Ring Arc

from @pluginui

A chord as a thick band over a ring of notes (a key's seven in line-of-thirds order, so stacked thirds are neighbours), with the chord before it as a ghost band on an outer track and the next on an inner one. Notes read in one colour language: shared notes solid and tied radially to the ghost track, arriving notes in the accent, leaving notes dashed, and the shared count in the centre. Editable: drag the band to move the chord, drag an end knob to widen or narrow it (triad, seventh, ninth), tap a note to toggle it, with keyboard equivalents. An optional outer ring of real note names with semitone ticks turns to transpose.

All @pluginui

Audio Clip Player component
@pluginui
Host-controlled play/pause, seekable waveform and time display.
Audio Clip Wave Layer component
@pluginui
Audio Clip Wave Layer shared by module faces and application hosts.
Beat Grid Scope component
@pluginui
A dynamics scope's chrome: a bars-across grid with bar lines heavier than beats and an optional sixteenth grid, a dB gutter reading downward from 0, a dashed hard-ceiling line with its own label (dashed because a budget is a limit, not a measurement), a playhead, and beneath the plot a strip of event lanes drawn as onset ticks at their exact beat — so a swung event visibly sits off its gridline — sharing the plot's own xForBeat, with the playhead continuing through them. It draws no signal itself: `children` is a render function handed the resolved layout, so a prediction envelope, a measured overlay and a waveform all live in the SAME coordinate space as the grid and cannot disagree about where a beat is. The playhead is either given as a phase (null draws none, which is the right picture for a stopped transport) or derived from a host transport through useBeatClock, whose source is reported back so the caption can distinguish host-locked from free-running. SVG, no measurement, renders on the server.
Button component
@pluginui
Canonical shadcn and Base UI button used by portable controls and website aliases.
CC Binding Editor component
@pluginui
Portable control-level MIDI CC menu and binding editor: assign a controller number and channel by right-clicking a control, then edit range, response curve, learn, or remove. The existing badge and drag-drop source strip remain optional paths through the same `midi` callbacks.
CC Control Chrome component
@pluginui
One reusable frame for custom controls: parameter-path resolution, drag target, activity state, editable badge, and the shared MIDI context menu.
CC Knob Strip component
@pluginui
A row of MIDI CC chips you can turn and reorder. Turning is the ordinary knob gesture; reordering starts from a separate grip handle and works with pointer or arrow keys.
CC Mapping List component
@pluginui
Every MIDI CC mapping of a host as one grouped list: by module or rack instance, with a by-CC sort, search and filters. Rows show the CC, input and channel, target, range and live activity, with Learn, Pick control, enable and remove; opening a row gives CC, channel and range, and Advanced adds input, value mode, takeover, curve and invert. Import, export, reset and clear are callbacks; the list keeps only view state.
CC Source Strip component
@pluginui
The MIDI CC chips you drag onto a control to bind it: the mod wheel first, then the expressive controllers, then a numeric picker for the other hundred-odd numbers. Each chip is draggable by pointer, assignable from the keyboard, and pulses when its controller sends traffic.
CC Unmapped Notice component
@pluginui
The host's one toast for a hardware controller that moved but is not mapped: the source and channel, a live value, a chip you drag straight onto a control, Pick control (click or arrow keys and Enter) and Ignore. It never takes focus, fades after the control goes quiet, and guides any source-first pick. Every edit goes through the shared CC drag controller, so drops into sandboxed face frames work too.
Chladni Plate component
@pluginui
Nodal patterns for a set of frequencies — the figure sand draws on a driven metal plate. Either a particle simulation finding the nodes over time or the standing wave as a field, on a square or circular plate. Parameter-driven, so it needs no audio source.
Chord Graph component
@pluginui
How the chords in a progression connect, as a shared-pitch-class network: an edge between every pair sharing a note, weighted by how many. A chart tells you the order chords arrive in; this tells you why one slides into the next and another lands like a cut — so you can see which substitutions are available before trying them.
