Inputs
MP 4 Overview
PROGRAM A and B INPUT switches select between the two
LINE and two USB Inputs. LINE 1 and LINE 2 are set for
PHONO level or LINE level using the associated push switch on the
rear panel.
PROGRAM A and B each feature LOW and HIGH tone and
LEVEL controls. Four-segment program level meters indicate
signals from –24 to +12. Clipping occurs at +22.
e balanced MIC input features a full-range LEVEL control
and is mixed with the Main-mix post-crossfader.
e MP 4 combines Rane mixer technology and Serato Scratch
LIVE software. e result is a mixer with the flexibility of playing
digital music directly from your computer while still supporting
traditional analog inputs. is two-bus mixer is able to simulta-
neously play stereo analog sources, play stereo digital files, and
digitally record Mic, Program A, Program B or Main-mix. You
can also operate the MP 4 as a stand-alone analog mixer without
a computer, or use it as a high-quality six-channel sound card
with Serato Scratch LIVE software, without analog sources.
e MP 4 is targeted at mobile DJ, night club, remix project
studio and post production applications. e Scratch LIVE MP 4
control screen includes many advanced features that enhance its
ability to mix and blend:
Outputs
Two stereo analog outputs are provided. e HOUSE output is
available on both balanced XLR and balanced ¼" TRS connec-
tors. e AUX output is available on balanced ¼" TRS connec-
tors and has an independent rear panel LEVEL control.
• Play / pause control, both forward and reverse
• Pitch ± and bend controls for fine tuning beat matching
• Fast forward and reverse
• Multiple cue points per track
Recording
One USB stereo output is available for recording. Scratch LIVE
software allows selecting Mic, Program A, Program B or Main-
mix as the source. (see page Manual-15). e MIC TO USB
RECORD switch located on the rear panel determines if the Mic
is included in the USB Main-mix record output. e ability to
record lets you archive your analog sources, record samples to use
in your performance or to record your performance.
• Censor (reverse a section without losing play position)
• Fader Start; Scrub track with mouse; Autoplay Crate…
and more.
e MP 4 is not a performance scratch mixer. It does not use
control vinyl or CDs and does not have a scratch fader.
While the MP 4 may be used as a generic sound card with
other software applications, for best performance and support we
highly recommend using Scratch LIVE. Performance using other
applications may vary and compatibility is not guaranteed.
e computer sees the MP 4 as three USB audio devices (two
stereo play and one stereo record). ASIO (for PC) and CoreAudio
(for Mac) drivers are included. e digital audio format is 24-bit,
3-byte PCM with a 48 kHz sample rate.
Cueing
Headphone Cueing allows independent selection of the Program
A or Program B input, making it possible to Cue any source
(digital or analog) with the push of a switch. e PAN PGM / CUE
control lets you Pan between the selected Cue input (pre-Cross-
fader) and the Main-mix (post-Crossfader).

MIC LEVEL control: Adjusts the Level of the MIC Input. e OL (overload) indicator lights when the maximum mic level has
been reached, 3 dB before clipping. If this lights up, either turn the MIC LEVEL down, or stop yelling.
2 Program INPUT selectors: Provide selection of LINE 1
,
LINE 2
,
USB 1 or USB 2 Inputs for each of the PROGRAM A or
PROGRAM B channels. LINE Inputs may each be set for PHONO or LINE level via the rear panel switch (see Rear Panel 6).
3 Program LOW and HIGH tone controls: adjust the equalization for each of the PROGRAM channels. Pointing these controls
straight up at their center detents takes the tone controls out of the signal path. is is not designed to be the only equalizer in the
system, this is intended to provide EQ between varying program materials. We recommend an external graphic equalizer for the
best system sound, connected between the HOUSE OUTPUTS and the amplifier.
4 Program LEVEL controls: set the volume of each PROGRAM INPUT, as you would expect! ese controls are pre-Crossfader, so
both Program Level controls also depend on the Crossfader setting (see 6).
5 Program meter: is four-segment meter shows signal presence (at -24), optimum signal level (at around 0), and a warning to
turn down the associated LEVEL control if the +12 indicator lights up.
6 Active Crossfader: Controls the mix of PROGRAM A and B LEVELS in a logical manner. When the Crossfader is all the
way left, only PROGRAM A is heard. When it's all the way right, only PROGRAM B is heard. When it's in the middle, both
PROGRAM A and
B
are mixed together equally. is is an Active Crossfader™ which uses a VCA to deliver an extended life with
reduced travel noise, but to insure trouble-free operation, see Fader Cleaning on page Manual-4.

activated and pressed in. Depressing a button sends Program signals to the CUE side of the PAN control. For example, when the
Crossfader is to the left (playing Program A to the House), listen to CUE B (Program B) on the headphones to audition, match
beats or prepare a starting point.

USB connection: Attach the included USB cable from here to the computer. e blue LED illuminates when the cable is con-
nected and receiving power. USB delivers two stereo inputs from the computer to the mixer (USB 1 and USB 2), and one stereo
record signal from the mixer to the computer.
HOUSE Output: e front panel HOUSE LEVEL control affects the volume at this Output. Connect either the XLR or ¼" TRS
(tip-ring-sleeve) jacks to a balanced equalizer or amplifier. Both Output types may be used simultaneously if needed. ough not
recommended, unbalanced ¼" TS (tip-sleeve) cables may be used for short runs (under 3 meters [10 feet]) to an amplifier with
unbalanced inputs. See the RaneNote “Sound System Interconnection” for wiring recommendations.

AUX Output: is delivers the same signal as the HOUSE Output, but has its own rear panel LEVEL control. is Output is not af-
fected by the front panel HOUSE LEVEL control. ese balanced ¼" TRS (tip-ring-sleeve) Outputs connect to a balanced equalizer
or amplifier (for a possible second listening zone) and follow the same interconnection rules as above.
5 MIC TO USB RECORD switch: In the YES position the Mic signal along with the Program mix is routed to the USB record output.
In the NO position only the Program mix is sent to the USB record output.

INPUTS 1 & 2: ese stereo Inputs are each switchable from a PHONO (RIAA) stage for magnetic cartridges (switch in) to a LINE
level Input suitable for any line level device such as a CD player (switch out). Each of these may be assigned to PROGRAM A or
B
using the front panel INPUT selectors. e PHONO GROUND screw connects those extra wires coming out of the turntables.
MIC Input jack: Accepts either a ¼" balanced (TRS) or unbalanced (TS) microphone plug, controlled by the front panel MIC
LEVEL control.
Fader Cleaning
With heavy use in harsh environments, the fader may need lu-
brication. is treatment extends longevity and can make a used
fader as good as new. e fader assembly must be removed from
the MP 4 for proper cleaning. We recommend any of the follow-

Windows Troubleshooting
If you have a USB PCI card, your computer may have allocated
bandwith to other devices, including your mouse, preventing
Scratch LIVE from recognising the MP 4. Unplug unneccesary
devices and install Scratch LIVE again. You may need to tempo-
rarily move your mouse to the built-in USB port. After installa-
tion, reconnect USB units as needed.
If other USB devices steal bandwidth, you may get a “inter-
face disconnected” message when launching Scratch LIVE, try
unplugging and re-plugging in the MP 4.
e ASIO Bit Depth and “Ask host to process during
callback” settings should not be adjusted unless you are having
problems.
Uncheck “Ask host to process during callback” if you have
audio dropouts. Your application may not support an ASIO
bitdepth of 32-bit. If this is the case, there will be no audio sent
to the MP 4.

Playing your first track
Preparing your files
Before launching the Scratch LIVE software, close all other pro-
grams on your Mac or PC.
When you first run Scratch LIVE, your library contains only
the pre-installed tracks. Load files into Scratch LIVE by pressing
the import button. Navigate the hard drive of your computer to
locate your audio files. Click on these files (or folders containing
files) and drag them onto the ✽ All
…
icon.
You can also import by dragging files and folders directly
from Windows Explorer (PC version) or Finder (Mac version)
into the Scratch LIVE library (see pic below).
Build overviews
Scratch LIVE supports importing M3U playlists.
If you run Scratch LIVE with the hardware interface discon-
nected, you will notice a button labeled build overviews on
the main screen. Click this to automatically build the overviews
for all the tracks in your library. e track name (and location)
are shown in the bar immediately below the button. Below this
are three more bars. e first bar shows track reading progress,
the second bar shows overview building, and the third bar shows
track writing progress. is process prepares the overviews of all
your tracks, and alerts you to any corrupt files you might have.
ese are indicated by Status Icons, shown on page Manual-16.
Loading tracks
Click on the ✽ All
…
icon to show all the tracks in your library.
To load a track on to one of the decks, drag the track from the
track list on to either deck. You can drag the same track on to
both decks.
Tip: Use the keyboard shortcut shift to load the high-
lighted track on to the left deck, and shift to load the high-
lighted track on to the right deck.
Supported file types
Set auto BPM
Scratch LIVE supports fixed and variable bit rate .MP3, Ogg
Vorbis, .AIFF, and .WAV file types. iTunes™ library and iTunes
playlists can be automatically imported in the setup screen by
clicking read iTunes library (see page Manual-17). You can
also play audio direct from CD. See Rescan ID3 tags on page
Manual-18.
If this option is checked, building overviews will include the
estimated tempos of your files. If Scratch LIVE is confident that
the auto BPM estimate for a file is accurate, it will be written to
an ID3 tag in the file. e auto BPM function will not be applied
if the track already contains BPM information. If you know your
files BPM will fall within a certain range, use the range dropdown
to avoid double or half value BPMs being calculated. Note: As
auto BPM is part of the overview building process, files in your library
with overviews already built will not be processed by clicking the
build overviews button. To rebuild overviews and use auto gain or
auto BPM on those files drag them onto the build overviews button.
Using tool tips
Click on the
?
icon to enable tool tips (right of the Scratch LIVE
logo). Tool tips provide a handy way to learn the various features
of Scratch LIVE. Move the mouse over a section of the screen to
bring up a context-sensitive tool tip.
Tool tips are available in several languages. Scratch LIVE will
display the tool tips in the language that your computer is set to.
If your language is not available, the tool tips will be displayed in
English.
Reset track gain
If you want to reset any track gain tags to 0 dB, drag them onto
this button to reset them to 0. To regenerate new values as you
build overviews, see Set auto gain on page Manual-19.
Tip: Holding the mouse over the
?
button with tool tips turned
on will show you a list of all keyboard shortcuts.
Virtual Deck
Virtual Deck shows everything about the speed and position
of a track. e circular progress bar around the edge is a visual
representation of the position within the song, and can be set to
flash to warn you that the track is nearing its end. e time and
remaining time are displayed in minutes and seconds. You can
also choose to display the
playback speed as a percent-
age pitch shift, or the pitched
BPM (BPM with pitch ad-
justment multiplier applied).
If the track has no BPM
information, percentage pitch
shift will be displayed.
Manual-7
e buttons above the cue points allow you to seed the base
playback speed – half speed, 33/45 or the speed of a 45 rpm
recording playing at 33 rpm, normal speed, 45/33 or the speed of
a 33 rpm recording playing at 45 rpm, or double speed.
You can also control playback using the computer keyboard
— turn Caps Lock on to enable.
Mixing with the MP 4
Scratch LIVE software has many features allowing you to smooth-
ly mix two tracks together. From left to right, these are:
Rewind – e rewind function speeds up the longer you press
the button.
Bend down – Create a temporary decrease in the playback
speed. Use bend down if the two tracks are in time, but this
track is slightly ahead of the other track.
Play / pause reverse – Press to play, press again to stop play-
back. You can adjust the brake speed knob in the setup
screen to range from an immediate stop to a slow turntable-
style ‘powerdown’. See page Manual-18.
Play / pause forward – Press to play, press again to stop play-
back. Uses the same brake speed as described above.
Bend up – Create a temporary increase in the playback speed.
Use bend up if the two tracks are in time, but this track is
slightly behind the other track.

Cue points
You can set up to five visual cue points within each track. Use the
+
button to place a cue point.
Click the arrow to the left of each cue point to jump to it.
You can also jump to cue points using keyboard shortcuts – 1
through 5 for the cue points on the left deck, and 6 through 0 for
the cue points on the right deck.
Notice that the stripe on the Virtual Deck jumps to the 12
o’clock position and changes color when you set a cue point –
you are at the cue point when the stripe is one solid color and at
the 12 o’clock position.
As the song plays on beyond the position of the cue point, the
colored bar will shorten by a fifth for each rotation. Likewise, as
you approach the cue point, the color will grow by a fifth each ro-
tation. For example, the picture below shows the song just before
the end of the 5th rotation before the cue point.
Left deck
qwertyuiop[
Right deck
asdfghjkl;'
Note: ese shortcuts are fixed to their position on the
keyboard, not the key letters, so that they are the same
regardless of keyboard language. For example, Play left deck
is “A” on a French keyboard. Keep Caps Lock on when using
these shortcuts.
Each cue point can have a different color. To change the color
of a cue point, click on the colored square and choose a new color
from the drop down menu.
Censor
Use the censor button to ‘mask’ parts of a song, or use as a
special effect. When you press the censor button, the track
starts playing backwards from that point. When you release
the censor button, the track plays forward from the point you
would have been, had you not pressed the censor button.
Fader start
Playback may be triggered from the Crossfader using the fader
start feature. To start playback using the Crossfader, pause the
track at the desired position and press the fader start button.
Now each time you move the Crossfader from its end position,
the track will start playing from that point. Moving the Cross-
fader from the right end point will start the left deck when
fader start is turned on, and moving the crossfader from the
left end point will start the right deck when fader start is on.
You can set the fader start point using the keyboard shortcut
ctrl-i for the left deck, and ctrl-k for the right deck. You can also
jump to this point without moving the fader by pressing I for
the left deck, and k for the right deck. e fader start point is
not saved with the file, and by default this point is set to the
start of the track.

Tempo matching display
Visual aids
When the track is playing several waveforms are displayed. Each
shows a different aspect of the track being played.
Track Overview display
is view provides a complete overview of the waveform of the
track, and includes a marker to show the current position within
the track.
is view is useful for finding transitions within the track.
e waveform is colored according to the spectrum of the sound
– red representing low frequency bass sounds, green represent-
ing mid frequency sounds and blue representing high frequency
treble sounds.
You can jump to different positions within the track by click-
ing on the Track Overview display.
Grey lines behind the overview show the length of the track
– a thin grey line every minute, and a thick grey line every 5
minutes.
e overview will be filled when you load the track onto a
Virtual Deck. You can also build the overviews for all your tracks
using the build overviews feature – see page Manual-18 for
details.
Note that the tempo display is aligned with the beginning of
the bar, so the peaks keep their relative position as the track plays.
is display does not show the relative timing of the beats, only
the tempos of the tracks. e peaks will still line up when the
tracks are playing at the same tempo, but are out of sync.
Track overview display
Tempo Matching display
e Tempo Matching display area provides a helpful tool for beat
matching. Scratch LIVE detects the beats within the track, and
places a row of orange peaks (for the track on the left side) above
a row of blue peaks (for the track on the right side) in the Tempo
Matching display area. When the two tracks are matched to the
same tempo, the peaks will line up.
Main waveform display
Manual-11
Main Waveform display
is view provides a close-up view of the track, including color-
coding to show the frequency of the sound; red representing low-
frequency bass sounds, green representing mid-frequency sounds
and blue representing high-frequency treble sounds.
You can also switch to a three-band spectrum view by holding
the crtl key and clicking on the waveform.
Kick Drum
In this example, the red part of the
wave represents a kick drum, while the
purple part represents a snare drum
Click on the waveform to ‘scrub’ or make fine adjustments to
your position within the track. e Main Waveform is zoomed
around the current position in the track.
See also: Cue points on page Manual-15.
Tip: Use the + and – keys to zoom in and out.
Snare Drum
Tempo Matching display
Beat Matching display
is view shows the position of beats within the track. When
beat matching, this view helps align the downbeats of the two
tracks. e markers are matched up when the two tracks are beat
matched.
Example
e following is a demonstration of using the visual aids to
help beat match. In this example, the track that is playing is on
the left deck, and the track to be mixed in is on the right deck.
1. Start the track playing on the right deck. After a few seconds,
blue peaks appear in the Tempo Matching display.
2. Adjust the pitch of the right deck until the blue peaks sit under
the orange peaks in the Tempo Matching display. Once they
are aligned, the two tracks have the same tempo.
3. Next align the markers in the Beat Matching display. Watch
the color of the items passing by in the Main Waveform dis-
play. Remember that a kick or bass drum will be red in color,
and a snare drum will be green or blue.
is technique will by no means guarantee perfect mixes, but
may help to speed up the process of beat matching.
Track gain
Beat matching display
Use the gain adjustment to balance the volume of the tracks in
your library. Any adjustment made to the gain of a track is saved
with the file, and will be reapplied to the entire track when it is
loaded again.
e level meter shows the level sent to the MP 4 after both
individual channel gain and master gain adjustment.
Note: for automatic gain setting of your tracks, see Set auto
gain and Reset track gain on page Manual-19.
Master gain
e master output of Scratch LIVE to the MP 4 can be controlled
using the master gain control. is adjusts the output volume of
all tracks played. e HOUSE LEVEL control on the MP 4 is

You can change the order of tracks within a crate by dragging
them up or down.
Organizing your music
Tip: e protect library option in the setup screen applies to
removing, editing and renaming crates. Check this option to
prevent changes to your crates. If you do delete a crate by ac-
cident, you can get it back from the recycle bin / trash. Crate
files have the extension .crate.
Scratch LIVE software can support an unlimited number of songs
– the only limitation is the size of the hard drive of your com-
puter. A number of features are included to help you to keep your
music organized and find songs quickly and easily.
Grouping tracks into crates
Subcrates
Scratch LIVE supports several ways of organizing and sorting your
file library. iTunes™ users will notice that Scratch LIVE automati-
cally incorporates your existing iTunes library and playlists.
Scratch LIVE uses digital “crates” for quick access to your
favorite collections. ere is no limit to the number of crates you
can create, and any given track can be placed in multiple crates.
For example, you could organize your files into the following
crates, where any one track would be filed in more than one crate:
You can drag and drop crates into other crates to make subcrates.
If you drag a crate to the very left of the crate panel, it will stay in
the top level of the crate structure. If you drag the crate a little to
the right, onto the name of another crate, it will make the crate
you are dragging a sub crate of the first crate.
Sorting your files
e track information display area can be customized to display
the columns listed below:
• Vocal Jazz
• Cool Jazz
• Jazz Funk
• Modern Jazz
• Jazz Groove
• Fusion Jazz
• Album
• Artist
• Bitrate

Additional setup
is section covers general preferences and adjustments you can make to improve the performance of the Scratch LIVE software. From
the top of the main screen, click on setup to get to this area.
Audio cache (seconds)
Play from start
Use the slider to set the amount of audio that is loaded into
memory. A small audio cache will place less load on your com-
puter, and the tracks will load faster. A large audio cache will give
you a bigger view of the waveform when the main waveform view
is zoomed out.
Enable this to start all tracks from the beginning. If this setting is
not enabled, freshly loaded tracks will continue to play from the
point the last track was at. is option is on by default.
Sort cues chronologically
e five cue points can be placed in any order, and can be
dragged up and down if you wish to reorder them. If you prefer
to lock them to chronological order, turn this option on.
Horizontal waveforms
Check this option to display the main waveform view horizon-
tally. e waveform will expand to fill available screen space. If
you are using a widescreen computer, increase the audio cache
size to make the waveform bigger.
Track end warning
Enable track end warning to flash the virtual deck as you ap-
proach the end of the track. e label will start flashing 20
seconds from the end of the record. e track end warning does
not apply to any tracks under 1 minute long.

Lock playing deck
Playback
Every DJs nightmare used to be lifting the needle of the wrong
turntable in the middle of a set. is setting helps to avoid the
digital equivalent; loading a new track to the wrong deck. When
this option is checked, you can only load a track if the target deck
is stopped.
Instant doubles
is allows you to quickly match the playhead position of two
tracks. With this option set, when you load a track on one virtual
deck that is already loaded on the other virtual deck (it must be
the same file), the playhead will jump to the position of the track
that was loaded first, with the keylock state and looping settings
copied. is setting overrides the play from start and play from
first cue point options.
Braking
is controls how fast the deck stops when play is stopped.
Counterclockwise, the stop is immediate. Clockwise rotation in-
creases the stop from a finger grab all the way to a slow turntable
power-down.
Play from first cue point
Enable this option to start all tracks from the first cue point. is
setting overrides the play from start option.
Audio output
By default the output of Scratch LIVE is stereo. You can also
select mono output. is setting is saved when you exit Scratch

Song Library
Protect library
Uncheck this setting to remove files and crates from your library.
Enable to lock your library and prevent accidental file or crate
deletion while using Scratch LIVE. Enabling this setting will also
lock all file tags and crate names, so that no text can be changed.
Set auto gain
For songs with overviews built (by version 1.7.2 or later), check
this if you want to use the calculated auto gain value while play-
ing songs. ere is also a target gain dropdown menu next to
this option, that sets the target gain that you would like. is
can be turned on / off, and the target gain changed on the fly. If
you change the target gain while a song is loaded to a deck, the
change will apply the next time a song is loaded.
When a track is in auto gain mode (auto gain is turned on
and the track has an auto gain setting), the track gain knob ap-
pears depressed to provide visual feedback that auto gain is in
effect for that track. To fine tune your gain values, you can still
change each file by the gain knob. To reset the gain to the cal-
culated auto gain value, Alt-Click the gain knob. To remove the
auto gain value, see Reset auto gain on page Manual-7.
Show all file types
Enable this option to show all files when importing tracks into
Scratch LIVE. If this option is not selected, only files that Scratch
LIVE can play will be displayed.
Include subcrate tracks
As described on page Manual-14, you can drag crates into other
crates to make subcrates. If you have the “include subcrate tracks”
option turned on, any crate will also display the contents of all its
subcrates.
Read iTunes™ library
Existing iTunes users will recognize many features from iTunes.
Scratch LIVE can read the iTunes library format, and will auto-
matically import the iTunes library and iTunes playlists. iTunes
is available for Mac and PC, for more information about iTunes,
Note: it may take some time to read your iTunes library if
it contains a lot of tracks. If you edit the file information of
tracks from your iTunes library, the changes will not appear in
iTunes until after you play the track. Scratch LIVE cannot play
files that have been protected by Digital Rights Management
systems, such as those sold through the Apple iTunes Music
Store.
Auto fill overviews
Enable this setting to automatically generate the track overview
as soon as a track is loaded. If this setting is not enabled, the
track overview will be generated as the track plays. Automatically
generating the track overview uses more of the computer’s CPU
power, and should be disabled on slower computers.
Center on selected song
With this option on, scrolling up and down in your library holds
the selected track in the middle of the library panel.
Hi-fi resampler
is significantly reduces digital distortion at very slow or very
fast record speeds, increasing the CPU load slightly. is option is
on by default, and the old resampler is used when switched off.
Rescan ID3 tags
Click this button to force Scratch LIVE to re-read all file tags. Use
this function if you have edited or modified file tags outside of
Scratch LIVE.
Tip: Rescanning the tags is a handy way to identify all
the files that Scratch LIVE can’t find (for example if the files
have been altered or moved). ese tracks will show up red in
the main track list, with an exclamation mark in the status
column. You can sort by the status column to group all these
tracks together.
