Practice Rack QA Checklist

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

Run Metadata

Short file: record a 5-15 second take; save, reopen, play back, and export it.
Long file: record or import a 30-60 minute practice take; timeline, playback, and cleanup remain responsive.
Chinese path: save presets, loops, and recordings under 测试素材/吉他练习/; reopen them after app restart.
Damaged file: open a truncated preset, loop, recording, or cabinet IR; the app shows a recoverable error.
Huge file: import a large IR or long recording near the documented limit; the app rejects or loads with visible progress.
Unsupported file: drop a random binary file onto preset, IR, or recording import; the app reports unsupported content cleanly.

44.1 kHz input/output runs without drift during monitoring, looper playback, and recording.
48 kHz input/output runs without drift during monitoring, looper playback, and recording.
96 kHz device mode either works or reports a clear unsupported/downsample message.
Mono input maps correctly to the rack and recorder.
Device disconnect during monitoring stops audio safely and lets the user select another device.
Buffer size changes do not leave the UI showing stale latency or a dead audio stream.

Select guitar input -> confirm input meter -> tune -> load a clean preset.
Load preset -> adjust noise gate, compressor, EQ, drive, delay, and reverb -> save preset.
Enable looper -> record loop -> overdub or replace -> stop -> clear loop.
Record a take over the loop -> play back -> export the recording.
Disable and reorder effects where supported; bypass state is saved and restored.
Confirm clipping, muted input, and silent output states are visible to the user.

No license: tuner, basic rack, looper, and recorder match the community feature set.
Valid online license: professional presets, advanced effect parameters, cabinet IR loading, and checkout license-key activation are available.
Activated license state: app launches with no network and preserves licensed features.
Tampered or wrong-product license: app rejects the license without deleting presets or recordings.
No network: input monitoring, tuner, effects, looper, recorder, presets, and local exports still work.

No console panic or unhandled promise rejection during connect -> preset -> effects -> looper -> recording.
Release notes mention any remaining driver, latency, IR, or device limitation.
Screenshots and help copy match the current UI labels.
