00:50:006 (1,2,1,2,1,2,1,2) - i got that this is for build-up, but i think its kinda too much for that, maybe try to overlap 00:50:220 (1,2,1,2,1,2) - to make less aim for this pattern?
remain -> It is not reasonable to use similar overlap pattern for different vocal snaps.
note: 1/4 vocals part 00:50:006 (1,2,1,2,1,2) - //vs// 1/2 vocals part on 00:54:506 (1,2,1,2,1,2) -
