the free version has audio limitations ,, the demo version give full capabilities but time restricted ,,
if you are trying the software with a U-Mix controller with out the sound card ,,the controller will olny control the software
if you are having issues with the audio ,,you will need a sound card with two stero out puts ,, one for master and one for cue/monitor/pre fade listening ,,
this is inherent in any DJ software set up ,,so info is nessary to be able to get you up and running ..
Cross free and Cross demo are set up to give a feel for the software ,no regerstration needed ,, sooo let us know what going on
