To use MIDI over USB, simply connect the USB port on your device to a USB 2.0 port on your computer. Your device is a class compliant MIDI device which supports MIDI over USB, and as such will require no drivers in order to be recognised by most DAWS as a MIDI input/ output. This allows you to both input MIDI to your DAW from your device, and also send MIDI from your DAW to your device.
