WEAR PARTS: This product contains the following wear part subject to the ninety (90) day warranty period described on page Warranty-1:  
(1) Active Crossfader #11646.  
Manual-1  
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.

HOUSE LEVEL control: Adjusts the Output Level of the Main-mix to the HOUSE Outputs.  
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.

q
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.  
POWER indicator: Illuminates to let you know the MP 4 is plugged in and ready to go.

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.  
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 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-  
ing cleaning solutions:  
CLEANING INSTRUCTIONS  
A. Fader assembly replacement (part #11646)  
1. Unplug the MP 4.  
2. Remove the bottom cover.  
3. Remove the fader screws from the front panel.  
4. Draw fader assembly out through the bottom.  
5. Remove ribbon cable from old fader.  
6. Attach ribbon cable to new fader, screw onto front panel and  
replace bottom cover.

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.  
Manual-6  
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.  
Fast forward – e fast forward function speeds up the longer  
you hold the button.

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.  
The stripe grows a fifth by each rotation closer to the marker point  
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,  
regardless 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.

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 first 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  
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.

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 when no song is loaded, for finding the BPM of regular  
records, for example.  
Looping  
You can save up to 9 loops per track; these  
loops are saved in the file, and will be pres-  
ent 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  
green. Press the x button 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.  
Autoplay  
Click the auto button to enable autoplay.  
With this setting turned on, when one track finishes 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

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-10  
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  
the final master gain control.  
Manual-12  
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

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.

Searching  
Scratch LIVE includes a search function to help you find files 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 fields 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.

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 Manual-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.  
Tracks that are read-only have a locked icon.  
Display album art  
MP3 files 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™.  
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.

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.  
Maximum screen updates (per second)  
is feature allows you to throttle back the screen refresh rate.  
Users with slower computers might like to do this if they are hav-  
ing performance issues. It could also be useful if you want to limit Playback keys use shift  
Scratch LIVE’s processor usage, for example if you are running a  
recording program at the same time. e default setting is 60 Hz,  
or refreshed 60 times per second. is setting applies to the entire applies to all cue points (1...0) and cue controls (QWERTY etc).  
screen (i.e. the Virtual Decks, the Waveforms, the library, and the  
setup screen).  
is is checked by default. Unchecking this option will enable all  
of these keys without pressing shift or having caps lock on. is  
See page Manual-12.  
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  
LIVE.  
Manual-18  
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 ne 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,  
visit www.apple.com. Click read iTunes library to activate.  
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.

Troubleshooting and FAQ  
MP 4 Block Diagrams  
The Scratch LIVE software does not recognize the MP 4  
It takes five seconds for the software to detect the MP 4. e  
MP 4 can be unplugged at any time; you do not need to exit  
Scratch LIVE before disconnecting the MP 4. Use the supplied  
USB cable, longer lengths are not recommended.  
On some Windows machines each USB port is treated  
separately, so you will need to install the driver separately for each  
USB port.  
CUE A  
The first time I play a new track, it takes a while to load  
Scratch LIVE has to read the entire file and create a file index  
the first time it is loaded. is may take a few seconds for longer  
files. After the first load, it should load instantly. See Build over-  
views on page Manual-18.

I have a particular MP3 that won’t play / plays badly / takes a  
long time to load / crashes the program. What should I do?  
e file may be damaged. Please go to the forum at scratch-  
live.net and notify the support team that you have a bad file. By

Your database and crates are stored in the folder Home\Mu-  
sic\ScratchLIVE on a Mac, and My Documents\My Music\Scratch-  
LIVE on a PC. Crates have the file extension .slc. If your library  
contains tracks that are stored on a drive other than your boot  
drive, a hidden folder called .scratchLIVE will be created in the  
root of that drive, and a separate database will be made in this  
folder. If it is a removable drive, the tracks will only appear in  
your library when the drive is connected.

Why do none of the songs I have imported from iTunes show  
up in Scratch LIVE?  
USB 2R  
iTunes’ default encoder is set to AAC, which Scratch LIVE  
currently does not support. You need to re-encode those files to a  
supported file type (AIFF, WAV, OGG, MP3).  
To change the default encoding preferences in iTunes, go to  
Preferences > Importing. Change the “import using” option to a  
supported file type and click OK.  
To re-encode a track, select/highlight it. Go to Advanced >  
Convert Selection to.... You can lose quality after you re-encode a  
track, so it's best to start from the original source if possible.

Corrupt file descriptions and diagnoses  
is MP3 contains frames which do not conform strictly to the official MP3 specifica-  
tion. Scratch LIVE can not be certain that this file will play back 100% accurately.  
Corrupt file: This MP3 contains invalid  
frames.  
is file contains two or more contiguous corrupt frames. Since corrupt frames are  
replaced with silence, this could result in what might sound like an audio glitch.  
Corrupt file: This file contains corrupt  
frames that may result in audible  
glitches.  
e first MPEG audio frame in this file refers to audio that should be present before it  
but is not. is is usually the result of incorrect MP3 editing. Since a corrupt frame is  
replaced with silence and most songs start with silence, the resulting silence might not  
be noticeable. All the same, listen to the beginning of the song, just to be sure.  
Corrupt file: This file has been split. You  
should check the beginning for audio  
glitches.  
Decoding of an MPEG audio frame failed. is means that the frame contained  
invalid data. As usual with corrupt frames, this frame will be played as silence.  
Corrupt file: This MP3 contains frames  
with corrupt data.  
is is a rare message and you should not see this. Do notify us if you see it and please  
send us the file that caused the message to appear so we can fix the problem.  
Corrupt file: This MP3 lost syncronization  
between the frame index and the frames.  
Self explanatory. Possible causes are disk bad sectors, file system corruption, wrong file  
types, wrong file extensions, etc  
Corrupt file: This MP3 is completely  
invalid and is not playable.  
Scratch LIVE encountered a lot of invalid data while looking for audio in this file. is  
message alerts you to the fact that the file you're trying to play contains corrupt data.  
is may, or may not, affect playback.  
Corrupt file: This file contains invalid  
audio data.  
No audio could be found in this file, which means it is completely unplayable as far as  
Scratch LIVE is concerned. Please make sure this really is an audio file.  
Corrupt file: This MP3 contains no valid  
frames.  
While scanning this file, Scratch LIVE found frames belonging to multiple MPEG  
layers. Scratch LIVE does not support MP3s that contain frames from multiple layers  
– some frames may be output as silence.  
Unsupported file: This MP3 contains  
multiple layers.  
Self explanatory. At the moment, Scratch LIVE does not support files that are 2GB in  
size (or larger).  
Unsupported file : This file is more than  
2GB in size.  
is file contains chunks of data that are larger than 2GB. Scratch LIVE does not sup-  
port files that are more than 2GB in size.  
Unsupported file : This file has data  
blocks greater than 2GB in size.  
is WAV file contains no recognizable WAV data. It is quite possible that this might  
not be a WAV file.  
Corrupt file: This WAV contains no valid  
chunks.  
WAV files can contain data in several formats. Scratch LIVE only supports WAV files  
that contain data in the PCM format.  
Unsupported file: This file's data is not in  
PCM format.  
Scratch LIVE does not support sampling rates greater than 44.1kHz. If you see this  
Unsupported file: This file has a sampling  
rate greater than 48kHz.  
message, the simplest approach is to re-sample the audio at 44.1kHz and re-save the  
file.  
Scratch LIVE supports a maximum of 24 bits per sample of audio data.  
Unsupported file: This file uses more than  
24 bits per sample  
Scratch LIVE expected more data in the file, but found none. is could be because  
the file was incorrectly truncated or because the data in the file is corrupt, causing  
Scratch LIVE to incorrectly estimate the amount of data present in the file.  
Corrupt file: This WAV is incomplete.  
is file contains blocks of data that report their size to be zero. is message was in-  
serted to identify files that might cause lockups on previous versions of Scratch LIVE.  
Corrupt file: This file contains corrupt  
blocks.  
Scratch LIVE could not find any audio in this file. Please check to make sure this file  
contains audio in a format that Scratch LIVE supports.  
Corrupt file: This song contains no audio  
data.  
is file contains samples of audio that are too small to represent accurately and will  
therefore be truncated to zero. is should not result in any audible audio artifacts,  
but could cause audio dropouts on earlier versions of Scratch LIVE.  
Corrupt file: This song contains invalid  
samples.
