not the best, but there IS potential.
first off i would have suggested having the audio file play 4 times then loop, as audio cuts off poorly in NG audio portal. second, there is only one main instrument, and it only plays half the time, it should play a little more, though i get the feel you were going for with this loop. also the hits at the end sound hokey.
last suggestion for the moment would be that your triplets (well, triplets with one note empty) one of the notes feels a little off and throws me off throughout the loop.
I dont know why you are using midimaker, there are lots of torrents for Fruity loops on the internet, as well as other programs that I havent used (i think reason is hared to crack)
