Midi Drum Mapping

After exporting a simple score as a midi file the drum kit sounds are not as I had written when trying to play back in the various DAW and midi editors I have on my computer. The bass and guitar are fine, perfect even. The drums instead of kick, snare and high hat are the novelty sounds in the GM soundset, whistle, beeps and such, in every app I import the file into.
Does Notion for iPad follow GM mapping ? Is it a bug?
I will admit that I am a bit of a novice at using a notation editor. Any help if I am doing something wrong would be appreciated.
