Erica Synths Introduces DIY Drum Machine

Erica Synths says that 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.
