Everything is in different keys!
Maybe this will help?

When you're using loops, make sure they are all in the same key, because otherwise the notes will "clash" which means "the quality of sounds that seems unstable and has an aural need to resolve to a stable consonance" Which basically means it hurts your ears and you want it to go away. (not that your music makes me want it to go away, I just copypasted off some website)
I use a different music software to you so I have no clue how it works, but try and make the loops say they are in the same key, it would sound so much better.
still cool though
Edit: What software do you use?
