Hey, I hope you can help me out. I just spontaneously bought this MM Electronics MP175 at a flea market.

Now my question is, does anyone know what I need to theoretically make techno music with it?
How could I use samples, if that's even possible?
Or is it basically like a regular mixer (like the Xone 92, for example) and you have to connect a CDJ, XDJ, or something similar?

I have absolutely no clue. If you have any idea what I'm talking about, I'd really appreciate some help.
