Barry, how easy would it be to make an option in the settings screen to choose which sound card you want to use? I'm a mobile DJ and i'm toying with the idea of having my main PC set up as master with freebox using main sound card, and my DJ software linked to line in from a usb second card...or something along those lines. I'm making a freestanding selector that doubles as a karaoke monitor so people can select their own tunes! Gonna use a remote controlled vga switch in the cab, if i can find one that is...
