Optional extra setup
• If you are using turntables, connect their ground wires to the grounding post of your DJ mixer.
• Connect the THRU OUTPUTS of the Scratch LIVE hardware to the mixer’s phono inputs when using turntables; connect these to
the mixer’s line inputs when using CD players. This allows you to bypass Scratch LIVE to play normal records or CDs.
• Connect a 9VDC external power supply (not included) to the Scratch LIVE hardware to power the THRU channels when USB
power is not present. This allows you to play vinyl (or CDs) when the laptop is not present, useful for permanent installations or
using more than one laptop. The power supply must be 9 volts DC, 300 mA minimum, using a P6 type barrel plug.
• Connect a dynamic microphone to the MIC INPUT of the Scratch LIVE hardware to scratch your own mic recordings as if they are
on vinyl.
• Connect a ¼" to ¼" cable from the MIC THRU jack on the Scratch LIVE hardware to the microphone input on your DJ mixer to
allow normal use of the microphone, independent of Scratch LIVE . (Note: power is required, either from the USB port or an external power supply.)
Manual-3
Setting up your turntables and mixer
1. Set the tone arms to the specific recommendations of the cartridge used, such that the needle never
leaves the record, but not heavy enough that it heats up significantly. Both produce poor tracking.
2. If the track plays backwards, you have connected the inputs from your turntables the wrong way
around. Left=white, Right=red.
3. Grounding is extremely important when using Scratch LIVE . Make sure you have good connections
from the ground wires of your turntables to the grounding post of your DJ mixer. All DJ mixers with
turntable inputs have built in grounding points for this purpose. If you do not ground your turntables
properly, the control signal will be noisy and the tracking of the record position will be erratic.
Tip: We recommend Shure M44-7 needles for use with Scratch LIVE , due to their high output volume,
excellent tracking and low record wear.
Setting up your CD players
Your CD players do not need any adjustment. Connect the output of your CD players to Inputs 1
and 2 of the Scratch LIVE hardware, and set the Input to Line Level in the Scratch LIVE setup.
Starting the software
Close all other programs on your Mac or PC.
When you load Scratch LIVE for the first time, you will see the following screen:
Manual-4
Calibrating Scratch LIVE
The Scratch LIVE hardware interprets the signal on record and communicates with the software. The signal needs to be clear for
Scratch LIVE to perform well. This section describes how to calibrate Scratch LIVE to optimize reading the control signal from your
turntables or CD players.
For best results, you should re-calibrate Scratch LIVE each time you move or make changes to your DJ equipment. To calibrate
Scratch LIVE , go to the setup screen by pressing the button at the top of the main screen, to the right of the Scratch LIVE logo.
Audio input level
By default Scratch LIVE is set to accept phono level inputs. If you wish to use CD players,
switch to line level input. This preference is stored when you exit Scratch LIVE .
Signal threshold
The first step is to set signal threshold. There is always a certain amount of background noise, particularly when using turntables
in a club environment. With a normal turntable setup, this background noise is transmitted through the body of the turntable and
platter to the stylus, and can cause stylus feedback. In Scratch LIVE , this can cause the errors on the reading of the position and velocity of the control record.
Place the needle on the record with the record stopped. Click the estimate button to measure the background noise and
estimate the appropriate threshold. Moving the threshold slider to the left will make Scratch LIVE more sensitive to slow record movement, but also more sensitive to background noise.
Tip: If the slider jumps to the far right, then you have a problem with noise in your turntables/CD players/mixer. Check all your
connections and make sure your equipment is well earthed. In some situations you will not be able to improve the signal quality, and
you will have to play on regardless. In this situation, stick to Relative mode. (See page Manual-11 for details)
Scope view
Once you have set the threshold, start both turntables. You will see green rings appear in the scope view, as shown below.
For optimal performance the inner ring should be as close to circular as possible. Use the scope zoom slider (1x to 16x) to zoom
in or out as necessary. Use the scope L/R balance and P/A balance controls to adjust the shape of the inner ring.
The number in the top left corner of the scope view gives the current absolute position within the control record or CD. The number in the top right corner is the current speed in RPM. In the bottom left is the current threshold setting, and the number in the
bottom right shows the percentage of readable signal – this number should be 100% when your system is calibrated properly.
Tip: if you have trouble getting the rings circular, you probably need to change your needles. If the image appears as a line, then
one of the channels of the turntable is not working.
Tracking light
The Tracking light on the main screen provides an overview of the signal quality. It should be
green when tracking correctly. If it is dim, or red, go back to the setup screen and check your calibration. If this does not help, check your hardware. Problems may be caused by dust on the needle, bad
cable connections or dirty control vinyl. Note that it is normal for the light to be red when scratching.”
Manual-5
Playing your first track
Now that you have calibrated Scratch LIVE , you are ready to play your first track. We will return to the setup screen later to set
general system preferences.
When you first run Scratch LIVE , your library contains only the pre-installed tracks. To import your own tracks, drag files and
folders directly from Windows Explorer (PC version) or Finder (Mac version) into the Scratch LIVE library.
You can also 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.
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 to load it onto both turntables.
Tip: Use the keyboard shortcut shift  to load the highlighted track on to the left deck, and shift  to load the highlighted track on
to the right deck.
To start playing a track, simply put the needle on the record and start the turntable. The track will start playing from the position dictated by the placement of the needle on the record – if you place the needle at the beginning of the record, the track will start
playing from the beginning. You can skip through the track by picking up the needle and placing it further into the record, just as
with regular records (This is known as needle dropping).
Supported file types
Scratch LIVE supports fixed and variable bit rate .MP3, .AIFF, and .WAV file types. iTunes™ library and iTunes playlists can be
automatically imported in the setup screen by clicking read iTunes library. You can also play audio direct from CD. See
Rescan 1D3 tags on page Manual-18.
Using tool tips
Click on the ? icon to enable tool tips. 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.
Manual-6
Playing tracks
When a track is loaded, the track name, artist,
length and BPM are displayed in the track title bar, and
the Virtual Deck shows a solid black line. The track will
start playing as soon as it detects the signal from the
record (or CD).
The control record
The control record has two sides. The first side is ten minutes long and contains the Vinyl
Scroll section. The second side is 15 minutes long. Scratch LIVE can be configured to work
with records playing at either 33 RPM or 45 RPM, depending on your preference.
The record has thin marks every minute, and a thicker mark every 5 minutes
(when playing at 33 RPM). These marks are to assist you when using needle
dropping to move through the track. These marks do not affect the playback
of the track.
Vinyl Scroll
Vinyl Scroll allows you to select and load tracks using only your
turntables (or CD player) – no contact with the computer necessary!
To use Vinyl Scroll with turntables, lift the needle off the record
and drop it into special “bonus track” section at the end of the record’s A side. The movement of the control disk now controls the
selected track within your library. Lift the needle out of the Vinyl
Scroll section of the record and into the lead out (between the
Vinyl Scroll area and the end of the record) to change crates or
iTunes playlists. Go back to the Vinyl Scroll area of the record to
choose a track within the crate or playlist. Once you have found
the track you wish to play, put the needle back at the beginning
of the record and it will load automatically.
This feature is available to CD users. Go to track 2 on the
control CD to access Vinyl Scroll. Find the track you want to load,
and go back to track 1. The track you selected will be loaded and
ready to play.
You can reverse the direction of Vinyl Scroll and set the sensitivity
in the setup screen (page Manual-17).
Virtual Deck
Virtual Deck shows everything about the speed and position of a track. As
the vinyl rotates, so does the line on the label. The 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. The time and remaining time are displayed in
minutes and seconds. You can also choose to display the turntable speed as a percentage pitch shift, or
the pitched BPM (BPM with pitch adjustment multiplier applied). If the track has no BPM information, percentage
pitch shift will be displayed. To display pitched BPM, go to the setup screen and tick show pitched bpm.
You can change the color of the record label by clicking on the Label
button to help identify records of different types. The color information is
stored with the file, and is displayed every time the song is loaded. A small
icon showing the label color is displayed left of the track information in the
main library.
The Virtual Deck also displays information to show you what control
vinyl you are using (e.g., CV01 A for the A side of the first control vinyl pressing). This information is useful if you have drift compensation enabled. See
page Manual-18 for more information about drift compensation.
If you are playing regular vinyl, notice that the Virtual Deck behaves
strangely as Scratch LIVE attempts to decode the incoming signal. This will
not cause any problems, but you may find it distracting. You can unload the
currently loaded track using the eject button next to each Virtual Deck.
To set Markers for cue points, see page Manual-15.
Tip: Use the keyboard shortcut shift-alt-arrow to unload a track from the Virtual Deck.
Manual-7
Visual aids
When the track is playing several waveforms are displayed.
Each shows a different aspect of the track being played.
Tempo Matching display
The 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.
Note that the tempo display is aligned with the beginning
of the bar, so the peaks keep their relative position as the track
plays. This display does not show the relative timing of the beats,
only the tempos of the tracks. The peaks will still line up when
the tracks are playing at the same tempo, but are out of sync.
Track Overview display
This view provides a complete overview of the waveform of
the track, and includes a marker to show the current position
within the track.
This view is useful for finding transitions within the track.
The waveform is colored according to the spectrum of the sound
– red representing low frequency bass sounds, green representing mid frequency sounds and blue representing high frequency
treble sounds.
You can jump to different positions within the track by clicking on the Track Overview display (disabled in Absolute mode).
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.
The overview will be filled when you load the track onto a
Virtual Deck. On slower computers, you should disable auto fill
overviews in the setup screen – with this setting disabled, the
overview will be filled as you play the track.

Manual-8
Track overview display
Main Waveform display
This 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 fine adjustments
to your position within the track. This applies to Internal mode
only, and may be useful if you wish to set markers in your tracks
without your turntables or CD players connected. The Main
Waveform is zoomed around the current position in the track.
See also: Internal mode on page Manual-11
Markers on page Manual-15.
Tip: Use the + and – keys to zoom in and out.
In the example below, the red part of the wave represents a
kick drum, while the purple part represents a snare drum
Kick Drum
Main waveform display
Snare Drum
Tempo Matching display
Beat Matching display
This view shows the position of beats within the track. When
beat matching, this view helps align the downbeats of the two
tracks. The markers are matched up when the two tracks are beat
matched.
Example
The 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 turntable 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 display. Remember that a kick or bass drum will be red in color,
and a snare drum will be green or blue.
This technique will by no means guarantee perfect mixes, but
may help to speed up the process of beat matching.
Beat matching display
Manual-9
Gain adjustment
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.
The level meter shows the level sent to the hardware interface —
after both individual channel gain and master gain adjustment.
Master Gain
The master output of Scratch LIVE can be controlled using the
master gain control. This adjusts the output volume of all tracks
played.
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 before
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. Highlight a track and press ctrl-o. This will
launch the player your computer has associated with the file type,
and start playback. Also applies to the import panel.
Manual-10
Scratch
LIVE modes
Scratch LIVE has three different modes of operation. You can
switch between these modes by clicking the mode buttons near
the Virtual Deck.
Absolute mode
Absolute mode is the default mode, and most closely resembles the properties of normal vinyl. The beginning of the track
is mapped to the start of the record, and by picking up the tone
arm and moving the needle to another part of the record (needle
dropping) you can move to a different position within the track.
Absolute mode faithfully reproduces the movement of vinyl
control records, including stops, starts, scratching, needle dropping, rubbing and other turntablist techniques.
When you reach the end of the record, Scratch LIVE automatically switches to Internal mode. This is known as Emergency Internal mode, and prevents long tracks from stopping when
you run out of record. You can switch from Emergency Internal
mode to absolute mode by lifting the needle and placing it in the
lead-in of the control record.
Note: Be careful when scratching near the end of the record
not to accidentally go past this point and into Internal mode
– the track will no longer respond to record movement!
Tip: Use the keyboard shortcut F1 (left deck) or F6 (right
deck) to switch to Absolute mode.
Relative mode
Relative mode observes the relative forward and backward
movement of the record, but does not take into account the position within the record. Relative mode disables needle dropping,
but allows skip-free scratching.
Tip: Use the keyboard shortcut F2 (left deck) or F7 (right
deck) to switch to Relative mode.
Internal mode
Internal mode allows you to play tracks without external
vinyl (or CD player) control. Internal mode has a start / stop
function and virtual pitch slider. Holding down the shift key
moves the pitch slider slowly. Holding the ctrl key and clicking
on the pitch slider resets it to 33 rpm or 45 rpm, depending on
which you are closest to at the time.
Scratch LIVE automatically switches to Internal mode when
the end of the control record is reached; you can switch back to
Absolute mode by placing the needle in the lead-in of the
control record.
If you switch from Absolute or Relative into Internal
mode, Scratch LIVE automatically adjusts pitch to maintain playback speed as set by the turntable.
Click on the waveform to ‘scrub’ or make fine adjustments to your position within the track. This may be
useful if you wish to set markers in your tracks, and don’t
have your turntables or CD players connected.
Note : If you play a track in Internal mode, and then
switch to Absolute or Relative mode, the pitch adjustment
will be dictated by the turntable, so there will be a jump
in pitch unless they are already perfectly matched.
Tip: Use the keyboard shortcut F3 (left deck) or F8
(right deck) to switch to Internal mode.
Repeat
Use the repeat function to repeat the song
across the entire length of the control record.
Tip: Short “ loop” samples can be turned
into a continuous track using repeat function. The loops need to be less than 10 seconds
long, and cut at the start and end of a bar.
Manual-11
Organizing your music
Scratch LIVE can support an unlimited number of tracks – the only limitation is the size of the
hard drive of your computer. A number of features are included to help you to keep your music
organized and find songs quickly and easily.
Grouping tracks into crates
Scratch LIVE supports several ways of organizing and sorting your file library. iTunes™ users
will notice that Scratch LIVE automatically incorporates your existing iTunes library and playlists.
Scratch LIVE uses digital “crates” for quick access to your favorite collections. There 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:
•
•
•
•
•
•
Hip Hop
UK Hip Hop
French Hip Hop
Instrumental Hip Hop
Old School Hip Hop
Hip Hop LPs
To make a new crate, click the + button. To rename a crate, double click the crate name.
You can change the order of tracks within a crate by dragging them up or down.
Tip: The allow file removal option in the setup screen also applies to removing (and
editing) crates. Uncheck this option to prevent changes to your crates. If you do delete a crate by
accident, you can get it back from the recylce bin / trash. Crate files have extension “ .slc”.
Sorting your files
The track information display area can be customized to display the columns listed below:

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 column,
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.
Using the song browser
The song browser allows you to filter your song list by Genre, BPM, Artist and Album. To turn the song browser on or off, click
the browse button.
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. This 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.
search box
To select which fields the search function will look through, click on the left hand side of the search box. The drop down menu
shows which fields are currently being used.
Press the x button on the right of the search box to clear the search.
Manual-13
The prepare window
The 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 window, or simply drag tracks onto the prepare button. These 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.
The review window
The review window shows the tracks you have recently played in the order in which they were played. 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 file information
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. This information is saved in the
file itself.
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.
Status icons
The leftmost column shows the status of each track. The image to the left shows 5 tracks with differing statuses.
From top to bottom:
• Scratch LIVE has detected some corruption in the MP3 file. If possible, re-encode the MP3.
• The track has been imported from the iTunes™ library.
• The track has been imported from the iTunes library, and Scratch LIVE has detected some corruption in the MP3 file.
Solution: If possible, re-encode the MP3.
• The track cannot be found. Most likely the file has been renamed or moved.
• Scratch LIVE is trying to import a track from the iTunes library, but cannot find the file.
Display album art
MP3 files can contain album art information. To display this album art, click the show album art button. There are many
third party applications available for adding album art to MP3s. We recommend Apple’s iTunes™.

Markers
You can set up to five visual markers within each track to
help you to find important cue points. Use the set new button
to place a marker.
Click the arrow to the left of each marker to jump to that
marker (rel. and int. mode only). You can also jump to markers using keyboard shortcuts – 1 through 5 for the markers on
the left deck, and 6 through 0 for the markers 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 marker – you
are at the marked point when the stripe is one solid color and at
the 12 o’clock position.
As the record plays on beyond the position of the marker, the
colored bar will shorten by a fifth for each rotation. Likewise,
as you approach the marker, the color will grow by a fifth each
rotation. For example, the picture below right shows the record
just before the end of the 5th rotation before the marker.
Each marker can have a different color. To change the color
of a marker, click on the colored square and choose a new color
from the drop down menu.
To remove a marker, use the x button on the right hand side
of the marker panel.
Markers are automatically ordered by their position within
the track. If you load the same track on to both decks, you will
be able to add or modify markers from either deck.
Tip: use the keyboard shortcuts ctrl-comma (for left) and
ctrl-dot (for right) to place markers.
The stripe is a solid color at the marker point
The stripe grows a fifth by each rotation closer to the marker point
Recording from a microphone
Scratch LIVE allows you to record from the Mic Input and scratch it immediately as if it were on vinyl. Use the mic input level
indicator on the screen and the MIC GAIN control on the Scratch LIVE hardware to adjust the mic recording level. Click the mic
rec button to start recording, and click the mic rec button again to stop recording. The mic rec button flashes during recording.
To play the recording, type in a name for the recording and click the save button. The recording is automatically placed in a
crate named Recorded. If that crate does not already exist, it will be created. To start a new recording without saving, simply reclick the mic rec button.
Recordings can be loaded onto the decks, renamed and managed like other files. Recordings are saved in ‘My Documents\My Music\ScratchLIVE\Recording’ on a PC, and ~/Music/ScratchLIVE/Recording/ on a Mac. Recordings are saved as 16-bit mono AIFF files.
To quickly load a recording on to a deck without saving it first, click the mic rec button to start the recording, and then use
the short cut keys shift  or shift  to load the track. If you load the recording in this way, the recording will not be added to the
library, and will be discarded on exit. To keep the recording, copy the file found in ‘My documents\My Music\ScratchLIVE\Recording
temp’ on PC and in ‘~/Music/ScratchLIVE/Recording temp on a Mac.
Tip: Use keyboard shortcut ctrl-n to start a new microphone recording.

Additional setup
This section covers general preferences and adjustments you can make to improve the performance of Scratch LIVE . From the
main screen, tick setup to get to this area.
Vinyl scroll sensitivity
Vinyl Scroll allows you to load a new track without touching the computer, simply by lifting the needle and placing it in the special section of side A of the control record. For a full description, see page Manual-7. This setting allows you to adjust the sensitivity
of Vinyl Scroll, so that you can control the amount of record movement required to move between tracks.
Read iTunes™ library
Existing iTunes users will recognize many features from iTunes. Scratch LIVE can read the iTunes library format, and will automatically 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.
Track end warning
Enable track end warning to flash the Virtual Deck as you approach the end of the track. The label will start flashing 20 seconds
from the end of the record. The track end warning does not apply to any tracks under 1 minute long.
Play from start
Enable this to start all tracks from the beginning when loaded in Internal or Relative mode. If this setting is not enabled, freshly
loaded tracks will continue to play from the point the last track was at.
Reverse vinyl scroll
This setting allows you to reverse the direction of Vinyl Scroll. For a full description, see page Manual-7.
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.
Allow file removal
Enable this setting to remove files and crates from your library. Disable to lock your library and prevent accidental file or crate
deletion while using Scratch LIVE . Disabling this setting will also lock all file tags and crate names, so that no text can be changed.
Manual-17
Drift compensation
Scratch LIVE works by tracking a control signal that is pressed onto vinyl records, and applying that movement to audio files. It
does this exceptionally accurately at low and high speeds, both forwards and backwards. Users have reported drifting of tracks during
long mixes, and after careful investigation we have found the lathe that mastered the original CV01 control records induced pitch
variations in the vinyl master.
Because every CV01 control record pressed had the same pitch variation, it is possible to compensate these variations in software.
To turn drift compensation on, tick drift compensation. The drift compensation is unique
for each side of the record. When you turn drift compensation on, notice the letter A in the Virtual Deck, indicating drift compensation is enabled for the A side (10 minute side). To compensate for drift on the B side, place the needle anywhere after the 10 minute mark on the B side. To
switch back to drift compensation for the A side, place the needle into the Vinyl Scroll area of the
A side.
This issue only affected the first batch of control records labelled CV01. If you are using control records from a later batch with Scratch LIVE version 1.2 or greater, you do not need to have
drift correction enabled. The new corrected vinyl label reads CV02, with “second edition” on the
upper right of the sleeve. You may purchase “second edition” vinyl from the Rane website if you
are in the USA. Outside of the USA, call your distributor.
If you are using the control CDs, do not use drift compensation.
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.
Show pitched BPM
Enable this option to show pitched BPM on the Virtual Deck. If this option is not selected, the turntable speed as a percentage
shift will be shown. The pitched BPM is calculated from the BPM in the file tag, and the turntable speed. If no BPM tag is present in
the file, the percentage pitch shift will be shown.
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). These 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.
Maximum screen updates (per second)
This feature allows you to throttle back the screen refresh rate. Users with slower computers might like to do this if they are having performance issues. It could also be useful if you want to limit Scratch LIVE’s processor usage, for example if you are running a
recording program at the same time. The default setting is 60 Hz, or refreshed 60 times per second. This setting applies to the entire
screen (i.e. the Virtual Decks, the Waveforms, the library, and the setup screen).
Track start offset
If you find that you have cue burn at the beginning of the record, you will notice that the tracking will be poor at this point. Use
the slider to offset the start point, so that the track will start playing from a point further into the control record.
USB audio buffer size
Scratch LIVE processes audio in small chunks. When smaller chunks are used, the movement of the record is translated into audio
more often which results in a lower overall system latency. However, this requires more processing and therefore a higher CPU load,
so lower buffer size settings require a more powerful computer to produce uninterrupted audio. If you want tighter control, you
should try decreasing this setting, on the other hand, if you experience audio dropouts, you need to increase this setting (or use a
more powerful computer).
Build overviews
If you run Scratch LIVE with the hardware interface disconnected, 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. The track name (and location) are
shown in the bar immediately below the button. Below this are three more bars. The first bar shows track reading progress, the second bar shows overview building, and the third bar shows track writing progress. Use the the build overview function to prepare the
overviews of all your tracks before you play.
Manual-18
USB dropout indicator
The USB dropout indicator on the main screen is a useful trouble shooting tool if you have problems
with audio dropouts. Such dropouts are caused by an interruption in passing the audio to the Scratch
LIVE hardware interface. If such an interruption (or dropout) occurs, a red light will appear briefly, just
to the left of the Scratch LIVE logo at the top of the screen. The light will be red for one second, and then
orange for four seconds.
If you do experience USB drop outs:
• Increase the USB audio buffer size (in the setup screen).
• Try closing other applications that are running at the same time as Scratch LIVE .
• Try turning off background tasks, for example, wireless networking.
• Visit the forum at scratchlive.net, and try some of the computer optimization tips in the Tips and Tricks section.
• If your CPU load is very high, try decreasing the maximum screen updates (in the setup screen).
Advanced Techniques
Scratch LIVE contains features that allow some advanced techniques. These techniques will require practice to perfect, but will
allow you to perform feats not possible with normal DJ equipment.
Mixing with only one turntable
The single turntable technique allows you to mix as if you had two turntables, using just one. If one of your turntables is not
performing properly, or if you only have one available, you will be able to continue to mix the way you are used to.
The following is a step-by-step description of mixing using a standard 2-channel mixer, with one turntable set up on the right
hand side of the mixer. In this example, all mixing is done with the mixer crossfader.
1. Load a track onto the right deck in Scratch LIVE and play it in Absolute mode. The crossfader is set to the right hand side.
2. Put the left hand deck into Internal mode and load a track.
3. Flick the reverse input control switch. The physical record now controls the left hand deck in Scratch LIVE, and the right
hand channel of Scratch LIVE plays on in Internal mode.
4. Cue the record and mix in the track. Note that you will be using what feels like the wrong channel of your DJ mixer to do this
– the crossfader will be moving away from the turntable.
5. Having completed the first mix, flick the reverse input control switch. The track you just mixed in will play on in Internal
mode, and the physical record is now back to controlling the right hand deck in Scratch LIVE .
6. Load a track on to the right deck in Scratch LIVE , and mix as normal.
7. Flick the reverse input control switch.
8. Load a track on the left deck, and mix — moving the cross fader the wrong way.
9. Flick the reverse input control switch, and repeat.
Swapping the turntables in the middle of a mix
This technique is intended for scratch DJs who favor one hand over the other. For example, say you are a right handed DJ (meaning that you like to use the crossfader with your left hand, and move the record with your right hand), occasionally you will be
playing a record on the right turntable, and wish that it was on the left turntable so that you could scratch over it on the right. This
technique will allow you to swap the turntables.
The following is a step-by-step description of scratching using a 2-channel mixer fitted with a crossfader reverse switch (also
known as a “hamster” switch). In this example, the user wants to have the crossfader in the left hand, and record on the right.
1. The track is playing on the right hand turntable. The scratch sample is loaded on the left side. These need to be swapped.
2. Set the left deck in Scratch LIVE to Internal mode and close the left hand vertical fader on the DJ mixer. (Alternatively, you could
set the left deck to Relative mode and start the turntable, but you would have to match the tempo with the other turntable).
3. Flick the reverse input control switch.
4. Move the crossfader to the center position.
5. Activate the reverse hamster switch.
6. Move the crossfader to the left.
7. You can now scratch as normal — but remember, the vertical faders, EQ and gain are reversed!
8. To get back to how you started, close the left vertical fader.
9. Move the cross fader to the middle.
10. Deactivate the hamster switch.
11. Move the crossfader to the right.
12. Flick the reverse input control switch.

Troubleshooting and Frequently Asked Questions
Scratch LIVE hardware is not recognized
It takes five seconds for Scratch LIVE to detect the hardware. The hardware can be unplugged at any time; you do not need to exit
Scratch LIVE before disconnecting the hardware. 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.
The audio playback is dropping out / clicking / popping
Scratch LIVE is not getting a clear signal from the record, or your computer is not able to process the information quickly enough.
Go to the setup screen and check the scope views. When the record is playing, the circles should be round, and the value in the
bottom right corner should be 100%. If this is not the case, you need to calibrate. See page Manual–5 for details.
You should also try increasing the USB audio buffer size if your computer is close to the minimum spec.
Clean your needles! This is the most common cause of audio drop-out. Because you are playing the same record over and over,
the needles will get dirty more quickly than usual.
The threshold goes to the far right when I click the estimate button
Make sure the needle is on the record and the record is stopped when you click the estimate button. If the slider goes hard
right and stays there, you most likely have an earthing problem with your turntables/mixer. If you cannot eliminate this problem, use
relative mode over absolute mode.
The tracks are playing backwards!
The inputs (from the turntables or CD players) are the wrong way around.
I can’t get the Scope View to show nice clean circles
Select phono as the audio input level in the setup screen if you are using vinyl. Check your needles and make sure they are
clean. If the circles look fuzzy, try cleaning your control record. If the Scope View shows a line instead of a circle, Scratch LIVE is only
receiving a signal from one channel — check all your cables, and the connection between your cartridges and the tone arm.
You can order replacement control records from your local distributor. You may also order these in the online store at www.rane.
com if you are in the USA.
Scratch LIVE makes a strange “digital” noise, even when no track is playing
Scratch LIVE is interpreting background noise as record movement. Go to the setup screen and move the threshold slider (located to the left side of the estimate button) to the right until the noise stops.
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. This may take a few seconds for longer
files. After the first load, it should load instantly. See Build Overviews 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?
The file may be damaged. Please go to the forum at scratchlive.net and notify the support team that you have a bad file. By reporting damaged or corrupt files, you will help the developers to improve Scratch LIVE’s ability to play damaged MP3 files in the future.
My USB will only output audio for about ten seconds then quit. I can still control Scratch LIVE with the control records, but I get
no audio output
This is a known Windows XP bug. Included in the Windows Update SP1 (Service Pack One) download is a fix for the XP USB
1.1 bug. For more information visit www.support.microsoft.com
Scratch LIVE freaks out when I use the master tempo (key correction) function on my CD player
Scratch LIVE interprets the signal coming out of the CD player, and uses this information to control the play back of the files on
your computer. Any audio processing performed on the signal before it reaches the hardware interface, such as key correction, will
scramble the signal making it illegible to Scratch LIVE . Key correction will be built into Scratch LIVE in the future.
I get a loud screeching sound like a fax machine and no music, what am I doing wrong?
That is the sound of the control signal — make sure you are listening to the line outputs of the hardware interface.
Manual-20
Can I use one turntable and one CD player?
Yes. You need a phono preamp to boost the signal from the turntable to line level, and you need to set the input to line in the
setup screen. Rane’s PS 1 Phono Preamp is a good solution.
When I do transform scratches (switching between phono and line level inputs) I hear a crazy noise; what’s happening?
When you switch to phono level, you will hear the sound of the control vinyl. If you want to use the transform switches to
scratch, use separate channels on your mixer if you have more than four channels, or disconnect the phono thrus if you have a two
channel mixer.
I want to backup my library and crates or move them to another machine, so where are they stored?
Your database and crates are stored in the folder Home\Music\ScratchLIVE on a Mac, and My Documents\My Music\ScratchLIVE 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.
What needles are best for use with Scratch LIVE?
We recommend Shure M44-7 needles for use with Scratch LIVE , due to their high output volume, excellent tracking and low
record wear.
I have cue burn at the beginning of my control record, does that mean I need to replace it?
No, use the track start offset function (in the setup screen) to move the point at which tracks begin to a position further
into the vinyl.
Why do none of the songs I have imported from iTunes show up in Scratch LIVE?
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, 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.
