Ifa button is on, USB playback is disabled andthe SL 4 input is fed to the output.• Sample Rate indicators are read-only, showingthe sample rate selected on the SL 4.• USB Port Status indicators are read-onlyand on when a USB port is connected andcommunicating with the SL 4.• Buffer increases or decreases the USB driverbuffer size. The SL 4 drivers run very reliablyat latencies below 8 milliseconds. However,computer performance and available resources(number of apps running) may adversely affectstreaming audio. If pops and clicks are heardin USB audio, try increasing the buffer size. InASIO, total round-trip latency = buffer size +device latency. In Core Audio, total round-triplatency = buffer size + software applicationlatency + device latency. SL 4 latency is 1.3ms at 48 kHz and 0.8 ms at 96 kHz.• If the SL 4 firmware on your computer is newerthan installed in your SL 4, the Update DeviceFirmware panel is enabled. Pressing theUpdate Firmware button updates the SL 4firmware to the newer version installed withyour driver.Check for the latest download version of ScratchLive software at serato.com. If it is newer thanwhat is on your CD-ROM, we recommendinstalling it instead.Mac1.

Once theinstallation is complete, Scratch Live will appearin your applications list. You may like to dragthe Scratch Live icon to your dock for quicklaunching.3. Plug in your SL 4. No extra hardware or driverinstallation is required.WindowsIt is important that Windows users install theSL 4 drivers as well as the Scratch Live software.The easiest way to do this is to allow the ScratchLive installer to do all the work.1. Connect your SL 4 before you insert yourinstallation CD. When you first connect it,Windows will attempt to install the drivers viathe hardware wizard. Cancel and close thehardware wizard.Because the SL 4 was connected prior toinstalling Scratch Live, no extra hardwareinstallation is required.NOTE: Select the custom install option if youwish to change the installation location ofScratch Live.Additional Windows DriversThe driver updater can install drivers for differenttypes of Scratch Live hardware, not just theSL 4. For example, if you play at a club that usesa TTM 57SL mixer, you can add its driver to yourcomputer.Connect the new Scratch Live hardware toyour computer’s USB port. Cancel and close thehardware wizard when it appears.With your hardware still connected, run theScratch Live driver updater. This is usuallylocated in:C: > Program Files > Serato > driver_updater32.exeor for 64-bit systems:C: > Program Files (x86) > Serato > driver_updater64.exe.Starting Scratch LiveClose all other programs on your Mac or PC.When you load Scratch Live for the first time,you willsee thisscreen.8RANE SL 4 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.2.2
Using the Tool TipsClick on the ? icon to enable tool tips. Tool tipsprovide a handy way to learn the various featuresof Scratch Live. Move the mouse over a sectionto bring up a context-sensitive tool tip. Holdingthe mouse over the ? button with tool tips turnedon will show you a list of all keyboard shortcuts.Tool tips are available in several languages.Scratch Live displays tool tips in the languageyour computer is set to. If your language is notavailable, the tool tips are displayed in English.Virtual Deck SetupIt’s important to understand how your turntablesand CD players are connected to each VirtualDeck in Scratch Live before calibrating or playingtracks. These options allow you to customize thelayout of your DJ setup. We recommend learningScratch Live with just two decks.Starting with two turntables or CD players,select these as your “Primary Decks.” In a multidecksetup, this defines the sources you will playthe majority of your tracks from. Select PrimaryDecks in the Hardware tab of the Setup screen.See “Select Primary Decks” on page 32.To set a USB Source in Scratch Live, click theUSB Source dropdown box above each VirtualDeck. See “USB Sources & Analog Inputs”on page 13.Change your Display Mode toClassic Vertical mode if you don’t seethe dropdown above the Deck. See “DisplayModes” on page 15.Start with the Left Deck, select “Channel 1.”This Deck is now controlled by the turntable / CDplayer plugged into Input 1 on the SL 4, and theaudio from Scratch Live will be sent to Output 1.On the Right Deck select “Channel 2.” ThisDeck is now controlled by the turntable / CDJplugged into Input 2 on the SL 4, and the audiofrom Scratch Live will be sent to Output 2.Changing the Display to 4-Deck StackMode will allow you to see and assign allfour Decks at once. Your Primary Decks will havea white border around them. Repeat the abovesteps for the remaining two Decks.CalibratingScratch LiveSince Scratch Live is controlled by an analogsignal, there is no guarantee of what state thatsignal will be in by the time the software gets tointerpret it. Therefore, Scratch Live needs to beable to handle a wide range of signals, and beconfigurable to use them optimally. Calibratingis just configuring the software to your situation.Calibration is equally important for both vinyland CD users of Scratch Live.There are two parts to the Scratch Live controlsignal: The directional tone, and the noise map.Listening to the control vinyl, the directional toneis the 1 kHz tone. The noise map sounds likerandom noise over the top of the tone.The directional tone provides the currentspeed and direction of the record, while thenoise map tells the software precisely where onthe record the needle is currently.The Noise ThresholdA threshold is a lower limit, below which aprocess will not occur. In the case of ScratchLive, the noise threshold is the limit below whichthe input signal will not be interpreted as controlsignal; in other words if it’s below the threshold,it is considered noise and ignored.This setting is necessary because a stylus isvery sensitive, and will inevitably pick up noisefrom the environment as well as the signal on therecord, especially in the noisy environment of alive show.How to Calibrate Scratch LiveSwitch between calibrating the Primary andSecondary Decks by clicking the Primary andSecondary buttons above the scopes.With music playing in the background (fromany source), put your needle on the record withthe turntable stopped. If you are using CDplayers, the same rules apply. Have the CD deckpaused or stopped while calibrating. Ensure thePhono / CD switch on the SL 4 is set correctly.Click and hold the Estimate button until theslider stops moving. Moving the threshold sliderto the left will make Scratch Live more sensitiveto slow record movement, but also moresensitive to background noise.Repeat the process for each deck.Things to remember:• Your needle must be on the record.• Your turntable (or CD player) must bestationary.• The background music playing must be at asimilar level to which you will play your set at.• Calibrate Scratch Live every time you play.TIP: If the slider jumps to the far right,then you have a problem with noise in yourturntables/CD players/mixer. Check all yourconnections and make sure your equipmentis well-grounded. In some situations you willnot be able to improve the signal quality, andyou will have to play on regardless. In thissituation, stick to REL mode. See “CalibrationTroubleshooting” on page 10.The ScopesThe scopes on the Setup screen in Scratch Livedisplay the input signal as a phase diagram. Thekey factors to look at on the scope display arecrisp clean lines, round shape, and the trackingpercentage in the lower right corner.RANE SL 4 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.2.2 9
