EFFECTS ON SEQUENCES

HOW DO YOU ADD EFFECTS TO A SEQUENCE WITHOUT CHANGING OTHER SEQUENCES

I KNOW WHEN YOU ADD EFFECTS IT'S TO THAT PARTICULAR PAD.
MY PROBLEM IS THAT I DON'T WANT TO CHANGE THE OTHER SEQUENCES ON OTHER PADS.
I'M TRYING TO KEEP MY EFFECTS SEPARATE.

PLEASE HELP

Get an external effects processor and stop shouting, I hear very well without my glasses, thank you.
