What does it mean ? An author of this remix opens the project and reviews his work. He answers some questions brought by community, he shares some tips (for example if you're interested about creating typical trance piano then this video may help you). The video is splitted into five parts (720p quality except first part), lasts about 50 minutes. Very good stuff especially if you're into trance. I like parts three, four, five the most.
I hope you ll enjoy it and you ll learn something new, the video is going to be pretty boring at some points so my advice is to watch it only if you really want to learn something new cause no one will give you back the 10 minutes you are losing watching this..
