Your curves, on your devices.
Optional sync covers personal EQ presets only.
Enable sync
Use the same iCloud account on your devices and enable preset sync in Auris on each one. The feature is initially off.
What gets synchronized
Personal presets, including per-channel settings saved in a preset, are shared. Music, playlists, Crossfeed and active audio settings are outside its scope.
Timing and deletions
Changes may take time to reach another device. Deleting a preset while sync is enabled deletes it on other devices too. Turning sync off preserves existing copies.
