Error while opening Xdj-Xz Asio

Hi Kjetil,

Interesting name -- how do you pronounce that?

For the XZ, sometimes selecting the XZ ASIO a second time will cause it to load properly. In cases where that still doesn't work, please check that Windows has not selected the XZ as the default output device as it would prevent rekordbox from assigning the device for output.

Failing that, you can try following the instructions here to uninstall / reinstall the device drivers.
