Phase 3 (L39, ST13, ST9, ST10).
- L39: deleted codegen/seed-midi-devices.ts. It regenerated — and therefore
silently CLOBBERED — the hand-tuned device schemas it had originally created.
Its purpose is served and git retains it. Confirmed nothing invokes it (the
root package.json that once might have was deleted in Phase 1).
- ST13: moved the provenance artifact out of the repo root. AUDIT CORRECTION:
the finding's proposed destination, schemas/midi_devices/synth-midi-cc.sources.json,
would have BROKEN codegen and CI — generate-midi-devices.ts treats every *.json
directly under that directory as a device template and ajv-validates it, and
the sources file has no device_id/midi/params, so the generator would exit
non-zero. It went to schemas/midi_devices/sources/ instead.
- ST9: schemas/schema.json's own description stated the direction of truth
BACKWARDS. Rewritten: schemas are canonical, codegen emits C++ and TypeScript.
(The audit cited params_notes.md; the real path is schemas/modes/params_notes.md.)
- ST10: codegen/README.md rewritten against current reality — it described
retired playground paths and a phantom temp dir.
Descriptions are never emitted, so this is behaviour-inert; proven by
regenerating all four generated directories byte-identically.
New SLP-Workshop firmware variant (Synth Library Portland), built on the
MEMLCelium engine + MLP shape. Ports the two post-fork learning-algorithm
changes from upstream memllib InterfaceRL into the shared nisps/ml core,
runtime-configurable (no compile-time switch), inert by default:
- nisps/ml/jolt.hpp: Jolt — held continuous weight morph over the flat
weight buffer + post-release LR ramp (kJolt* constants verbatim).
- nisps/ml/ou_noise.hpp: OUNoise<N> — Ornstein-Uhlenbeck exploration walk
on the output vector (theta=0.02, dt=0.001, kMaxAmplitude=0.65).
Both wired into ModeBase so every mode gains jolt_press/jolt_release/
jolt_lr_scale + set_explore_intensity; gated so existing modes stay
bit-identical (parity + golden tests green). Firmware surfaces them on
TogB1 (Jolt) and RVX1 (explore). New SLPWorkshopMode mode + schema +
codegen; firmware alias + .ino variant; playground mode registration.
Tests: jolt + OU unit tests, ModeBase learning integration incl. an
inert-parity test proving SLP-Workshop == MEMLCelium with features off.
Verified: cpp tests, wasm build, native↔wasm parity, lint, codegen
golden, playground typecheck. Firmware compile/e2e/hardware are
environment-bound (no arduino-cli/submodules/browser here).

Add a durable, committed source of truth for external MIDI synth control:
- synth-midi-cc.json: verified CC maps + provenance/sources (8 devices researched)
- schemas/midi_device.schema.json + schemas/midi_devices/*.json: 6 CC-controllable
device templates (Moog Sub 37/Sub Phatty, Creamware Pro-12 ASB, Elektron Analog
Keys, ASM Hydrasynth, Roland JD-800), params keyed {id, cc, label, min, max,
default, group}.
- codegen/generate-midi-devices.ts (isolated from the mode golden test) emits both
nisps/midi/generated/midi_devices.hpp (no-heap constexpr, firmware+WASM) and
manifold/src/midi-devices/generated/ (typed catalogue for the browser).
- codegen/seed-midi-devices.ts: reproducible seed from the research artifact.
Lets a performer pick a device and address its parameters by name (not CC number)
on both the firmware and the Manifold browser engine.
