- nisps/pipeline/input_chain.hpp: faithful f32 port of the manifold input pipeline (invert→deadzone→circular clamp→momentum-modulated zoom→centred power→EMA→momentum update). Caller-supplied dt, internal accumulated clock (no wall clock — deterministic; matches the P1 fixtures' clock contract). Fixed-capacity velocity ring; serialisable state. - nisps/pipeline/output_chain.hpp: curve→EMA→slew→freeze(+per-output mask) chain, capacity-templated (browser cap 4096; firmware would use NOut). - nisps/core/math.hpp: + centered_power(x, exponent) (both chains use it). - bindings: nisps_pipeline_create/destroy, nisps_input_set_config(15-float wire layout)/process/reset, nisps_output_set_config/set_freeze_mask/ process/reset, pipeline state save/load, nisps_curve_apply(+batch) (ids 0-6 = Curve enum, 7 = centred power). - parity v5 Stage 7: rational (transcendental-free) traces through both chains (2 configs each) + full curve catalog — 1273 floats PASS, the pipeline floats bit-identical native↔WASM. - ctest test_pipeline.cpp: deadzone remap, circular clamp, zoom+freeze, sticky anchor, frame-rate-independent EMA, momentum zoom-out/recovery, state round-trip, slew, freeze gate/mask, reseed-on-length-change, centred-power endpoints. Part of one-core-engine-refactor P4; the manifold TS switch follows. |

Neural Interactive Shaping of Parameter Spaces

Firmware
The hardware firmware targets the MEMLNaut RP2350 build and uses repo-local helper scripts for the known-good build configuration:
git submodule update --init --recursive
scripts/build-firmware.sh
scripts/flash-firmware.sh
scripts/build-and-flash-firmware.sh
Notes:
- The scripts build for
rp2040:rp2040:solderparty_rp2350_stamp_xlwithOptimize3. - The build forces C++20 because the firmware uses
std::spanand concepts. build-firmware.shaccepts an optional variant name such asMEMLCeliumorBreakOr. Matching remains case-insensitive, somemlceliumstill works. If you omit it in an interactive shell, the script parsesMEMLNaut-NISPS.ino, prompts for a variant, and rewrites the activeMEMLNAUT_MODE_TYPEbefore building.flash-firmware.shaccepts an optional mountpoint argument, or auto-detects common UF2 bootloader mounts such as/run/media/$USER/RP2350and/run/media/$USER/RPI-RP2.
Manifold (browser app)
Try NISPS in your browser — no hardware required. Manifold is the React front-end running the same C++ engines + ML as the firmware, compiled to WASM:
cd manifold
bun install
bun run dev
Staging deployment: https://meml.lnfinitemonkeys.org/next/
Train a neural network to map input gestures to synth parameters through interactive machine learning: place examples, or use verdict-based feedback (explore-and-place, geometric dislike).
