I am in need of some assistance, and I'm hoping someone could help me please. I have installed all the software, as well as mainstage 3, but for the life of me can't get this to work right. Does midi controll center need to be installed if mainstage 3 is present. It appears that these two programs are conflicting with each other. I get weird results with mapping the kl88 rotary knobs to act as volume controls for each track. Additionally the volume control will not go to zero, but limits to some set volume. I really need some guidance here.
