Whether you’re looking to beef up your basslines, add sustain to your leads, or tame the peaks of your percussion, this circuit’s got you covered.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 which can be downloaded separately, therefore we will not provide customer support in case your DIY build fails to function or similar.DIY-Kit-Type:THT-Kit-1.

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.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.In total, we have developed 9 kits to build a fully-featured modular monosynth: 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. For each kit, there is an extensive user manual (40+ pages; can be downloaded separately) 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.DIY-Kit-Type:THT-Kit-1.

Lazer Phazer it's at his core 2xSystem7xx phaser with a lot of addons.It can work as a stereo phaser, as a mono BI-Phaser, as two totally independent phasers, or as a 16stages phaser in series mode. Thath's not all, the LFOs of the phasers can work idendepently or linked. In inverted mode for stereo phase galore. The feedback can be modulated by internal LFOs, external CVs or both of them in the same time.Kits have 16 x 2SK30A fet transistors matched and selected from new old stock, so the retro sound it's totally there.This module is a collaboration between Feedback Modules and CMS-LAB.DIY-Kit-Type:THT-Kit-1.

This module is the result of almost a year of brainstorming to make a multipurpose sound destruction module.After checking several classic distortion/fuzz/overdrive/clipping circuits, we decided to blend several ideas in one module and give you enough options, so you can mangle your sound to your taste.The circuit blends direct clean sound with two different type of distortions.One circuit is a FET preamp based on a classic circuit of a mini portable cassette recorder & mixer combo from the eighties. It has variable gain and level control.The other circuit is based on classic guitar pedal distortion/fuzz with switchable diode or MOSFET distortion. This circuit also has variable gain and level control.The two distortion circuits are followed by a Baxandall two band equaliser (the one from our PRE-KM module) to shape the distorted sound to your pleasure.Finally the mangled (double distorted/clipped equalised) sound is blended with the clean sound for the right balance.This module sounds great on drums, bass synth or even acoustic sources. Enjoy your new sound shaping toy.On the technical side we took great care for the PCB design and although this is an SMD circuit board we decided to use through hole parts where we considered it matters (some capacitors and the FETs).DIY-Kit-Type:SMD-Kit-2.

As the name suggests this module can produce sub frequencies of -1 and -2 octaves relative to the square wave signal provided at the input jack.But this is not just a simple SUB generator. It also has a little mixer that will let you add different levels of -1 and -2 octave signals to the original square wave. You can select the -2 octave signal to be a square wave or a pulse wave.The module has individual outputs for the mixed signal, the -1 octave and the -2 octave.DIY-Kit-Type:THT-Kit-1.

Allpass VCF. Continuum looks and acts rather like a VCF, in fact that is exactly what a phaser is, an all-pass VCF. There is far more to phasers than just sweeps up and down from an LFO, so Continuum has two CV inputs, so you can use a variety of CV sources simultaneously.DIY-Kit-Type:THT-Kit-1.

Meth Amp is based around the fuzz core of the EH Big Muff pedal. Lovely fuzz and distortion based on the classic Big Muff pedal! It’ll do wooly warm fuzz, subtle tone shaping with a soft saturation/colour, feedback madness and work as a great output VCA (LPG style tones possibly too). The clipping diodes have been replaced by red LEDs to take account of the change in power supply from 9V in the original Big Muff to +/-12V in Meth Amp.To the fuzz core has been added a bunch of OTAs, each controlling a different aspect of audio processing: gain, regen (a new feature - not present in Big Muff), tone and volume. Thereby, each feature is fully voltage controllable.Additionally, there is a separate x100 preamp which can be used to boost external audio for further processing by Meth Amp.

ThermoNuclear is a sub-miniature vacuum tube based overdrive. The first stage is a MOSFET with switchable mu-amp. The second stage is a self biased sub-miniature pentode with switchable triode/pentode. Then there’s a tonestack based on the EH Big Muff. Finally, there’s a blend control and another MOSFET stage for some gain recovery after the tonestack. ThermoNuclear will crush and destroy your tone with a pleasing warm tubey goodness.Although the filament of the tube will glow, it’s not a lightbulb, and the level of glow may vary between different tubes.DIY-Kit-Type:THT-Kit-1.

GETREKT is a full analogue waveshaper - an aggressive one. Disrupt and Pieces are analog touch controls; they act like potentiometers and they keep the value once the finger is lifted from the surface.DISRUPT: controls how much the output is affected by the waveshaper circuit. At maximum it will fold and create a total harmonic distortion.PIECES: the pulse width of the resulting transformed wave.Both parameters have a dedicated reactive CV input. If connected, the touch potentiometer act as an offset of the incoming signal.The circuit is designed to invert the polarity of any given input.Features:• Clipping and folding analog waveshaper circuit.• Touch Controls on the amount of effect and PWM.• Reactive CV inputs on both parameters.• Inverts the polarity of any given input.• Works with audio and CV sources.• Single board design - extremely skiff friendly.• “Whatever” power connector a.k.a. don’t mind the polarity.DIY-Kit-Type:SMD-Kit-1.
