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 that produces deep, punchy kicks.

• Snare Drum. A burst of filtered transistor noise layered over a tuned resonator creates a crisp snappy snare.

• 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.

Build Guides

Kick Drum | Snare Drum | Output Mixer | Hi-Hat | Compressor | FM Drum | BBD | Drum Sequencer

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.
