When using in combination with the sound device of another unit, the preparations in "1" below are not necessary, but in principle we recommend using this unit's built-in sound card.1. To use the USB sound card function
First, the dedicated driver software must be installed on the computer. For instructions on installing the driver software and details on operations with the USB sound card (audio interface) function, see "Connecting to the control panel" in this unit's operating instructions. For the settings on the DJ software, see your DJ software's operating instructions.
2. Using the USB-MIDI interface function
For details of operations with the MIDI interface function, see "Operating DJ software using the MIDI function" and "Operating an external MIDI sequencer" in this unit's operating instructions. For the settings on the DJ software, see your DJ software's operating instructions.Net Number : 39 - Q3 What are the specifications of the USB sound card (audio interface) function?

Normal operation is not guaranteed in this case. We strongly recommend connecting only this unit to the computer's USB port when using this unit.
Net Number : 44 - Q5 Can this unit be used for MIDI control of DJ software or MIDI-compatible devices?
-
A5
Yes.
This unit outputs MIDI signals synchronized with operation of buttons and controls, so it can be used to control DJ software on the computer connected to the USB port or MIDI-compatible devices (external MIDI sequencers, etc.) connected to the MIDI OUT (DIN) terminal. In order to use the MIDI functions, in addition to cable connections, settings must also be made on the respective devices. For instructions on making the MIDI output settings, see "Operating DJ software using the MIDI function" and "Operating an external MIDI sequencer" in this unit's operating instructions. For instructions on making the settings on the DJ software or external MIDI sequencer, see the respective device's operating instructions.Net Number : 45 - Q6 Tell me some DJ software programs that support MIDI control.

MIDI is a universal standard, so there are many DJ software programs that support MIDI control, such as the Native Instruments "TRAKTOR" and "TRAKTOR SCRATCH" series, Atomix "Virtual DJ", etc. For details, contact the DJ software manufacturer.

With DJS, this unit's USB sound card (audio interface) function can be used, but DJS control using this unit's MIDI control function is not possible (because DJS is not MIDI-compatible). Use the mouse, keyboard, etc., to operate DJS.
