PO 33 question(new user)

Hey there, I just got my PO33 today. I noticed when I am holding sound button, there are no sound sample from but all the video I watched shows suppose to have something from those numbers? Thanks in advance.

When getting a new PO33, it comes with 4 melodic, and 4 open drum slots to leave sample room for you to input your own stuff! When watching other peoples videos, rest assured, they probley have their own content sampled in already.

And if you want to be extra sure you have your original factory default settings.
