mki x es.EDU DIY System
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.
EDU DIY Wavefolder
Even though wavefolding is more of a west coast synthesis concept, it’s a great addition to the otherwise very east coast mki x es.edu DIY system. Why? Because it can provide a ton of unusual timbres for your patches: from a slight dash of brightness to harsh metallic drones. That’s why we came up with this super simple BJT-based double wavefolder.
LXR Drum Module
LXR eurorack module is a compact and great-sounding percussion synthesizer based on the sound engine of the LXR-02 drum machine. While retaining the core interface of the LXR-02, this module adds the essential eurorack ingredient - assignable CV control over parameters and many more tweaks in the user interface for better integration in any eurorack system.
EDU DIY Output
The mki x es.edu Output Mixer is essentially a panning mixer – it takes two mono inputs with adjustable gain and pans them left or right to the stereo output, and an integrated amplifier boosts the signal for use for headphones.
EDU DIY Noise/S&H
Whether you use it for self-sequencing, for adding a dash of randomness to your filter movements, or for rough analog bitcrushing, a sample & hold-circuit can often be the secret sauce that takes your patch from decent to distinctive. That’s why we came up with this super simple JFET-based implementation – and then upgraded it with a couple of extra features like an internal clock generator or a dedicated slew output. Of course, we’ll need an interesting input to sample – which is why you’ll often find sample & hold modules with an integrated noise generator. So we’ll do the same! But instead of just one noise color, we’ll throw in two extra: pink and blue in addition to the standard white noise.
PĒRKONS HD-01 is a unique live performance and sound design instrument that tears down the borders between drum machine, synthesizer, and drone instrument.
EDU DIY Mixer
Mixing might be more of a utility function in a modular synthesizer – but this doesn’t necessarily mean it has to be dull and boring. Case in point: this super simple three-channel mixer with built-in diode distortion will make your patches sound delightfully rough.
EDU DIY VCF
Who doesn’t love a good resonant low pass VCF? It’s arguably the beating heart of any subtractive synth – adding character, dynamics, and a good deal of retro-futuristic oddness to your patches. That’s why a diode ladder VCF that sticks to super basic and widely available components was created. On top of that, the architecture is as approachable as possible by avoiding the tricky diff-pair setup classic ladder filters rely on.
Black 3109 VCF/VCA
The Erica Synths Black 3109 VCF/VCA is a lowpass filter and voltage-controlled amplifier combo built around the AS3109 VCF integrated circuit, a contemporary version of the IR3109 chip, found on vintage Roland synths such as the Jupiter series, Juno series and the SH-101.
Black Multimode VCF B-stock
Erica Synths Black Multimode VCF has simultaneous HP, BP and LP outputs and CV control over cutoff and resonance for serious modular patches. B- stock consists of items from demo systems and items sent back from our customers. They may be used therefore they may have some minor visual defects, however all modules are fully tested and in perfect working condition. We also give 1 year warranty to all our B-stock products.
DIY Modulator B-stock
Erica Synths DIY Modulator is 35mm deep, skiff friendly, has solid mechanical construction and doesn’t require wiring. This is already assembled module. B- stock consists of items from demo systems and items sent back from our customers. They may be used therefore they may have some minor visual defects, however all modules are fully tested and in perfect working condition. We also give 1 year warranty to all our B-stock products.
Drum Modulator B-stock
Erica Synths Modulator is an advanced modulation and pitched noise source with focus on rhythmic (but not limited to) compositions in mind. It features two identical syncable to the BPM LFOs/noise sources with selectable morphing waveshapes. LFO frequency can be manually adjustable, as well as they provide frequency divisions and multiplication in Sync mode. Each LFO has two outputs- main one and secondary one with adjustable phase, so you can create evolving modulations. Furthermore, LFOs can be linked to work at the same frequency and the first LFO has built in VCA to control output signal amplitude. B- stock consists of items from demo systems and items sent back from our customers. They may be used therefore they may have some minor visual defects, however all modules are fully tested and in perfect working condition. We also give 1 year warranty to all our B-stock products.
