Hi, I really want to start experimenting with mixing audio in surround sound (true 5.1). Just wondering if anyone has done this already and can provide any tips on how to get started with it all. I have been looking at sound cards already, as I will need to upgrade, and figure the Turtle Beach Santa Cruz will do what I want, for a good price. Also, can anyone recommend software to help with the mixing/panning of the music tracks? I'm on a strict budget and want to do this as cheaply as I can. Thanks in advance.
