The sheet is only the skeleton of the original, since the echo's and samplers are really missing and essential.

UPDATE Since I posted the sheet (step 2) I had to make a new update. Nils Frahm doesn't play the chord that connects the main pattern. It is 'just' a delay. This came clear by a remark of someone who noticed that it is a tough chord to play properly. The problem is solved: don't play it!
You can see it here:
• First, all I found in that beautiful chaos was this 4 measure pattern... I studied this one too.
• You could try to play the echoes, they don't sound as they are in the original. The echo comes a little earlier, before the beat.
