MANUAL BPM CORRECTION

The CBG is calculated automatically when a track is loaded for the first time. VirtualDJ uses
powerful algorithms to calculate the BPM and the CBG of music (1 of 2 algorithms ca n be
chosen - a fast but effective algorithm which works
well for techno and house, and a slower algorithm
which is effective on any type of music).

H owever, in some rare cases, the CBG is not correctly
positioned on the beats of the song. In this case, you
can easily carry out a manual correction.

Click on the button.

There are several methods to correct the BPM and
the CBG:

The simplest method is to beat-match the track with
u nknown BPM with a track whose B PM is already
known, then clicking on "copy from other deck".

Alternatively, the anchor method can be used.

Click on "beat tap" button while the track playing, in
order to approximate the BPM.

Then, pause the track, advance the track to the
downbeat (first beat), and click on "First anchor". Then
advance to the upbeat (second beat), and click on
"Second anchor". Check that the number of beats
displayed corresponds well to the number of beats
b etween the two anchors.

Then go further in the music, and repeat the "second
anchor" operation if you notice that the beats and the
CBG shift. Normally two or three anchors should be
enough to obtain an accurate CBG.
