Main problem I can see is shooting vertically at first !
Second is that you didn’t listened to me and you want to do everything at the same time.
I recommend again to START A NEW PROJECT, focus on a 1 bar midi sequence with 1 midi track only. You don’t need to go in ALL menus. Midi Note Setup suffice.
You have to set levels with GAIN (MIXER) or Model D level first, so check the red led with DIR set to 127.
After you can set a Thru track, set DIR to 0.
