A logic midi question

I have just gotten logic and am trying to learn it so i thought id do a little remix. Now i downloaded a midi clip of the main melody on the internet, whipped it into logic and threw a sylenth1 on it. Now the midi clip itself has variouse things programmed into it, like for example it has a standard preset it always goes back to in sylenth. It did this in ableton too but you could click on the midi clip and change it, how do i do this in logic so the midi clip will play the patch i made and not always skip to the preset that is set in the midi file.
