I recently bought a Behringer FCB1010 MIDI foot controller in hopes that I can use this in conjunction with my keyboard. In short, I want to program the MIDI to play a note/chord from my keyboard live. So when I'm on stage, I want to be able to push a button on the controller with my foot and have it play the note I have programmed into it so that I can play bass and the keyboards parts at the same time. I am a completely MIDI newbie, so any help would be nice.
Probably can't do that buddy, not with the type of controller you have. The only thing this MIDI controller will do is send a signal to the keyboard or amp and change the preset number.

What you want is something like that:

Which sends a note signal to the keyboard, but as you can see they're pretty expensive.
