Me Here 964dee01d6 pm-synth: port engine.js 808/909/GM voices to Rust + host wav renderer 
pm-synth: a polyphonic drum-voice synth, a faithful f32 port of engine.js DRUMS
(tone/ampEnv/v_noise/metalHat/clap recipes; RBJ biquads; exp envelopes). A Synth
mixes active Voices sample-by-sample (transport-agnostic: offline render now,
real-time device buffer fills later). All 808/909 + GM voices ported.

synthrender (host bin): parse a groove -> track-format schedule -> trigger voices
at click times -> 16-bit/48k mono WAV. Applies the editor default kit (kick->
kick909 etc.). Renders four demo grooves to audition off-bench.

This is the reusable half of the audio feature; the device port (no_std +
fixed-point/table osc, since the M0+ has no FPU) comes with the transport.

README.md

Rust port — track-format crate (Stage 1)

Pure parse/serialize codec for the track DSL, validated against the shared golden vectors (tests/fixtures/track-format.json) — the third implementation alongside engine.js and app.py. See docs/rust-port.md for the staged plan.

All tooling runs in a container (per the develop-in-container rule):

./rust/run.sh            # cargo test — runs the conformance + idempotency suite
./rust/run.sh cargo build
./rust/run.sh bash       # interactive shell in the crate
