[One Winged Angel]

I don't think that wall is fixable in the sense that it shouldn't have a 2 frame gap at some point. At 220bpm there's going to be an additional frame gap approximately every 22 16th notes and the wall duration is longer than that. I suppose you could force the gap at the start of a new roll instead of in the middle of one, but since the gap is already luckily occurring between hands I don't think that would ultimately impact playability much.
