Another tip : you can find some MIDI files of tracks on the web (vgmusic.com, etc...) and take a look at the drums. Or like Palpable said, watch the demos that come with your DAW.
The drum programming will depend of the genre of the song you're mixing : the drum work won't be the same for a rock or a metal song for instance.
If you use FL Studio, you can learn some drums loops with the FPC Generator.
Great, I saw people using music hacks in Brawl but no one used OCR music. I want to see a battle while Black Wing Metamorphosis plays, would be purely awesome on Final Destination.
