Help needed using foot controller and Ableton Live

[pangea2006]

Hi there!
I would really appreciate if someone can give me a hand with this:
I'm a guitarrist trying to make use of Ableton Live by using a foot controller (Nobels MF-1)
I'm sending MIDI messages to Ableton through my MIDI interface (emagic MT4) and it looks that Ableton is receiving the MIDI as I see that little box flashing on the right hand side of the screen..
However, I can't map or change any parameter with the pedals...
I think that this foot controller sends program changes only... I
s that a problem?
I would like to trigger clips, scenes, looping, etc with the pedals....
Any help???

Cheers
Eliseo
