When something stops

Keep your work. Check the affected component.

Generation is unavailable

Check the selected engine and its device preflight. Do not treat installed packages as proof of usable GPU access. Imported audio can still be useful without a generator.

An audio change is not audible

Choose Render preview, wait for the saved render, then select the rendered comparison. Draft controls do not change the last saved audio.

A MIDI result sounds wrong

Transcription is a draft. Shorten the passage, check the source layer, and correct the notes against reference audio. A mixed Other stem may contain several instruments.

Your take seems missing

Check account identity, filters and Trash. Local libraries are separate. Avoid deleting local data or another app's model files while troubleshooting.

Still stuck?

Record the app version, macOS/device, selected component and exact action. Do not include passwords, tokens or private recordings in a report.
