Actually, the MIDI nes 808 snare was resampled with Ableton's Simpler instrument, where i used a lo-pass filter to get rid of some of the high-end grit (although that is probably what i should be going for). The hats are also just some 808 hat sample (not from MIDI nes). I think i did this because the DCM channel only has mono output, so i could never have more than one drum playing at the same time. Also, for the portion where the key shifts to the relative major, i layered the snare with a generic 808 style clap. Maybe this is what is not working. I will massage it a bit though, and make the hit a bit more nuanced. :)
