I just bought a Mackie ProFX12, I connected it to my mac book pro, and the volume controls in both GB '09 and the midi controls are locked out

Hey thank you so much for the link,
I think my problem is the volume on the disabled slider is set very low. And while I can increase the gain and slider on te mixers, I am then running very hot, in order to use garage band. The Volume levels are okay, in Soundbooth, Audacity, and other devices, just apple based products have the control set very low and locked. It wouldn't be a problem if it was just locked, but since it is locked very low, I am running into a problem. Sorry I should have said that in the beginning.
