What’s new

Draw the first editor frame on the CPU while the shared GPU context initializes in the background, with paced device recovery and CPU rendering on OpenGL-only Linux.

Show Grain's reported live readers with the chosen envelope and source positions. Requested overlap and the eight-reader limit are displayed separately, with the preview identifying its selected voice.

Keep ordinary playback in small blocks; only connected feedback cycles need sample-by-sample rendering inside their cycle. [History C003](docs/releases/0.5.4-full-history/claims.md#c003).

Use one oscillator-control catalog for the editor, host automation, musical ranges and value formatting, so the same control means the same thing throughout the instrument. [History C005](docs/releases/0.5.4-full-history/claims.md#c005).

Use one placement and connection system for source operators; each source engine supplies its own processing rather than duplicating the whole operator workflow. [History C006](docs/releases/0.5.4-full-history/claims.md#c006).

Make the MUI editor the only product frontend. The old egui and GPUI reference frontends are no longer selectable product editors. [History C007](docs/releases/0.5.4-full-history/claims.md#c007).

Move border and contour rendering fixes into upstream MUI and remove the downstream patch-replay arrangement. [History C010](docs/releases/0.5.4-full-history/claims.md#c010).

Use MUI and its host bridge as upstream Git dependencies rather than shipping a private, uncommitted editor checkout. [History C011](docs/releases/0.5.4-full-history/claims.md#c011).

Separate the shared editor model from frontend rendering, keeping patch editing, persistence and parameter binding independent of the retired UI toolkits. [History C012](docs/releases/0.5.4-full-history/claims.md#c012).

Integrate MUI's native window/input bridge, including the Windows keyboard-capture policy used by the editor. [History C015](docs/releases/0.5.4-full-history/claims.md#c015).

Use editor-parented native Linux file choosers. Cancel pending dialogs when the editor closes and finish owned dialog workers before unload. [History C017](docs/releases/0.5.4-full-history/claims.md#c017).

Rebuild the workspace around a fluid, resizable MUI layout with connected group headers, source cards and operator surfaces. [History C021](docs/releases/0.5.4-full-history/claims.md#c021).

Give oscillator cards a narrow identity rail and contiguous waveform, unison and pan panels, with the waveform as the main editing surface. [History C022](docs/releases/0.5.4-full-history/claims.md#c022).

Make group identity and routing clearer with consistent headers, output readouts, rulers and categorized insertion menus. [History C023](docs/releases/0.5.4-full-history/claims.md#c023).

Redesign operator cards around their actual controls and useful previews instead of unrelated decorative surfaces. [History C024](docs/releases/0.5.4-full-history/claims.md#c024).

Reorder modules through real card/title drags with explicit drag feedback, rather than treating the waveform or source-routing port as a reorder grip. [History C025](docs/releases/0.5.4-full-history/claims.md#c025).

Show concise musical values and units on bound generator controls, and expose matching text to CLAP and VST3 hosts. [History C029](docs/releases/0.5.4-full-history/claims.md#c029).

Identify the build in the masthead, not just the version number, so development and packaged builds can be distinguished. [History C030](docs/releases/0.5.4-full-history/claims.md#c030).

Use a right-side settings drawer with click-away and Escape dismissal instead of the earlier welded reveal. [History C032](docs/releases/0.5.4-full-history/claims.md#c032).

Open the native color picker inline below its swatch and group settings into appearance, audio and account-related controls. [History C033](docs/releases/0.5.4-full-history/claims.md#c033).

Make surface tint, contrast, accent mute, oscillator color, modulation cables, interface scale and resynth detail explicit settings. [History C034](docs/releases/0.5.4-full-history/claims.md#c034).

Use flat accent fills and restrained baselines for envelope and response plots rather than gradient decoration. [History C037](docs/releases/0.5.4-full-history/claims.md#c037).

Preserve a group's musical identity when it is reordered, instead of treating its new position as a different envelope or bus history. [History C040](docs/releases/0.5.4-full-history/claims.md#c040).

Apply post-group controls at host-frame boundaries and route shared group controls without unnecessary staging copies. [History C047](docs/releases/0.5.4-full-history/claims.md#c047).

Unify connection and routing gestures so the same pie interaction is used across oscillator, operator and parameter destinations. [History C055](docs/releases/0.5.4-full-history/claims.md#c055).

Use the same curve representation across waveform, LFO and response editing instead of maintaining unrelated curve systems. [History C065](docs/releases/0.5.4-full-history/claims.md#c065).

Support per-note pitch, pressure, volume, pan and timbre through the shared note-expression layer used by the host shell. [History C067](docs/releases/0.5.4-full-history/claims.md#c067).

Keep mono retrigger, legato and glide behavior in the new note engine, with bounded release and voice-stealing handling. [History C068](docs/releases/0.5.4-full-history/claims.md#c068).

Compile drawn waveforms into qualified shared-slope curves with derivative regularization, rather than shipping the rejected compiler experiments. [History C073](docs/releases/0.5.4-full-history/claims.md#c073).

Restore VA Vocode, Harmonic Stretch and Disperse processing up to the host Nyquist limit at 48 and 96 kHz instead of truncating the high harmonics. [History C076](docs/releases/0.5.4-full-history/claims.md#c076).

Keep Noise intrinsically single-lane and present it as a compact waveform-and-shaping card, without irrelevant pitch or unison controls. [History C083](docs/releases/0.5.4-full-history/claims.md#c083).

Give new Ripple operators zero starting speed, give Phase Bend useful starting depth and expose additive phase editing directly on operator cards. [History C094](docs/releases/0.5.4-full-history/claims.md#c094).

Expand additive unison to 1–16 lanes. Saved counts migrate, but old normalized DAW automation now addresses the wider range rather than the earlier 1–4 range. [History C096](docs/releases/0.5.4-full-history/claims.md#c096).

Keep persisted PCM from being normalized a second time when a stored source is restored. [History C108](docs/releases/0.5.4-full-history/claims.md#c108).

Present Grain, Rich and Spectral Loop as the visible Resynth algorithms. The old Sample algorithm remains a decoder compatibility value, not a newly advertised mode. [History C117](docs/releases/0.5.4-full-history/claims.md#c117).

Size prepared voice storage to the published source and avoid retaining unnecessary additive retirement state. [History C120](docs/releases/0.5.4-full-history/claims.md#c120).

Keep FilterTable's current product limit explicit: it addresses the first eight VA source slots, not all 32 oscillator slots, and its magnitude response is an approximation. [History C123](docs/releases/0.5.4-full-history/claims.md#c123).

Build FilterTable kernels on a worker and publish completed plans with clear, acknowledgement and failure handling rather than compiling kernels during audio playback. [History C124](docs/releases/0.5.4-full-history/claims.md#c124).

Keep ModalBank's mode state in a persistent SIMD-friendly layout rather than gathering and scattering each mode every sample. [History C126](docs/releases/0.5.4-full-history/claims.md#c126).

Persist distortion-curve edits with their module and publish prepared data only when the curve changes. [History C132](docs/releases/0.5.4-full-history/claims.md#c132).

Keep one processor per effect kind and preserve its audio state when the rack is reordered. [History C139](docs/releases/0.5.4-full-history/claims.md#c139).

Publish a fixed-size effects snapshot only when the edited rack generation changes, instead of having the audio thread read the locked editor document. [History C141](docs/releases/0.5.4-full-history/claims.md#c141).

Preserve the configured plugin identities, preset extension and legacy preset roots during the MOOSE host migration, with checked-in compatibility fixtures. [History C143](docs/releases/0.5.4-full-history/claims.md#c143).

Keep factory preset state intact in the host tooling rather than replacing the patch with default host-bank values. [History C144](docs/releases/0.5.4-full-history/claims.md#c144).

Keep keyboard auditions in view and retain the pre-audition patch so browsing can be dismissed without losing the original sound. [History C147](docs/releases/0.5.4-full-history/claims.md#c147).

Retain migration support for older KURV preset generations; the history appendix records the original external .kurv-to-.kurvy migrator separately from current loading behavior. [History C149](docs/releases/0.5.4-full-history/claims.md#c149).

Keep legacy additive variants and frozen host-bank numbering available while structural edits update the displayed names and hidden controls. [History C150](docs/releases/0.5.4-full-history/claims.md#c150).

Update the Matari-Access licensing integration alongside the host/editor migration rather than introducing a separate licensing system for each plugin format. [History C152](docs/releases/0.5.4-full-history/claims.md#c152).

Move CLAP, VST3 and standalone hosting to MOOSE and add the AU v2 integration for macOS. Format support in source is distinct from the artifacts actually published for a release. [History C154](docs/releases/0.5.4-full-history/claims.md#c154).

Share the same instrument, parameters, persistence and DSP between plugin formats and standalone instead of maintaining different synth implementations per host. [History C155](docs/releases/0.5.4-full-history/claims.md#c155).

Use a half-band decimator for two-times-oversampled group runs rather than the heavier generic path. [History C159](docs/releases/0.5.4-full-history/claims.md#c159).

Use four-times oversampling for offline rendering where the host provides an offline render mode. [History C160](docs/releases/0.5.4-full-history/claims.md#c160).

Provide a faster local edit/test loop and a focused operator-kernel harness; the engineering appendix retains the measured workloads and their limits. [History C164](docs/releases/0.5.4-full-history/claims.md#c164).

Use the workstation/shared CI controls and avoid duplicate CI executions for the same pull request. [History C165](docs/releases/0.5.4-full-history/claims.md#c165).

Update actual plugin build and packaging tooling to the MOOSE host stack, rather than treating an editor gallery as a plugin delivery. [History C166](docs/releases/0.5.4-full-history/claims.md#c166).

Keep three-platform release automation, verified archive metadata and manifest publication as an explicit delivery step separate from source integration. [History C167](docs/releases/0.5.4-full-history/claims.md#c167).

Retain signed/notarized macOS packaging tooling while distinguishing macOS trust status from unsigned Windows and non-applicable Linux signatures. [History C168](docs/releases/0.5.4-full-history/claims.md#c168).

Preserve the vendor DSP research archive, including negative results and bounded unknowns. Research about another synth is not a claim that KURV copies it or matches its performance. [History C169](docs/releases/0.5.4-full-history/claims.md#c169).

Retain the full optimization workstream ledger alongside the complete product history; documentation-only checkpoints and held trials are not counted as shipped features. [History C170](docs/releases/0.5.4-full-history/claims.md#c170).

Rebuild the low end and noise from your sample.

Draw pitch and volume curves. Add grit with distortion.

Keep a short part of the original attack.

Hover a preset and press Space to hear it. A line follows the sound across its waveform.

Try every feature for 28 days. No key or card needed to start.

Existing projects, presets and trial dates remain compatible.

Hovering a preset gives its editor keyboard focus.

Space previews the card under the pointer immediately.

Its waveform playhead follows preview playback.

Text editing and inactive license screens keep their normal shortcuts.

Existing KIKK projects, presets and trial dates remain compatible.

Renamed KIKK to KIK.

Start a full 28-day trial in the plugin. No key or card required.

Frosted activation backdrop.

Two RELAY plugins in one room now send and receive audio over LAN or WebRTC. Browser listeners hear both plugins together.

Browser listeners can name themselves. The sharing plugin shows each browser microphone and plugin return in a compact strip with its own gain, mute and level meter.

Separate input and output MUTE controls dim their meters when active. THRU controls whether local DAW input passes to the plugin output.

The plugin opens at a more readable size and waits for a pause or Enter before reconnecting after room or password edits.

The browser listen page shows the optional room password before joining and sends it with the first join request.

The RELAY product page now matches the plugin's Signal look, with clearer downloads, comparison and help sections.

Browser listeners have separate talkback gain sliders in the plugin's mic view, with live indicators and a 0 dB reset.

The plugin and browser use Matari's Signal look: lime, Silkscreen headings, Departure Mono readouts and the animated dot and chevrons. The plugin's changelog and settings panel offers a saved Standard appearance too.

The listen page keeps a compact content-sized card when mic mode and the room roster are visible in Firefox.

Built on MOOSE 7 (Matari's truce fork) instead of truce 6.3. Sessions and presets from 0.2.0 load unchanged.

An Audio Unit (AU v2) for macOS, in the same installer as the CLAP and VST3.

The meters and link status keep moving while the editor is left alone.

The editor scales with the window when you resize it.

The about panel's notes no longer overlap, and scroll when they don't fit.

Typing in the room and password fields works on Windows.

Includes MOOSE's archive and audio input routing fixes.

Rewritten from scratch: one small core, one plugin, one worker.

Internet rooms over WebRTC with Opus up to 510 kbps, adapting to the slowest listener under a ceiling you pick; lossless on a LAN.

Anyone can listen in a browser at relay.matari-audio.com/<room>, with their own volume.

Browser listeners can talk back with their mic; the plugin plays it and shows who is talking.

Nothing is sent over the internet during silence.

The buffer sizes itself to the network and resyncs in silence.

IN and OUT meters, each with its own fader.

The editor keeps its scale when reopened.

Windows, macOS (signed and notarized, Universal) and Linux.

The scope derives its added-peak tint from the selected theme and keeps it out of the red spectrum; monochrome themes use a neutral highlight.

VIOLET, white with a blue-violet accent, is the new default theme.

Analysis now sets real host latency, 21, 43, 85 or 171 ms at 48 kHz for Fast, Balanced, Fine and Ultra, and replaces the Engine, Timing, Adaptive and Lookahead parameters and the host meters.

Audio-to-MIDI conversion adds only detected notes; the beat-grid kick and hi-hat track on MIDI channel 2 is gone, and the plugin is about 10 MB smaller.

New configurations start the spectral view at a 2048-point FFT; saved choices are preserved.

Documented that REAPER on Linux must run with GDK_BACKEND=x11: on a native Wayland GDK backend REAPER crashes inside its own window layer when any plugin editor opens.

When recording storage cannot be written at all, BUFFR now retries saving less often instead of every five seconds, and reports the folder it tried to write so the problem can be found; the same failure is no longer repeated in the log.

Reports and diagnostics now name the graphics adapter, backend, device type and driver that drew the interface, and whether GPU spectral analysis is active, so display and Spectral problems can be traced to the driver that caused them.

WARPs use title-bar mode selection, a filled waveform on the left, and readable inside-value knobs on an LFO-style control rail. Brickwall belongs to Spectral; phase warps have their own category.

Distortion adds Amount drive alongside Mult and Mix, with horizontal and vertical skew sliders around its drawable transfer curve.

Distortion is a separate generator-stack module with a drawable transfer curve, a compact shape selector, Multiply repeats, horizontal/vertical skew, and Mix. Removed Bias and Stereo controls.

Waveshaper curve edits persist with the module and publish prepared data to audio processors only when changed; modulation uses the same transfer function shown by the editor.

Moved the envelope inside the purple group identity header. Envelope lines provide direct stage and curve editing without visible point handles.

Warp assignments use compact connection pies on the oscillator, with source-hover feedback and a centered assignment gesture on its waveform panel.

Separated general phase warps from VA harmonic low-pass/high-pass filters in the insertion menu.

Restored customized group headers and large pane labels. Group envelopes sit above the generators, with direct stage and curve editing, pointer values, and gradient fill.

WARPs use compact boxed cards with small previews, segmented controls, and a centered add button.

Compatible oscillators reveal an assignment target beside their content. Per-connection amounts stay in a compact side strip and follow host automation.

Independent WARPs rack with categorized insertion, compatible-source assignment, and resizable left and right panes. Shared warp amount multiplies each connection's own automatable/modulatable depth.

Modulation gestures now start actual drags and cancel consistently on Escape, outside clicks, and focus loss.

Added prepared Disperse/Tilt/Random and seven configurable spectral transform families, with exact zero-depth neutrality and a bounded 255-harmonic correction.

Generator-stack distortion provides six transfer types with Drive, Bias, Spread, Mix, and antiderivative antialiasing.

Group output controls follow the module chain, with a playback-derived envelope overview and responsive aligned rows. Removed the redundant group-header waveform preview.

Reduced repeated filter-coefficient bank copies; controlled dense-patch measurements preserve exact audio statistics. This stress workload still exceeds its callback deadline.

Groups own their per-note amplitude envelopes. One-group and multi-group patches use the same render path, and reordering preserves envelope and bus histories by group identity.

Source-native processors belong to their source and are edited in the left pane. Audio effects remain in the group signal path.

Admit supported native chains explicitly: one built-in VA Brickwall followed by an optional Phase Warp. Unsupported orders, source representations, spectral Warp, Tilt, Random, and Sync remain unavailable pending DSP qualification.

Rebuilt Settings around Input, Capture, Export, Appearance, and Performance, with License, Updates, Diagnostics, and Report inside one window. Stable accessible names for icon-only controls, consistent spacing, stronger headings, aligned icons, solid accents, readable slider values and FFT menus that close after selection, and compact native dialogs replace nested panels and uneven padding. Theme and spectral colors edit directly, save automatically, and reset to their original presets. Settings preserve valid saved choices across upgrades and merge changes between instances; new configurations default to icon-only toolbars, solid waveform fill, and two hours of history.

Added faster GPU spectral analysis and wavelet synchrosqueezing for clearer separation of nearby notes, plus GPU spectral selection where supported and CPU fallback. Faster parallel loading, reusable zoom detail, adaptive memory limits, Overview and Full detail modes, corrected frequency scaling and tile edges, stable selections, stronger narrow ridges, calibrated levels, and a wider Floor range improve analysis and display. Long recordings, compressed imports, processed previews, playback, exports, and undo use bounded storage; recovery survives plugin reloads, restores faster, and preserves unreadable data safely.

Improved recording and playback reliability: System Audio continues when the host stops processing, macOS capture handles formats and timing more reliably, and source changes and MIDI preview avoid interrupting other channels. Corrected quiet multichannel playback, true-peak normalization, streamed processing continuity, silent-range exports, Windows drag-and-drop, oversized host blocks, and shutdown behavior. Graphics setup, lost devices, Spectral reopening, and auxiliary-window commands recover more reliably, while background work avoids blocking recording.

Setup starts with activation, adds a final Make it yours step for theme, waveform, and spectrogram choices, and finishes with a three-second BUFFR-colored inward animation, animated logo, and reduced-motion support. Activate by key, start a trial, or use MuseHub in supported editions directly inside Setup or Settings. The License page shows a masked key, current device and active devices, with refresh and confirmed deactivation. Existing activations are preserved.

Preview is consistently named in updates and downloads, with installed and available release notes and scrollable history. Diagnostics show the complete available session log. Reports always include viewable diagnostics; the displayed snapshot is the one sent. Automatic crash reporting retains complete available incident evidence until delivery is confirmed, and more accurate graphics, memory, storage, and shutdown diagnostics improve troubleshooting.

Simplified editor and aligned responsive layout. Fixed CLAP state refresh, VST3 host interface discovery, and clipped rendering on resize. Windows and Linux CLAP/VST3 builds; Windows requires Microsoft Visual C++ 2015–2022 x64 runtime. Run the included Windows installer as administrator and restart Windows before scanning plugins.

The help backdrop is a plain dim veil instead of a blur, so the workspace behind the stage stays intact.

F1 over any part of a card (its header, a graph, a cell) lifts the whole card rather than a single region.

Every host parameter, the settings panel, the preset deck, the wave editor pencil, function toggle and table actions, and the quality selectors carry help text.

Filter cutoff, resonance, slope, morph and shape modulation now cover their real ranges, and filter mode changes stay continuous instead of clicking.

The OBJECT filter's modes are peak-normalised, so DECAY no longer doubles as a volume control and nothing comes out louder than the input.

The group envelope callouts read their true 0 ms to 20 s range and the pitch wheel range reads 1 to 96 semitones.

Waveform expression edits are bounded and can no longer overflow the compiled buffer; invalid edits keep the last valid wave playing.

The stereo pair of a diffused Rich resynthesis is now decorrelated instead of duplicated.

Audio and MIDI imports append cleanly with mixed sample-rate conversion, complete undo state, bounded multichannel disk use, visible progress, correct keyboard focus, and immediate waveforms; repeated exports reuse prepared files and remain reliable through Windows Explorer, asynchronous hosts, Wayland, XWayland, undo, cancellation, and editor closure.

Settings, Activity Log, Diagnostics, and Report panels are movable, resizable, scrollable, selectable, copyable, and accessible; reports retain bounded capture, renderer, Spectral, memory, import, and crash evidence, build IDs identify exact installs, damaged trials recover, and activation, support, and update downloads reject malformed responses.

BUFFR-V now ships as a separate experimental CLAP, VST3, and standalone download for Linux, Windows, and universal macOS, with its own plug-in identity and notarized macOS installer.

The experimental Vizia spectrogram now retains source tiles while the timeline moves and colors them on the GPU, removing the viewport-wide CPU recoloring that stalled playback and resizing.

Completed spectral analysis now redraws the Audio canvas immediately, and playback schedules spectrogram work ahead of the moving playhead instead of waiting for unrelated UI activity.

Spectrogram redraws now target the correct editor and stop cleanly when it closes, preventing stalled multi-instance views and redundant frame requests.

Partial spectral tiles no longer sample an empty neighboring column while recording or panning between analysis columns.

The route inspector shows destination and depth inline, and a source can be flipped between unipolar and bipolar from the inspector.

Dragging a source onto a target explains itself: vertical drag sets the depth, and invalid targets are named as such instead of silently refusing.

Ctrl snaps parameter drags to musically meaningful steps (semitones, cents, percent) on top of Shift for fine control and double-click to reset.

Oscillator cards show the tuning mode (SEMI, RATIO, EXP FM) as a clickable switch with matching cents, Hz and ratio readouts.

Pan-shape and spline editors: double-click a point to flatten its segment, double-click empty space to add a point, Shift for fine moves, remove and reset in the right-click menu.

New settings for modulation display and CPU: SHOW MODULATION CABLES keeps cables visible for every visible route, and AUDIO-RATE FAST or EXACT trades CPU against modulation quality.

Completed audio imports reveal the full appended waveform immediately, while the animated aurora keeps the lane visibly busy until the import finishes.

Audio imports now keep the waveform visible under an animated aurora until ready, block conflicting gestures during the handoff, and report the exact reason when a drag export cannot be prepared.

Timeline pan and vertical gain, frequency, and pitch controls now expose distinct values and actions to assistive technology.

Long recordings keep using conservative waveform summaries at zoom boundaries instead of redundantly rereading raw audio.

The editor stays idle when nothing changes, coalesces redraws during active work, and preserves native drag, accessibility, and graphics-recovery behavior.

Panel close buttons now expose their purpose to screen readers and desktop automation.

File-drop diagnostics now record background import progress so stalled imports can be identified without guessing whether the host accepted the drop.

Support reports include bounded current activity, correlate delayed crash artifacts more reliably, and finish background submissions safely before the host unloads BUFFR.

Auto, Full, and Low Power display modes now adapt to constrained, virtual, and software-rendered machines while preserving Full settings; Low Power uses a one-second passive refresh, a simple waveform, and disables Spectrogram and background Wet work, with performance controls available from FX.

Standalone closes without waiting for another audio callback, including before input starts and when JACK stops; MIDI activity is announced accessibly, linked inputs reconnect more reliably, and per-note expression stays attached to the correct repeated note; macOS crash reports retain memory-allocation evidence and support reports can be correlated anonymously.

Standalone closes without waiting for another audio callback; MIDI activity is announced accessibly, linked inputs reconnect more reliably, and per-note expression stays attached to the correct repeated note; macOS crash reports retain memory-allocation evidence and support reports can be correlated anonymously.

MIDI activity is announced accessibly, linked inputs reconnect more reliably, per-note expression stays attached to the correct repeated note, and Low Power bounds dense note and marker drawing; macOS crash reports retain memory-allocation evidence and support reports can be correlated anonymously.

macOS crash reports retain virtual-memory allocation and memory-summary evidence for diagnosis.

Crash reports can now be correlated with anonymous installation and system statistics without exposing raw hardware identifiers.

Right-clicking FX now opens performance, refresh-rate, Spectrogram resource, and background Wet controls.

First-run Capture setup now lets users choose whether offline processing is cached in the background, with clear memory guidance on hover.

With background Wet preparation disabled, selecting audio starts one exact preview with visible progress; enabling it also prepares reusable full-buffer previews.

Updating on Windows now requests permission, waits for the host to release BUFFR, replaces the standard CLAP and VST3 installs, and places the standalone app on the Desktop.

Updating on macOS now opens the signed, notarized BUFFR installer in Apple Installer.

Linux updates place the standalone app on the Desktop and request administrator permission only when an existing system-wide plug-in copy also needs updating.

First-run setup now uses two focused Capture and MIDI steps, with format help on hover and Bit depth beside History.

Global MIDI source and multi-controller linking now share one setup page with a clearer alternating device list.

Finishing setup now blooms into a brief BUFFR-colored Ready moment before revealing the recorder.

Dropped audio and MIDI now append at the end of their lanes, and one undo restores the complete pre-drop audio and MIDI state, including combined drops.

Audio drops target the selected channel, while All preserves BUFFR source-channel routing when available; imported MIDI keeps its embedded MIDI channels.

The drop target now highlights the affected lane and audio destination with a foreground dashed aurora overlay.

Linux installation guidance now lists the runtime libraries and graphics support required by the release package.

Platform guidance now states the Windows MIDI Services, Linux runtime-library, and macOS deployment baselines required for a reliable BUFFR install.

Global MIDI now relies on native sharing on current Windows 11 systems. Exclusive legacy Windows inputs should use Host MIDI from the DAW.

Extended plug-in validation now allows enough time for large multi-rate Windows validation runs to complete.

Settings now exposes locally published experimental releases as the Unstable update channel.

The current Nice Plug and Baseview editor lifecycle improves native window ownership, display scaling, and editor open/close behavior across CLAP, VST3, and standalone builds.

BUFFR now uses the current upstream egui rendering and input backend while preserving accessibility, native drag-and-drop, frame scheduling, and graphics recovery behavior.

Keyboard input uses the current cross-platform event model while preserving BUFFR's native window, display-scaling, and drag behavior.

Offline effect-analysis caches now rebuild safely from retained recordings after the experimental dependency update.

Experimental builds refresh the audio, graphics, resampling, analysis, and updater foundations for current platform compatibility.
