1.8 in the left display is not sequencer edit mode, that's for sure.
If you turn the keyboard you should get 11 P. Then, if you switched to
sequencer edit mode the display would change to 11 50 01.
So it seems you have a more serious problem than just stuck switches.
Does the keyboard make sounds when you hit keys? If yes, do all of the
keys work, or just some of them? Which ones?
