How can I set the cue points in music tracks with Mobile DJ Mix?

Mobile DJ Mix software includes an AutoCue function in the analysis of the sound track to :
- define a Cue In point (Cue In = the moment where the song playback starts in a DJ mix, which is the moment where the software detects a regular beat)
- define a Cue Out point (Cue In = the moment where the song playback ends in a DJ mix, which is the last point where the software detects a regular beat)

The analyzes of the Cue In / Cue Out point is in general
- relevant for music with a fixed beat and for dance / techno / country / rock music,
- irrelevant for music with changing rhythms, as for example classic music, pop songs starting with vocal solos, slow electronic music and in general music whose rhythms are far from techno/dance...

The solution for the music tracks with bad cue points is for the user to define one's own Cue In / Cue Out points:
1) load the music file
2) browse in Mobile DJ Mix software (with the slider over the waveform) at the point of the waveform where the user wants to place the Cue In point
3) Click on the "In" button of Mobile DJ Mix software on the deck where the song is loaded (left and right of Automix button on the software screen), to define the point which will be the Cue In point,
4) Click on the button with a triangle down on Mobile DJ Mix software to set the Cue In point,
5) browse in Mobile DJ Mix software (with the slider over the waveform) at the point of the waveform where the user wants to place the Cue Out point (the end of the music playback)
6) Click on the "Out" button on the deck of Mobile DJ Mix software where the song is loaded (left and right of Automix button on the software), to define the Cue point will be a Cue Out point
7) Click on the button with a triangle down on Mobile DJ Mix software to set the Cue Out point
8) Once the Cue In and the Cue Out points have been saved for the music track, save the Playlist with the button "Save".
If the user doesn't save the playlist after changing the cue points, the new cue points won't be saved.
