Hello, I am having issues with the Mojave OS and the M-Audio fast track ultra I have obtained. I have downloaded the drivers and still am not able to get the signal to show up in the recordings. I am trying to multitrack record and have enabled the channels I am working on. The green lights on the interface show the signal is there and I can see the signal on the M-Audio board, how do I get it to flow through to the channels on garageband?
