 Grounding is extremely important when using

The Scratch Live control records and CDs
are pressed with an audible tone specically
developed for controlling the Scratch Live
software application.
The SL 4 interface converts the control signal
coming from each deck into digital audio, to be
sent via USB to the Scratch Live software, which
decodes that signal into a stream of information
based on what the DJ is doing with the control
disc. A virtual ‘deck’ replicates the movements
of the control disc. Audio les loaded onto the
Virtual Decks are then played back through the
outputs of the hardware, with any manipulation
of the control discs reproduced on the audio,
effectively emulating vinyl control of the les
loaded in software.
