So I'm reading your previous comments to reviews and came across one that makes you look like a pretentious prick. Someone mentioned that there are no instructions, (which there aren't AND you should have provided) so you go on to say insults to the effect that, "Even a monkey could understand" "crappy monitor", "Learn how to learn."
But then I come across another negative review and your like thanks for the critique. Which is it? Either you can handle critique, or you can't.
To the actual review: little variation, no instructions, and pretty bland. Not front page material in my opinion. One of the largest parts of music, the drums, have the same notes/tempo except variant 4, and even that only has one little change.
