In the tools area you can select sample effects and play them on the turntables. In addition you can record the playback of the turntables, post-edit the scratches added to the recording in the Nero ScratchEditor, and record actions on the mixing console.   
The following setting options are available in the tools area:
Button

Button
Rewinds the recording.
Display field

Button
Hardware Learn
Establishes a connection between a control element on the DJ hardware and a control element in the ScratchBox.
This button is only active if DJ hardware is connected. 
Button
ScratchEditor
Opens the Nero ScratchEditor window.
In the Nero ScratchEditor you will see a curve for each turntable. At normal play speed the curve runs linearly at 100% of the y-axis.  
Scratches are displayed in the curve as deflections in the positive and negative % range. Negative deflections mean that the audio file is played in reverse for this time, positive deflections mean that the au-dio file is played faster.
The x-axis therefore describes the point in time, and the y-axis de-scribes the play speed of the audio file at this point in time.
