This is the real thing: the same trained engine and the same deviation kernel that ship in Bacara Plugin - which adds 64 steps, 12 variants, ten deviation lanes, scales, macros, MIDI export, and your DAW.
How does this work?
This page runs the product's actual C++ engine, compiled to WebAssembly. The generator, the deviation kernel and the scale quantizer are the exact code that ships in the full product, and every build is tested to produce byte-for-byte the same patterns as the native version. The melodies come from a character-level language model that reads its trained model file, about half a megabyte, right in your browser. The compiled engine itself weighs 25 KB. The 303 voices are hand-built Web Audio, no samples. And there is no server doing any of this: the pattern you hear is computed on your machine and lives entirely in the URL, which is why a shared link reproduces it exactly, deviations and all.
