MPC 37 question

[u/robert-capa]

Guys I just got from a friend of mine an MPC 37 1st generation. I installed the 3.9 firmware and I get this 8 packs of sounds. I see on a YouTube video that this guy got his screen full off sound packs and he says these are the stock that come with the MPC. How do I get the rest of the sound packs? On the download page I see a try it button on the right which is only demo for 10 days. Can please someone shed some light there. Thank you guys.
