muting one pad with another

How do you do this? Basically I want to mute one pad w/ a sample playing as soon as I trigger a new pad.

I want to be able to mute one sample just as soon as I hit another pad w/ a sample on it(the new second pad will mute the first as soon as it's presses)
How do I do this????

Hit the program button> then hit kg mix (f2) Select the drum program>
Hit the pad you want to mute>it will be highlited on screen> then go to the far right of the screen where it says mute group and set it to 1> hit the next pad you want to mute> it will be highleted on the screen>again go to the far right of the screen where it says mute group and set it to 1. You have now assigned both pads to a mute group (there are 64 possible mute groups)

Peace

thanx dawg..Imma try it out.
