Respect creators’ rights
You need permission to upload, adapt and distribute your music and rehearsal tracks. Buying a score or holding a performance licence does not necessarily cover rehearsal recordings; check with the publisher or rights holder. The tool grants no rights to compositions, lyrics or arrangements.
Your instrument packs
Upload only packs you’re licensed to upload and use. Commercial libraries may forbid extracting or re-uploading samples. Packs stay private; shared pages contain rendered tracks, not the pack.
Recorded parts (Beta)
Upload only recordings you made or have permission to use, and get each performer’s consent before processing, converting or sharing their voice or playing. Voicing changes and Convert to notes (Beta) create derivatives of those recordings and the underlying song, so the same rights apply. You keep ownership of your recordings; we don’t use them to train AI. Recordings are processed in your browser and saved only to your own Google Drive if you choose.
Check before sharing
Exports can miss details. Check parts, key, timing and balance in Preview and finished tracks. Note warnings can flag intentional repeats.
Beta singing voice
This is conventional synthesis, not a live singer or generative AI. Pronunciation and timing may be rough; instruments give more reliable rehearsal audio.
Sharing limits
Open links and playlists can be forwarded; page passwords restrict access but cannot prevent audio copying. Project edits do not publish automatically. For account-saved projects, choose Update listening page, then Share as link again to update the same link. Saved playlist names and selections can also be updated at the same link.
Keep your originals
Note fixes leave your original file unchanged. Keep the score and a downloaded project backup in case browser data is cleared.
