Oh dear... id-iots like you just love wasting people's time.
Armin's music doesn't have to be stolen to be listened to. http://www.youtube.com/watch?v=TxvpctgU_s8
FWIW, unlike like you, he is a hard working guy with talent and massive 19,102,421 views.
And this is the reason why myself and millions of others love the reverb he is using and we want to get a similar effect. Don't care if you like it or not, I'm working on it.
If you have no ideas, (You and other geniuses with too much time and to little talent!) that's fine. Try achieving what Armin has achieved.
I worked it out by myself (nearly) anyway but I just want to get other people's opinions and suggestions.
Others - not yours cause you're not polite and obviously lacking any relevant knowledge.
