The 'Beat-O-Matic' is a tool that allows you to capture, analyze, and synchronize your favorite music into the game. The data can be used as BGM during game play.
If it's a song that you have already synchronized, you can just play it on the Xbox 360 media player and the game will sync with that song.
You can select music from the following sources:

1. Music which already exists on the Xbox 360 Hard Drive.
2. External music player or a memory device connected by a USB cable.
3. Music stored in a computer connected to the network. (DLNA)

When analyzing your music, the Beat-O-Matic runs through the 3 steps listed above.

●Analyzer --
As the music is played using the Xbox 360 music player, the BPM of the song is analyzed and saved.
●Tester --
This screen displays the fine-tuning of the resulting BPM value and the synchronized starting point of the song as you listen.
●Manager --
Here you can save, view, or delete the synchronized data of your songs.

1. At any time during the game, press [GUIDE button] and open the Xbox 360 Guide.
2. Play the synchronized data song with the Xbox 360 music player.
3. Press the [B button] to close the Xbox 360 Guide. The song will automatically synchronize.

Also, please note the following:

1. In an Xbox LIVE match, the game will always use the default BPM even if you choose to use a song which you have synchronized.
2. If you play a song that is not synchronized, the game will start with the default BPM (120.0bpm).
3. If you use more than one song's synced data, then once the song changes, the game will automatically match the tempo of the new song.

For example, if you create an album which only contains synced music, you can play the entire album with the Xbox 360 music player

This game has two types of Leaderboards: 'Generic Leaderboards' and "Beat-O-Matic Leaderboards".
When you play with default music, your scores will be sent the "Generic Leaderboards".
If you played your personal song by pressing [GUIDE button] during game play, the results will be displayed in 'Beat-O-Matic Leaderboards'.
In addition to the points you've obtained, the song name, artist name, album name, and BPM information can be viewed on the Leaderboards.
