I can't get signal to the mix inputs or tracks. have good signal on interface meter, and in UC pre amp gain, IO set up/ track record assign is good respectively. I have tried old and new songs as well as from the interface template list, still nothing. The selections for IO set up are gray, and if I change to a different color is shows a dull version in the matrix. had no problems before last update?
Mac, SO4, Quantum, DP88, all current and updated.
