greg Dixon

"This is a demonstration video for the Erica Synths mki x es.edu full system. The recorded audio is completely raw mono direct from the synthesizer with no added effects etc. I built the synthesizer (which I named "Lil' Nicky") including the case with kits designed by Moritz Klein and released by Erica Synths. Lil' Nicky is patched mostly with purple 18" cables by Luigi's Modular. The purple and black look of the synthesizer/ cables as well as it's name is an homage to the pop icon, Prince."

Erica Synths Introduces EDU DIY SNARE DRUM

Designing a simple analog snare drum from scratch

video upload by Moritz Klein

"No drum machine is really complete without a punchy, snappy snare. Together with the kick, it creates the rhythmic backbone for most grooves.

So in my ongoing quest for creating a Roland-inspired modular drum machine, I knew I had to come up with a snare circuit that would complement the kick and hi-hat I‘ve already designed. After a lot of fine tuning, I landed on a circuit that can emulate a TR-606, TR-808 or TR-909 snare."

No drum machine is really complete without a punchy, snappy Snare Drum. Together with the Kick, it creates the rhythmic backbone for most grooves. So for our percussion-focused second season of educational DIY kits, we knew we had to come up with a Snare circuit that would complement the Kick and Hi-Hat we’ve already released. After a lot of fine tuning, here’s what we came up with: introducing mki x es.edu DIY Snare Drum.

Features
Manual and CV controlled Tune
Tune CV depth attenuator
Manual Attack and Decay control
Manual and CV Snappy (noise and tone crossfade) control

"While trying to fix a broken TR-909, I came up with a DIY analog FM Drum circuit that combines the punchy character of the 909 with the metallic textures of FM synthesis. It comes with four different modes:

• 909-style kick/tom
• Metallic bell/gong
• Ring mod cymbal
• FM cymbal

The FM Drum is the final drum voice in my DIY drum machine series (for now). If you want to build along, here's the bill of materials:"
