Erica Synths - EDU DIY VCF
Product information "Erica Synths - 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.
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. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy. For build guide, more info, videos etc. please check the buttons below.

Product Safety Information
Eurorack & Desktop / Standalone DIY Kits
1. Eurorack DIY Kits
Important Notice & Intended Use
Please read this safety guide before installation or use. This kit is intended for adult users experienced in electronics and modular synthesis. Assembly, including soldering, is required. Proper testing and installation are essential to ensure safe and functional operation. The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
General Warnings
1.1. Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.
1.2. Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.
1.3. Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.
1.4. Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.
1.5. Compatibility:
• This module is designed specifically for Eurorack-compatible systems. Connecting it to non-compatible systems may result in damage or malfunction.
Assembly Requirements
• Soldering skills are required to complete the module.
• Ensure a clean, well-lit and ventilated workspace free of flammable materials during assembly.
• Use appropriate tools and safety equipment, such as eye protection.
Testing
• Test the module thoroughly for shorts or incorrect assembly before powering it in your Eurorack system. When the unit has malfunctions due to incorrect assembly, the entire Eurorack system might be damaged. It's a good idea to test it in a separate case with only that single module.
• Use a multimeter or other appropriate tools to confirm proper functionality.
Installation and Use
• Mount securely in a Eurorack case using the provided screws.
• Use only the included or manufacturer-recommended power cable.
• Connect only when the power is off.
• Follow the module's user guide for instructions on operation. Do not exceed the input/output limits specified.
