Cubase 7.5 record mode

Hi,

I’ve changed the record mode in the transport panel, now my midi tracks are cut if i move another one into the others, or if i record inside the tracks.
It’s very anoying, because i can cut tracks just with a copy and bad paste.
Which is the record option concerned by this behavior?

Thanks in advance,
Have a good day,

Hi,

Was not the record mode, but preferences midi edit part, delete overlap!
