Product Description
KONSTRUKT-8 is an expressive live performance instrument and sound design tool – plus a hands-on deep dive into electronic circuit design. Each of its eight DIY modules comes with a detailed build guide and can be explored on a breadboard first, letting you trace every circuit design decision before assembling the final instrument.
KONSTRUKT-8 includes four fully analog drum voices:
• Kick Drum. A resonant bridged-T network produces deep, punchy kicks.
• Snare Drum. A burst of filtered transistor noise layered over a tuned resonator creates a crisp snap.
• Hi-Hat. Six dissonant square-wave oscillators are mixed, filtered, and overdriven to create metallic percussion.
• FM Drum. Two interacting oscillators form a versatile percussion voice capable of kicks, toms, bells, and cymbal-like sounds.
A four-channel drum sequencer lets you tap in rhythms that loop automatically. Under the hood, shift registers store the pattern as a circular sequence of binary data.
All voices feed into a four-channel mixer with per-channel FX sends and a master insert, allowing you to shape the entire beat with external effects or the built-in distortion and compressor.
Two effects modules complete the system: an analog bucket-brigade delay (BBD) with flanger and delay modes, plus a diode-based compressor with sidechain capability.
What’s Included
Both versions ship with:
• EDU DIY Kick Drum kit
• EDU DIY Snare Drum kit
• EDU DIY Hi-Hat kit
• EDU DIY FM Drum kit
• EDU DIY Drum Sequencer kit
• EDU DIY Output Mixer 2 kit
• EDU DIY BBD kit
• EDU DIY Compressor kit
• 8 downloadable build guides
The system version also includes:
• Eurorack enclosure with integrated power supply
• 15 braided patch cables (5× 20cm, 5× 30cm, 5× 60cm)
Requirements
Soldering difficulty ranges from beginner to intermediate.
The build guides assume a basic understanding of electronics concepts such as voltage, current, resistance and capacitance.
For the breadboard experiments, we recommend using LABOR, our circuit design prototyping tool – a self-contained electronics playground with built-in power supply, oscilloscope, and a variety of interfacing options and controls. LABOR was used throughout the development of KONSTRUKT-8 and is best suited for experimenting with these circuits – though a standard breadboard will also work.
Completing the full learning path typically takes 6–8 weekends.
