Scratch Amount
The Scratch knob controls the number of scratches on the
record. Higher values (knob to the right) result in more scratches on the record. Use
in combination with the Scratch Gain fader which controls the volume of the Scratch
samples.
Scratch Gain
The Scratch fader control increases the
volume of the Scratch samples. Note that you need to have the Scratch Amount turned on (to
the right) to trigger scratch samples, which can then be mixed with the music
using this Scratch fader.
Scratch Indicator LED Turns from red to dim green when you are mixing in scratch samples. At the moment that a scratch sample is actually being played, the LED turns from dim green to bright green. Note that depending on the latency of your sound card and system, there may be a delay between when you see the LED light up and when you hear the scratch sample played.
