I'm believeing about getting a near new Hercules 4MX controller off of a friend.
Ive currently got an S4 and a MF. I want the 4MX to use on my desktop computer but for nothing else, it wouldn't even leave my room.
My plan is to use the 4MX with the Traktor pro s4 software, is this possible?

I want to do this so that I dont have to plug my s4 into my desktop, so that I can leave it in my music room with my laptop, edit my songs and add cue points, save them to an external hard drive and then when I need to take those tunes with the saved cue points, i'd be able to use them with my laptop on the S4 + MF by simply moving the external hard drive.

To simplify my question: Can I use a Hercules 4MX with the Traktor Pro S4 software on my pc and if so, would I need anything elce other than a USB cable and power point.
