Phase 3 (L8). Pure statement-for-statement relocation into dsp/ratio_seq.hpp, dsp/seq_clock.hpp and core/event_queue.hpp. AUDIT CORRECTION: L8 says "breakor and elysiamorf duplicate ratio_seq". That is false — ElysiamorfEngine has no ratio_seq at all; it triggers continuously via FM operators. The real duplicate pair is BreakOrEngine and MEMLCeliumEngine, whose copies are byte-for-byte identical. Elysiamorf did share the clock and event-queue machinery, so it uses those. memlcelium now includes the shared ratio_seq too, which is what actually closes this finding. Deliberately NOT folded into core/ring_buffer.hpp: RingBuffer is an atomics-based cross-core SPSC channel (its header says so), whereas the engines' event queue is produced and drained on one thread. Reusing it would have meant paying for atomics to serve a single-threaded FIFO. The distinction is now recorded in MAP.md so the next audit does not read them as duplicates. Bit-exactness: verified the MIDI-clock tick and bar-phasor tick preserve the original operation order with no floating-point re-association, and that EventQueue keeps the original `% N` indexing rather than adopting RingBuffer's bitmask. The golden suite (nisps_golden_tests) and the native<->WASM parity blob both pass unchanged — they are the check, and they were not re-baselined. |

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).
