Brizzy_b,
Just to update you, I went ahead and bought the Platinum version of Whitecap (also by SoundSpectrum) only to find out it is for “Personal / Non-commercial Use”. I am in talks with them right now to find out how much the Commercial version cost as they do not post it on their website.
Also, Whitecap even as a standalone was not able to “hear” the music I was playing through Virtual DJ. To get it to work I had to split my line out of the computer and reroute the sound back into the Line In so that Whitecap could hear it. Worked fine after that, just made the connections a little more complex.
