Mozzy supports several bands on one device at once — useful if you play in more than one Mozivio-managed ensemble.
To add another band, go to More > Accounts and use the account switcher — it lets you add a new band the same way you first logged in (by email), without signing out of the one you already have. Each band keeps its own separate login, sheet music, events and tasks; nothing is shared between them.
To switch which band you're currently viewing, open the same account switcher and pick one. Notification settings are kept per band too — see Changing your notification settings — so muting one band's reminders never affects another.
