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 simultaneously 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.

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

Manual-5

Page 8

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.

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.

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 installation, 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

Before launching the Scratch LIVE software, close all other pro-

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 highlighted track on to the left deck, and shift  to load the highlighted track on to the right deck.

Preparing your files

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. 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.

Supported file types

Scratch LIVE supports xed and variable bit rate .MP3, Ogg Vorbis, .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.

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.

Tip: Holding the mouse over the ? button with tool tips turned on will show you a list of all keyboard shortcuts.

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 automatically.

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.

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 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.

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.

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.

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

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.

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.

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.

Tip: use the keyboard shortcuts ctrl-comma (for left) and ctrl-dot (for right) to place cue points.

Note: Cue point shortcuts are ﬁxed to their position on the keyboard, not the key numbers, so that they are the same regardless of keyboard language. Keep

Caps Lock on when using these

shortcuts.

Manual-9

Page 12

The stripe grows a fth by each rotation closer to the marker point

The stripe is a solid color near the marker point

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.

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 n bars will create a loop start point

from the nearest beat to the playhead (within reason), and set a

loop endpoint n bars in the future. Pressing auto-loop 1 while auto-loop 1 is 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.

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 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' button 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-10

Page 13

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 representing mid frequency sounds and blue representing high frequency treble sounds.

You can jump to dierent positions within the track by clicking 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.

Tempo matching display

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.

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.

Main waveform display

Manual-11

Page 14

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

crtl key and clicking on the waveform.

the

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.

Kick Drum

In this example, the red part of the

wave represents a kick drum, while the

purple part represents a snare drum

Snare Drum

Tempo Matching display

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.

Beat matching display

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.

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 MIDI to other controls

Controls which aren’t normally visible are available for assignment 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

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.

LIVE screen controls have additional functionality

Assigning Controls

To enable MIDI assign mode, click the MIDI button

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 control. 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.

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).

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 computer. 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.

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

Manual-14

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.

Page 17

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.

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 window, 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.

when no song is loaded, for ﬁnding the BPM of regular records,

for example.

Seee auto BPM on page 7 to automatically ll in these tags.

Status icons

e leftmost column shows the status of each track. e image to

the left shows 5 tracks with diering statuses. From top to bottom:

• Scratch LIVE has detected some corruption in the MP3 le. If possible, re-encode the MP3.

• e track has been imported from the iTunes™

library.

• 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™.

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

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-

. 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.

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 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

track end warning

Enable track end warning to ash the virtual deck as you approach the end of the track. e label will start ashing 20

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 le), 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

applies to all cue points (1...0) and cue controls (QWERTY etc). See page 19.

lock playing deck

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.

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.

use 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 / o, and the target gain changed on the y. If

you change the target gain while a song is loaded to a deck, the

change will apply the next time a song is loaded.

When a track is in auto gain mode (auto gain is turned on

and the track has an auto gain setting), the track gain knob ap-

pears depressed to provide visual feedback that auto gain is in eﬀect for that track. To ﬁne tune your gain values, you can still change each ﬁle by the gain knob. To reset the gain to the calcu-

lated auto gain value, Alt-Click the gain knob.

Play from rst cue point

Enable this option to start all tracks from the ﬁrst cue point when loaded in rel and int modes. is setting overrides the play from

start

option.

braking

is controls how fast the deck stops when play is stopped. Counterclockwise, the stop is immediate. Clockwise rotation increases the stop from a ﬁnger grab all the way to a slow turntable power-down.

audio output

Sets the audio output to mono or stereo

hi- 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.

play from start

Enable this to start all tracks from the beginning when loaded in rel and int modes. If this setting is not enabled, freshly loaded tracks will continue to play from the point the last track was at. is

Library

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.

identify all the ﬁles that Scratch 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.

relocate lost les

If you’ve moved some ﬁles which are already in your library, they

will show up as not found and displayed in pink. Drag a folder from nder (mac) or explorer (windows) on the relocate lost

ﬁles

button to search it and any sub-folders, for ﬁles currently marked as not found in your library to update them with their new location.

LIVE can’t ﬁnd (for example

protect library

Uncheck this setting to remove les 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 le tags and crate names, so that no text can be changed.

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.

show all le 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 15, you can drag crates into other crates to make subcrates. If you have the “include subcrate tracks” op-

tion turned on, any crate will also display the contents of all its subcrates.

auto ll 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.

Display

user interface settings

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 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. e default setting is 60 Hz, or refreshed 60 times per second. is setting applies to the entire screen (i.e. the Virtual Decks, the Waveforms, the library, and the setup screen).

audio cache (seconds)

Use the slider to set the amount of audio that is loaded into memory. A small audio cache will place less load on your computer, 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.

horizontal waveforms

Check this option to display the main waveform view horizontally. e waveform will expand to ll available screen space. If

you are using a widescreen computer, increase the audio cache

size to make the waveform bigger.

import AAC les

Turn this option o if you do not wish to import AAC les into your library. Changing this option will cause your iTunes library to be reloaded if you have the 'read iTunes library'

option turned on.

rescan ID3 tags

Click this button to force Scratch LIVE to re-read all le 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

Corrupt file descriptions and diagnoses

Corrupt le: This MP3 contains invalid frames.

Corrupt le: This le contains corrupt frames that may result in audible glitches.

Corrupt le: This le has been split. You should check the beginning for audio glitches.

Corrupt le: This MP3 contains frames with corrupt data.

Corrupt le: This MP3 lost syncronization between the frame index and the frames.

Corrupt le: This MP3 is completely invalid and is not playable.

Corrupt le: This le contains invalid audio data.

Corrupt le: This MP3 contains no valid frames.

Unsupported le: This MP3 contains multiple layers.

Unsupported le : This le is more than 2GB in size.

Unsupported le : This le has data blocks greater than 2GB in size.

Corrupt le: This WAV contains no valid chunks.

Unsupported le: This le's data is not in PCM format.

Unsupported le: This le has a sampling rate greater than 48kHz.

Unsupported le: This le uses more than 24 bits per sample

Corrupt le: This WAV is incomplete.

Corrupt le: This le contains corrupt blocks.

Corrupt le: This song contains no audio data.

Corrupt le: This song contains invalid samples.

is MP3 contains frames which do not conform strictly to the ocial MP3 specication. Scratch

LIVE can not be certain that this le will play back 100% accurately.

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.

e rst MPEG audio frame in this le 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.

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.

is is a rare message and you should not see this. Do notify us if you see it and please send us the le that caused the message to appear so we can x the problem.

Self explanatory. Possible causes are disk bad sectors, le system corruption, wrong le types, wrong le extensions, etc

Scratch

LIVE encountered a lot of invalid data while looking for audio in this ﬁle. is

message alerts you to the fact that the le you're trying to play contains corrupt data.

is may, or may not, aﬀect playback.

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.

While scanning this le, 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.

Self explanatory. At the moment, Scratch size (or larger).

is le contains chunks of data that are larger than 2GB. Scratch LIVE does not sup- port les that are more than 2GB in size.

is WAV le contains no recognizable WAV data. It is quite possible that this might not be a WAV le.

WAV les can contain data in several formats. Scratch LIVE only supports WAV les that contain data in the PCM format.

Scratch LIVE does not support sampling rates greater than 44.1kHz. If you see this 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.

Scratch LIVE expected more data in the le, 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.

is le contains blocks of data that report their size to be zero. is message was inserted to identify ﬁles that might cause lockups on previous versions of Scratch

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.

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.

LIVE does not support les that are 2GB in

LIVE.
