1. As MIDI out device this USB Sound device should be selected (U-Mix)
2. MIDI Setup: For each assigned button there has to be the same button assigned again but as Control Type 'Output'. For example Low Kill assigned on the lowkill button, dublicate this MIDI command but change as control type 'Output'.
For CROSSDJ try this:
Install 1.7.1 (the older version of Cross DJ).
Try to turn off every unnecessary applications, even networks and anty virus softwares.
In Cross DJ, Preference/ Audio - select U-Mix Control Pro as soundcard, and move the slider to 512. My old shitty laptop works with this buffer size, it should work for you.
