A wavetable synth with a real-time physical cymatics engine. Your sound draws living Chladni figures — 400,000 particles, real physics, rendered in 4K.
Most synths give you sound. Sonicrama gives you the sound and the shape it makes — the two are the same object, computed together, in real time.
Four oscillators. Per-key meta-tuning across all 128 keys, with .scl/.tun import and export, a free root, and a different tuning table per oscillator. Unison ×7, follow modes (ratio · math · beat-frequency), a modulation matrix, four Bézier envelopes, and a multi-mode filter.
A GPU engine solves the modal equation of a real vibrating plate — Bessel mode shapes, Faraday-wave dispersion for liquids — and drives 400,000 particles with your audio, live. For the sand plate the frequencies and spatial scale are physically exact. Not a visualizer inspired by cymatics: the physics itself.
The pattern isn't a property of the number — it's a property of the system: the plate, the vessel, the way it's driven. Change one thing, and the figure changes with it.
Feed the plate a frequency and the grains arrange themselves into its modal figure — the same experiment Ernst Chladni first drew with a bow in 1787, now solved 60 times a second on a GPU. Every figure is the exact answer to a specific tone on a specific plate.
Switch the vessel to liquid and the surface answers with Faraday-wave dispersion — the caustics you'd see in a real driven fluid. Adjust density, viscosity, depth: the mathematics follows the material, not a preset animation.
The Lissajous view traces the raw geometry of the signal itself: two oscillators, one luminous figure. Two temperaments on the same chord draw two different curves — you can see the tuning.
The whole instrument — a laboratory you play. (Press play.)
Leave your email and I'll write to you the moment it opens.
€99, one-time — yours forever. No subscription.
Runs in Logic, Ableton, Bitwig, Reaper and more. Windows is planned — I'd rather say "when it's ready" than promise a date.
I make Sonicrama on my own. Every choice on this page, and every answer to your email, comes from me. And if you want to talk about the ideas behind the instrument — the research, the music, the old questions about sound — I read everything.

Soon — it's in the final stretch. Leave your email and you'll hear it from me first, the day it opens. No countdown games, just one message.
Yes — a free demo you can keep. The moment it's out I'll send you the link, so you can try the whole thing before you decide.
Three things: sessions run 15 minutes (reopen to continue), exported clips carry a small engraved signature, and presets can't be saved. Every sound-design feature — all four oscillators, the full tuning system, the physics engine — is unlocked. The demo never expires.
AU, VST3, CLAP and standalone, from day one — so it runs in Logic, Ableton, Bitwig, Reaper and anything that hosts those formats. macOS only for now (universal binary for Apple Silicon and Intel, macOS 11 and up); Windows is planned.
One perpetual license, activated on up to 3 machines, used one at a time. It works fully offline — no server check, ever — and it's resellable. Activation happens once per machine through your browser; you never type a password into the plugin. Licensing is handled by Zaplab, which develops and manages licenses for AcusMagic products.
Real. The engine solves the modal equation of a vibrating plate (Bessel mode shapes) and Faraday-wave dispersion for liquids, driven by the actual audio. For the sand plate the modal frequencies and spatial scale are physically exact — cross-checked against published Chladni-plate measurements.
There's an introductory launch price for the first few weeks; afterwards it rises to the standard price shown above. Buying now includes a 14-day, no-questions-asked refund, so there's no risk in deciding early.
