Akai MPC 2000XL: How to set up mute assign (drum pad cut off samples, "mute group")

This is one of the most asked questions for MPC-2000XL. I could not find any video on YouTube that answers the question very briefly, so I decided to create a very short video about it. There is no mute group function on MPC-60, MPC-3000, MPC-2000 series (which is available on MPC-1000, MPC-2500 and later model.)
