SOLVED!! It was my own dumb mistake, but I'm sharing the solution in case this happens to someone else. My Mac broke and I'm on my Windows backup machine. I made the mistake of Adding the wrong type of device. I added an Instrument device when it should have been a Keyboard device. Don't know what I was thinking or how I made that mistake, considering how many times I've added MIDI devices. Anyway, I humbly share my solution, thanks to Lawrence Farr @ PreSonus Support.
