NewTapechild UDS-16
Soviet Drum Synthesizer
Kicks, snares, hats, toms and metallic percussion, synthesized in real time. Four models: two from the Lel UDS channel, one from the Formanta Rockton, one of our own.
Tapechild UDS-16
Soviet Drum SynthesizerFour drum-synth models built from two rare Soviet circuits — and one that is ours alone. No samples: every hit is synthesized as you play it.

Our instruments
Tapechild ships one plugin at a time, and only when the hardware behind it is understood well enough to extend rather than imitate.

Before anything else
Full pieces in different tempos and moods. Every drum in them is generated by the engines, not replayed from a library.
From someone who shipped a record with it
“The controls are so comfortable and well laid out that everything fell into place within minutes. The instrument slotted perfectly into my aesthetic and became a powerful addition to my drum sections.”Read the full review and hear his track →

Too strange for its era. Exactly right for yours.
AI can generate endless tracks. It cannot replace the choices, accidents and obsessions that make music feel alive. Tapechild builds instruments for musicians who still want their fingerprints on every sound.
We study rare hardware, preserve its unstable clocks and nonlinear behaviour, then turn those ideas into original tools — bringing surprise, tension and soul back into modern production.

We look for instruments history skipped: obscure drum synths, odd tape systems and circuits most producers will never get to touch.
Documented synthesis principles inform an original real-time engine. A note is generated again every time you play it — never replayed from a sample.
The historical ideas become an original modern instrument. Tapechild finishers are added where they help the sound land in a record made today.
We go after instruments that were built once, in small numbers, and then left behind — read the schematics, measure what the parts actually do, and rebuild the behaviour as an engine rather than a recording.
What survives the trip is the awkward part: free-running clocks, drifting components, stages that misbehave under load. That is the part a sample cannot hold, and the reason these instruments still sound like nothing else.



A trigger pulse, a ringing circuit and an envelope. How analog drum machines build a kick instead of playing one back, which famous machines really qualify, and what the sound costs today.

The reverb-into-a-gate chain behind the decade’s biggest snare, with the settings that matter and recipes for Ableton, Logic and FL Studio.

Formanta, Lel, Marsh and Elsita, and why most instruments filed under “Soviet drum machine” are better understood as playable, trigger-driven percussion synthesizers.
