Improper midi playback going from GP6 to BBManager

So i ripped the drum and bass midi tracks from Guitar Pro 6 of the song One of These Nights by the Eagles, and i was hoping to be a straight midi export and correct playback. But the drums do not play correctly nor is there any bass playback. Did some thread searching and now i believe i have to either change my kick to 35 or create a kit that will play kick on 36. Would it be easier to change the midi in FL studio( which i also have) to take care of the bass midi as well? and how would i go about configuring all the correct midi notes?

side note: i have been noticing some crackling/popping on playback for songs (almost like with a vinyl record) with the new firmware, is there a fix for that?
