MP 4 Overview
e MP 4 combines Rane mixer technology and Serato Scratch
LIVE software. e result is a mixer with the exibility 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:
• Play / pause control, both forward and reverse
• Pitch ± and bend controls for ne tuning beat matching
• Fast forward and reverse
• Multiple cue points per track
• 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.
Inputs
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.
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.
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. 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.
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).

Manual-3
Front Panel Description
1 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.
2Program 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).
3Program 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.
4Program 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).
5Program 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.
6Active 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 4.
7 HOUSE LEVEL control: Adjusts the Output Level of the Main-mix to the HOUSE Outputs.
8 CUE switches: Select Program A or B in any combination to the PHONES . e associated yellow indicator lights when a CUE is
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.
9 PAN control: Changes the relative levels of the Cue and Program mixed together in stereo to the PHONES . Adjust this control
anywhere between Program and Cue:
PGM follows the Main-mix (House) Output.
CUE is determined by the CUE switches and only goes to the headphones.
0 PHONES LEVEL and headphone jack: As you guessed, plug your headphones in here and adjust the overall volume with the
LEVEL control. CUE 8 and PAN 9 select the source.
q POWER indicator: Illuminates to let you know the MP 4 is plugged in and ready to go.

Rear Panel Description
1Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. is mates with an IEC 60320 C5 line cord (USA
domestic). Do not lift the ground connection!
2 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.
3 HOUSE Output: e front panel HOUSE LEVEL control aects the volume at this Output. Connect either the XLR or ¼" TRS
(tip-ring-sleeve) jacks to a balanced equalizer or amplier. 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 amplier with
unbalanced inputs. See the RaneNote “Sound System Interconnection” for wiring recommendations.
4 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 amplier (for a possible second listening zone) and follow the same interconnection rules as above.
5MIC 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.
6 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.
7 MIC Input jack: Accepts either a ¼" balanced (TRS) or unbalanced (TS) microphone plug, controlled by the front panel MIC
LEVEL control.

Manual-5
Getting started on Mac OS X
Before you install the Scratch LIVE software, check for free
software updates at scratchlive.net. e software version that came
with your MP 4 is printed on the installation CD. e Scratch
LIVE software is updated frequently, all updates are free, and
available at scratchlive.net.
To install the software, double-click on the installer icon
from the CD-ROM, or the installer you just downloaded from
scratchlive.net.
When you connect your MP 4 to your Mac, it will appear to
the Mac operating system as multiple sound outputs and inputs.
Go to the audio section of the system preferences panel to select
the desired settings.
On the output tab, choose MP 4 USB1 Out or MP 4 USB2 Out,
and on the MP 4 select the same USB 1 or 2 INPUT.
On the input tab, you will see four MP 4 devices listed.
ey are, in order:
1. e Main-mix output
2. Program A
3. Program B
4. Microphone
e MP 4 can be used with third party software, as well as the
Scratch LIVE software included with it. On the Mac, you can use
the MP 4 with any audio application, though technical support is
limited to Scratch LIVE.
Getting started on Windows
Windows XP
1. Disconnect any unneccessary USB devices from your PC.
2. Connect the MP 4 to your computer with the supplied USB
cable.
3. e Found New Hardware bubbles appear:
MP 4
USB Composite Device
MP 4 USB1 Out
USB Audio Device
MP 4 USB2 Out
USB Audio Device
MP 4 Line In
USB Audio Device
MP 4
USB Human Interface Device
Your new hardware is installed and ready to use.
4. Before you install the Scratch LIVE software, check for free
software updates at scratchlive.net. e software version that
came with your MP 4 is printed on the installation CD. e
Scratch LIVE software is updated frequently, and all updates
are free. To install the software, double-click on the installer
icon from the CD-ROM, or the installer you just downloaded
from scratchlive.net. Follow the on-screen instructions.
5. Click “Next” to continue the install, or choose custom if you

ASIO driver.
6. Windows may complain that the software driver is not digitally
signed. Defy Microsoft and choose Continue Anyway.

Manual-6
7. Click Finish once installation is complete. Scratch Live appears
in the Start Menu under All Programs > Serato > Scratch Live.
Windows XP treats each USB port individually. You might like to
install Scratch LIVE on all of your USB ports, so you can connect
the hardware to any port.
As soon as you install the device driver, the operating system
does not see the MP 4. at means you can either [A] not install
anything, and windows will see the MP 4, or [B] install Scratch
LIVE and the ASIO driver, and then you can use the MP 4 with
Scratch LIVE or an ASIO application only.
Windows Vista
When you plug in your hardware:
1. A Found New Hardware wizard will pop up.
2. Choose "Locate and install driver software"
3. After Windows looks for the driver it will say "Windows
couldn't nd driver software for your device. Choose "Browse
my computer for driver software"
4. Browse to the location that you extracted the ScratchLIVE .zip
le to. Choose the Drivers folder.
5. Click next and Windows will say "Windows can't verify the
publisher of this driver software". Click "Install this driver
software anyway".
6. When you see the bubble "Your new hardware is installed and
ready to use," proceed to install the Scratch LIVE driver.
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.
Third-Party Software
e MP 4 can be used with third party software, as well as the
Scratch LIVE software that comes with it. When you install
Scratch LIVE, an ASIO driver will also be installed. You can use
the MP 4 as a sound card for any third party software that sup-
ports the ASIO standard. Go to the audio interface control panel
in the third party software, and choose the MP 4 Driver. Launch
Control Panel to access more settings for the MP 4 ASIO driver.
You can reduce the USB Buer Size for lower latency.

Manual-7

grams on your Mac or PC.
When you rst 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 les. Click on these les (or folders containing
les) and drag them onto the ✽ All … icon.
You can also import by dragging les and folders directly
from Windows Explorer (PC version) or Finder (Mac version)
into the Scratch LIVE library (see pic below).
Scratch LIVE supports importing M3U playlists.
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
Scratch LIVE supports xed and variable bit rate .MP3, Ogg Vor-
bis, .AIFF, .AAC, and .WAV le types. iTunes™ library and iTunes
playlists can be automatically imported in the setup screen by
clicking read iTunes library (see page 20). You can also play
audio direct from CD. See Rescan ID3 tags on page 20.
NOTE: iTunes Music Store DRM-protected files are not able to
be played back using 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.
Tip: Holding the mouse over the ? button with tool tips turned
on will show you a list of all keyboard shortcuts.
Preparing your files
Build overviews
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 16.
Set auto BPM
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 le. 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.
Offline Player
e offline player is available when Scratch LIVE hardware is not
connected, and outputs through the current default audio device.
Load a track to the offline player by dragging and dropping onto
the deck, or pressing shift . If the end of the loaded track is
reached, the next track in the current playlist is played automati-
cally.

Virtual Deck
Virtual Deck shows everything about the speed and position of
a track. e circular progress bar around the edge is a visual repre-
sentation of the position within the song, and can be set to ash
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.

Playback and Speed Controls
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 braking in the setup screen to range
from an immediate stop to a slow turntable-style ‘powerdown’.
See page 19.
Play / pause forward – Press to play, press again to stop play-
back. Uses the same braking 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.
Fast forward – e fast forward function speeds up the longer
you hold the button.
e Scratch LIVE software has two pitch sliders – a large slider
for coarse pitch adjustment, and next to it, a small pitch slider for
ne adjustments. Click above or below the handle on the large
pitch slider to make small pitch adjustments, or hold the shift
key and drag the pitch slider to move it slowly. Drag the center of
the small pitch slider to make fine pitch adjustments, or click on
either side of the small slider to pitch bend.
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.
