Frequently asked questions
Which HarmonyHub features need an account?
None of the instruments do: playing, the metronome, the tuner and recording all work without signing in. Music rooms, sharing and saving recordings to Google Drive need a free Google sign-in.
What can HarmonyHub not do yet?
It does not export video or MP3 files and does not connect to MIDI controllers. Recordings download in your browser’s audio format, usually WebM.
Are all features free?
Yes. Every instrument and feature on HarmonyHub is free to use.
