Today I tested this on a different computer, my iMac. I got this to work properly on my iMac right away, but still not on my Mac Pro. Both have the same OS and the same version of Cubase. On the iMac, the “MIDI/Note Expression/Note Expression MIDI Setup” menu shows “X” for controllers activated, just as it shows in the owners manual. These can be activated/deactivated by clicking on the “X”. But not on my Mac Pro, where all controllers show “unavailable” instead of the expected “X”, and selections cannot be activated. Does this mean I have a corrupted file on my Mac Pro. If so, which one?
