The track I played is not saved in the performance history (HISTORY). Why not?

When 60 seconds or more have elapsed since the track was loaded, it is registered in the history. Only tracks analyzed by rekordbox are registered.
In the following cases, tracks can't be registered:

■For tracks on USB storage devices
・ Insufficient free space on the USB storage device.
・ The USB storage device is write-protected.
・ The track was loaded from [FOLDER].

■For tracks in the cloud or on streaming services
・ The AlphaTheta account you're logged in to has a Free or Core plan on rekordbox.com.
*If you search or pause a track after playing it, the track will be registered 60 seconds after the search/pause.
