I didnt get past 45 secs Kuwi...sorry but the beat is all over the place...Id seriously just be using midi files as the backbone to your beats just now as you are just not getting the timing right
what are you using as a controller?
I have an mpd24 that I picked up used for $75...maybe try one of these or an M Audio trigger finger to tap the beats in as whatever method you are using isnt working mate
