Here's another problem that might be related to they keyboard. It only enters data on channel one. I used to be able to double click on a logic track and I'd see the piano roll image of midi notes on that track, so I could edit. Now with only one track selected, Logic insists on showing me ALL the midi notes. Is it attempting to show me all the notes on midi channel one? Regardless of the input, can I change the midi channels of the tracks? I went in to score mode to layout of a track and changed it's midi channel. As a result ALL NOTES ON THAT TRACK DISAPPEARED COMPLETELY. i changed it back to midi channel one and the notes were restored. Kinda unsettling. Also for some reason, Logic erased all my lyrics in this particular song, now I have to put them all back.
