Eight modules, assembled by hand, form a complete percussion instrument and sound design tool — while each module simultaneously functions as a course in analog circuit design. This is not just a soldering kit. It is a structured learning path that ends with a working, patchable, fully modular drum machine.\u003c\/p\u003e   \u003ch3\u003eFour Fully Analog Voices and the Logic of Modularity\u003c\/h3\u003e   \u003cp\u003eThe system's core is four percussion voices: a Kick Drum built on a resonant bridged-T network for deep, punchy low end; a Snare Drum combining filtered transistor noise with a tuned resonator for a crisp snap; a Hi-Hat running six dissonant square-wave oscillators through mixing, filtering and overdriving for metallic character; and an FM Drum pairing two interacting oscillators into a voice capable of kicks, toms, bells, ring-mod cymbals, and more. Every module can be explored on a breadboard before final assembly, letting you trace each circuit design decision at the component level before committing to the build.\u003c\/p\u003e   \u003cp\u003eThe four-channel drum sequencer uses shift registers to store patterns as a circular sequence of binary data — rhythms are tapped in live and loop automatically. A four-channel Output Mixer 2 with per-channel FX sends and a master insert closes the signal chain, with a built-in drive circuit for on-board distortion without external patching.\u003c\/p\u003e   \u003ch3\u003eBBD, Compressor, and a System That Grows With You\u003c\/h3\u003e   \u003cp\u003eTwo effects modules round out the system: an analog bucket-brigade delay with flanger and delay modes, and a diode-based compressor with sidechain input. Both work as mixer master inserts or as per-channel send effects. Erica Synths rates the build complexity as intermediate, with a full learning path — breadboard exploration, circuit theory, module assembly — estimated at 6–8 weekends. All finished modules are standard Eurorack-compatible and can be moved into a larger system whenever KONSTRUKT-8's eight slots prove limiting.\u003c\/p\u003e   \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e   \u003cul\u003e     \u003cli\u003e8 Eurorack DIY modules: 4 drum voices + sequencer + mixer + BBD + compressor\u003c\/li\u003e     \u003cli\u003eKick Drum: bridged-T resonant network, deep punchy analog bass\u003c\/li\u003e     \u003cli\u003eSnare Drum: filtered transistor noise layered over tuned resonator, crisp snap\u003c\/li\u003e     \u003cli\u003eHi-Hat: 6 dissonant square-wave oscillators, mixed, filtered and overdriven\u003c\/li\u003e     \u003cli\u003eFM Drum: 2 interacting oscillators — kick, tom, bell, cymbal, ring mod modes\u003c\/li\u003e     \u003cli\u003e4-channel drum sequencer: tap-in pattern entry, auto-looping, shift register architecture\u003c\/li\u003e     \u003cli\u003eOutput Mixer 2: 4 channels, per-channel FX sends, master insert, built-in drive\u003c\/li\u003e     \u003cli\u003eBBD delay: analog bucket-brigade, flanger and delay modes\u003c\/li\u003e     \u003cli\u003eDiode compressor: sidechain input\u003c\/li\u003e     \u003cli\u003eEvery module breadboard-explorable before assembly — full educational path included\u003c\/li\u003e     \u003cli\u003e8 detailed downloadable build guides\u003c\/li\u003e     \u003cli\u003eDifficulty: intermediate; estimated build time: 6–8 weekends\u003c\/li\u003e     \u003cli\u003eFormat: Eurorack — all modules compatible with larger systems\u003c\/li\u003e     \u003cli\u003eDesigned by Erica Synths × Moritz Klein (mki × es.EDU series)\u003c\/li\u003e     \u003cli\u003eAvailable as module set only, or as System with enclosure, PSU and patch cables\u003c\/li\u003e   \u003c\/ul\u003e   \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e   \u003cul\u003e     \u003cli\u003eFormat: Eurorack (±12V standard)\u003c\/li\u003e     \u003cli\u003eNumber of modules: 8\u003c\/li\u003e     \u003cli\u003eDrum voices: 4 (Kick, Snare, Hi-Hat, FM Drum)\u003c\/li\u003e     \u003cli\u003eSequencer: 4-channel, tap-in, shift register architecture, auto-looping\u003c\/li\u003e     \u003cli\u003eEffects: BBD delay\/flanger, diode compressor with sidechain\u003c\/li\u003e     \u003cli\u003eMixer: 4 channels, per-channel FX sends, master insert, drive\u003c\/li\u003e     \u003cli\u003eSystem version includes: Eurorack enclosure with integrated 1A power supply (±12V), power distribution bus board, 15 braided patch cables (5× 20cm, 5× 30cm, 5× 60cm)\u003c\/li\u003e     \u003cli\u003eIncluded in both versions: EDU DIY Kick Drum, Snare Drum, Hi-Hat, FM Drum, Drum Sequencer, Output Mixer 2, BBD, Compressor kits + 8 downloadable build guides\u003c\/li\u003e     \u003cli\u003eRecommended breadboard tool: LABOR (Erica Synths)\u003c\/li\u003e     \u003cli\u003eWarranty: 2 years (manufacturing defects)\u003c\/li\u003e   \u003c\/ul\u003e \u003c\/div\u003e","brand":"Erica Synths","offers":[{"title":"Default Title","offer_id":53395117769041,"sku":"59203","price":612.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/EricaSynthsKONSTRUKT-8EDUDIYDrumSystem1.jpg?v=1774968077","url":"https:\/\/wrdtunes.com\/de-fr\/products\/erica-synths-konstrukt-8-edu-diy-drum-system","provider":"Wired Tunes","version":"1.0","type":"link"}
