VirtualDJ DJC Mk4
i) Analyze your music files’ BPM rates
The first time you display your list of music files in a DJ software
application, the Beats Per Minute rate is not calculated: we strongly
recommend that you analyze all of the music files you intend to mix with in
advance, so that you can then read the BPM (Beats Per Minute) rate in
the browsing area, to load only music tracks matching the BPM rate you
need.
To analyze the music files in a directory:
- select the music file(s) in the music list and right-click with your mouse
(or on Mac with no right-click on the mouse, use Ctrl + mouse click): a
pop-up menu lets you select the action Scan for BPMs to analyze the
music files.
ii) Run the BPM analysis in advance, not during a party!
T
he BPM analysis takes time (1 hour for 120 music files), so starting the
BPM analysis of your complete library just before a party is a very bad
idea. You should therefore carry out the analysis in advance: it’s easy, as
you can analyze your complete hard drive and you don't need to remain in
front of your computer while VirtualDJ DJC Mk4 is analyzing the music
files. Please note that the BPM analysis requires a lot of processing
power, so mixing while VirtualDJ DJC Mk4 is analyzing your full library is
not recommended, since your computer will not respond as fast as it
should.
The analysis is generally accurate, but occasionally the BPM rate
calculated is not correct: sometimes the BPM calculated is double or half
of the actual BPM rate (the BPM analyzer may count only 1 beat out of 2
in a track, or identify an intermediary sound within a beat as the start of
