Ok, I have the new elmod system with the blaster IV unit and I really like it alot. I have heard that it is possible to take sounds from other sources and install them in this system, but I am lacking any real experience doing this and don't want to lose the existing sounds by fiddling around.Is anyone out there that can give a complete tutorial on how this would be done and what the limitations are if any.I, for instance, wanted to take the sounds of a running tank on a youtube video and use them for my tank.Can this be done? Thanks as always for any input. I appreciate the help.
