Reply to Launchpad as drumpad?

So...

I have a launchpad and currently only use it while live DJing but I am starting to get into production. My buddy and I want to start making our music and I really want to use my launchpad to record drum loops as I do them live. I Have seen many people doing remixes using stems from here and putting them on Youtube, but i just can not seems to figure out..

Anything would help

Thanks guys...
