Too long
I didn't really like this that much, sorry if that bothers you but I'm just being honest here. It was a little slow for my taste, which I am not taking a lot off for. What I mainly took off for is pretty much what the guy said below me. It is waaay to long. I see that you said you were going for the repetitiveness and that's fine. However if you do a track thats supposed to be that way, I don't think it has to be anywhere near this long. Especially since the audio portal is set to auto loop any track. I think it would be much better if you just ended the track on a note that flows back into the beginnng well so this way when it loops it sounds like it never stopped.
