5. USING DJ CONTROL MP3 E2 AT A PARTY
5.1. Overview
You are now about to learn everything a DJ needs to know to host his or her first parties. Let’s
start at the beginning, namely setting up the party: no DJ would allow himself to arrive
unprepared, which is why he would have organized his material and selected his records
beforehand.
You should do the same by sorting through your music. Have a good look through your collection
of CDs as well as your MP3 and WMA files and select the songs you are going to use. In order to
be able to mix tracks effectively, you must know the tracks perfectly.
Once this is done, make sure that you have all the hardware you will need. Got your computer,
DJ Control MP3 e2, a pair of speakers –and some headphones, if you have a multi-channel
sound card –handy? Perfect, then you’re ready to go!
You’re probably asking yourself: and now, how do I get started? By way of introduction, here are
the basic principles of DJing: a DJ works with two decks (or turntables). The first deck plays one
track, while the DJ uses the second deck to get the next track ready. He can then work on this
second track (speed it up so that it is at the same tempo as the track that is currently playing, etc.)
before playing it out loud. Towards the end of a track, the DJ starts playing the track on the other
deck and does a mix, which is to say a blending of the two tracks to create a perfect transition.
The two decks share a single music list. You can load your tracks from the explorer window.
- Move the mouse pointer onto the MUSIC icon in the middle part of the screen.
The explorer window opens with the music list in the lower right-hand part of the screen.
Please read through the following sections to learn more about the art of DJing. We also
recommend that you consult the help documentation of the software supplied with your DJ
Control MP3 e2 for additional information.

14/34–User Manual
5.3. Monitoring with headphones
To prepare his musical line-up, a DJ uses headphone monitoring: he listens to a track on his
headphones while the other one is being played over the speakers, allowing him to adjust the
tempo so that the tracks flow seamlessly together. He can also add audio effects, set cue points
(markers) to start up at a specific point in a track, create rhythmic loops, adjust Treble, Medium
and Bass frequencies, and so on. Your DJ Control MP3 e2 allows you to carry out this kind of
headphone monitoring, depending on the hardware and software you have at your disposal.
If you only have a stereo sound card, you cannot carry out headphone monitoring.
Please note that both Mac desktop and laptop computers, as well as most PC laptops, feature
1 stereo output ONLY; so if you have such a computer and want to use the headphone
monitoring feature, you must have an external multi-channel sound card.
If you have a sound card with an output of 4 or more channels (such as the Hercules Muse
Pocket LT sound card, or a similar sound card and), however, you can monitor music on
outputs 3 and 4 over your headphones.
In order to use the headphone monitoring mode on your multi-channel sound card:
a) Verify that the speaker configuration is set to either 4 or 5.1 channels. This should
ideally be done using your sound card's configuration program.
Your operating system also offers certain configuration possibilities:
PC: Start > Control Panel
- Sound and audio devices (Windows XP)
- Sound (Windows Vista / 7)
Mac: Application > Utilities > Audio MIDI Setup
b) Make the necessary connections to your sound card as follows:
- Connect your speakers to the FRONT connector (usually green).
- Connect your headphones to the BACK/REAR connector (usually black).

User Manual –15/34
Please note that connector labels on certain sound cards may vary. Consult your sound
card’s documentation for specific details.
c) When running VirtualDJ for the first time, you will need to configure the software for
use with your sound card.
- Click the Config button.
- In the Sound Setup tab, configure as follows:
Input : None
Output(s): Headphone
The adjacent menu should then display the default configuration: Master : Front output /
Headphones : Rear output.
Sound card: 4.1 card (PC) / 4 Out Card (Mac)
Select the sound card you want VirtualDJ to use in the the adjacent menu.
You will need low impedance headphones for monitoring (less than 32 Ohms), as the sound level
will be too low if you use high impedance headphones. To monitor a deck, press the monitoring
button for the corresponding deck. Make sure to disable any 3D positioning features on your
sound card, or else you may end up hearing echoes of the track you are monitoring in your main
mix!
When a track on deck A is being played in the room, you should use your headphones to monitor
the track on deck B, and when a track on deck B is being played in the room, you should press
the headphone monitoring button on deck A to prepare the next track, and so on. When a
monitoring button is lit up on your DJ Control MP3 e2, it indicates that the deck in question is
being monitored.
In VirtualDJ, the boxes in the upper middle part of the screen representing decks 1 and 2 reflect
your monitoring status: in the case below, deck A (the left-hand deck, or deck 1 in VirtualDJ) is
green, indicating that it is being monitored on your headphones, while deck B (the right-hand
deck, or deck 2 in Virtual DJ) is red, indicating that it is not being monitored.

16/34–User Manual
5.4. Speeding up or slowing down a track
The main reason for speeding up or slowing down a track you are about to play is to match its
BPM (i.e. the number of beats per minute) and synchronize its beat with that of the track already
playing. In this way you can mix the two tracks together smoothly when switching from one deck
to another. There are two ways to regulate the speed of a track: by manually adjusting its pitch,
and automatically via beat-matching.
On vinyl decks, the pitch allows you to adjust the rotation speed of the turntable. This adjustment
therefore changes the speed of a track by modifying its overall tonality (for example, a track that
has been sped up significantly will sound much more high-pitched, or sharper).
You can therefore use one of the DJ Control MP3 e2’s Pitch knobs to modify the pitch of a track.
VirtualDJ also offers a very useful function to automatically match the BPM of tracks that are
playing and synchronize their beats for easy mixing: this function is called beat-matching. Press
the Sync button on either deck to toggle beat-matching on and off for the deck in question. When
the Sync button stays lit up in blue, beat-matching is enabled on that deck; when the LED is off,
beat-matching is disabled on that deck.
When a track is being played on a deck, the BPM is displayed just above the track’s timeline, to the right (the
percentage next to the BPM indicates how much faster (+x.x%) or slower (-x.x%) the current BPM is in relation
to the track’s normal BPM):
- Press the Sync button on a deck to automatically match the BPM and synchronize the beat of the track on
that deck with that of the track playing on the other deck.
The Sync button lights up. This track’s BPM is automatically matched to that of the track being played on the
other deck and their beats are synchronized.
- Make a transition from one track to the other (please see section 5.7. Switching from one track to another).
If you decide to switch off beat-matching on this deck, press the Sync button again. The Sync button goes
dim, indicating that beat-matching is now switched off.
5.5. Creating cue points
Finished synchronizing the tempos of your tracks? Great –but depending on the tracks you are
using, you may wish to start up playback at a specific point and not simply at the beginning.
This is possible by inserting cue points into your tracks. A cue point allows you to locate the start
of an interesting rhythmic section and launch playback of a track at that section. VirtualDJ allows
you to set 1 cue point per track using your DJ Control MP3 e2

ITALIANO
DEUTSCH
ESPAÑOL
NEDERLANDS
ENGLISH
FRANÇAIS
User Manual –17/34
To set a cue point:
- When you get to the rhythmic section you are looking for, press Play/Pause.
- Press CUE to set this position as cue point 1.
A marker is inserted in the track’s timeline.
To go to a cue point when playing a track for the audience:
- Press Play/Pause to launch playback of the track from the cue point you have set.
5.6. Creating loops
Using the same marker principle, you can also create loops, which are sections of a track
repeated to infinity.
Loops are controlled using the 1, 2, 3and 4buttons in the Loops/Fx section of your DJ Control MP3 e2 which
generate loops based on 1, 2, 4 and 8 measures, respectively. Therefore, button 1generates a short loop,
while button 4generates a longer loop.
- Make sure that the Shift button in your DJ Control MP3 e2's Loops/Fx section is not lit up (if it is lit up, press
the Shift button to turn it off).
- During playback of the track, when you get to a rhythmic section where you want to create a loop, press
button 1, 2, 3or 4(depending on how long you want the loop to be).
The rhythmic section is repeated to infinity.
- Press button 1, 2, 3or 4again to resume normal playback of the track.
5.7. Switching from one track to another
The art of mixing consists of preparing the next track while a given track is being played. When
the track being played reaches its end, the DJ switches from one track to the other progressively
using the cross fader, which regulates the volume of the two decks. This technique enables you
to avoid empty space between two tracks.
Your DJ Control MP3 e2 allows you to work with digital audio files stored on your computer. This
section will give you some practical examples of how you can switch from one musical track to
another using the VirtualDJ software if you are using headphone monitoring.
Example: An MP3 file is being played on deck A (the left-hand deck). You can change the EQ of
the track using the Treble, Medium and Bass knobs, so these knobs on deck A have been
adjusted for the perfect sound mix with the track that is playing. The cross fader is pushed
completely to the left, so only what is being played on deck A will be heard by the audience.

18/34–User Manual
While the track on deck A is playing for the audience, press the headphone monitoring button on
deck B (the right-hand deck) so that you can hear the track you will be preparing on deck B on
your headphones while the audience continues to listen to the track being played on deck A over
the speakers in the room (assuming you have a multi-channel sound card that has been
configured for use with headphones in VirtualDJ, as described in chapter 5.3 Monitoring with
headphones). The headphone monitoring button on deck B lights up, indicating that deck B is
being monitored on your headphones.
- Step 1: While the track on deck A is playing, mute the EQ controls (Treble, Medium and Bass
knobs) on deck B.
- Step 2: As the track on deck A is nearing its end, start up playback on deck B and start moving
the cross fader towards the center.
- Step 3: While the tracks on both decks are playing, restore the EQ controls (Treble, Medium
and Bass knobs) on deck B.
- Step 4: Mute the EQ controls (Treble, Medium and Bass knobs) on deck A.
- Step 5: Move the cross fader all the way to the right, to deck B.
- Step 6: Restore the EQ controls (Treble, Medium and Bass knobs) on deck A, so that you
can prepare the next track to be played on deck A on your headphones; and so on.
The following diagrams give you an idea of how the Treble, Medium and Bass knobs and cross
fader are adjusted for the procedure described above.
Step 1: Mute the EQ controls
(Treble, Medium and Bass
knobs) on deck B.
Step 2: Move the cross fader
to the center.
Step 3: Restore the EQ
controls (Treble, Medium and
Bass knobs) on deck B.

Step 4: Mute the EQ controls
(Treble, Medium and Bass
knobs) on deck A.
Step 5: Move the cross fader
all the way to deck B.
Step 6: Restore the EQ
controls (Treble, Medium and
Bass knobs) on deck A.
Should you notice a slight discrepancy in the tempos of the two tracks, use the Pitch bend - / +
buttons. These buttons slow down or speed up playback; playback returns to the normal speed
when the button is released.
Simply repeat this procedure when you are getting ready to play your next track on deck A again.
In no time at all, you’ll be mixing like a pro!
The VirtualDJ software also features an automatic mixing function, which ensures the
adjustment of BPM between tracks and the switch from one deck to the other. This allows you
to take a well-deserved break during your mix without having to cut off the music and spoil the
mood in the room!.
- Move the mouse pointer onto the PLAYLIST icon in the lower right-hand part of the screen.
The playlist appears.
- Click in the playlist window.
The automatic mixing function is enabled, and tracks will link up one after the other. To return to manual
mixing, click again.

20/34–User Manual
5.8. Adding effects to a track
If you want to call attention to a new track during your mix or prepare your audience for a
microphone address, you can add effects to tracks you are playing.
- Make sure that the Shift button in your DJ Control MP3 e2's Loops/Fx section is lit up (if it is not lit up, press
the Shift button to turn it on).
- Press button 1, 2, 3or 4 to add the corresponding effects in VirtualDJ.
Note: in VirtualDJ, other effects can be set for buttons 1, 2, 3and 4by clicking .
5.9. Scratching
DJ Control MP3 e2 allows you to scratch your MP3s and CDs in the same way that a DJ
scratches vinyl records. To do this you will use the DJ Control MP3 e2’s jog wheels, together with
the cross fader to boost/interrupt the sound.
For the best results when using your DJ Control MP3 e2, try to position your hands as shown
below:
There are many scratch effects, the most well-known of which are described below:
Baby Scratch
No need to use the volume control for this basic scratch. It consists of doing a forward scratch,
immediately followed by a backward scratch.
Tear Scratch
The Tear Scratch doesn’t use the volume control either. As with the Baby Scratch, you do a
forward scratch followed by a backward scratch, but this backward scratch is broken down into
two different speeds: you must first scratch quickly, and then slowly. Thus, the different steps are
as follows: forward scratch, quick backward scratch, slow backward scratch.
