Tab & Score Assistant QA Checklist

Use this checklist for each release candidate before publishing downloads or website copy.

Run Metadata

Short file: import a 5-15 second MP3, WAV, and FLAC; detection preview, tab view, editing, and export all work.
Long file: import a 30-60 minute file; analysis can be cancelled and the UI remains responsive.
Chinese path: open audio from 测试素材/扒谱/主旋律.wav; save edits and exports under the same path family.
Damaged file: import a truncated or invalid audio file; the app shows a recoverable error and does not create a corrupt score.
Huge file: try an oversized file near the documented memory limit; the app rejects or queues it with a clear message.
Unsupported file: import a random binary file renamed as .wav; the app reports unsupported media cleanly.

44.1 kHz stereo file imports, analyzes, edits, and exports correctly.
48 kHz stereo file keeps bar timing stable after analysis and quantization.
96 kHz file either processes correctly or reports a clear downsample/unsupported message.
Mono file analyzes without channel-routing errors.
Variable bitrate MP3 keeps transcription timing aligned after seeking and replay.

Import audio -> choose guitar -> review generated tab -> edit notes and positions -> export.
Import audio -> choose bass -> verify range, string choice, and exported result.
Import audio -> choose drums or score view where supported -> verify notation labels and playback alignment.
Correct wrong pitch, duration, string/fret position, bend/slide marking, and barline placement.
Quantize after edits and confirm it does not erase manual corrections unexpectedly.
Export MIDI, MusicXML, and PDF where enabled; open each file in an external app or viewer.
Reopen a saved project and confirm audio reference, edits, instrument view, and export settings are preserved.

No license: detection preview and tab/sheet viewing work, while editing, quantization, and export show the Professional gate.
Valid online license: MIDI, MusicXML, PDF, advanced editing, and quantization are available as documented.
Activated license state: app launches with no network and preserves licensed features.
Tampered or wrong-product license: app rejects the license without deleting local projects.
No network: import, detection where local, editing, saved projects, activated license state, and local exports still work.

No console panic or unhandled promise rejection during import -> instrument -> result -> edit -> export.
Release notes mention any remaining transcription accuracy, format, or export limitation.
Screenshots and help copy match the current UI labels.
