Features:

• Record button: It records the input signal (you should click this prior to make any scratch).
• Scratching big slider: to do the actual Sxratches.
• Volume, Pitch and Smooth buttons (smoothes the scratch movements made on the big slider).

Usage:

• Load Sxratch so it receives audio and MIDI keyboard data at the same time.
• Record any input signal using the "rec" button.
• Move the scratch slider while you press any MIDI key. Keys acts like the fader on a DJ mixer, and the big slider acts like your fingers over the vinyl.
• Adjust smoothing to your taste.
