A virtual ‘deck’ replicates the movementsof the control disc. Audio files loaded onto theVirtual Decks are then played back through theoutputs of the Sixty-Eight, with any manipulationof the control discs reproduced on the audio,effectively emulating vinyl control of the filesloaded in software.CONNECTING THE SIXTy-EIGHTFollow these steps to set up the Sixty-Eight forScratch Live, using up to four turntables or CDplayers to control the software playback:1.
