Operation Manual

Part of VirtualDJ’s BPM Engine is to calculate the Computer Beat Grid (CBG) of the track.

However, in rare cases, when the BPM and the CBG is not correctly calculated, you can easily

correct both manually by right-clicking on the appropriate BPM button for corresponding

track.

There are several methods for correcting the BPM and the CBG:

Using the "Copy from other deck" button on the Edit BPM tab is

the simplest method. Using a track where the BPM is already

known click on the button to copy that BPM to the track which

has the unknown BPM.

And as previously covered, using a keyboard shortcut for the

“beat_tap” action or left-clicking on the BPM button for the

corresponding track, you can manually tap out the beat of the

track and the CBG will adjust accordingly. However, you may

need to adjust the CBG by using the Phase slider or +/- ¼

buttons.

Alternatively, an anchor method can be used. From the Edit

Grid tab, Click on "beat tap" button while the track playing, in

order to approximate the BPM.

Then, pause the track and advance the track to the first

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 between 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.

** For more information on how the CBG is used for beat matching see the

section about the Rhythm Window later in the manual.
