Can software other than the included TRAKTOR SCRATCH DUO 2 be controlled?

This unit can be operated as a general use USB-MIDI controller. MIDI is a universal standard, and many types of DJ software, such as Atomix' "VIRTUAL DJ", MIXVIBES' "CROSS", etc., in addition to Native Instruments' TRAKTOR 2 and TRAKTOR SCRATCH 2, support MIDI control. For details, contact the DJ software's manufacturer.
