1   Welkom

Beatlock Technologie is trots om u de DJ Mix Pro Handleiding voor te stellen.
Dit document zal je helpen om je vertrouwd te geraken met DJ Mix Pro. Als je dit helemaal gelezen hebt zal je het mixen en afspelen van muziek in een makkelijke manier verstaan. Live DJing zal ook mogelijk zijn als je de correcte kabels hebt.
Vroeger moest je veel apparaten hebben zoals: meerder cd spelers, platenspeler, versterker en boxen en je moest vele knopjes bedienen.
Nu kan je makkelijk mixen maken met juist een muis klik.

toc

2   Inleiding tot mixen

Wij zeggen niet dat DJ Mix Pro de beste mixen maakt want, professionele DJ’s gebruiken hun hart en gevoelens ook.
Maar wij denken dat DJ Mix Pro "de meeste" mixen beter kan dan een gewone random mixer, de manier waarop sommige gebruikers mixen en DJ mix pro  maakt redelijk goeie mixen als je het een klein beetje hulp geeft.
Mixen is niet echt moeilijk als je geen expert bent. U moet gewoon muziek maken op een aangename manier.
Hier zijn de basis regels.

toc

2.1   Non-stop muziek

De belangrijkste regel in mixen is non-stop. Wanneer veel liedjes klaarstaan om te afspelen dan moeten de liedjes elkaar opvolgen, hetzelfde volume en overlappen aan je uiteinden van de muziek.

toc

2.2   Beats

Beats tonen het muziek tempo aan.  Ze zijn meestal op gemaakt van gewone drum slagen, maar kunnen ook opgemaakt zijn uit instrumenten noten als er geen drum slagen zijn.
De beats kunnen makkelijk gehoord worden in de meeste dans muziek zoals Disco, Dance, Rock, ... Het is Boom Boom Boom in Techno of meer discreet tching tching tching in Jazz.
Een doel van mixen is de mensen aan het dansen houden, dus hun ritme verstoren is niet meer nodig. U werk is een slimme volgorde te maken. Dit is "u" werk, en DJ mix pro kan jouw niet vervangen voor dat .

toc

2.3   Beats Per Minuut

BPM staat voor Beats Per Minute. Het is een getal dat u het muziek tempo aangeeft.
Een lied dat precies 2 keer per seconde Booms geeft zal 120 BPM hebben. Dj’s gebruiken BPM om de opeenvolging van liederen te bepalen doordat die een gelijkaardige tempo hebben.

toc

2.4   Cross-Fading

Wanneer overlappen 2 liederen elkaar tijdens een mix? Als de mix op het eerste liedeinde voorkomt, zal u de volume moeten verlagen tot nul, om een fade out te maken.
Hetzelfde als de mix bij het tweede liedbegin voorkomt, zul u de volume moeten verhogen, dit is dan een fade in.
Fade in en Fade out zijn belangrijk in mixen. Tussen Fade in en Fade out, is de tijd waarin beide liederen  in de mix samen spelen.

toc

2.5   Gelijkmaken van de beat

De Beat gelijkmaken is een DJ techniek dat bestaat uit 2 liederen die dezelfde beat hebben tijdens de mix. Het publiek heeft dan het gevoel dat het hetzelfde lied is. De beste DJ’s vertragen of versnellen een van de 2 liedjes en houden het zo een paar seconden.
Het uitvoeren van dit vereist manueel heel wat techniek, maar geeft zeer interessante mixen.

toc

2.6   Eigenschappen van DJ Mix Pro

DJ Mix Pro staat u toe om gemakkelijke mixen uit te voeren, zelfs het gelijkmaken van de beats.
U kunt mixen in real time, snel bewegen met uw muis, al het werk manueel doen.
Maar u moet niet . Wij stellen eerder voor, de mixen " off line " voor te bereiden ,gebruik makend van hoofdtelefoons alzo luisterend voor te bereiden, terwijl andere liederen op de luidsprekers afspelen.
Laat enkel Dj Mix Pro het vervelende deel (fade in, Pitching, fade out) doen terwijl u zich op het creatieve gedeelte concentreert (dat lied dat daarna afspeelde, hoe lang de mix te maken, de fades). U kunt uw off line mixen proberen gebruik maken van een hoofdtelefoon. DJ Mix Pro zal dan de mixen reproduceren die u gecreŰerd hebt wanneer de mixtijd gekomen is!
Deze methode staat u toe je zeker toe voelen, uw keuzes mixend/spelend off line, en het programma het moeilijke deel laten doen. Het helpt u een succesvolle huis DJ te worden.
Zelfs als u geen live DJ speelt, is de DJ Mix Pro nog goed voor het afspelen van muziek thuis of in milieus zonder DJ’s zoals bars, aerobic lessen of openbare gebeurtenissen. Als u Dj Mix Pro gebruikt met de default settings geeft het programma nog altijd redelijke resultaten, het publiek word soms zelfs verrast door het veranderen van lied waarbij ze niets gemerkt hebben.
Het laatste populaire gebruik is de productie van compilaties. De registreerde versie van Dj Mix Pro is ook zeer goed bij het maken van 75 minuten Cd’s  die kunnen worden gebruikt om een audio cd (die een extern brandprogramma gebruikt)  te vullen.

3   Installeren van DJ Mix Pro


toc

3.1   Bestanden

De installatie is makkelijk te installeren. Kies een andere plaats als de installatie plaats u niet geliefd is.                                          Niets word ge´nstalleerd in het Windows register en in externe submappen, zodat de uninstallatie ook makkelijk verloopt:             ofwel gebruik je het uninstallatie programma of delete enkel de installatiemap.
De uitgave van DJ Mix Pro is samengesteld uit verschillende bestanden, a.u.b  wijzig de originele uitgave niet. DJ Mix Pro kan niet onafhankelijk werken.                                                                                                                                                                       
De voornaamste bestanden zijn:
  • Verwerkingseenheid folder: waar Beatlock data bestanden (.blk files) opgeslagen zijn
  • Talen folder: internationale gestanden
  • Plugins folder: visualization en dsp Plugins
  • Htmldocs folder: documentatie folder

Alle data bestanden (m3d, m3v, blk) zijn text bestanden en zijn compatible. Ze veroorzaken geen problemen wanneer u het programma upgrade.

toc

3.2   Licentie

Als je een licentie gekocht hebt dan kan je demo ontgrendelen gebruik makend van de licentie data bestand.
Volg de instructies die je ontvangen hebt en geniet van het onbegrensde eigenschappen van het programma:
  • Onbeperkte mixen
  • Onbeperkte BPM analyses
  • Opslaan van geluid naar (een) bestand(en)

toc

4   Muziek bestanden

DJ Mix Pro werkt met bestanden die op een harde schijf staan. De bestanden kunnen ook (in een netwerk computer staan, maar niet op internet) of op een ISO CD ROM, maar wij stellen voor dat je de bestanden vanaf je harde schijf afspeelt.
DJ Mix Pro leest geen audio cd’s.

toc

4.1   DJ Mix Pro passende bestand formaten

DJ Mix PRO kan veel bestand formaten aan, en maakt sommige ook.
Hier zijn de passende bestand formaten:

toc

4.1.1   Muziek formaten

Mp3 bestanden: alle mp3 bestanden worden ondersteund
Ogg vorbis bestanden: alle vorbis bestanden worden ondersteund
Wav bestanden: simpele wav bestanden worden ondersteund (uncompressed, no loops). Meeste Wav bestanden zijn zo.
Wma bestanden: niet beveiligde wma bestanden worden ondersteund.
Andere muziek bestanden (voc, raw...) worden niet ondersteund.

toc

4.1.2   Playlist formaten

M3u bestanden: zijn winamp playlist bestanden. Dit bestand formaat is veel veranderden kan altijd nog groeien, maar DJ Mix PRO kan de meeste m3u bestanden laden.
M3v bestanden: zijn DJ Mix Pro playlist bestanden. Dit bestand formaat word gebruik om playlist te laden en te bewaren met al the mix gegevens.
M3d bestanden: zijn DJ Mix Pro databank bestanden. Dit bestand formaat word gebruikt om databank bestanden te laden en te bewaren.

toc

4.2   Zoeken en Inbrengen van bestanden

De eerste taak van DJ Mix Pro gebruiker zal het programma een paar muziek bestanden geven zijn. Dit kan worden gedaan in de databank of in de playlist.

toc

4.2.1   In de databank

In de databank |||||einde van vertaling word zo vlug mogenlijk geupdate||| you can directly use the Windows explorer and your mouse, drag and drop some music files or song lists into the database window.
You can also have the database search for files (music files and song list files) under a given folder hierarchy.
Or you can have the database load specific files, either music files or song list files.

toc

4.2.2   In de playlist

In the play list you can directly use the Windows explorer and your mouse, drag and drop some music files or song lists into the play list window.
You can also send selected items in the database window to the playlist.Or you can have the play list load specific files, either music files or song list files.
Files loaded directly from the play list will be inserted in the database as well.

toc

5   Playlist

The play list is the core of DJ Mix Pro. It is the list of songs which are queued to play and mix.

toc

5.1   Foto van de playlist

The play list displays 4 columns. Columns are simpler than in the database because no search information is needed here.
Columns can be resized (thus hidden) according to your needs and the program will remember the column sizes.
The database displays 10 columns. Columns are taken from the ID3 tags, file name, time length and BPM once computed.
Play list window screenshot

toc

5.1.1   Muziek titels

The title is taken from the ID3 tag.
If both ID3V1 and ID3V2 tags are present ID3V2 overrides ID3V1.
If no tag is present, title is taken from the file name.

toc

5.1.2   BPM

DJ Mix Pro will try to compute the BPM for every file in the database (see Beatlock Analysis chapter).
If you are using the demo version, DJ Mix Pro will try to compute the BPM for the first 11 files loaded only.
Before computation occurs, the BPM displayed will be “???”
During computation occurs, the BPM displayed will be “…”

toc

5.1.3   Mixen

This column tells you if this mix (as currently defined) will be a beat matching mix or not. If no beat matching mix is possible you can see the reason by switching to ”headphones listening” mode.

toc

5.2   Beheren van de playlist


toc

5.2.1   Importeren vanaf de databank

Songs can be imported from the database. See «Database: Sending to play list». Songs imported from the database are considered new and take their mixing settings from the default mixing settings (See Mixing songs: Default mixing settings)

toc

5.2.2   Direct toevoegen van bestanden

Dropping or opening a .m3v file appends to the current play list. Each song’s mixing settings are also reloaded from the m3v file.
Dropping or opening m3u files or music files also adds to the play list. Files added this way are new and take their mixing settings from the default mixing settings (See Mixing songs: Default mixing settings).
All files directly added to the play list are also added to the current database. It merges the songs with the current database, adding the new music files to the ones already there.

toc

5.2.3   Opslaan van een playlist

If you want to save the play list as is, including the mixing settings, save the play list in a m3v file.
By default the play list is NOT automatically saved to autosave.m3v when the program stops, but you can turn this on.
Be careful to save BEFORE playing because the default playing mode automatically removes the songs from the playlist that have been fully played.

toc

5.2.4   Lied informatie exporteren

If you want to save the play list song names, artist and length (to print it for example), export the play list in a txt file.
Again be careful to export BEFORE playing.

toc

5.2.5   Geluid exporteren naar cd (voor geregistreerde gebruikers)

If you want to burn a mixed CD, here is how to proceed.
Burning an audio CD requires you to provide your burning software with 70 minutes or so of wav file(s).
Each file will be a track on the audio CD. You can have a single track, but it is generally much better to have one track per song.
This section explains how to produce the wav file(s) that you need in order to burn, not how to burn them, because this is the responsibility of the burning software.

First you will need 800 MB of disk space.
Then you need to have the play list completely setup, mixes already defined and checked (using the ”headphones listening”  mode is a good idea). You might also want to check the playing length in the statistics, so that you don’t have more music mixed time than your CD can contain.
When this is done, and BEFORE playing, you need to go to the options window, sound output tab.

· Check that the primary soundcard is mapped to both channels of any available soundcard on your system… “Default” is fine(you want to make a stereo CD).
· Check the “save sound to file box»
· Don’t check save as mp3
· Check save one file per song if you want a separate file for each song or leave unchecked for a single wav file containing the entire playlist mix .
· Enter the base file name. This is the tricky part, because base file name IS NOT JUST A FILE NAME but rather the complete path and file name, possibly using metacharacters.
If you input just c:\mixedcd\track, wav files will be generated like this:
  • c:\mixedcd\track_001.wav
  • c:\mixedcd\track_002.wav
  • c:\mixedcd\track_003.wav
  • ….
You can use metacharacters to get intelligent file naming: %a for artist name, %t for title, %f for original file name, %% for percent.
If you input c:\cdtodo\song\(%a) - %t, wav files will be generated like this:
  • c:\ cdtodo\song\(toto) - africa.wav
  • c:\ cdtodo\song\(police) - message in a bottle.wav
  • c:\ cdtodo\song\(kiss) - I was made for loving you.wav
  • ….
Now in the Misc options tab, you must turn off «Repeat mode». You might want to also turn off «Auto remove after play».
When done, hit OK to save the changes.
Then in the play list window, start playing. Wave files will be produced while the sound is playing. Let the program play the play list entirely. If you stop the sound you will have to play from the start again.
When the entire play list has finished playing, go back to options and turn off the «save sound to file box» and hit OK. The wav files should be all created.

toc

5.2.6   Verplaatsen van liederen

Push the up or down buttons Up Icon Down Icon to move the songs selected in the play list. Or just drag the selection up or down.

toc

5.2.7   Verwijderen van liederen

Hit the delete button Delete Icon (or shortcut defined for this action, by default control-D) to remove all selected songs from the play list. This does not delete the actual song file but removes its reference in DJ Mix Pro play list. This does not delete the song reference in the database either.

toc

5.2.8   Onderzoeken en veranderen van muziek eigenschappen

Each song has physical properties, like the mp3 ID3 tags, the length, the Beats information, …
Hit the properties button Properties Icon (or shortcut defined for this action, by default control-P) to open the song properties window.
You can modify the Beatlock data if you need to (double the BPM / divide by 2 the BPM, shift by ½ beat), clear the Beatlock data.
You can tag song files in this window. If you had selected several songs, you can even tag multiple files (except for title tag). In this case, fields displaying “(multiple values)” will be left unchanged.
You can modify the mixing settings for the songs in this tab. If you have selected several songs, you can modify mix settings for all the selected songs. In this case, fields displaying “(multiple values)” will be left unchanged.
This is not however the most convenient place to change an individual mixing setting. You should read the ”headphones listening” mode chapter to learn an easier way to setup an individual mix.

toc

5.3   Afspelen van muziek


toc

5.3.1   Starten van de muziek

Just hit «mix with next» button Mix with next Icon and the first selected song will start playing. If no song is selected, the first song will start playing.
You can also double click on the song you want to play.

toc

5.3.2   Manier van afspelen

Once playing has started, songs will be played in sequence. A mix will occur between every song after the first.
By default, once a song has completed playing, it is removed from the play list, but you can change this behavior in the options.
You can also choose (under options) to have a repeating play list, mixing the last song with the first one.

toc

5.3.3   Stoppen van geluid

If you close the song currently playing, it will stop the sound with no mix.

toc

5.3.4   De overgang forceren

You can force song transition in 2 ways:
If you double click another song while playing, it will immediately stop the currently playing song and start the new song. This is not a graceful way to force a transition but it is the quickest way. You can also force a mix to occur immediately, which is nicer but longer. See «Mixing song with next» and «Mixing song with selected».

toc

5.3.5   Koptelefoon methode

All songs in the play list can be heard in headphones, and mix can be heard offline, while speakers are playing.
Select the first song to mix in the playlist and hit the «Send to headphones» button Headphones Icon.

toc

5.4   Mixen van liederen

The real power behind DJ Mix Pro resides in its easy mixing capabilities.

toc

5.4.1   Manier van mixen

Whenever a transition between songs occurs, either because you triggered it or because the mixing time has come, the following events occur:
  • The second song is loaded and displayed in a new window a few seconds before the mix. Playing position is set to the begin position in the new song.
  • The new song starts playing and performs its fade in.
  • The old song performs its fade out and disappears.
Now, if a Beatlock mix was possible and requested, during the time where the mix occurs, the program changes the tempo of the new song and slightly moves the begin position so that the beats of both songs matches. Tempo of the new song will then smoothly go back to normal.
Mix beahvior drawing

toc

5.4.2   Omgeving van mixen

All mixes are controlled by a few parameters taken from the properties of the 2 songs (see Play list: Examining and setting song properties):
First song properties:
  • Stop at
  • Fade out length
  • Mixing length
Second song properties:
  • Start at
  • Fade in length
  • Pitching length
Advanced properties also control these behaviors:
  • Use volume normalization
  • Perform a beat matching mix
  • Perform or don’t perform fade in / fade out

toc

5.4.3   Standaard omgeving van mixen

New songs added to the play list (except songs loaded from a m3v file) will take their properties from the Options window, Songs default tab.
You can change the song’s default before adding new songs, but once in the play list, you have to use the song properties window or ”Headphones listening” mode to modify the mixing settings.

toc

5.4.4   Zelf de controle over nemen

You usually have to do nothing to perform the mix. Everything is time event driven and the mix will occur when the playing position reaches stop at minus mixing length.
But you still can decide to start a mix immediately if you want to.
Just hit «Mix with next now» Mix with next Icon and the next song in the play list will popup. The mix will occur within a few seconds.
You can also force a mix with another song: select it in the play list and hit «Mix with next now» Mix with next Icon while pressing the Control Key key.

toc

6   Geluid uitvoer

DJ Mix Pro is designed to work with one or two soundcards. It is recommended that you use headphones when doing live DJing, although this is not mandatory.
In the options window, sound output tab, you can choose the soundcard for the play list output (Primary soundcard) and the soundcard for ”headphones listening” mode output (Secondary soundcard).

toc

6.1   One soundcard, no headphones

In this mode, everything played in ”headphones listening” mode will play on the speakers. This implies you don’t use headphones while DJing.
Map both primary and secondary to both channels of your soundcard (this is the default).
One sound card, no headphones

toc

6.2   One soundcard and headphones (mono)

In this mode, the soundcard output must be split in 2 mono channels. This will require you to make or buy an audio “doohicky” (a Stereo Y-Adapter).
This device is composed of a male stereo 3.5mm jack you plug into the soundcard on one side, and of 2 female stereo 3.5mm jacks on the other side. On these 2 jacks, one is the left channel of the soundcard and one is the right channel.
You plug your headphones into one and the hi-fi cable into the second.
Map the “primary soundcard” to the left OR right channel (your choice) and the “secondary soundcard” to the remaining channel.
One soundcard, using doohicky
Dohicky howto

toc

6.3   Two soundcards and headphones

This is the preferred mode. You have one soundcard dedicated to the (hi-fi) speakers and one to the headphones.
Buying a 2nd soundcard is not really expensive and is worth it if you plan to DJ a lot.
Map the “primary soundcard”to the first soundcard on your system and “secondary soundcard” to the other soundcard on your system.
Two soundcards

toc

6.4    One soundcard with 2 outputs and headphones

This is also the preferred mode. Using a 5.1 soundcard you have one output dedicated to the (hi-fi) speakers and one to the headphones.
Map the “primary soundcard”to the FRONT output on your soundcard and “secondary soundcard” to the REAR output on your soundcard.
One 5.1 soundcard

toc

6.5   Tuning the sound output

The soundcard plays continuously, buffers, that are built and sent by DJ Mix Pro.
Buffers are prepared in advance, covering by default ½ second of sound.
If your machine is slow and attempts another parallel activity, the soundcard can run out of buffers before DJ Mix Pro gets enough CPU cycles to prepare and send more buffers. You then hear glitches.
You can overcome this by playing with the sound output options. Increasing the buffers will make DJ Mix Pro less responsive but more tolerant to CPU bursts of activity.

toc

7   Headphones listening mode


toc

7.1   Objectives

The term “headphones listening” mode can be misleading because the sound is not in headphones if you choose the «One soundcard, no headphones» configuration.
The «headphones listening mode»  mode is designed to see, listen to and modify individual mixes.

toc

7.2   Usage

Once you have defined the playlist order, you can see and control all the mixes using the ”headphones mode” windows.
Select the first song to mix in the playlist and hit the «Send to headphones» button Headphones Icon .
Not all buttons are available if you have two songs loaded in ”headphones mode”, because you are restricted to the mix between these two songs.
You can then go from mix to mix forward or backward.
Close the ”headphones mode” windows when finished.
2 headphone listening  windows mixing screenshot


You have visual information of the beat awareness of the program in the bar drawn on the bottom of the black zone.

  • Green zones are beat aware zone corresponding to the BPM displayed in the main window list.
  • Purple zones are zones with BPM different to the BPM displayed in the main window list. Look at the local BPM info (in red) to know the local BPM.
  • Red zones are zones with no beat detected.

toc

7.2.1   Setting playing limits

You can set the points where the song will start and stop.
If needed, pause the song using Pause Icon .
You can have fine control on the playing position cursor on a paused song using the rewind Rewind Icon and forward Forward  Icon buttons :
Once a song BPM is known, what we call the interval unit is exactly one beat. Otherwise, this interval unit is half a second.
Clicking, you move the position 10 seconds
Clicking while the shift key key is pressed, you move the position 8 interval units
Clicking while the control key key is pressed, you move the position 1 interval unit
Clicking while the alt key key is pressed, you move the position 1/8 interval unit


Move the playing position cursor to desired start position and hit the «Start here» button Start here Icon .
Move the playing position cursor to desired stop position and hit the «Stop here» button.Stop here Icon

toc

7.2.2   Setting target volume

You can set the target sound volume for the 2 songs. That means the volume that will be set at the end of fade in. Just adjust the volume cursor.

toc

7.2.3   Setting lengths

You can set the fade out length and mixing length on the first song and the fade in length on the second song. Just play with the cursors.

toc

7.2.4   Requesting beat matching mix

You can request the mix to be a beat matching mix Request Beatlock Mix Icon or not Don’t request Beatlock mix Icon . Toggle the behavior clicking on the star button . If this is possible, the icon will display a smiley face. Otherwise the icon indicates that a beat matching mix is not possible.


toc

7.3   Trying the settings

Hit «Listen to fade in» (left Listen to fade in Icon ) in the second window to listen to the mix fade in only.
Hit «Listen to fade out» ( right Listen to fade out Icon ) in the first window to listen to the mix fade out only.
Hit «Listen to mix with next»Listen to next mix Icon in the first window or «Listen to mix with previous»Listen to prev mix Icon in the second window to listen to the full mix between the 2 songs currently displayed.

Retry your mix until you’re satisfied with it. The mix will happen on the primary output exactly the same way you heard it on the secondary output.

It might happen that beatlock mix is not possible. Look at the status icon to know why.
If BPM differ too much, you might have to change your playlist order if you still want a Beatlock mix.
If the icon says there are no beats in one of the song, you will have to move the fade in or out in the green zone
Retry your changes until the icon changes to happy face
Here are Beatlock mix statuses :

beatlock icons One of the 2 songs failed to beatlock, so no beatlock mix
One of the 2 songs is not beatlocked yet
Okay, Beatlock mix ready
Wew, BPM differ too much
No beats around ending pos of left song
No beats around starting pos of right song


toc

7.4   Navigating from mix to mix

You can navigate from mix to mix, in the order defined by your playlist.
If you hit «Listen to mix with next»Listen to next mix Icon in the second window, you will hear the next mix (second song becomes first and and the following song in the play-list is loaded as second).
If you hit «Listen to mix with prev» Listen to prev mix Icon in the first window, you will hear the previous mix (first song becomes second and and the previous song in the play-list is loaded as first).

8   Database

The database window is not mandatory. You can close it if you don’t want to use it. But it is a very useful tool when live DJing.

toc

8.1   Benefits

The database window is used to manage your music files. It is designed to handle many of them (several thousand songs can be put there) and quickly sort or find the songs you are looking for.

toc

8.2   Database display

The database displays 10 columns. Columns are taken from the ID3 tags, file name, time length and BPM once computed.
Columns can be resized (thus hidden) to suit your needs and the program remembers the column sizes.
Database window screenshot

toc

8.2.1   Database song titles

The title is taken from the ID3 tag.
If both ID3V1 and ID3V2 tags are present ID3V2 overrides ID3V1.
If no tag is present, title is taken from the file name.

toc

8.2.2   Database BPM

DJ Mix Pro will try to compute the BPM for every file in the database (see Beatlock chapter).
If you are using the demo version, DJ Mix Pro will try to compute the BPM for the first 11 files loaded.
Before computation occurs, the BPM displayed will be “???”
During computation occurs, the BPM displayed will be “…”

toc

8.3   Managing the database songs


toc

8.3.1   Adding files to the database

Dropping a .m3d file or music files into the database window appends to the current database. It merges the songs, adding the new music files while leaving the ones already there.
Searching for files takes all supported files (m3d, m3u, m3v, wav, mp3, ogg, wma) in the folder hierarchy you select and adds the files to the database.
Using «Open a database» you can add all selected files to the database. You can add .m3d files or music files directly by dragging and dropping them into the database window. You can add one file or several files at a time.

toc

8.3.2   Saving a database

You can save the current database to a m3d file. By default the database is automatically saved to autosave.m3d when the program stops, but you can turn this off.

toc

8.3.3   Moving songs in database

Push the up or down buttons Up Icon Down Icon to move the songs selected in the database. Or, just drag the selection up or down.

toc

8.3.4   Resetting songs order

Hit the «record this order» button Record this order Icon to renumber the database lines. This is useful for saving a custom order after sorting.

toc

8.3.5   Deleting songs in database

Hit the delete button Delete Icon (or shortcut defined for this action, by default control-D) to remove all selected songs from database. This does not delete the actual song file but removes its reference from the DJ Mix Pro database.

toc

8.4   Using the database songs


toc

8.4.1   Sending to play list

The purpose of the database window is to send songs to the play list queue.
Hit the «Send to play list» button Send to playlist  Icon (or shortcut defined for this action, by default control-B) to append the selected songs to the play list.
You can also double click on songs to send them to the play list.
Songs enqueued in the play list will be played in order, but you can change this order and the way the mix is performed until that particular mix is executed.

toc

8.4.2   Sorting songs

Click on any column title to sort the songs in the database. The first click will sort ascending but a second click will sort descending.
If you want to sort using several keys (for example by BPM then by title) click on the columns in reverse key order (for the example, click title then click BPM)

toc

8.4.3   Finding songs in a huge database

If you want to look for a song, you can open the search window, type your search string and hit search.
Search will show you the cell matching the input string. Hitting next will search down the column, then the next column, top to bottom and so on, until next match is found.
When searching for a match, only letters and numbers are significant. It is not useful to type spaces and characters because they are ignored.
A quicker way to search is to put the input focus on the list (click in the list once).
Then directly type your search string without spaces. The selection will move to the next match. Hit the space bar to go to next match.

toc

8.4.4   Examining songs properties

Each song has physical properties, like the mp3 ID3 tags, the length, the Beats information, etc…
Hit the properties button Properties  Icon (or shortcut defined for this action, by default control-P) to open the song properties window.
You can modify the Beatlock data if you need to, (double / divide by 2 the BPM, shift by ½ beat), or clear the Beatlock data.
You can tag song files in this window. If you had selected several songs, you can even tag multiple files (except for title tag). In this case, fields displaying “(multiple values)” will be left unchanged.

toc

8.4.5   Quick listening to songs

If you hit the quicklisten button Quicklisten Icon , you can listen to the selected song in the headphones. This allows you to identify a song if tag information or file name are not explicit, without having to stop the sound from the speakers.

toc

9   Beatlock Analysis


toc

9.1   Definition

DJ Mix Pro computes in the background the beats and BPM of all song files it meets.
This task is called Beatlock analysis or beatlocking.
This is done automatically in the background, you do not have to bother about beating on your keyboard.
Beatlock mix (beat matching mix) becomes possible whenever one song and the next song in a row are succesfully Beatlock analysed, and are BPM compatible (10% of tempo difference or less, configurable in the options dialog) as well. This what is shown in the mix column.

toc

9.2   Behavior

DJ Mix Pro will take all files in the order they were loaded and check if there is already a Beatlock data file (blk).
If yes, it will load data from this file. Otherwise it will perform a full file analysis. The analysis takes some time (lets say about one minute per song), but when completed the results are stored permanently in a blk file.
The BPM column shows the activity being done on files. If “…” is displayed, file analysis is being done. If a BPM or “BAD” is displayed, analysis or data load occurred and nothing more will be done on the file, unless you delete the Beatlock data.

... doing Beatlock analysis
--- song does not need/use Beatlock analysis
BAD analysis of song failed
??? song not analysed yet


toc

9.3   Control and options

You may turn off the Beatlocking if you think you do not need it.
You can stop all analysis (if any) by selecting the «Stop beatlocking» menu item.
Resuming will occur when you select «Start beatlocking» menu item.
You may also turn the «Do beatlock analysis on songs» off in the global options dialog before you actually load songs.
The BPM search is done between lower and upper BPM limits found in the options. Avoid giving BPM ranges that are too large because DJ Mix Pro can confuse BPM and its double or half.

toc

10   Miscellaneous features


toc

10.1   Equalizers

There are 2 levels of equalizers in DJ Mix Pro. The master equalizer is global and is used for all songs. You can access it in the action menu.
Even if you close the window, it is still used until you reset all track bars to 0 Db.
Each individual song in the play list can also have a local equalizer. Local equalizer settings are stored in the m3v files as well as mixing settings.

toc

10.2   Secure mode

There is a special playing mode in DJ Mix Pro (Secure Mode) that asks for a confirmation anytime the user selects on option which can cause the sound to stop. It can help avoid catastrophic glitches caused by accidental actions on the part of the user. This is especially useful with mouse pads.
Try it and use it if you like it.

toc

10.3   Statistics

The statistics window computes the playing time. If there is a selection in the playlist, total length of that selection is reported. If no selection, total length of on all songs in the playlist is reported. It also computes the total playing length (which is different since there is overlapping when mixing).

toc

10.4   Sound pitching

Pitching digital sound is not easy. We have tried 3 different algorithms for pitching, none of which is perfect.
You have the choice between
  • «Classic sound stretching», that doesn’t eat much CPU but changes the tonality. Plus introduces a slight perturbation in very high frequencies.
  • «High quality stretching» does the same but consumes more CPU and fixes the high frequencies problem.
  • «Pitch scaling» doesn’t eat much CPU, doesn’t change the tonality, but produces some reverberation effects with slow tempos.
We left the choice up to you.

toc

10.5   Transporting Beatlock data files

If you wish to use DJ Mix Pro on several computers and want to share Beatlock data and music files, you must leave the blk files next to the music files.
You can then copy the blk files ( or access via network share) as well as the music files.
To do this, check the “Laave beatlock data near mp3 files» option

toc

10.6   ID3V2 tags handling

ID3 V2 tags are something newer, more complex and more fragile that ID3V1 tags.
It takes also more time to read them.
This is the reason why we choose to turn this processing off by default.
If you want to use these tags, turn the option on.

toc

10.7   Command line options

You can run the program with command line arguments (on the DOS prompt).
The most commun usage is to give file names as arguments. The program will load them in the playlist.
You can also use these options to control the program from a script.
Some options are designed to override the options of the options window.

Usage : DJMIXPRO [ options ] [mp3_file1] [mp3_file2] ...


If files are provided on the command line, play will start immediately.
Options :
  • --play
  • --noplay
  • --nodbscreen
  • --dbscreen
  • --noautoload
  • --exitwhendone

--play : Will force the player to start.

--noplay : prevent player from starting.

--nodbscreen : Will prevent Database screen from showing.

--dbscreen : Will force Database screen to show

--noautoload : Will prevent autosaved playlist to load and save. (overrides the «Options dialog» value).

--exitwhendone : Program will exit after all songs have played. (but beware , will not work if «Loop mode» option is enabled)

toc

10.8.2   Visualisation plugins

If you want to have nice animations in synchronisation with the music, you can install some visualisation plugins in the plugins folder.
Feature deprecated ( discarded).

11   Options reference



Here are a lot of interesting options plus default values that are applied to songs loaded in the playlist.

toc

11.1   Song defaults tab

Song defaults tab
Do beatlock analysis : new songs will have their «Try Beatlock Mix at end» property set to this. Means they will be Beatlock analyzed and Beatlock mixed if possible.

Do volume normalization : new songs will have their «Use normalization» property set to this. Means that songs will be all played at the same perceptive volume.

Do fading detection analysis : new songs will have the «use fading detection» property.

Do fade in : new songs will have this «Fade at begin» property set to this. Songs will perform a fade in when starting to play

Do fade out : new songs will have the «Fade at end» property set to this. Songs will perform a fade out before stopping.

Do pitching done on both songs : new songs will have this value for «pitching done on both songs» property.

Mixing length : new songs will have this «mixing length» property.

Fading length : new songs will have this «fading in/out length» property.

Pitching length : new songs will have this «pitching length» property.

Playing begin position : new songs will have this «start at» property.

Playing end position : new songs will have this «stop at» property. This field accepts negative values, that are relative to the end b of the song.

All time length text controls accept this syntax :

mm:ss.xxx

where mm are minutes, ss are seconds and xxx are milliseconds.
valid inputs examples follow :
100 100 seconds
1:40 100 seconds
100. 100 seconds
1:40.00 100 seconds
.40 40 ms


toc

11.2   Beatlock options tab

Beatlock options tab
Use smart limits : allow song start and stop limits to move (in the limit defined by the smart limit maximum) while trying to perform a Beatlock mix.

Smart limit maximum : maximum move of start or stop of a song when allowing smart limits.

Limit BPM detection to : upper and lower bounds of BPM search. Limiting BPM width search avoid some BPM bad guesses and helps DJ Mix Pro to Beatlock better.
Tip : it’s a good idea not to let upper limit be greater than ( lower limit * 2 ) since BPM detection easily mistakes with half or double BPM.

Allow tempo adjustment of percent : here you define the pitch change limits. See a mix occurs for more details.
Tip : Allowing changes more than 8 % usually leads to ugly results.

toc

11.3   Sound output options tab

Sound output options tab
Sound out options : Many of the items on this tab will be grayed when sound is playing. You can change them at silence time only.

Use Direct Sound : sound output will use DirectSound instead of the WinMM module. If DirectSound is not available on your machine, the item will remain grayed.

Soundcard updates per second : number of times per second the soundcard receives sound buffers. If you choose too many times per second (more than 12 for example) your sound system will become CPU stress sensitive and may play dirty sound, but having many updates per second makes the program more reactive because you reduce the commands delay.

Number of soundcard buffers : choose the number of buffers the program uses. If you choose too few buffers, the program might become out of buffers if another program uses much CPU, but having few buffers makes the program more reactive because you reduce the commands delay.

Primary soundcard : soundcard to use for songs in playing mode. It can be any of your system soundcard.

Primary mapping : channels of the primary soundcard to use for the primary output.

Secondary soundcard : soundcard to use for songs in headphone mode. It can be any of your system soundcard.
Tip : a second soundcard to add in the system or a 5.1 soundcard to replace a one output soundcard is less than 40 USD on a standard PC ...

Secondary mapping : channels of the secondary soundcard to use for the secondary output.

Save sound to file : when checked, sound played on primary card is saved to .wav files. This button will be grayed if sound is already playing or if you are using the demo version.
Beware : this will work well only if you have mapped primary soundcard on BOTH channels.
Also note that if you have mapped secondary soundcard on the same physical soundcard as primary, you’ll save everything playing in headphone mode as well. In this case you should turn on saving only when you’re finished setting up your mixes and not use headphone mode while saving.

Base file name : THIS IS NOT JUST A FOLDER NAME but rather complete path and name used when saving to file. Program automaticly adds _001.wav, _002.wav, etc ... if not using metacharacters. You can use metacharacters to get intelligent naming : %a for artist name, %t for title, %f for original file name, %% for percent.
Example : basename c:/cdtodo/song will produce c:/cdtodo/song_001.wav, c:/cdtodo/song_002.wav while basename c:/cdtodo/(%a) - %t will produce c:/cdtodo/(artist) - song.wav

Save fast (but silently) : force saving to file to use the maximum possible speed. Sound will not play while saving.

Encode file into MP3 : force saved files to be MP3 files (not recommended). Requires the Blade encoder dll in the DJ Mix Pro folder.

Make one file per song : if not checked, sound is saved in one BIG file until sound stops. If checked, sound is saved to many wav files, each finishing in the middle of each mix.

toc

11.4   Misc options tab

Display options tab

Auto remove after play : remove song from playlist when done (incompatible with repeat mode).

Repeat mode : automaticaly play first song again after last song. This is the endless mode (incompatible with auto remove after play).

Work in secure mode : special mode designed to prevent b any mistake leading to sound stopping without mix. Shows a confirmation window for every dangerous action.

Show sound signal on songs dialog : toggles the signal displaying on songs windows.

Show spectrum analyzer on songs dialogs : toggles the spectrum analyzer displaying on songs windows.

Save playlist at exit : automaticaly saves the playlist on exit. Automatically load playlist on program launch (playlist is saved in autosave.m3v).

Save database at exit : automaticaly saves the database on close. Automatically load database on opening (database is saved in autosave.m3d).

Try to use ID3V2 tags : turn on the search for ID3V2 tags. (otherwise, only ID3V1 is searches and this is way faster!).

12   Song properties reference


Here is the most complex window of djmixpro. Do not be scared by the many fields in the window, as it will become clearer very soon.

toc

12.1   Mixing options tab

Mixing options tab


Note : the next two fields do not appear when properties of several songs are displayed at the same time.

Title : the song’s title if the file provides a mp3 title tag.

Length : the song’s length.

Note : the following fields appear even when properties of several songs are displayed. In such a case, if all songs have the same property value, the value is displayed. If songs have different property values, no value is displayed. Modifications apply only on properties that are set (not in indeterminate state).

Try Beatlock mix at end : this song is going to be analysed by the Beatlock routines. At the ending position, djmixpro will try to perform a Beatlock mix between this song and the next in the list.

Use normalization : at Beatlock analysis time, the song perceptive volume will be computed. The song volume will be adjusted at play time so that every song (having this property set) has perceptualy about the same volume.

Use fading auto detection results : this song is going to be analysed by a fading search routine. If fading in/out already occurs within the song, no fading in/out is performed by DJ Mix Pro. If not checked or if not starting at pos 0/stopping at end of song , the «Use fade in/out» are used to determine if djmixpro has to perform fade in/out rather than the »Use Fading auto detection results« .

Fade at begin : make song volume rise smoothly from 0 to about 100% when song starts. Note that when use fading detection is checked and song starts near position 0, this property is no used (auto detection results is used instead). A fade in is done if no fade in was detected in the song.

Fade at end : make song volume smoothly fall to 0% when song stops. Note that when «Use fading detection» is checked and song stops near the end, this property is no used (auto detection results is used instead). A fade out is done if no fade out was detected in the song.

Pitching done on both songs : if checked, both songs will change their pitch when mixing. If not checked, only the new one will. Changing pitch of both songs, you will be able to mix more songs togeither since the 2 songs allow about 16% pitch change instead of 8% with a single song.

Using volume (percent) : If set to something bigger than 0, target volume after fade in (default 100%) . If set to 0, then the normalized volume is used, or 100%. Is overridden if you touch the playing song’s volume control.

Fading in length : length of fade in ( time to rise from 0 to used volume)

Fading out length : length of fade out ( time to go down from used volume to 0)

Pitching length : length of pitch change for Beatlock mixes ( time to go from 100 to target pitch or from target pitch to 100%)

Start at : position within song where mix starts. This doesn’t apply for songs not started by a mix.

Stop at : position within song where mix stops. Can be a negative value if relative to the end of the song.

Mixing length : total length of mix. (length between beginning of next song’s fade in and end of current song’s fade out)

Beatlock status : the song’s Beatlock status. Is may be any one of the following statuses :NO STATUS (YET), BEEING BEATLOCKED,NOT USING BEATLOCK,STATUS OK, STATUS FAILED, BLK NOTALLOWED.

NO STATUS (YET) : this song has not been analysed yet by the Beatlock routines.

BEEING BEATLOCKED : this song is currently analysed by the Beatlock routines.

NOT USING BEATLOCK : this song doesn’t have the use Beatlock mix property.

STATUS OK : this song was successfully analysed by the Beatlock routines.

STATUS FAILED : the Beatlock routines failed to analyse this song.

BLK NOT ALLOWED : Beatlock analysis is currently down (you selected the Action->Stop Beatlocking menu).


Has silence in : (indicative) tells if song starts with a silence.

Has silence out : (indicative) tells if song ends with a silence.

Has fade in : (indicative) tells if song starts with a fade in.

Has fade out : (indicative) tells if song ends with a fade out.


Erase beatlock files : deletes the selected song(s) cache file(s), which contain beat position, BPM, and fading information. This is useful to recompute the cache file.

Divide BPM by 2 : You can use this to fix the BPM and beats if you feel automatic detection got a wrong BPM.

Shift by 1/2 beat : You can use this to fix the beats if you think automatic detection used the opposite beats (snares instead of drums for example).

Double BPM : You can use this to fix the BPM and beats if you feel automatic detection got a wrong BPM.
