I don't have the answer, but I just wanted to say that's a really neat feature...

I hope someone is able to help you with this. I wish more keyboards allowed that function. I use a Zoom drum machine for all my drum tracks, and it too has that feature where you can play any sound with the pedal... Again hope somone can help..
