Drivers

You can download the latest Windows driver from the manufacturer’s website. The Scratch is class complaint on Mac and Linux.

Audio Setup

The mapping relies on the following channel assignments:

Output Channels	Assigned to
1-2	Master
3-4	Headphones

Input Channels	Assigned to
1-2 (CH 1 Line/Phono)	Vinyl Control 1
3-4 (CH 2 Line/Phono)	Vinyl Control 2
5-6 (Mix)	Record/Broadcast

The microphone, and external inputs are mixed together in input channels 5-6, so Mixxx can record and broadcast them.

The knobs for MASTER, BOOTH, MIC LEVEL, MIC TONE and CUE GAIN are controlling the hardware mixer of the built-in audio interface. Hence, turning the knobs will not change values in the Mixxx GUI and you’ll need to set the Mixxx knobs to their default values when using the controller:

Set the master/booth/headphones/microphone levels to 100% (knob center position)

Shënim

The PC / LINE/PHONO switches work only if the Vinyl Control input channels are assigned to software inputs. So even if you do not intend to use timecode vinyl but want to pass through line or phono inputs directly to the left/right deck, you need assign these channels in the Sound Hardware preferences.

CUE mode: Pads 1-4 trigger the respective hotcues, and if no hotcue point is set on that pad, will set a Cue point in the respective pad/slot. Holding SHIFT while pressing a pad will clear the Cue point from that pad.

SAMPLER mode: Press pads 1-4 to trigger samples loaded into the sample slot. Hold SHIFT while pressing a pad to stop the sample playback once triggered.

ROLL mode: In this mode holding pads 1-4 activates a loop roll of varying sizes. Release the pad to exit the loop roll.
