- Modular hardware-style panel: System / Oscillator / Filter / Envelope
/ LFO / Drive / Echo / Output / Keyboard sections with labeled frames
- HOLD switch: pads become latching toggles (switching pads retunes the
held note, unlatching or disabling HOLD releases it)
- Fuller Web Audio voice: waveshaper drive, full ADSR, feedback delay
(time/feedback/mix), LFO target switch (cutoff or pitch via detune),
octave/detune/glide with live retuning of held notes
- More of the library in service: MetalKnob (drive, with value bubble),
VintageKnob (echo time), horizontal LEDFader (echo mix), XYPad
two-way-linked with the cutoff/res knobs (exponential x-axis mapping),
SegmentDisplay live frequency readout, 4 preset buttons that glide
every knob via animateChanges
- Disambiguated synth aria-labels from gallery demos; octave readout
fixed via decimals/format
- SteppedKnob now honors the format prop for numeric readouts
Docs/playground accuracy (from a full docs-vs-source audit):
- Playground: drag-feel select covers pickup/relative rotary modes, is
disabled for faders, and generated code no longer emits props the
target component does not accept
- API/README claims corrected: Shift-fine wheel scope, wheelStep and
decimals defaults, trackInset row, data-part and ref-forwarding
scope, VintageKnob readout exception, Meter peakHold tag, stale
component lists, aria-valuetext wording, also-exported list
API consistency fixes surfaced by the audit and the tutorial:
- Keyboard gestures now fire onChangeStart (bracket parity with drag/
wheel - fixes gesture-scoped undo patterns)
- name (hidden form input) added to Fader, LEDFader, ImageKnob
- PushButton gets a themed keyboard-only focus ring + data-focus-visible
New docs content:
- Getting Started: 7-step guide with live examples and a gotchas list
- Advanced guide: 8-step channel-strip tutorial ending in a live,
themed, gesture-undoable strip with meter (plus headless demo)
- Synth section: playable Web Audio synth - osc/filter/env/LFO/master
all dreamknob controls, momentary-pad keyboard, analyser-driven Meter
- valueBubble/bubbleFormat: floating readout above knobs while dragging
(Knob-based skins + ImageKnob)
- animateChanges: rAF ease-out tween of the pointer on programmatic
value changes; user gestures snap; prefers-reduced-motion disables
- wrap: endless encoder mode — values and relative drags roll around
min↔max; pairs with angleOffset={0} angleRange={360}
- XYPad: two-parameter pad with absolute drag, arrow keys (Shift
coarse), Escape cancel, double-click reset, grid/crosshair, focus
ring, hidden form inputs, change meta
- AlphaDisplay: fourteen-segment alphanumeric LED (A-Z, 0-9, symbols,
decimal points, chars padding/align, glow/skew)
- PushButton: studio panel button with LED strip — toggle or momentary,
controlled/uncontrolled, aria-pressed, hidden form input
- Docs: five new gallery cards incl. animated preset demo, API rows,
README
- rotaryMode: 'absolute' | 'relative' (angle deltas, no grab jump) |
'pickup' (MIDI-style: engages when the pointer sweeps past the value)
- dragAcceleration: velocity gain for relative drags (Shift bypasses);
hideCursorOnDrag hides the cursor mid-gesture
- Wheel: trackpad delta accumulation (flicks can't rocket the value,
one notch per wheel click), wheelStep override, wheelRequiresFocus
opt-out of the hover scroll-trap
- onChange/onChangeStart/onChangeEnd now receive { source: 'drag' |
'wheel' | 'keyboard' | 'reset' | 'api' }
- Every component forwards a ref to its root; name prop renders a
hidden form input; SVG primitives carry data-part attributes
- Arc gradient: position-anchored color stops rendered as sliced arcs
(mixColors/sampleGradient exported, unit-tested)
- New read-only Meter: LED level meter with peak hold, zones, readout
- Fader capColor/capLength for custom handle styling
- Docs: Meter/gradient/drag-feel gallery cards, white-cap fader demo,
API rows, README
- Keyboard focus-visible ring on all controls (WCAG 2.4.7), suppressed
for pointer grabs; focusRing prop to customize or disable
- aria-orientation on track modes; data-dragging/-disabled/-readonly/
-focus-visible state attributes; disabled dims, readOnly drops the
grab cursor
- Escape cancels a drag and restores the pre-gesture value
- Controlled mode no longer desyncs when the parent rejects onChange
- Second concurrent pointer can no longer hijack a drag session;
drags cancel when disabled/readOnly flips mid-gesture
- Wheel: onChangeStart symmetry, settle flush on unsubscribe, dominant-
axis direction (fixes macOS Shift+scroll reversal), ignored mid-drag
- Shift+wheel and fine multipliers now work on stepped/values knobs
- Fader/LEDFader track mapping inset-aligned with handle travel (no
value jump when grabbing the cap); LEDFader zones sorted
- roundTo no longer returns NaN for exponential-notation values;
logTaper falls back to linear for invalid ranges; decimalsFromStep
shaves float noise; findClosest([]) returns the input
- Double-click reset brackets with onChangeStart/End
- MetalKnob honors showValue/unit/format; VintageKnob omits them from
its type; TickLabels extracted as a public primitive
- SegmentDisplay: letters/hex charset, dash overflow instead of 888
React + TypeScript knob/fader library with a headless interaction core
(rotary, relative-drag and track modes, wheel, keyboard, a11y), SVG
primitives, nine prebuilt skins, seven-segment display engine, and a
Vite showcase with gallery, live playground and API docs.
