synthdef -- a native Rust port

synthdef is a native Rust port of nanosynth.

It reimplements the SynthDef compiler in Rust, driven by this package's language-neutral UGen spec (spec/nanosynth-ugens.json) and validated byte-for-byte against nanosynth's compiler via shared golden fixtures, so the two implementations cannot silently diverge.

On top of the compiler it builds a full stack:

  • A nanosynth-style Server -- load SynthDefs, play synths and groups, set controls by name, buses, buffers, node notifications, and offline / real-time rendering.

  • SuperCollider-style pattern sequencing (Pbind/Pseq/Pwhite/Pwrand/...) with per-event timing, polyphony, gate-release, and a background clock.

Both run over the pure-Rust plyphon synthesis engine (which has no process-global state and also compiles to wasm32).

The goal is a portable core that runs where a Python runtime cannot -- other languages via a C ABI, the browser via WASM, or a DAW plugin. The nanosynth compile CLI and the SCgf format spec document the same binary format both projects emit.
