Problem with midi

Hi Everybody, I’m new in Cubase (from Logic). I have the following problem. I have a midi track with some notes. When I press play and try to add notes (in real time) into another midi track - this track plays the notes that have the other track. It’s seems to be a problem with midi thru. I desactivated in midi record preferes midi thru but in this case the track does not recieve any midi (neither from my master keyword).

Any idea?

I think I changed something because It was working well but i didn’t know what

Hi and welcome,

Could you be more precise, please? What editor is open (of which MIDI track)? Where is Record Enabled?
