Live Sets

Whats up everyone. Ive been looking at some live sets on youtube and ive noticed that some of these cats using the Mpc 2000 can tap on a pad and take away and element. Does anyone know how to set that up. Im Using the 2000

I think you're describing the track mute window! Highlight the track on/off and hit open window. The 2k is the first MPC to have this it is major fun.
