ADDITIONAL SETUPThis section covers general preferences andadjustments you can make to improve theperformance of Scratch Live. From the top of themain screen, click on SETUP to get to this area.HARDWAREUSB BUFFER SIzE (LATENCy)Scratch Live processes audio in small chunks.When smaller chunks are used, the movementof the record is translated into audio more often,which results in a lower overall system latency.However, this requires more processing andtherefore a higher CPU load, so lower buffer sizesettings require a more powerful computer toproduce uninterrupted audio. If you want tightercontrol, try decreasing this setting. On the otherhand, if you experience audio dropouts, youneed to increase this setting (or use a morepowerful computer).UPDATING FIRMWAREIf a firmware update is available after installinga new Scratch Live software release, anUpdate Firmware button appears in theHardware screen. The firmware upgrade takesapproximately 10 seconds, during which timethe Sixty-Eight will not be usable.If you are using a mixer that is not yoursand shared by other people, PLEASE DON’TUPGRADE their firmware without theirpermission, as the firmware with the Sixty-Eightcannot be downgraded to a previous version.Before installing a firmware update, be certainyou, and whomever else, will be using theversion of Scratch Live coupled with the updateor a newer version of Scratch Live, if available.INPUT SELECT STATUSThe input level currently set on the Sixty-Eightis displayed for each input. To change the inputlevel setting, use the switches on the Sixty-Eight.Choose P for Phono, S for S/PDIF and L for Line.When Phono is selected, the PhonoSensitivity setting is also displayed. Set thePhono Sensitivity to the same level of yourcartridge (see your cartridge documentation forthe correct value).HEADPHONE TONEThese controls adjust the Low and High tonecontrols to the headphone outputs.FLASHING DECk INDICATORDisplays a flashing white border around theVirtual Decks which currently have keyboard andcontrol strip focus.BUTTON BACkLIGHTBacklights the buttons on the Sixty-Eight foreasy visibility.SELECT PRIMARy DECkSSelect a combination of which two Decks to setas the Primary Decks.LCD CONTRASTThis control adjusts the contrast of the LCDdisplay in the FlexFX section on the Sixty-Eight.RECORDING BIT DEPTHChoose to record in either 16-Bit (CD quality,smaller file size) or 24-Bit (high quality, larger filesize). SEE ”RECORDING” ON PAGE 34.PLAyBACkTRACk END WARNINGEnable this option to flash the Virtual Deck asyou approach the end of the track.

Whenthis option is checked, you can only load a trackif the target deck is stopped.SORT CUES CHRONOLOGICALLyThe five cue points can be placed in any order,and can be dragged up and down if you wishto reorder them. If you prefer to lock them tochronological order, turn this option on.ENABLE HOT CUESWhen Hot Cues are enabled, you can set cuepoints simply by pressing the number keys 1through 0 (no ctrl modifier required) from yourkeyboard.
