Cueing

Now you know how to beatmatch, but it's still difficult to do.
A handy feature to do it more easy is to use a CUE point.

A CUE point is a point in the song where something begins (beat, vocals, etc)
Play a song and when you are at the place which you want to use set the point by pressing [SET].
Alter the point if it isn't exact at the place you want by pressing [<<] or [>>]
Now you can jump back to that position by pressing [CUE]

If you used [<<] or [>>] the Stop button is flashing and you here the point repeating constantly.
No press the Play/Pause button to pause on your point.
Press Play/pause again to start playing.

You can also use the Cue function for looping.
When playing the track press [SET] at the exact point you want.
Press [CUE] x beats later to loop back directly.
This needs some practice and don't get angry if it doesn't work the first time.

NOTE: Sometimes the player doesn't loop back directly and needs to scan to the point of the track.
This to bad encoded MP3 files.
