Adds EngineSwitcher module with clickable engine cards (active highlight,
coming-soon greyed state, loading bar animation, confirm-on-switch when
training data exists). Wired into the Engine drawer; C15 active,
Additive/FM marked coming-soon with toast. Dock title reflects active
engine; engineId persisted to/restored from localStorage.
- OSC pill: add status dot indicator (gray=off, green=connected,
pulsing yellow=connecting), use flexbox for reliable alignment
- OSC pill: add hover state for better affordance
- Synth panel: add separator line above OSC row so it doesn't
blend into the arpeggiator controls
- Bottom sheet: increase expanded height from 55vh to 60vh so
OSC row isn't cut off on mobile
- Help modal: update step 3 to mention the OSC pill in the
bottom bar as the primary connection method
Browser-side OSCOutput module sends parameter values over WebSocket to
a companion Deno bridge script that converts them to OSC/UDP messages.
Enables controlling SuperCollider, Max/MSP, Pure Data, TouchDesigner,
or any OSC-capable software from the NISPS playground.
- Browser module (js/synth/osc-output.js): WebSocket client with
auto-reconnect, throttle (~20fps), and dead-zone filtering
- Deno bridge (osc-bridge/bridge.ts): zero-dependency, compiles to
standalone binaries via deno compile for Linux/macOS/Windows
- Test receiver (osc-bridge/test-receive.ts): terminal dashboard
showing live OSC parameter values with bar charts
- OSC pill button in floating bar for quick connect/disconnect
- Help modal section with platform-aware download, setup guide,
and examples for SuperCollider/PD/Max
- GitHub Actions workflow for cross-platform binary builds
- OSC sends in both visual and synth modes
Re-apply fixes from ddb6b77 that were lost in the arpeggiator restore:
- play-btn: align-self: flex-start (pin to top)
- Play drawer: trigger on .play-btn:hover instead of parent :hover
(prevents preset select from opening the drawer)
- preset-select: align-self: flex-start (pin to top)
Restore the original arpeggiator as the default sequencer. ShapeSeq
code is preserved but gated behind a URL feature flag (?shapeseq=1):
- Arpeggiator import, state, and all wiring fully restored
- ShapeSeq modules loaded via dynamic import() only when flag is on
- ensureShapeSeqInit() creates engine/viz/UI lazily on first audio start
- animate loop routes inputs to ShapeSeq only when flag + playing
- setOutputMode shows/hides ShapeSeq container only when flag is on
- HTML: ShapeSeq container added but hidden by default
- CSS: ShapeSeq styles added (inert when container is hidden)
All 13 ShapeSeq modules in playground/js/shapeseq/ are untouched.
To test ShapeSeq: add ?shapeseq=1 to the URL.
- Remove Arpeggiator import and all arp references from a-app.js
- Add ShapeSeq imports (ShapeSeqEngine, StepVisualizer, ChainBuilderUI,
getDefaultBus) and lazy initialization on first audio start
- In synth mode: show ShapeSeq container (circular viz + chain builder),
hide flow-field particles. Visual mode unchanged.
- Route joystick or hand tracking inputs to shapeSeq.setSequenceInputs()
each frame; render step viz at 60fps
- Add HTML: #shapeseq-container with #shapeseq-viz canvas and
#shapeseq-chain wrapper, sequencer transport controls (play/stop,
tempo, step count)
- Add CSS: full-screen flex layout, viz takes upper 45%, chain builder
scrollable below, hidden by default
- Quick play button wires to ShapeSeq start/stop instead of arp
Closes meml-6ry. This completes ShapeSeq Phase 1.
- Change drawer hover trigger from .synth-quick-controls:hover to
.play-btn:hover ~ so hovering preset selector no longer opens it
- Add .play-drawer:hover to keep drawer open when mouse moves to it
- Set align-self: flex-start on play-btn and preset-select to prevent
vertical layout shift when drawer appears
Hand tracking via webcam as alternative to joystick input:
- Right hand tracks 14 derived features (palm XY, finger curls, spread,
roll, pitch, pinch) through a separate 14-input MLP
- Left hand gesture recognition (1 finger = thumbs up, 2 = thumbs down)
with 400ms debounce hold
- Split-zone PIP display (no camera feed, skeleton only) with dashed
divider and cross-zone dimming
- Dual IML architecture: independent imlJoy (2 inputs) and imlHand
(14 inputs) with pointer swap, preserving training data per mode
- Dev panel (?devmode=true): draggable/collapsible floating panel with
sliders for MediaPipe confidence thresholds, smoothing, gesture hold
time, world landmarks toggle, and live feature bar monitor
- Visual presets always route to joystick IML (prevents dimension mismatch)
- Race condition guard on input mode switching
4 tiers of progressive complexity (Beginner 15 params → Expert 126),
13 presets total with per-param min/max/curve overrides that bias
distributions without clamping extremes. Preset dropdown in UI,
persisted to localStorage, supports ?preset= URL param.
- Glass-style modal explains NISPS, how learning works, and what to expect
- Documents all controls: touch, keyboard, and gamepad bindings
- Shows automatically on first visit (localStorage flag)
- Dismissible via close button, "Got it", overlay click, or Escape
- Reopenable via ? button at bottom right
Relocated the output mode toggle from a floating top-right position into
the bottom floating bar where it's more discoverable. Removed the
duplicate toggle from the expanded sheet. Compact pill-toggle-sm style
fits the toolbar layout.
Merge Examples/RL tabs into single unified toolbar across all four UIs.
Users can now freely mix supervised learning (Add Example + Train) with
RL feedback (thumbs up/down) without switching modes. Param bar dragging
is always enabled.
Add Web MIDI input module (js/synth/midi-input.js) for external MIDI
controllers — routes note on/off to C15 synth, CC 1/2 to joystick.
Add gamepad module (js/ui/gamepad.js) with auto-detection, deadzone,
and axis normalization across all UIs.
Fix synth parameter sync: routeOutputs() now called after trainModel()
in onThumbsUp and loadState to prevent stale params on first joystick
move. Add separate Clear Examples button (dataset only, keeps weights).
- Fix RL buttons stuck high on desktop: media query was overriding
bottom to 196px, now matches mobile 92px
- Add floating Visual/Synth toggle at top-right of immersive view,
synced with the existing sheet toggle
Three redesigns of the playground UI, each exploring a different
interaction philosophy for the NISPS interactive ML engine:
A) Immersive — fullscreen canvas with floating glassmorphism overlays
B) Workbench — dashboard with 2D mapping heatmap as centerpiece
C) Journey — phased UI that dissolves (Explore → Teach → Perform)
All share the same 126-output MLP ([32,48,64] hidden layers), C15
synth bridge, and flow field visualizer. Each adds:
- SynthVisualizer (126 grouped vertical bars) replacing particles in synth mode
- RL as default learning mode with keyboard shortcuts (1/2)
- Follow mode for trackpad exploration
- ?tame= URL param for safe-range constraining
- localStorage persistence (random on first boot)
- Live iframe previews on designs.html homepage
See devlog/2026-03-21-ui-redesign-explorations.md and meml-2c3 for
remaining refinements identified during browser testing.
