Support matrix

Evidence as of: 5 November 2026. This hand-maintained page summarizes recorded runs of the generic export layer's RAVET Delay example on release/0.1.0 through 628af5d, plus the local validator rerun in the docs/CI work package. Evidence Synth and the macOS architecture work (based on eb4d2f5) are recorded separately below. It is not a certification of every product, host version, device or deadline. Format adapters remain prototypes. Earlier 0.0.1 reference checks remain in work status and host validation; they do not qualify the new adapters.

Only named host runs appear in the first table. A validator or adapter test does not establish host support. “Not recorded” means no such evidence is recorded here, rather than a failed test. Host point versions not recorded in the source entry are explicitly left unspecified.

Format × platform: named host runs

Every run below is dated 5 November 2026. Each evidence link names its dated WORK_STATUS entry.

Format macOS arm64 Windows 11 x64 VM Arch Linux x86_64
CLAP REAPER 7.82/macOS-arm64 on macOS 27.0.1: fixed/synced renders, edits/readback and project recall (run, merged-harness reruns) REAPER 7.82/x64, WaveOut: same harness, three passing runs (run) REAPER 7.82/linux-x86_64, JACK: same harness (run, rerun)
VST3 Ableton Live 12 Suite on macOS 27 arm64 (point version not recorded): manual fixed/synced exports match the strict sample checker (run) REAPER 7.82/x64, WaveOut: edits/readback, project recall and fixed/synced renders, three passing runs (run) REAPER 7.82/linux-x86_64, JACK: same harness, three passing runs (run)
LV2 REAPER 7.82/macOS-arm64 on macOS 27.0.1: edits/readback, project recall and fixed/synced renders (run) REAPER 7.82/x64, WaveOut: same harness, three passing runs (run) REAPER 7.82/linux-x86_64, JACK: same harness (run, rerun)
AUv2 Logic Pro on macOS 27 arm64 (Logic version not recorded): manual fixed/synced bounces, typed values, editor reopening and saved-project recall (run); REAPER 7.82/macOS-arm64 on macOS 27.0.1: edits/readback, project recall and fixed/synced renders after the transport-residue fix (run) Not applicable Not applicable
AAX Pro Tools 26.4, macOS arm64 (OS version not recorded in this entry): manual fixed/synced bounces, mouse editor use; keyboard typing failed in this run; after the decision 0286 fixes characters work and click-away commits, while Return/Escape stay Pro Tools shortcuts (run) Provisional, owner decision on 5 November 2026: Windows bundle built and adapter-checked; not run in Pro Tools for Windows (build/checks, decision recorded in release plan) Not applicable

The REAPER harness checks 48 kHz offline master-mix renders, 63 host checks per run, two project recalls and exact echo positions/mix/silence. It does not exercise live playback, custom editors or automation. The VM's WaveOut and Linux JACK settings identify the environment; they do not qualify a device. The macOS merged-harness CLAP rerun also records one initial startup timeout.

The manual Live exports match the strict checker after unwarping the clip and typing exact values; editor lifecycle and session recall were not recorded. Logic's bounces include the metronome, so checks used exact delay sample positions and amplitudes rather than a whole-file checker pass. In Pro Tools, echo timing and sync were measured, but the strict checker fails amplitudes because the dragged/reset values differ from exact targets; the fixed default also has a small one-sample split from normalized parameter precision. The release plan's previous blanket “sample-exactly” wording must not be read as a strict checker pass for these manual runs.

macOS x86_64 under Rosetta 2

5 November 2026: Apple M4 Pro, macOS 27.0.1 (26A434), REAPER 7.82/OSX64 launched with arch -x86_64. Thin x86_64 and universal Delay bundles built in all five formats; every shipped image's slices were checked. These are translated x86_64 runs on Apple silicon, not native Intel hardware evidence. The architecture receipt records exact builds, wrappers, logs, SDKs and limitations.

Format x86_64 validator / adapter result REAPER 7.82/OSX64 result
CLAP Pinned clap-validator 0.4.1 (152b982): 33 passed, 0 failed/warnings, 11 skipped Universal bundle: 63 host checks and all three strict 48 kHz renders passed
VST3 SDK 3.8.1 validator: 47 passed, 0 failed Universal bundle: 63 host checks and all three renders passed; per-process sandbox excluded system VST3 directories after an initial startup-scan timeout
AUv2 Exact signed bundle's contracts and private process-local auvaltool 1.10.0 passed, preserving original identity Thin x86_64 component: 63 host checks passed, but strict renders failed (echoes 2,048/3,072 frames late; transport sample residue, decision 0294). After the fix, the universal bundle passed 63 host checks and all three strict renders (run)
AAX AAX SDK 2.8.0; RAVET bundle checker passes mono/stereo, parameters and state Not applicable to REAPER; Pro Tools x86_64 and Avid validator not run
LV2 Actual-module smoke 46 checks, 0 failures; CTest 2/2; lv2_validate 0 errors Universal bundle: 63 host checks and all three strict renders passed

All successful host runs preserved the normal REAPER resource directory. The disposable configs selected Mac mini Speakers at 48 kHz/512 frames to avoid an audio-init modal; hardware sends were removed. No live-device claim follows. Optional lilv was disabled for universal/non-host builds because the installed Homebrew library is arm64-only; x86_64 lilv and lv2lint not run. Universal validators also ran their arm64 slices. arm64 AU uses system registration, which can select an installed same-identity product; its exact artifact is independently covered by in-process contracts. The x86_64 AU validator uses explicit process-local registration of the new component.

Editor runs on Windows and Linux

Separate from the render harness above: tools/reaper-validation/editor.py opens the Delay's web editor in a floating REAPER 7.82 FX window, sets a parameter from the host, closes and reopens the editor and removes the plug-in with its editor open, in a disposable configuration (run).

Format Windows 11 x64 VM (WebView2 156) Arch Linux x86_64 (XWayland)
CLAP Renders; host edit shown; close/reopen/remove; quits cleanly. Editor input not exercised Renders inside REAPER's plain (non-XEmbed) child window; host edit shown; XTest click and drag reach the host; close/reopen/remove
VST3 Same as CLAP Same as CLAP
LV2 Same as CLAP (WindowsUI) Same as CLAP (X11UI)
AAX Synthetic AAX host only (ravet_aax_check --editor, real HWND); no Pro Tools Not applicable

The Gain example's asset-served page also rendered in REAPER's CLAP host on both platforms. These are scripted observations in one host per platform: no keyboard input, accessibility, other DAW, display scaling above 100 % or real-time claim.

Standalone audio and MIDI

The DW-303 standalone application (its own repository), built on RAVET's StandaloneWindow, Audio/MIDI popup, ravet-device and ravet-midi-device. Windows/Linux runs were on 5 November 2026 (receipt; Windows MIDI receipt).

Platform Audio output MIDI input
macOS arm64 Owner report: exercised; device not recorded Owner report: exercised; device not recorded
Arch Linux x86_64 (PipeWire 1.6.9) ALSA PipeWire Sound Server (alsa:pipewire) into PipeWire's Dummy Output null sink; capture of the app's stream verified ALSA sequencer Midi Through Port-0 (14:0); notes produced the expected pitches in that capture
Windows 11 x64 VM (26100) WASAPI Speakers (High Definition Audio Device) (emulated HDA); WASAPI loopback capture verified the demo pattern WinMM RAVET Loopback B, a Windows MIDI Services in-box MIDI 2.0 loopback configured on the VM (notes sent to RAVET Loopback A); notes produced the expected pitches in a WASAPI loopback capture, and no sound with no MIDI input selected

No hardware output on Linux, physical MIDI device, latency or callback deadline was measured. Both MIDI inputs are software loopbacks. On Linux the window's rendered content and a clean quit were not confirmed. On Windows the window rendered (screendump) and quit cleanly with saved state.

Validators and adapter checks (separate from hosts)

All entries below were recorded on 5 November 2026. These are results from the cited receipts. The macOS 0.4.1 row is a new local rerun for this docs/CI work package; other rows summarize earlier receipts.

Format Platform and tool Recorded result and evidence
CLAP macOS arm64, clap-validator 0.3.2-127 Delay: 33 passed, 0 failed, 11 skipped; skips include f64, preset discovery, port configurations and note tests (run, policy regression)
CLAP macOS 27.0.1 arm64, pinned official clap-validator 0.4.1 (152b982) Locally rebuilt Delay: 33 passed, 0 failed, 0 warnings, 11 skipped; not a hosted CI run (run)
CLAP Linux x86_64, clap-validator 0.4.1 (152b982) 33 passed, 0 failed, 11 skipped, 0 warnings; repeated seven times (run)
CLAP Windows 11 x64 VM, clap-validator 0.4.1 (152b982, source-built with static CRT) 32 passed, 0 failed, 12 skipped; denormal timing warning in 3 of 7 runs; the additional skip is Linux-only scan-rtld-now (run)
VST3 macOS arm64, Steinberg SDK 3.8.1 validator Delay, Gain and mock: 47 passed, 0 failed each; mock CTest 1/1 (run, merged Delay rerun)
VST3 Linux x86_64 and Windows 11 x64 VM, SDK 3.8.1 validator Delay and mock: 47 passed, 0 failed on each OS; Windows mock contracts also run under Wine (run)
AUv2 macOS 27.0.1 arm64, AU Validation Tool 1.10.0 and RAVET component checks; AudioUnitSDK 1.4.0 Effect/instrument/MIDI-effect mocks pass auval; merged Delay passes auval -v aufx QFKS TYDS and in-process state/render/automation/retained-view checks (mock run, Delay run)
LV2 macOS arm64, LV2 1.18.10, lilv 0.28.0, sord 0.16.22 Delay/Gain/mock adapter, lilv and render checks pass; lv2_validate reports 0 errors; real Cocoa editor smoke included (run)
LV2 Linux x86_64; Windows 11 x64 VM, LV2 1.18.10 Linux CTest 4/4; Windows mock 100 and Delay smoke 32 checks with 0 failures; Windows CTest 2/2 under Wine. lv2_validate reports 0 Turtle errors. No Windows lilv; lv2lint not run (run)
AAX macOS arm64, AAX SDK 2.8.0 and RAVET checks Mock CTest 2/2; Delay mono/stereo rendering, parameters, state and off-screen editor check pass. Avid validator not run (run)
AAX Windows 11 x64 VM, AAX SDK 2.8 and RAVET checks Delay mono/stereo, eight parameters, rendering and state corruption checks pass; mock passes; unsigned. Avid validator not run (run)

Windows bundles in these receipts were cross-built on Linux using cargo-xwin and a static CRT. Native MSVC builds are not established by them. Hosted CI is configured separately and has not run for this change.

Evidence Synth — 5 November 2026

The deterministic instrument is a separate product from Delay. The receipt records exact build commands, failed attempts and scope. Every passing REAPER case checks stereo 48 kHz samples throughout four renders: CC response, 32/0 latency readback and PDC-aligned onsets, finite click decay and a second-instance MIDI route.

Format Linux x86_64 REAPER 7.82 macOS 27.0.1 arm64 instrument evidence
CLAP Four renders PASS; normal config unchanged clap-validator 0.4.1: 34 pass, 0 fail/warnings, 10 skips; actual CLAP ABI sample/MIDI tests pass. REAPER startup timed out before script; no host render evidence.
VST3 Four renders PASS, including controller-derived CC level and note output route; normal config unchanged SDK 3.8.1 validator: 47 pass, 0 fail; real-product adapter-class MIDI/audio/timing CTest 1/1. REAPER skipped because of known third-party VST3 scan stall.
LV2 Four renders PASS; normal config unchanged CTest 4/4 including actual instrument Atom MIDI/audio/latency, lilv; lv2_validate 0 errors. REAPER startup timed out before script; no host render evidence.
AUv2 Not applicable Actual component: three note/CC, MIDI-output-byte/offset, audio/tail and latency-notification cycles PASS; auval 1.10.0 PASS. No Logic instrument run.
AAX Not applicable Actual unsigned bundle synthetic checker PASS: two MIDI nodes, CC audio, note output and latency notification. Finite tail verified in audio; SDK 2.8 has no native tail report. No Avid validator or Pro Tools instrument run.

No Windows instrument run is recorded. REAPER's second-instance audio render cannot by itself exclude host MIDI-through; actual CLAP/AU/AAX/LV2 fixtures check generated bytes/offsets; a VST3 real-product adapter-class fixture checks controller/note conversion, output offsets and preserved IDs. The processor declares a finite 96-sample default tail (64 with lookahead off). CLAP, VST3 and AU expose timing to hosts; LV2 exposes latency only and AAX has no tail report here. These checks do not qualify a physical MIDI/audio device, custom editor, polyphony or live deadline.

Known limits

The feature registry and generated catalogue contain the exact per-adapter limits; see also plug-in exports, VST3, AUv2, AAX and LV2.

Maintaining this page

Keep this page hand-written: the WORK_STATUS receipts include qualifications, partial manual checks and missing versions that cannot be inferred from a feature's implemented/prototype status. When adding evidence, retain the date, product, architecture, host/version, checked scope and a stable receipt link. Keep validators separate and change the evidence-as-of date only after review. The documentation checker validates local file links; semantic claims and anchors require review under maintenance.
