I do not know what the program Caustic3, but the hi-hat are hard to listen and the kick is strange, try to find more quality samples and it could be better. This song is hard to listen recommend it to amplify. Melody is good. Continue to work. ;) Failure teaches success.
I had no clue you could make stuff like this on android, sounds fucking great man.
It takes Caustic3 and allot of patience :D Thank you, I'm glad I didn't make your ears bleed!
