Hey I have a MI-Audio ProFire 610 interface that I'm running into my mac desktop with snow leopard and I can't seem to figure out how to get my signal to come through. I have everything hooked up correctly, I go to system settings on the desktop and change my input to the profire and when I strum it shows good signal strength. Now I open up Logic and I can't get that signal to play through my speakers...very frustrating. Is there some simple step to this that I'm missing? Maybe a setting in Logic or something? Any help would be greatly appreciated!
