Archaean is one of the ancient stages of Earth's development. an era that lasted about 1.5 billion years and formed the unique landscapes of our planet. It was a time of volcanoes, primordial oceans, and the first life forms.
Waveforms of Archean are landscapes. The moon observes approaching objects. The meteorite makes noise. Weathering erodes sound. The Element shifts forms. Each mineral is a touch-sensitive key.

Archean – Open-Source Patchable Synthesizer
Archean by Nakedboards is a monophonic, semi-modular synthesizer inspired by the raw and elemental forces of early landscapes. It’s not just an expressive musical instrument - it’s an open platform for exploration, learning, and innovation.
Open-Source and Fully Customizable
Archean is a fully open-source project. Both the firmware and the circuit schematics are openly available, empowering you to:
• Modify the code to add new features or change existing ones. The firmware runs on a Teensy 4.0 and is programmable via the Arduino IDE, making it easy to experiment and develop your own functionality.
• Adapt the hardware to your needs. Since the entire schematic is open, you can replace electronic components without restrictions.
Whether you’re a developer, sound designer, or hardware enthusiast, Archean gives you complete control over the inner workings of your instrument.
Core Features
• Patchable monophonic voice, covering a wide frequency range of approximately seven octaves (16 Hz to 2093 Hz).
• Three waveform modes: randomly generated “landscapes”, smoothly evolving terrain, and classic triangle waveform.
• Built-in filter, LFO, ADSR envelope, voltage-controlled delay, and numerous patch points for extensive modulation and sound design.
• Unique 22-key touch-sensitive keyboard with mineral-shaped keys.
• Distance sensor that outputs both CV and MIDI-CC for expressive control, similar to a Theremin.
Connectivity and Integration
• Can function as a USB-MIDI controller.
• MIDI In/Out via 3.5 mm TRS.
• CV/Gate inputs and dual audio outputs (line and Eurorack-level).
Learning and Documentation
To support your experience, a series of YouTube video tutorials is available, covering everything from basic setup to advanced patching techniques. The library of educational content is actively growing to help you get the most out of Archean, whether you’re a beginner or an advanced user.
Summary
Archean is designed for creators who want more than a finished product - it’s a living, hackable platform. Open code. Open schematics. Fully reprogrammable. With documentation and growing video support, Archean gives you the freedom to build, learn, and create without limits.
