Traktor 2 Loops

Traktor 2 Loops

Hey guys, it’s probably something stupid I’ve been doing, but I have no idea what exactly. I’m on Traktor Scratch Pro 2, using a launchpad as midi controller. Here’s my problem: I can just deactivate loops, but no activate them unless it is through the IN/OUT buttons. Any idea on why this is happening? :confused:

Oh, the funny thing: when there’s no song loaded, it works just fine.
