MIDI issue

[R4yptor]

Hi, i see other people posting here with midi problems, so I'll post mine here too.

When I lay down notes right behind each other, they are all played as a single one, like if I did a singular long one. In one session it worked just fine, but in others not. I assume it could be fixed with editing through an event editor and tweak the start/ends of each note, but doing this over and over again would be really annoying. By the way, when I wanted to do so and opened the editor, all of the notes had the same start/beggining time value.

Any idea what's wrong here?
