BPM & MIXING GUIDE
*************************
As there are many new users to VirtualDJ, I think this guide is needed.
Most info here have been posted before, but collected the info for one easy-to-use guide for
new users.
VDJ get the BPM right for most songs, and specially songs that are in a regular beat, such as
house, disco, dance etc. But as many other programs, finding the right BPM for hiphop, r'n'b,
and some pop/rock music can be tricky.
Having the right BPM for all files are essential for VDJ to work right, for example when it
comes to looping, beatmixing etc.
It's some work to do this, but definitively worth it
It's easy to check if a file have right BPM or not. Try playing a song, and try loop with 4 or 8
beats. If it sounds like a perfect loop, the bpm is right.
There are several ways to find the right BPM, and here are 3 good ways :
-manual tapping the beat
-using autobpm and enter value into VDJ
-using Mixmeisters bpm-program and enter the value into VDJ
There are two values to keep in mind when adjusting songs in VDJ:
(1) finding the right BPM, secondly , (2) aligning Computer Beat Grid to fit under the beats.
----------------------------------------------------------
INTRO: ALL MUSIC CAN BE BEATMIXED
--------------------------------------------------
First a little theory
(thanx jukesy from the atomixmp3 forum):
"All music is made up of repetitive loops and patterns. For example most sequencers and
music tools for music creation such as Acid Pro, Fruityloops etc.. use loops to create a
final song. These patterns, the majority of the time, stay the same length for the whole
tune, i.e the tempo of the tune does not change. (unless you are trying to mix with
Aphex Twin or other artists that bend the rules of music making)
The basis of mixing two tunes together is matching these pattern lengths. Every song
has a tempo, beats and bars. All you have to do is work out (by listening to the tune) the
length of the pattern. Once you have the length of one pattern for one tune you need to
match the second tune's pattern to the same length.
A pattern is basically when some part of the music repeats itself."
So, all music can be beatmixed, all music can be made to a prefect loop.. you can even
beatmix a hiphop song with a pop song, or even rock song, its all about finding the right
bpm / cbg, and it works like a charm
So, music is repeated patterns – usually 4 beat pr pattern
Also, keep in mind that hiphop/r'n'n/drum&bass will remove or change one of those
beats, but it's still 4 beats pr bar – it's just that you can't "hear" it often, but it feels like
its there..
(from jukesy)
"By removing the bass drum every other beat and by adding in some extra
snares/symbols etc... you end up with a drum and bass beat.
…by removing more beats .. you end up with a hip -hop beat etc"
-------------------------------------------
FINDING RIGHT BPM & ALIGNING CBG
-------------------------------------------
there are some tools that can help you finding the right bpm.
(1) AUTOBPM gets the right bpm for almost any song. Choose a range (50-100 for
slowers songs or 75-100 for hiphop etc)…
When u see the pattern (grapics) in autobpm move in a steady manner, the bpm is right.
(2) use Mixmesters bpm program, for many files and even directories. (WARNING – use
this program only for new ripped files, and not for files that are already scanned/used by
VDJ, because sometimes this program can change the size of the file, and you must
rescan the file in VDJ, loosing comments, cue-points etc)
(3) Or you can manually tap the beat by right-clicking the song in VDJ, choosing "edit
bpm" for the song you are playing.
Now, enter the value from autobpm/mixmeister bpm into the song in VDJ. It will not be
always perfect, but close. (if manually tapping, the value is already there)
Next is to adjust for perfect values. Right-click song and adjust bpm with arrows so that
beat-bars have the same pattern as cbg dots, and are aligned (one dot under each beat
bar) CBG are those dots you see under the waveform (computer beat grid) and are very
important to be aligned for VDJ's beatmix engine, loops, samples etc.
If the cbg dots and beat bars are not aligned but stay in a pattern, use the cbg arrow to
move the cbg dots too (you will find these arrows in a pro skin, for example Fruit's
Pioneer 700 skin)
Look towards the middle and end of song. If beat-bars and cbg stay aligned together,
everything is perfect. If they start to move a part, play the song, and slowly adjust bpm
with arrows to make it fit cbg.
Also, for a perfect mix, cbg should be aligned to first beat of measure (the big cbg dot).
"..By ensuring that the first beats of your patterns are matched and continue to be
matched every four bars/repetition of pattern then your mix will sound in time and
match.."
ALWAYS MATCH THE START OF A PATTERN OF ONE TUNE TO THE START OF A PATTERN
OF ANOTHER otherwise you will end up with breaks/vocals/melodies/tones all in the
wrong place and the mix wil sound terrible.
The first beat of the measure/pattern is almost always the first beat of the song. Make
sure the big cbg dot is aligned to the first beat. Not always in hiphop / r'n'b songs,
because they have a cool intro or something. So, the first beat is almost always where a
new verse starts, see if the big dot is repeated at every verse start, if not move the big
dot to that place…
That's all folks

update on bpm analyse
**************************
as there has been a development in using tools to help find bpm, here is an update on the “finding the right” bpm part of the guide above…. With the new VDJ database updater tool, all cue, comments etc in VDJ database will be kept, even if the filesize changes with the Mixmeister bpm tool!!
Please note that you still have to adjust for cbg to fit beat in many songs, and also make the big cbg button be on the first beat. And the bpm from Mixmeister tool is not always perfect so a little adjustment for bpm might also be needed!
So please read the guide above for the best performance for VDJ and your mixes!
This is essential to make mixes, loops, samples etc work perfect!
INSTRUCTIONS ON USE VDJ DATABASE UPDATER:
1) Run the MixMeister tool, and export the results to .txt file;
2) Load the database updater program
3) Enter the path to the MixMeister file (box 1), and the path to VirtualDJ's database (box 2);
4) Enter a new file name (3rd box) for the new database (the updated one);
5) Click on the 1st button ("Update Database").
(This WILL NOT overwrite your current database)
6) If you want to automatically 'overwrite' the database, click on the button ("Backup and replace Database"), which will create a backup of your current database, and it will replace the database with the new one.
This tool can be found in the effect download
