War Documentary!:Assign mp3 to a keyboard

[wikibox]

hello everyone,
i am new to midi and i am editing a world war 2 semi documentary-radio novel with footsteps explosions and a plethora of effects i generated in mp3, i have an axiom 49 piano from m audio and i want to assign some of the mp3s i already have, to be triggered by assigning them to specific keys...that way i will be able to sync some efects with the images by doing it "on the fly" as the video plays, i generate the soundtrack

my question is very simple:

HOw do I assign mp3 files to my midi keyboard?
Is there a plug in that does it?

You need a sampler to do that... but, you know you'll be surprised at how noticeable it is when a sample is just a frame or two off from the action.... for this, I'd just use the video editing software and add the effects one at a time where you need them.
