[Cubase SX 5] (Groove Agent ONE) Chopping a sample

Hey there!

I’m trying to chopp a sample into pieces to use it in the Groove Agent ONE on different pads. I searched YouTube and found this tutorial that explains “one way” to do it:


The fact is that at 3:30 when he says to “drag and drop” the chopped sample to Groove Agent, unlike him, when I try to do it, I get the typical signal “forbidden” at cursor and I’m not able to.

Anyone know what the hell’s going on?

Thank you very much!
