Erica Synths EDU DIY FM Drum

Introducing an FM Drum circuit that fuses analog punch with metallic tones of FM synthesis. This DIY kit offers a wide range of sounds for your patches, from kicks to toms, metallic clangs and more – a great addition of versatile, rhythmic elements to your system.

Erica Synths and Moritz Klein have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesiser circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, you're taken through the circuit design process step by step, explaining every choice made and how it impacts the finished module.

Key Features:

• Versatile analog drum circuit that combines punchy low-end with metallic FM synthesis tones.
• Capable of generating a wide sonic range including kicks, toms, bells, and metallic clangs.
• Dual oscillators with switchable sine and pulse waveforms for diverse harmonic textures.
• Frequency Modulation (FM) on/off switch with a dedicated tune depth control.
• Built-in adjustable decay envelope that can be routed directly to the pitch for percussive sweeps.
• Comprehensive CV connectivity with inputs for Trigger, Accent, Tune CV, and Decay CV.
• Educational DIY design developed in collaboration with Moritz Klein to teach analog circuit fundamentals.
• Step-by-step build guide included that explains every component's impact on the final sound.
• Convenient faceplate reference chart showing switch combinations for specific drum sounds.
• Compact 16HP Eurorack module format with a 35mm mounting depth.
• Through-hole component (THT) kit designed to be beginner-friendly for those learning to solder.
