Change/Replace instrument by program change

[liam_1a]

I'm new for ableton live. Until now I used MainStage to play live.
In mainstage there is a feature which called "patches". So, you can add instruments and effects for each patch.
then you can change "patches" by program change trigger(external keyboard).

I want to know how to do that in Ableton live?

I guess this might be it (I am new as well, so I hope I got it right! Cheers for helping each other!):
