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.
