Removing Programs?

How do you remove programs from a project?...example( DRUM 1, DRUM 2, DRUM 3, DRUM 4....how would I go about removing say...DRUM 2 from a project?...without having to turn off the MPC?...I'm not trying to delete it from my hard drive, just remove it from the project I'm working on.

In the program screen, go up to the program name at the top of the screen. Scroll to a program. Hit open window and delete the selected program.

Thanks
