I don't know if MAGIX is still updating acid 11? and if they have any feedback from the users

But there is one thing really problematic with the loops under all acid 8 9 10 11....

the samples in loop mode from 150bpm onwards are no longer synced correctly! they all have to be doubled from 4beat to 8beat or 8beat to 16beat or16beat to 32beat or 32beat to 64beat... a shame when it was acid that created the loops synced....
under bitwig ableton FL the loops are all synced on their bpm

And not under acid...
from 150 bpm to 300 bpm you have to set them all 1 by 1.....

so for the DNB , the trap hybrid , the hardstyle , the hardcore
you have to sync all the samples yourself 1 by 1.....
