I would like to use my DJ application. Is this possible simply by connecting this unit and the computer with a USB cable?

Settings must be made on this unit and on the computer beforehand.
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 "Installing the driver software","About the setting utility software" in this unit's operating instructions. For the settings on the DJ application, see your DJ application's operating instructions.
2. Using the USB-MIDI interface function
For details of operations with the MIDI interface function, see "Operating DJ application using the MIDI function" in this unit's operating instructions. For the settings on the DJ application, see your DJ application's operating instructions.
