Yeah, I found that after I posted, ........so I downloaded it and installed it, bit it didn't solve my problem. I did go into the Midi setup, and saw it there.....but the OS still doesn't have it as an "input" device. I launched GarageBand to see if it would maybe show up there even though it wasn't listed as an input device, but no, it didn't.
Well, I'll work on it and try to look around some more.
It's probably something I am doing wrong, and will stumble on it down the road, I hope.
