Add a "grab → move → drop" gesture that moves an existing positive
example's output to a new input position, preserving the output. This is
the new core's home for upstream InterfaceRL's drag-store/reposition-commit,
distinct from Explore→Place (which places newly-auditioned scratchpad sounds).
- nisps/ml/feedback.hpp: begin_reposition()/commit_reposition()/repositioning().
Reuses the Placing state (static_output holds the carried vector) but a
reposition_ flag makes commit AND the mode-switch teardown SKIP the weight
restore — the real net is never set aside here, so restoring snapshot_ would
clobber the live trained net. Guards cancel_place + abort_explore_place.
- firmware glue: state-gate Toggle B. Exploring → reroll/nudge (unchanged);
Idle → MomB1 grab, MomB2 drop (commit + add_example + train). The 4D variant
has no joystick button, so the gesture lives on the momentary toggle. Also
fix a stale top-of-file control-map comment that contradicted the bindings.
- tests: 4 reposition cases (hold without snapshot; commit stores carried
output with no restore; mode-switch aborts without clobber; begin-only-Idle).
- MAP.md: document the full ExploreAndPlace lifecycle + reposition wiring.
Audio-hold (carrying the sound audibly during the move) remains the existing
unwired static_output() TODO and affects Explore→Place identically.
Firmware compile unverified (no arduino-cli); host tests + lint pass.
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 glue/settings_view.hpp: wire_settings(mode) registers a "Joystick"
SingleSelectView on the MEMLNaut display carousel (TFT + rotary encoder, same
DisplayDriver as SystemView/SelfTest). For the 4-input two-joystick modes,
"Single" pins ML input channels 2,3 (the second joystick) to neutral via
ModeBase::set_input_pinned — the network is never rebuilt and trained state
survives toggling. Default is Dual. Only registered when input arity == 4.
Called from MEMLNaut-NISPS.ino setup() after addSystemInfoView(). MAP.md +
CLAUDE.md glue listings updated.
NOTE: compile-unverified — no arduino-cli/RP2350 toolchain on this host and no
hardware; needs scripts/build-firmware.sh + a flash test (chokepoint A).
Joystick -> MLP -> MIDI CC for an external hardware synth, using the
compile-time device templates from nisps/midi/generated. ExternalSynthMIDIMode
<const MidiDevice&, NOut> mirrors SoundAnalysisMIDIMode (NoOpEngine,
kRouteOutputsToEngine=false, pushes ControlChange events). A consteval
pick_cc_slots curates which NOut params fill the output slots (prefers musical
params over Bank Select/global). Adds six flashable variants
(MEMLNautModeExtSynth{Sub37,SubPhatty,Pro12,AnalogKeys,Hydrasynth,JD800}) wired
into mode_select.hpp + the .ino variant list + NISPS_ST guards, and a src/nisps/
midi symlink so the sketch tree can reach nisps/midi.
Host-compile-verified under C++20 (incl. via the sketch include path) and
lint-clean; full arduino-cli build + flash is on the hardware (no toolchain here.
Map enter/exit-explore, reroll, nudge, begin-place, commit-place to the
peripheral buttons via the shared FeedbackController. (Not compiled here —
no arduino-cli; Placing-audition static_output hook is a flagged follow-up.)
Move the Arduino sketch into firmware/MEMLNaut-NISPS/ and bridge the
hardware (memllib) to the platform-agnostic nisps/ library through a
slim glue layer. Delete the legacy root-level *AudioApp.hpp,
modes/MEMLNautMode*.hpp, voicespaces/, IMLInterface.hpp, XiasriAnalysis,
and the src/memlp submodule.
Glue layout (firmware/MEMLNaut-NISPS/glue/):
audio_driver.hpp - bridge memllib block callback to Mode::process
via per-Mode templated trampoline (no virtual dispatch)
peripherals.hpp - joystick/pots/buttons -> Mode::set_input + ML primitives
midi_io.hpp - MIDI in -> mode.note_on/update_bpm/set_playing,
drains mode ControlEvent ring -> MIDI UART
mode_select.hpp - using-aliases mapping MEMLNautMode<Name> to
nisps::modes::*Mode (build script rewrites the
#define MEMLNAUT_MODE_TYPE line)
input_router.hpp / output_router.hpp - top-level wire/drain entry points
The sketch tree uses src/{memllib,daisysp,nisps} symlinks because
Arduino-CLI rejects ".." in include paths from sketch-tree headers.
mode_select.hpp #undefs Arduino's sq/min/max/abs/round macros before
including nisps headers (some nisps engines use those identifiers as
method names). The audio bridge struct is extern in the header and
defined in the .ino because inline + __not_in_flash section attribute
collide at link time.
Verification: arduino-cli compile succeeds for PAFSynth, ChannelStrip,
and BreakOr (rp2040:rp2040:solderparty_rp2350_stamp_xl:opt=Optimize3,
-std=gnu++20). Host C++ tests under nisps/build still pass (3 binaries,
110+ tests). Build script (scripts/build-firmware.sh) updated to point
at the new sketch path; mode-rewrite logic unchanged.
Closes meml-gkm.
