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.
e offline player is a useful tool for preparing crates, audi-
tioning tracks, and setting cue and loop points.
Note: for more information about cue points and looping, see page 9.
For more information on crate organization, see page 14.

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.

Manual-9
left deck, and ctrl-k for the right deck. You can also jump to this
point without moving the fader by pressing Ifor the left deck,
and kfor 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.
Key Lock
When Key Lock is on, the key or pitch of the song stays locked at
what it would be if the track was playing at normal speed, regard-
less of the bend or pitch controls. Turn Key Lock on or off by
pressing the button to the top right of the Virtual Deck.
Tip: F5 and F10 will turn Key Lock on and off for the left and
right decks respectively.
Cue points
You can set up to ve 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.
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.
To remove a cue point, use the x button on the right side of
the cue point panel.
You can also control playback using the computer keyboard
— turn Caps Lock on to enable.

“A” on a French keyboard. Keep Caps Lock on when using these
shortcuts.
Censor
Use the censor button to ‘mask’ parts of a song, or use as a special
eect. 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

A cue point can occupy any of the 5 slots. You can drag and
drop cue points to change their order in the list. If you wish to
have the cue points sorted chronologically, check the sort cues
chronologically option in the setup screen. If you load the
same track on to both decks, you will be able to add or modify
cue points from either deck.
When you press a jump to cue point button while you are
not playing, it plays forward for as long as you hold down the cue
point button, and jumps back to the cue point when you release
the mouse button.
Tip: use the keyboard shortcuts ctrl-comma (for left) and ctrl-
dot (for right) to place cue points.
Looping
You can save up to 9 loops per track; these loops are saved in the
file, and will be present when you reload the track. To make a
loop, set the in-point by clicking the in button, and the out-point
by clicking the out button. To turn the loop on or off, click the
loop button. If you want the playhead to jump to the start of the
loop when you enable the loop, hold the control key and press
the loop button.
To adjust the in-point of the loop, click the in button. You
can use the arrow keys: to move the in-point towards the
start of the track, to move the in-point towards the end of the
track. Hold down the shift key while pressing the arrow key to
make coarse adjustments. Click the in button again to save the
in-point. e same applies to adjusting the out-point.
ere are 9 available loop slots per track. If a loop is set in
a given slot, the background (behind the loop number) will be
The stripe is a solid color near the marker point
The stripe grows a fth by each rotation closer to the marker point
green. Press the xbutton to clear the loop. If you click on the
number of a occupied loop slot, a red border will appear. is
indicates the loop is locked, and you will not be able to adjust the
end points or delete the loop until you unlock it, by clicking on
the number again.
Auto-looping
Auto looping allows you to create
loops that will automatically be in time with the music in tracks
that Scratch LIVE knows the BPM of. When you press an auto
loop button, a loop is created of the bar or beat value selected.
e loop is snapped to the beats in the song detected by Scratch
LIVE so even if when you press the button slightly out of time
Scratch LIVE will still create a perfect loop for you.
Five auto-loop buttons are available on screen at any one
time. ey range from  to 32 bars. e user can select the
autoloop range with the and buttons.
Auto-looping buttons require the track bpm to be set to work.
See Set auto BPM on page 6.
Pressing auto-loop for nbars will create a loop start point
from the nearest beat to the playhead (within reason), and set a
loop endpoint nbars in the future. Pressing auto-loop 1while
auto-loop 1is active will deactivate the loop. Pressing a different
auto-loop button while looping is active will extend the endpoint
of the current loop to the appropriate new auto-loop length.
You can also save an auto-loop to the next available slot.
When using an auto-loop, a save button is visible where the lock
loop button normally is.
The A - Slot
A special loop slot 'A' exits for auto-looping. e act of using the
auto-loop buttons sets a loop in the 'A' slot, following the rules
above. Turning a loop off using the auto-loop buttons returns
you to the loop slot that you were previously in at the time you
started auto-looping. Turning the loop o using the 'loop' but-
ton leaves you in the 'A' slot. e 'A' slot is not saved to disk
automatically—pressing 'save' saves the loop to the rst empty
slot in 1-9.
Auto-looping shortcut keys are alt-1 to 5 for the left deck,
and alt-6 to 9 for the right deck. ey correspond to the looping
buttons as laid out on screen: ie., if the onscreen buttons display
1 2 4 8 16 bar loops, alt-1 triggers 1 bar loop, and alt-5 triggers a
16 bar loop.
Autoplay
Click the auto button to enable autoplay.
With this setting turned on, when one track nishes playing, the
next track starts automatically. Load from a crate to play through
the songs in that crate, or from your library to play through your
library. Use the next | and previous | buttons to jump to
the next track or go to the previous track in the list. Play from
start must be checked in the setup screen.
Repeat
Use the repeat function to repeat the song.
Tip: Short “loop” samples can be turned into a continuous
track using repeat function. e loops need to be less than 10
seconds long, and cut at the start and end of a bar.

Manual-11
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.
Tempo matching display
Main waveform display
Track overview display
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.
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 dierent 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 10.

Manual-12
Kick Drum
Snare Drum
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.
Click on the waveform to ‘scrub’ or make ne 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 9.
Tip: Use the + and – keys to zoom in and out.
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
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 Use auto
gain on page 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
the final master gain control.

Tempo Matching display
In this example, the red part of the
wave represents a kick drum, while the
purple part represents a snare drum

Manual-13
MIDI Control
Overview
e MIDI Control feature in Scratch LIVE provides the ability to
map MIDI controls to Scratch LIVE controls, and thus control
the functions of Scratch LIVE using MIDI controllers such as
keyboards, triggers, sliders, and knobs.
Integrating MIDI controllers into your Scratch LIVE setup
can improve live performance usability, such as hitting pads on a
MIDI controller to trigger loops and cue points.
MIDI controller setup
e process of setting up a MIDI controller for use with Scratch
LIVE will vary depending on the hardware in question. Many de-
vices can connect to a computer using MIDI over USB, and will
either be supported directly by your operating system, or require
installation of drivers and configuration utility software. Follow
the manufacturers instructions for installation.
Other controllers may solely use a MIDI OUT connector to
send control messages, and will require a separate MIDI interface
unit to communicate to software. Generally the MIDI interface
will come with drivers and configuration tools which pass your
controllers output onto an available MIDI channel, which can be
used by Scratch LIVE.
Once your controller is installed and functioning correctly,
use the directions for assigning controls below.
Assigning Controls
To enable MIDI assign mode, click the MIDI button or
press ctrl+M.
Hovering the mouse pointer over a control will bring up the
MIDI assignment box, showing the current assignment status.
To assign a MIDI control, click on the control in Scratch
LIVE, then move the MIDI control. e MIDI assignment box
updates to show it has mapped the controls to one-another.
To un-assign a MIDI control, click on the control in Scratch
LIVE, and press return on your computer keyboard.
Note: Once in MIDI assign mode, Scratch LIVE controls will no
longer respond directly to the mouse—if you need to change a control
using the mouse, disable MIDI assign mode.
While in MIDI assign mode, controls which have MIDI
inputs assigned show a green box indicator around them.
MIDI platters
e Scratch LIVE virtual decks are not assignable to MIDI con-
trol. MIDI devices with platters on them all send dierent data so
user mapping is not possible. Support for specic MIDI devices
with platters on them will be introduced in Scratch LIVE 1.8.1.
Note: If you have a MIDI controller designed for DJing which
includes platter controls, assigning them to the Scratch LIVE decks
may be possible by installing a custom preset .xml file. Visit the
Scratch LIVE forums to discuss your controller with other users, and
for information regarding writing and trading user presets.
Assigning MIDI to other controls
Controls which aren’t normally visible are available for assign-
ment in the lower part of the screen when in MIDI assign mode.
ese include library navigation controls and the temporary cue
points for either deck.
Assigning Ctrl-Click Functionality
Some Scratch LIVE screen controls have additional functionality
assigned to ctrl-click. You can assign ctrl-click functionality to a
MIDI control, alongside the normal functionality.
For example, ctrl-click on the internal mode pitch slider
returns pitch to zero. To assign this to MIDI control, enter MIDI
assign mode, ctrl-click on the slider, and then assign one of the
pads to it. When you press the pad, the pitch goes to 0.
Presets
MIDI presets are accessible in the MIDI panel of the setup
screen. By default the current MIDI assignments in Scratch LIVE
are automatically remembered and loaded the next time you start
the program. e preset screen allows you to save and recall sev-
eral dierent MIDI setups. is is useful if you are using several
MIDI devices or want to quickly switch MIDI setups without
having to re-assign all your controls.
MIDI implementation
Scratch LIVE MIDI Control only supports:
• Note On/O
• Control Changes (standard 7-bit and 14-bit CC)
• RPN/NRPN (14-bit).

Manual-14
You can change the order of tracks within a crate by dragging
them up or down.
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 accident, you can
get it back from the recycle bin / trash. Crate files have the extension
.crate.
Subcrates
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:
• added
• album
• artist
• bitrate
• BPM
• comment
• composer
• lename
• genre
• grouping
• label
• length
• location
• remixer
• sampling rate
• size
• track
• video track
• year
Click on the column button to select which columns you
want to display.
To sort your library by a column, click the column header so
it highlights. For example, clicking on the album column header
will sort your library alphabetically by album title. To move a col-
umn, drag the header to the left or right. To resize a column, click
on the column boundary and drag it to the left or right.
Organizing your music
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 nd songs quickly and easily.
Grouping tracks into crates
Scratch LIVE supports several ways of organizing and sorting your
le 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 les into the following
crates, where any one track would be led in more than one crate:
• Vocal Jazz
• Cool Jazz
• Jazz Funk
• Modern Jazz
• Jazz Groove
• Fusion Jazz
To make a new crate, click the + button. To rename a crate,
double click the crate name.

Manual-15
Using the song browser
e song browser allows you to lter your song list by Genre, BPM, Artist and Album. To turn the song browser on or o, click the
browse button.
Searching
Scratch LIVE includes a search function to help you nd les quickly and easily. Enter text into the search box and Scratch LIVE will
automatically find as you type.
Tip: Use the keyboard shortcut ctrl-f to jump to the search box. is keyboard shortcut will also take you out of any crate or playlist that
you might be in and into your main library, so you can find any track in your collection. If you then click on a crate or playlist, the search
query will be cleared.
To select which elds the search function will look through, click on the left hand side of the search box. e drop down menu shows
which fields are currently being used.
Press esc or the x button on the right of the search box to clear the search.

• e track has been imported from the iTunes library,
and Scratch LIVE has detected some corruption in the
MP3 le. Solution: If possible, re-encode the MP3.
• e track cannot be found. Most likely the le has
been renamed or moved.
• Scratch LIVE is trying to import a track from the
iTunes library, but cannot find the file.
• Tracks that are read-only have a locked icon.
Display album art
MP3 les can contain album art information. To display this
album art, click the show album art button. ere are many
third-party applications available for adding album art to MP3s.
We recommend Apple’s iTunes™.
Prepare window
e prepare window is a holding area for tracks, much like
preparing a set by lifting records part way out of your record bag.
You can drag tracks from the main track list into the prepare win-
dow, or simply drag tracks onto the prepare button. ese tracks
will be removed from the prepare window once they have been
played. All tracks in the prepare window will be discarded when
you exit Scratch LIVE.
Tip: Use the keyboard shortcut ctrl-p to add tracks to the prepare
window.
Tip: Select the contents of the prepare window and drag them
onto the new crate button ( + ) to save the selection.
Review window
e review window shows the tracks you have recently played
in the order in which they were played. Tracks you have played
recently are colored green – press the clear button to reset the list
of recently played tracks.
Tip: Select the contents of the review window and drag them onto
the new crate button ( + ) to save a history of the tracks you played.
Editing ID3 tags
Much of the information associated with each file can be edited
from within Scratch LIVE. Double click on the attribute within
the main library to edit the attribute. Filename, length, size, bit
rate and sampling cannot be edited. is information is saved
in the file itself. Note that the protect library option in setup
must be unchecked to allow edits.
See Preparing your files on page 7 for details on prebuilding
overviews and the auto bpm feature.
Tip: Use the keyboard shortcut ctrl-e to edit text. Hold down
the ctrl key and move with the arrow keys to change to a different
field while staying in edit mode. When you have more than one file
selected, editing tags changes all the files in your selection.
Tip: e second column in the library �is the label color for that
file. Click it to bring up a color palette, and customize the virtual
deck for that file.
Tap Tempo
For tracks with no BPM information, there is a tap tempo button
displayed where the
BPM usually is, in
the song info area.
Pressing alt-space
bar activates the
tempo tapper (press
alt-space bar a second
time to activate the
tempo tapper on the right Virtual Deck). Tap the space bar along
with the beat.
After you’ve tapped the rst beat, you can switch to double
time tapping, half time, start of each bar etc. e range is set by
the first two taps, after that you can switch to any steady rhythm
you feel comfortable with – quarter notes, half note, whole notes.
Esc resets the BPM, Enter saves the BPM to the track. You can use
the mouse if you prefer.
Your CD player or turntable’s pitch slider doesn’t need to be at
zero, we do the math for you. You can also use the tempo tapper

Manual-17
Recording
e MP 4 allows you to record from several sources, allowing
you to convert vinyl and tape to digital, make samples, or record
a performance. e recording will be saved to disk as 24-bit
48K Stereo AIFF les. Recordings are saved in ‘My Documents\
My Music\ScratchLIVE\Recording’ on a PC, and ~/Music/Scratch-
LIVE/Recording/ on a Mac. Recordings will also be automatically
added to your Scratch LIVE library, and added to a crate named
Recorded.
By clicking immediately to the right of the record light, you
can select which input to record. e function mix will save the
mixed output to disk. You can choose whether the Mic Input is
included in this recording by pressing the MIC TO USB RECORD
button on the back of the MP 4. Functions a in and b in will
save Program A or Program B respectively. e mic function will
ignore all other inputs, saving only the microphone input.
Press the red record button to start and stop recording. Enter
a name for the recording in the text eld to the right of the
elapsed time. Press the save button bto save the recording to
disk.
Tip: Use keyboard shortcut ctrl-n to start a new recording.
Playing tracks direct from audio CD
You can play tracks direct from an audio CD in your CD-ROM
drive. When you insert the CD into your computer, it appears
under your Scratch LIVE library. Click on the CD and the tracks
will be displayed in the track list.
Tip: Disable any third-party CD Auto-Play functions be-
fore inserting a CD, as they may interfere with Scratch LIVE.
Previewing tracks
You can preview the tracks in your library using your computer’s
default media player if you don't wish to unplug your MP 4 to
use Scratch LIVE's oine player. Highlight a track and press ctrl-
o. is will launch the player your computer has associated with
the le type, and start playback. Also applies to the import panel.
See the built-in Oine player on page 7.
Autobackup
Scratch LIVE stores your library database and crates information
in a ScratchLIVE folder on your hard disk. is folder is created on
a drive when files from that drive are added to Scratch LIVE. is
way, there is one on your system drive and there will be one on
every external drive that you use with Scratch LIVE.
Auto backup creates a copy of the Scratch LIVE folder on
your system drive once a week on startup. If an external drive
containing a Scratch LIVE folder is detected it will be backed
up if the last backup on that drive is older than a week or if no
backup exists.
A copy of each ScratchLIVE folder called ScratchLIVEbackup is
created next to the folder it is backing up.
Auto-Backup will only keep one level backup at a time. Each
time autobackup runs it overwrites the previous backup.

Manual-18
Keyboard shortcuts ese actions can be accessed directly from the computer keyboard.
Key Action
